Pharmaceutical Packaging Technology

Ayush Garg, Arti Thakkar

Packaging is designed to contain a product so that it is unable to interact with the environment. After containment protection is most important function of packaging. The product must be protected against the physical damage, loss of content or ingredients and intrusion of unwanted component of the environment such as water vapour, oxygen, dirt and light. An important role of pharmaceutical packaging is to transform the formulation into an attractive and marketable product. Pharmaceutical companies increasingly are working to improve productivity and reduce costs in their manufacturing and packaging operations. Expanding markets and innovative marketing strategies have led to an increased demand in packaging products. So many issues regarding the pharmaceutical product like stability, sell, patient compliance etc are related with the packaging and in regard to this; present review is done on the various advancements in the packaging techniques and selection of packaging material.

Solid Dispersions An Advancement in Solubility Improvement; Strategy, Mechanism and Characterization

Amit Kumar, Raj Kumar Narang, Arti Thakkar

Solubility is the phenomenon of dissolution of solid in liquid phase to give a homogenous system. Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response to be shown. Poorly water soluble drugs often require high doses in order to reach therapeutic plasma concentrations after oral administration. Low aqueous solubility is the major problem encountered with formulation development of new chemical entities. Any drug to be absorbed must be present in the form of an aqueous solution at the site of absorption. The ability to increase aqueous solubility can thus be a valuable aid to increasing efficiency and/or reducing side effects for certain drugs. This is true for parenterally, topically and orally administered solutions. The solubility of drugs is defined according to (bio-pharmaceutical classification system) BCS classification system which divides drugs to different class according to its solubility. Solid dispersion is defined as dispersion of one or more active ingredients in an inert carrier or matrix known as solid dispersion. Solid dispersion reduces the particle size and changes the micro environment of the drug particle, increases the rate of dissolution and absorption and thus changes the biopharmaceutical properties of poorly water soluble drugs. The solid dispersion method, by which a drug is dispersed in a carrier to make it amorphous, is one of the pharmaceutical approaches most commonly employed to enhance bioavailability of poorly water soluble drugs. Various pharmaceutical approaches for the preparation of SDs, including co-precipitation, lyophilization, spray drying, solvent evaporation, fusion and powder mixing methods, have been reported. It’s a new and efficient technique to improve the solubility of poorly soluble drugs.

Aerogel- A Recent Innovation In Gel

Viren Dekavadiya, Sachin Patel, Upendra Patel, Ghanshyam Patel, Bhavin Bhimani, Dhiren Daslaniya

Aerogel is world’s lightest material and drug delivery system. Aerogel having more than 15 entries in Guinness Book of the world’s record is very low density solid state gel which is derived by replacing the dispersion phase of gel with gas. Aerogels are prepared by sol-gel process to extract liquid component of gel through super-critical drying. This allows the liquid removed without causing the solid matrix in gel to collapse due to capillary action. Aerogel possesses some properties like lowest density, lowest optical index of reflection, lowest electric constant and highest specific surface area. Materials used for preparation of aerogel include silica, metal oxides, organic and biological polymers, carbon nanotubes etc. Both hydrophilic and hydrophobic gels can be prepared. Solvents used for preparation of gel are explosive so, they are replaced by non inflammable liquid carbon dioxide. Applications of aerogel are very wide. Aerogels are used as a composite, as an absorbent, as a sensor, as a catalyst, as a thermal insulator, for improving dissolution properties of some drugs etc.

Current Concepts in Diagnosis and Management of Peptic Ulcer

Trilochan Satapathy, Prasanna Kumar Panda

Peptic ulcer disease had a tremendous effect on morbidity and mortality until the last decades of the 20th century, when epidemiological trends started to point to an impressive fall in its incidence. Two important developments are associated with the decrease in rates of peptic ulcer disease: the discovery of effective and potent acid suppressants and of Helicobacter pylori. With the discovery of H. pylori infection, the causes, pathogenesis, and treatment of peptic ulcer disease have been rewritten. The inhibition of gastric acid secretion is a key therapeutic target for the ulcer diseases (viz., peptic, duodenal ulcers or that through H. pylori infection), gastro esophageal reflux disease (GERD), Zollinger–Ellison syndrome (Z-E), and gastritis. Currently this is achieved by blocking the acid secretary effect of histamine (HA) through the use of H2-receptor antagonists or the irreversible H+/K+-ATPase inhibitors, popularly referred to as proton pump inhibitors (PPIs). The incidence of ulcer diseases shows global variation and their treatment should be designed to alleviate the symptoms. Key words: Peptic ulcer, Helicobacter pylori, Zollinger–Ellison syndrome

Niosome: A Targeted Drug Delivery System

Darshan Kamani, Hiral Shah, Ragin Shah, Jignesh Solanki, Sunita Chaudhary, kinjal Sanghvi

Drug targeting is the ability to direct a therapeutic agent specifically to desired site of action with little or no interaction with nontarget tissue. Niosomes are one of the best carriers for drug targeting. Niosomes are microscopic lamellar structures formed on admixture of non-ionic surfactant of the alkyl or dialkyl polyglycerol ether class and cholesterol with subsequent hydration in aqueous media. Niosomes are biodegradable, relatively nontoxic, more stable and inexpensive, an alternative to liposomes. Niosomes can be SUV (Small Unilamellar Vesicles), MLV (Multilamellr Vesicles) or LUV (Large Unilamellar Vesicles). The method of preparation of niosome is the based on liposome technology. The basic process of preparation is the same i.e. hydration of the lipid phase by aqueous phase. Niosomes are characterized by vesicle size, bilayer formation, number of lamellae, membrane rigidity and entrapment efficiency. A method of in-vitro release rate study includes the use of dialysis tubing. Niosomal drug delivery is potentially applicable to many pharmacological agents for their action against various diseases including cancer and leishmaniasis.

A Basic Approach on Sustained Release Drug Delivery System

Kapil Patil, Prashant Patil, Javesh Patil, Sunil Pawar

The oral route of administration is considered as the most widely accepted route because of its convenience of self administration, compactness and easy manufacturing, in which the sustain release drug delivery replaces the conventional administration of drug by delivery system. Recently, greater emphasis has been placed on controlling the rate and or site of drug release from oral formulations for the purposes of improving patient compliance and treatment efficacy, solving problems concerning targeting of a drug to a specific organ or a tissue and controlling the rate of a drug delivery to the target site. Matrix system are favored because of they are easy to formulate, and showing better patient compliance, effective etc, than ancient drug delivery, which showing many drawbacks like repeated administration, fluctuation in drug plasma level etc.; developing oral sustained release matrix tablet with constant release rate has always being beneficial to the pharmaceutical technologist. Matrix type drug delivery systems are an interesting and promising way for developing an oral controlled release system, which will maximize the pharmacological benefits and minimize the potential side effects. The matrix tablet releases the drug in continuous manner like diffusion and dissolution controlled way. Hydrophilic polymers with high gelling capacity are of particular interest in the field of matrix tablet. Key words: Sustained release, Oral formulations, Hydrophilic polymers, Matrix tablet.

Review on Nail (Transungual) Drug Delivery System

K. A. Suryavanshi, P. R. Basrur, R. G. Katedeshmukh

Nails are the hard and durable epidermal appendages structurally horny in nature. Nail plate is responsible for the penetration of the drug across it. There are number of formulations with antifungal agents viz. gels, creams and oral antifungals for the treatment of transungual infections. Among these entire nail lacquers is a new concept in treating nail infections. These nail lacquers are effective as monotherapy in treatment of superficial, distal and subungual diseases. The main purpose of topical nail preparations is to protect the nail plate and enhance beauty of nails. The medicated lacquer preparations are generally used in fungal diseases. Use of this system avoids oral toxicity of anti fungal drugs. The main challenge associated with developing nail lacquers for the treatment of nail disorders is to deliver the active concentration to the site of infection which is often under nail. Penetration of topical antifungal through the nail plate requires a vehicle that is specially formulated for transungual delivery. In this article we have tried to emphasize on need to develop nail lacquer for a promising antifungal treatment. This field could be explored for the treatment of Psoriasis24 and Onychomycosis.24

Cylma Menezes, Kunal Gupta, Satyanarayana D, Jagadish V Kamath

The anthelmintic activity of fruit extracts of an Indian Medicinal plant Syzygium cuminii Linn. was evaluated on earthworms of Pheretima posthuma. This is because earthworms have anatomical and physiological resemblance with that of intestinal roundworm parasites of human beings. Here anthelmintic activity of the herb was determined by time taken for paralysis and death of earthworms after suitable treatment and comparison with standard drug piperazine citrate. The ethanol extract of Syzygium cuminii fruit at concentration of 50 mg/ml showed most pronounced activity. The results suggest that fruits of Syzygium cuminii possess anthelmintic activity. There is scope for future study on this plant.

Preparation of Superporous Hydrogel Composites Drug Delivery System Using Metronidazole as a Model Drug

Mowafaq M. Ghareeb, Ali A. Hamid, Alaa A. Abdulrasool

The aim of this study is to prepare gastroretentive dosage form based on the super porous hydrogel (SPH) composites using metronidazole as a model drug for eradication of H pylori.Blowing technique was used to prepare SPH composites. The latter was used as a body for the drug delivery system. The core was made from matrix granules. Four types of retardants (Beeswax, carnauba wax, ethylcellulose, and Eudragit®RS) were used to prepare the granules by fusion for waxes and wet granulation methods for other polymers. For each retardants, two ratios (1:1 and 1:0.5 of drug: retardant) were used. Simple new method for insertion of core inside the SPH composite by using syringe with wide end opening without use of glue to close the insertion site was applied. The system was characterized by scanning electron microscopy, FT-IR. Also swelling, mechanical, and dissolution properties were studied. Scanning electron microscopic images clearly show highly porous structure and interconnected channels. FT-IR study confirmed the formation of crosslinking poly (acrylamide- sulfopropyl acrylate) SPH composites. The delivery system achieved the equilibrium swelling in about 3 minutes with swelling ratio of 10.45 ± 0.9 and penetration pressure of 483.34 ± 48.0 cm H2O. The results showed non-significant (p > 0.05) difference between loaded and unloaded SPH composites regarding mechanical and swelling properties. A significant difference (P < 0.05) was found among the cumulative amount of metronidazole released with time depending on the nature and ratio of each retardant. It can be concluded that the proposed drug delivery system based on superporous hydrogel composite is promising for gastroretentive stomach specific delivery of metronidazole.

Olorunfemi O. Joyce, Nworah D. Chinwe, Egwurugwu J. Nnabufe, Woyike A. Ovutor, Adienbo O. Macstephen

In the present study, the effects of pre-treatment with catecholamine on indomethacin-induced ulcer were studied. Rats were exposed to various treatments with epinephrine and dopamine 30 minutes before ulcer was induced using NSAID (indomethacin). Experimental ulceration was induced in fasted rats using Indomethacin (40mg/kg.p.o). Four hours later after indomethacin administration, the stomachs were opened under thiopentane anesthesia and the ulcer area scored by planimetry. Sections of the stomachs were prepared for histology and stained for apoptotic cell count. Acid secretion was also studied in the control and treated animals by pylorus ligation technique. Indomethacin treatment resulted in the formation of ulcer with ulcer index of 5.0±0.5 while the pre-treatment with catecholamine significantly reduced ulceration episodes (epinephrine: ulcer index=3.0±0.7, dopamine: ulcer index=2.0±0.7, p

Comparative Anti-Diabetic Effects of Ocimium Gratissimum, Vernonia Amygdalina and Insulin on Testicular Architecture in Stz-Induced Diabetic Rats

Olorunfemi O. Joyce, Nworah D. Chinwe, Egwurugwu J. Nnabufe, Pughikumo D. Tabot, Joffa P.P. Kwaku

To study the effects of ethanolic extracts of Vernonia amygdalina(VA) and Ocimum gratissimum (OG)on the testes of diabetic rats, thirty-two male rats were used. Control consisted of eight (8) rats which served as non- diabetic control, receiving sodium citrate daily. The remaining rats were injected intraperitoneally with streptozotocin(65mg/kg) to induce diabetes. The rats confirmed diabetic were randomly divided into three experimental groups (1, 2 and 3) made up of eight rats each. Group 1 received 6IU/kg of insulin. Group 2 was given 100mg/kg body weight of Vernonia amygdalina and 200mg/kg body weight of Ocimum gratissimum combined daily. Group 3 served as the diabetic control and was given distilled water. The entire investigation lasted for 6 weeks. Results revealed typical testicular architecture in the normal control. Diabetic control exhibited alteration of germinal epithelium, distortion of seminiferous tubules as well as vacuolation of seminiferous tubules. The effects of the extracts on diabetic rats’ testes showed improvements compared to the diabetic control group. It is therefore safe to speculate that the extracts of these plants used especially when combined exert some significant improvement in combating the adverse effects of diabetes on the testes of male rats.

Sodium Alginate-Based Microspheres of Salbutamol Sulphate for Nasal Administration: Formulation and Evaluation

Ragwa M. Farid1 ⃰, Mohamed A. Etman, Aly H.Nada, Abd-Elazeem A. Ebian

Nasal delivery protects drugs like salbutamol sulphate (SS) from hepatic first-pass metabolism. The study aimed to formulate mucoadhesive sodium alginate (SA) microspheres loaded with (SS) by emulsion cross-linking, with mucoadhesive polymers, for potential nasal delivery by-passing first-pass metabolism. Relevant physichochemical properties, in vitro release and irritation in rabbits were investigated. Stirring rate and cross-linking time affected microsphere parameters. Microspheres were spherical in shape, discrete, with smooth and porous properties favorable for intranasal absorption with high drug-loading of 78.7 %. Mixed-polymers microspheres exhibited higher degree of swelling. Kinetic analysis of release data showed a case II release kinetics for alginate microspheres, and anomalous mechanism for other mixed-polymers formulae. Pronounced sustained drug release over 8 hours was exhibited upon incorporation of Carbopol® 934 and Hydroxypropyl methyl cellulose. The formulated microspheres showed high swelling ability and good mucoadhesion, offering a good potential for future in vivo study to confirm safety and avoidance of first-pass metabolism.

Hazim J. Al-Daraji

This study was conducted to determine the probable suppressive role of certain grape components on detrimental effects of lipid peroxidation which accompanied with liquid storage of roosters' semen. A total of 60 White Leghorn roosters, 32 weeks of age, randomly divided into 6 groups of 10 roosters each were used in this experiment. Semen samples for each treatment group were collected on a weekly basis during the whole experiment period which lasted 10 weeks. Treatment groups were as follows: T1 = fresh semen (control group); T2 = semen diluted 1: 1 with Lake diluent (LD) alone; T3 = semen diluted with LD and supplemented with 4 ml of grape flavonoids; T4 = semen diluted with LD and supplemented with 4 ml of grape phenols; T5 = semen diluted with LD and supplemented with 4 mg of grape seed proanthocyanidins extract (GSPE); and T6 = semen diluted with LD and supplemented with 4 ml of grape juice concentrate (GJC). Results revealed that after 1, 7 and 14 d in vitro storage, the supplementation of roosters' semen diluent with certain grape components (T3, T4, T5 and T6) resulted in significant (p< 0.05) improvement in mass and individual motility of spermatozoa in comparison with control group (T1) and significant improvement in regard to percentages of live spermatozoa and normal spermatozoa and acrosomes compared with T1 and T2 groups. Besides, T3 and T5 groups surpasses all other treatments involved in the present study as concerns all of semen traits involved in the present study. In conclusion, grape components especially flavonoids and GSPE gave a good suppression against the detriments of lipid peroxidation during in vitro storage of roosters' semen for up to 14d.

Polymeric Film Devices as Transdermal Therapeutic Systems for Diabetes.

Omnia Sarhan, Mahmoud Mokhtar, Mahmoud Mahdy

The purpose of the present investigation was to enhance the dissolution properties and bioavailability of a poor water soluble drug (Glibenclamide) by matrix-type transdermal films. Eudragit S 100 (Ed S100) and Hydroxypropylmethyl cellulose (HPMC) were used individually or in mixtures to formulate the transdermal devices by solvent casting method. The physicomechanical evaluation of the polymer matrices was performed. The prepared films showed good physicomechanical characteristics as Ed S100 percent increased, where HPMC lowered these characters. In-vitro release studies of ideal films were evaluated and the results revealed that the amount of Glibenclamide released was affected to great extent by the polymer type and also the solvent used. HPMC films showed high release rates of the drug where Ed S100 retards and control the drug release rates. HPMC mixtures with Ed S100 in 1:1 ratio released about 100% of the drug after 6 hours. In vivo evaluation of the prepared films was investigated by testing the hypoglycaemic effects of the drug after transdermal application to diabetic rats. The observed results simulated that obtained after oral administration of Glibenclamide in a dose of 5 mg/kg. The obtained results revealed a good promise of using Glibenclamide via transdermal route which could be of excellent benefit when oral route is unavailable.

Satranidazole Biodegradable Inserts For Local Long Term Treatment of Periodontitis

Shankrayya M, Mukthar Ahemad Javali, Santoshkumar R G, Venkatesh J S, Nagesh C

An attempt has been made in the present research to formulate periodontal inserts of Satranidazole (STZ) to increase residence time and prolong drug release. The periodontal inserts were prepared using chitosan, a natural biodegradable polymer. Chitosan inserts containing Satranidazole (10%, 20% and 30% to the weight of polymer) were prepared by solution casting method using 1% v/v acetic acid in water. Further inserts containing 30% Satranidazole were cross-linked by exposing to the vapours of 2% v/v glutaraldehyde in water for two different time period of 2 and 4 hours to retard the release of drug. FTIR and DSC studies revealed that there was no interaction between drug and polymers. The inserts were then evaluated for their physicochemical parameters like uniformity of thickness, weight, folding endurance, % moisture loss, tensile strength; drug content and in vitro drug release studies. In vitro drug release data indicated that the films showed an initial burst release followed by sustained release of the drug. The drug-loaded films that were not cross linked had released the drug up to 10 days and the films which were cross linked for different duration showed a progressive fall in the release of the drug and extended up to 18 days.

Efficacy of Ellagic Acid on Biochemical Parameters and Histopathological Description in Streptozotocin Induced Diabetic Rats

Ganesan Kanchana, Palanisamy Malini, Wilson Jerine Shyni

The present study was aimed to evaluate the effect of ellagic acid on physical and biochemical parameters and histopathological changes in tissues of streptozotocin (STZ) - induced diabetes in wistar rats. Diabetes was induced in wistar rats by single intraperitoneal injection of STZ (45mg/kg body weight). STZ-induced diabetic rats showed a significant increase in kidney weight, food intake, water intake, blood urea, serum uric acid and creatinine and a significant decrease in body weight, liver weight, plasma total protein and albumin when compared to normal rats. Oral administration of ellagic acid (50 and 100 mg/kg) in STZ-induced diabetic rats for a period of 35 days significantly improved body weight and reduced food intake and water intake when compared with diabetic control rats. Ellagic acid administration in STZ-induced diabetic rats restored the liver and kidney weight and also the biochemical parameters to near normal when compared to diabetic control rats. The results of the present study clearly show the preventive role of ellagic acid in STZ-induced diabetic rats. Results obtained from histopathological studies also supported the anti-diabetic effect of ellagic acid in STZ- induced diabetes.

Formulation and Evaluation of Nizatidine Floating Tablets

Ashish Kumar Garg, Gaurav Kapoor, Rajesh Kumar Sachdeva

The present study aims at the formulation of a floating drug delivery system of an antiulcer drug nizatidine using different grades of HPMC (K100, K4M, K15M & K100M) and an effervescent agent i.e. sodium bicarbonate. It was found that the release rate of nizatidine from tablet formulations prepared from HPMC K100LV was very high as compared to that from formulations containing higher viscosity grades namely K4M, K15M and K100M. In the current study, it was also found that overall rate of drug release tends to decrease with increase in concentration of HPMC. These observations are in agreement with the results reported in literature i.e. with the increase in polymer concentration and viscosity grade, the viscosity of gel layer around the tablet also increases leading to enhanced diffusional path length for the drug to follow and thus limits the release of active ingredient.

Iswaryakarapareddy, Imrankhanpatan, Nagarjuna Reddy3. K, Subhojit samanta, C.M.Vaijayanthi, Mrs. Ramya

Armodafinil is very slightly soluble in water; hence the drug may be slowly or incompletely dissolved in the gastro intestinal tract. So the rate of dissolution and therefore its bioavailability is less. In the present study an attempt has been made to prepare immediate release tablets of Armodafinil by using different superdisintegrants (croscarmellose sodium, pregelatinized starch and Avicel pH 101 to increase the rate of drug release from dosage form or the dissolution rate and hence its bioavailability. The prepared granules and tablets were evaluated for their physiochemical properties and in-vitro dissolution study was conducted for the prepared tablets. The in-vitro dissolution studies shows the release in the following order of superdisintegrants is croscarmellose sodium> Pregelatinized starch> Avicel PH 101. It was concluded that the immediate release tablets with proper hardness, disintegration time and with increase rate of dissolution can be made using croscarmellose sodium as superdisintegrants (F9). The formulation F9 was selected as an optimized formulation for stability study and the in-vitro dissolution study showed that was no difference in percent of drug released between 1st month and 3rd month sample.

Formulation and Evaluation of Mouth Dissolving Tablets of Meloxicam Using Co-processed Superdisintegrants

Manoj M. Nitalikar, Dinesh M. Sakarkar

In the present study, novel co-processed superdisintegrants were developed by solvent evaporation method using crospovidone and croscarmellose sodium in the different ratios (1:1, 1:2 & 1:3) to formulate mouth dissolving tablet formulations of Meloxicam. The poor aqueous solubility of Meloxicam makes its absorption as dissolution rate-limited and thus delay onset of action. Mouth dissolving tablets of Meloxicam were prepared using the above co-processed superdisintegrants and evaluated for different parameters. Effect of co-processed superdisintegrants (such as crospovidone and sodium starch glycolate) on wetting time, disintegrating time, drug content and in-vitro release parameters have been studied. Based on in vitro dispersion time (approximately 19 sec), promising formulation CP1 was tested for in-vitro drug release pattern. Among the designed formulations, the formulation (CP1) containing 4% w/w of co-processed superdisintegrant (1:1 mixture of crospovidone and sodium starch glycolate) found as the best formulation based on drug release characteristics. From this study, it can be concluded that dissolution rate of Meloxicam could be enhanced by tablets containing co-processed superdisintegrant.

Rajeshwari Shastry, Gopalakrishna H.N, Ullal S.D, Sindhu KC, NithyaRavindran, Mukta N Chowta

Depression is an affective disorder characterized mainly by change in mood and is associated with significant morbidity and mortality. A number of drugs are used for treatment but their adverse effects compromise the therapeutic effects. Thus search for an agent with minimal adverse effects and maximum therapeutic benefit is going on. In Asia, Camellia sinensis (CS) popularly known as green tea is widely used as a beverage and has been reported to have antioxidant property.On this basis, the present study was designed to evaluate the antidepressant activity of Camellia sinensis on albino mice. The antidepressant effect of Camellia sinensis was examined using two behavioral models, the forced swim test (FST) and tail suspension test (TST) in albino mice. The effect ofethanolicextract of Camellia sinensisin three different doses (3.3, 16.5 and 33mg/kg) was compared with the standard antidepressant, imipramine (10mg/kg). Antidepressant effect was studied both on acute and chronic administration (14 days) of Camellia sinensis. Acute and chronic treatment with Camellia sinensis reduced duration of immobility in FST in a dose dependent manner. In TST acute treatment with Camellia sinensis reduced duration of immobility at 3.3 & 16.5 mg/kg; whereas on chronic treatment CS reduced duration of immobility at 3.3 & 33 mg/kg. Acute & chronic treatment with Camellia sinensis produced antidepressant effect in both FST & TST models of depression in mice.

Development of Discriminative Dissolution Medium for Valsartan

Pavankumar Alapati, Vankayalapati. SaiKishore, J. Satyanarayana, TEGK Murthy

Dissolution is a valuable qualitative tool to asses the biological availability and batch to batch consistency. Discriminative dissolution mediums are highly desirable to differentiate the dissolution profiles of two identical products which are varied in their composition, formulation technique, manufacturing process and site of manufacturing. The objective of present investigation is to develop discriminative dissolution medium for valsartan by using two different marked formulations named as VALZAAR and VALENT. The dissolution studies were performed in four dissolution mediums (0.1N HCl (pH 1.2), pH 4.5 acetate buffer, pH 6.8 phosphate buffer and distill water) at three different agitation speeds (50, 75,100 RPM). Model independent approaches such as difference factor (f1) and a similarity factor (f 2) were used to compare dissolution profiles. Among all the cases in pH 6.8 phosphate buffer at 100 rpm drug releases at faster rate and best suited to maintain sink conditions. Irrespective of other cases pH 4.5 acetate buffer at 50 rpm was considered as a discriminative dissolution medium because of its lesser similarity factor and higher difference factor. From the present experimental investigation the rate of dissolution was found to be influenced by pH of the dissolution medium and speed of the agitation. The usage of 4.5 acetate buffer at 50 rpm was found to be a discriminative dissolution medium for valsartan tablets.

Changes in the Polyphenols and Alkaloid Compositions of processed Tea Leaves due to Variations of Fermentation Temperature

G. Ramu, K. Janakiram, G. Senthilkumar, B. Ramesh

The changes in polyphenols and caffeine alkaloid compositions of black tea, due to the variations of fermentation temperature were investigated. Black tea was manufactured by fermentation at various temperatures such as 26oC (Control) 30o, 36o and 40o where the tea leaves were fermented initially for 45-50 minutes at an private factory. During this oxidation process, withered and rolled leaf looses its green colour acquiring copper red to brown colour. Drying terminates these biochemical changes and remove moisture thereby the colour of fermented leaves turns from copper red to black and fermentation is arrested. Total polyphenols content were determined colorimetrically using Folin-Ciocalteau method and caffeine was isolated from all the samples by Liquid-Liquid extraction using chloroform. The results showed that increase in fermentation temperature significantly increases caffeine content whereas polyphenols content showed a great reduction at 30o, 36o and 40o. However further studies are needed to evaluate the organoleptic characters such as taste and aroma.

Trupti Pednekar, Subash.S. Pillai, A. R. Shabaraya, Mohd Azharuddin

Olmesartan medoxomil is an angiotensin II antagonist used as an antihypertensive drug which has poor oral bioavailability. Hence, an attempt was made to prepare and evaluate mucoadhesive buccal films containing Olmesartan medoxomil as model drug. Various mucoadhesive buccal films were prepared by employing HPMC alone, and in combination with Eudragit RL100, Carbapol 934, Ethyl cellulose were prepared by solvent casting method using ethanol , water and acetone as solvents, tween 80 as solubilising agent and glycerine as plasticizer. The prepared mucoadhesive buccal films were evaluated for their physic-chemical parameters such as thickness uniformity, weight uniformity, folding endurance, drug content , surface pH, swelling index, bioadhesion, percentage moisture loss and uptake, vapor transmission rate. The formulations exhibited good results. In – vitro drug release studies were conducted for OLM loaded films in phosphate buffer (pH 6.8) solution. The drug release was in the range of 67 to 90 % in 6hrs.. Stability studies were carried out with selected formulation. In- vivo release was evaluated in rabbits by patch test and it showed good correlation with the in-vitro release data. Drug release was found to be diffusion following zero order as per kinetic studies.

Synthesis and Antimicrobial Activity of Some Novel Schiff Bases and 4-Thiazolidinones Containing N-Benzyl Piperidine Moiety

Chandra Kant Belwal, Kaushik A. Joshi

A series of novel schiff bases containing N-benzyl piperidine moiety (1a-d) were synthesized by the reaction of N-benzylpiperidine-4-carbaldehyde with suitable aromatic amines. And synthesized schiff bases were converted to a series of novel 4-thiazolidinones (2a-d) by the reaction of Schiff base with mercaptoacetic acid. The chemical structures of the synthesized compounds were confirmed by using spectroscopic and chemical analysis techniques. All the above compounds were screened for their antimicrobial activity against some selected pathogenic microorganism. Good level of antimicrobial activity has been displayed by both categories of compounds against tested pathogenic microorganism. Thiazolidinone derivatives (2a-d) showed higher activity than schiff base derivatives (1a-d).

Development and Validation of LC Method for Determination of the Enantiomeric Purity of Silodosin in Bulk Drug Substances

Shaik Jafer Vali, Santhi kumar Saladi, Shakil S Sait, Lovleen Kumar Garg

A simple, rapid, novel and normal phase chiral HPLC method has been developed for the separation of S-Silodosin from R-Silodosin and quantitative determination of S-Silodosin enantiomer in Silodosin bulk drugs. The proposed method was based on normal phase chromatographic separation on Polysaccharide-Based Chiral Stationary Phase, Chiral pak AS-H column (250mm ×4.6mm i.d.; particle size,5µ) at a temperature of 28°C using a mobile phase consisting of n-Hexane, Ethanol and Diethyl amine (600 : 400 : 0.1 v/v/v) at a flow rate of 1mL.min-1 with an injection volume of 10μL. Quantitation was achieved with UV detection at 270 nm based on peak area with linear calibration curves. The elution times of S-Silodosin and R-Silodosin were 5.0 min and 6.0 min respectively. In this proposed chiral HPLC method, the resolution between S-Silodosin and R-Silodosin was found to be greater than 1.5. The developed method was validated with respect to linearity, accuracy, precision, solution stability, ruggedness, robustness, limit of detection and limit of quantification. The recovery obtained for S-isomer was in between 102.2 % and 104.4%. The detection limit obtained for S-isomer was 0.04µg.mL-1 and the quantification limit was 0.13µg.mL-1 respectively. Linearity was performed for the S-isomer from LOQ to 150%. The correlation coefficient obtained for S-isomer was more than 0.999. The solution stability of Silodosin bulk drug was determined and the compound was found to be stable up to 48 hrs. As the method has less run time (10 min), it can be useful in quality control laboratories for routine analysis. Key words: R-Silodosin, S-Silodosin, Polysaccharide-based chiral stationary phase, High performance liquid chromatography and Method validation.

Melasma is a cosmetic problem that sometimes cause great emotional suffering. One survey showed that melasma was associated with a significant impact on health related quality of life. It is defined as a disorder of pigment metabolism characterized by sharply demarcated, blotchy, brown maculae, usually symmetrical on the cheeks, forehead, sometimes on the upper lip and neck. In Unani Medicine, it is mentioned that Kalf is due to black bile homour and charred blood parts, which oozes out of capillaries and get accumulated under the skin. The present study was a Randomized, parallel group, comparative clinical trial. The present research was done to evaluate and to compare the clinical efficacy of a topical application made up of powdered cuttlefish bone and lemon juice along with oral Cascuta reflexa capsule which was compared with another group that is oral placebo with same topical application. The efficacy of the treatment was evaluated by MASI, skin color shades chart, Patient’s Global Assessment, Patient’s Satisfaction Index and DLQI. Assessment of safety was done by clinical assessment, patients’ complains about any adverse effects i.e. itching, inflammation, rashes, eruptions etc., DLQI and laboratory parameters such as LFT, KFT, CBC and Hb%. At the end of the treatment all the efficacy parameters showed significant improvement when compared with baseline in both the groups; however the difference between the groups was not statistically significant. Thus, topical application had promising effects in melasma. Key words- Kalf, Unani formulation, hyper pigmentation, MASI, cuttlefish bone

Formulation Development and Characterization of Sustained Release Matrix Tablets of Doxofylline

Kaushik P, S Jain, S Sardana

The objective of this research work was to prepare sustained release matrix tablets of doxofylline. Doxofylline is a xanthine bronchodilator having reduced affinity for A1 & A2 adenosine receptors. Different grades of hydrophilic polymers( HPMC K4M, HPMC K15 cps, HPMC K100 M, Sodium carboxymethylcellulose) and hydrophobic polymer (ethyl cellulose) were used. FTIR study shows that drug and other excipients are compatible with each other. Tablets were prepared by wet granulation technique using non-aqueous solvent IPA and PVP K90D as a binder. Under stage I of preliminary study, tablets were formulated using polymers alone. In stage II polymers were used in combination, with an objective of sustaining release up to 12 hrs. The effect polymer concentration on drug release profile was investigated. The amounts of HPMC K100 M & NaCMC were selected as independent variables. The results of final batches indicated that a low concentration of HPMC K100 M & high amount of Sodium CMC favours sustained release of doxofylline from matrix tablets. Accelerated stability study for 8 weeks confirmed that the best selected formulation F 15 was stable

Mahesh Nasare, Satish. J, Manikanta Kumar. A, M. Akiful Haque, V.V.L.N.Prasad, Prakash.V. Diwan

A simple, rapid and specific UV spectrophotometric method with good sensitivity was developed and validated for the simultaneous determination of tamsulosin and finasteride in bulk and pharmaceutical formulations. In methanol, the lambda max of finasteride and tamsulosin was fixed as 235 and 225nm respectively, using a Shimadzu UV–Visible spectrophotometer (model UV-1800) with quartz cells. In this proposed method both these drugs obeyed linearity individually and in mixture within the concentration range of 1- 10 μg ml-1 for tamsulosin and 12.5 - 100 μg ml-1 for finasteride, with a correlation coefficient value of 0.9992 and 0.9994 for tamsulosin and finasteride respectively. The low relative standard deviation values indicate good precision and high recovery values indicate accuracy of the proposed method. The proposed method had been applied to the determination of drugs in commercial formulations. Assay results were in good agreement with label claim. The method was validated according to the ICH guidelines.

Formulation and Development of Floating Tablet of Highly Water Soluble Drug Using Combination of Hydrophilic and Hydrophobic Polymers

EK Patel, Meghana Lande, VV Potanis, RV Antre, RJ Oswal

Water soluble drugs if not formulated properly, may release the drug at a faster rate and produce a toxic concentration on administration. Captopril belongs to the class I of biopharmaceutical classification system (BCS) has short half life (~2hrs) shows dose dumping, burst and stability in acidic pH of stomach. In this study HPMC K15M and Compritol 888 ATO alone and in combination different proportions using physical mixture and solid dispersion method to prepare floating matrix tablet. The tablets were evaluated for appearance, weight variation, hardness, friability, floating lag time, duration and integrity of matrices, In-vitro and In vivo drug release kinetics. IR spectra, thermal behavior and X-ray diffraction pattern of selected solid dispersions were carried out indicating no degradative changes. The rate of release of Captopril from floating matrix tablets containing physical mixtures was found to be affected by the concentration of Compritol 888 ATO increase in the concentration decrease the release. Among the formulations containing solid dispersions of drug with Compritol888 ATO (SPC3c’’) give retardation of drug release (t90% >12) for extended time. All formulations indicated diffusion exponent (n) values in the range 0.4 to 0.6 suggesting Fickian diffusion. The values of ‘n’ increased with increase in concentration of lipid polymers suggesting a shift in the mechanism of drug release from Fickian to anomalous. All formulations show initial burst release which may due to high water solubility of Captopril. The X-Ray photographs indicated the residence of tablet in stomach for about 5hs.

Spectrophotometric Estimation of Tolperisone Hydrochloride and Diclofenac Sodium In Synthetic Mixture by Q-Absorbance Ratio Method

Satish A. Patel, Kaushik P. Hariyani

The present manuscript describes simple, sensitive, rapid, accurate, precise and economical Q-absorbance ratio method for the simultaneous determination of diclofenac sodium and tolperisone hydrochloride in bulk and synthetic mixture. Absorbance ratio method uses the ratio of absorbances at two selected wavelengths, one which is an isoabsorptive point and other being the λ-max of one of the two components. Tolperisone hydrochloride and diclofenac sodium show an isoabsorptive point at 267 nm in methanol. The second wavelength used is 255 nm, which is the λ-max of tolperisone hydrochloride in methanol. The linearity was obtained in the concentration range of 2-20 μg/ml for both tolperisone hydrochloride and diclofenac sodium. The concentrations of the drugs were determined by using ratio of absorbances at isoabsorptive point and at the λ-max of tolperisone hydrochloride. The method was successfully applied to pharmaceutical dosage form because no interference from the synthetic mixture excipients was found. The suitability of this method for the quantitative determination of tolperisone hydrochloride and diclofenac sodium was proved by validation. The proposed method was found to be simple and sensitive for the routine quality control application of tolperisone hydrochloride and diclofenac sodium in synthetic mixture or pharmaceutical dosage form. The results of analysis have been validated statistically and by recovery studies.
