Kundan E. Phatangare, Sharada L. Deore, Jyoti S.Vaidya, Leena P. Deore, Devidas G. Bachhav

Novel drug delivery systems are need of recent developments. Controlled drug delivery systems for oral route are widely acceptable and easy to formulate. Oral controlled release systems developed to overcome short comings of conventional controlled released formulations such as short gastric residence time, unpredictable gastric emptying time, unstable at higher pH, site specific absorption, etc. Various approaches have been developed to retain dosage form in stomach for longer period of time. Bioadhesive systems, high density systems, expanding or swelling systems, effervescent buoyant systems has been discovered till date. Drugs those having narrow absorption window in stomach, stable at acidic pH and unstable in the intestinal or colonic pH, having low solubility at higher pH are suitable to develop as buoyant drug delivery systems. Present review focuses on various aspects of buoyant drug delivery systems.

It’s necessary the ports around the world should be measuring their performance and the determination thus indicators considering the importance diminution to achieving a lot of their targets such as to know their situation about competition, strategic planning, update their technology and expansion the investments. Although international organization had submitted them and published also thus indicators but in fact also a lot of them don not following  particular the whole governing ports,  In the world, all ports are unique, and the task of measuring and analyzing performance is not simple and is made more difficult by the failure to establish industry standards on what to measure, how to measure it and how to express the measure in an informative and consistent manner. This difficulty is compounded by the fact that there is no single measure that can sum up all the important aspects of port or terminal performance. This study aims to analyze the existing literature about performance measures of container terminal operations.

Review on: Self Micro-Emulsifying Drug Delivery System

Gade Abhishek V, K.S. Salunkhe, S.R. Chaudhari, Gadge P.B, Dighe G.S, Amit Asati

The oral delivery of lipophilic drugs has a major challenge because of low aqueous solubility of such drugs. Self-microemulsifying drug delivery systems (SMEDDS) have ability to increase solubility and bioavailability of poorly soluble drugs. Self-micro emulsifying drug delivery systems are isotropic mixtures of oil, surfactant, co-surfactant of co-solvents can be used for the design of formulations in order to improve the oral absorption of highly lipophilic drugs. Self micro-emulsifying drug delivery system can be orally administered in hard or soft gelatin capsule and form fine stable emulsion (oil-in-water emulsion) aqueous dilution owing to the gentle agitation of gastrointestinal fluid. Efficiency of oral absorption of the drug from the SMEDDS depends on formulation elated parameters such as concentration of surfactant, co-surfactant, ratio of oil and surfactant, charge and droplet size. Thus, there are few drug products of the pharmaceutical market formulated as SMEDDS confirming the difficulty of formulating hydrophobic drug compounds in to such formulations. The fact that almost 40% of the new drugs are hydrophobic in nature which are studies with SMEDDS will continue and more drug compounds formulated as SMEDDS will reach pharmaceutical market.

Estrogen Receptor a (Esr1) Polymorphism and Breast Cancer

Ritu Yadav, Preeti Chauhan, Vivek Kaushal, Minakshi Vashist

Estrogen receptor alpha (ESR1) belong to the nuclear receptor family of ligand-inducible transcription factors. It involves in both proliferation of breast cancer cells as well as in carcinogenesis. Many studies on polymorphisms suggested its correlation with various aspects of breast cancer. The most studied Polymorphisms are SNPs and microsatellites lying within intron one of estrogen receptor alpha (ESR1) gene. A possible linkage of ER gene found in families of breast cancer patients, suggested that either the ER gene itself or an adjacent gene may be a risk of breast cancer. These alleles have also been found to be associated with traditional risk factors of breast cancer including age, family history, menstrual cycle, menopausal status, anthropometric measurements (height, weight etc.) and pregnancy history. Estrogen receptor alpha (ER-α) status also plays a role in decisions making for endocrine therapy. This review focuses on association of estrogen receptors α (ESR1) polymorphism with the breast cancer risk. By understanding the frequency of occurrence of ER α polymorphism and associated risk factors may elucidate the breast cancer screening, prevention, and treatments strategies in future.

Solid Self Nano-Emulsifying Drug Delivery Sysytem: A Review

Gadge Prashant B, Salunkhe K.S, Chaudhari S.R, Nehe P.T, Gade A. V, Sanjay Harale

Self nanoemulsifying drug delivery (SNEDDS) is used for drugs which exhibit low water solubility. Dissolution is the rate limiting factor for these drugs. SNEDDS are capable of improving the bioavailability substantially of such drugs. They are formulated by utilizing an oil phase, surfactant and a co-surfactant. This formulation forms nano emulsion (O/W type) on contact with aqueous body fluids i.e. gastric juices when administered orally. Solid SNEDDS (s- SNEDDS) can also be formulated in the form of tablet which shows greater advantages. With recent and potential future developments, this technology will continue to enable novel applications in drug delivery and overcome limitations associated with the delivery of poorly water soluble drugs, mainly those belonging to BCS class-II and class-IV.

Advancements in Analysis: Inductively Coupled Plasma- Mass Spectrometry

B. Suman Kumar, B. Pratap, Kranti Sri Mulpuri

The present review provides an overview on recent development and capabilities of inductively coupled plasma mass spectrometry (ICP-MS) technique which allows the determination of elements and isotopes from the biological tissues and related materials with the spatial resolution which typically ranges from 10 to 100 μm. The outstanding properties such as high sensitivity (ranging, ppt–ppq), relative salt tolerance, compound-independent element response and highest quantitation accuracy leads to an unchallenged performance of ICP MS in its efficiency in detection, identification and quantification of trace elements. The elements that are detected are mostly ‘‘trace’’ and can be analyzed from both body tissues and body fluids. The accurate determination of elemental distribution in neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease, etc., helps in the better understanding of the particular diseases. ICP-MS can be applied also in environmental and bioanalytical fields when coupled/combined with different separation techniques for the quantitative determinations.

Medicated Chewing Gum: A Recent Trend of Drug Delivery System

Abhilash Mund, ByomakeshPanda, Shakti Prasad Mund

From the past few decades scientific and technological advancement have been made in the pharmaceutical research and development of oral drug delivery system. Medicated chewing gum (MCG) has drawn attention to the researcher as potential drug delivery system. MCGs are the non-dissolving intraoral dosage form intended for local treatment of diseases of the oral cavity as well as systemic delivery after absorption through buccal mucosa in which the continuation of drug release depends up on masticatory activities. A special in-vitro apparatus was designed and constructed for release testing of MCGs which is official in European Pharmacopoeia. It is an excellent and convenient drug delivery system for self-medication and can be administered discreetly without water. Consequently at present chewing gum is a convenient drug delivery system, which is appropriate for a wide range of active substances. It is very likely that MCGs will be a common drug delivery system and could be a commercial success in imminent future. Purpose of this review article is to discuss the advantage and drawback, methods of preparation, evaluation, and release of drugs, factors affecting release, safety aspects and development with respect to the medicated chewing gums.

Krupa Chaitanyakumar Thula, Pooja Brijeshkumar Patel, Dilip Girishbhai Maheshwari

Medical devices have been become more important in the health care sector. It is mostly used for diagnosis and prevention of public health. There are more than 8000 generic medical device groups, where some medical devices contain drugs. This increases the demand for better regulatory frameworks to ensure that products entering in the market are safe as well as efficient. One of the major issues for companies developing and producing medical devices is to be updated on the bases of regulatory requirements and to implement them in the process. This is particularly true in developing countries, where assessments of health technology are rare and where little regulatory controls exist to prevent the importation or use of substandard devices. So regulation of medical device is a vital need in Pharmaceutical Sector. This article mainly focuses on classification, classification rules, registration procedure, documents required for registration of medical device and fees for application of medical devices in Australia and India. In Australia medical devices are regulated by Therapeutics Good Administration (TGA) whereas in India medical devices are regulated by Central Drugs Standard Control Organization (CDSCO).

Drug-Drug Interactions: How Far It Can Be Prevented?

Partha Pratim Mahata, Abhimanyu Thakur, Shreya Sen Choudhury, Bishal Mishra, Prosenjit Chakraborty, Srijani Chatterjee

Drug-drug interaction is a matter of deep concern as this proves to be the major cause of adverse drug reaction (ADR). It may be on pharmacokinetic or pharmacodynamic level. Pharmacokinetic interactions involve the effect of absorption, distribution, metabolism and excretion whereas pharmacodynamic interactions emphasize mainly on three areas viz.,  interactions that occur at single receptor site, at variety of receptor sites and general non-specific interactions mediated through unspecified sites of action. Different factors are responsible such as genetic constitution, disease, diet, pharmacological response and polypharmacy, age related physiological changes on the basis of the outcomes obtained on the clinical effects of the drug used. This article reflects a clear picture on drug-drug interactions for cytochrome p-450 and non steroidal anti-inflammatory drug (NSAIDs), antihistaminic drugs, antidepressants, interactions with antiretrovirals and Rifampin, anti-anaemic agents, dermatological drugs, antipsychotic drugs, major antibiotics, sedative-hypnotic and anti-cancer drugs.

Examination of Sputum for Detection of Mycobacterium Tuberculosis

Javid Ahmad Bhat, Rajesh Kumar Tenguria

Tuberculosis is one of the main public health problems worldwide. Nearly one-third of the global population, i.e. two billion people, are infected with Mycobacterium tuberculosis and accordingly at risk of developing the disease. More than nine million people develop active TB every year and about two million die. More than 90% of global TB cases and deaths occur in the developing world, where 75% of cases are in the most economically productive age group (15-54 years). At every outpatient clinic, hospitals and health amenities, together in the public and private sectors, all patients have to to be thoroughly screened for cough by health officers manning the health facilities. In addition, within medical colleges and hospitals, in-patients also need to be screened for detection of TB suspects. People with cough for 2 weeks, or more, with or without extra symptoms indicative of TB, should be punctually recognized as pulmonary TB suspects and steps taken to question them to sputum smear microscopy for acid-fast bacilli, for diagnosis of TB.

In vitro Applications of In Silico Designed Antibiofilm Agents for Staphylococcus epidermidis

Aymen F. Al-Mulla, Zahra M. Al-Khafaji

In recent years anti-virulence agents have been used widely to reduce bacterial resistance and prevent damage to host cells and normal flora.  Six  molecules were used in this study (according to previous in silico studies) to detect their antibiofilm activity in lab. Four molecules gave positive results and were as follows : Acetaminophen inhibited biofilm production 100% at 11000µg/ml concentration, Acetylsalicylic Acid inhibition was 100% at 1600µg/ml , Ibuprofen inhibited 35% of biofilm production at 600µg/ml and Acetic Acid inhibition was 25% at 1000 µg/ml concentration .All the molecules at the used concentrations were found to affect biofilm production without significant change in bacterial growth. It was concluded that a structure based drug design strategy using Ligand Based Virtual Screening had a success score of about 60% and that Acetaminophen, Acetylsalicylic Acid, Ibuprofen and Acetic Acid can be used as antibiofilm molecules . Also Non-Steroidal Anti-Inflammatory Drugs family can be a useful library for antibiofilm future investigations.

Gastro-Protective Effect of Ethanolic Extract of Artocarpus Altilis (Breadfruit) on Alcohol Induced Acute Ulcer Model in Albino Wistar Rats

Ajah Austin A, Olorunfemi O Joyce, Onasanwo A. Samuel

The study was designed to investigate the gastro protective effects of fruit extracts of Artocarpus altilis (Breadfruit), using alcohol induced acute ulcer model. The extracts were administered at doses100mg/kg, 200mg/kg and 300mg/kg. 10mg/kg of Omeprazole was used as a reference standard. The parameters used for this were percentage of animals with gastric ulcer (UP), ulcer index (UI) and percentage protection of ulcer (%P). The percentage of animals with ulcer was lowest in both the groups treated with 300mg/kg (16.67 ± 0.004) of extract and those treated with omeprazole (16.67 ± 0.004). While the animals in control group and those treated with 100mg/kg of extract had the highest percentage of animals with ulcer (100.01 ± 0.005). The gastro protective activity was accessed by determining and comparing the ulcer index in the test group with that of the control group. Animals pretreated with Artocarpus altilis extract showed significant reduction in ulcer index in a dose dependent manner when compared to the control group having an ulcer index of 11.51 ± 0.005 when treated 100mg/kg of extract, 3.66 ± 0.004 & 1.83± 0.004 for 200mg/kg & 300mg/kg of extract respectively. The gastro protective effect of 300mg/kg had the same potency as the standard drug Omeprazole. The administration of 100mg/kg, 200mg/kg, 300mg/kg and Standard drug (Omeprazole) reduced Gastric lesions by 9%, 71%, 85.5% and 85.5% respectively. The results suggest that the extract possesses significant protective properties against ulcer in albino rat compared to the control group.

The hepatoprotective activity of the aqueous extracts of S. venulosa (AESV) and S. wallichiana (AESW) leaves on carbon tetrachloride (CCl4)-induced liver damage in albino rats was investigated. Animals were pretreated with the AESV (250 and 500 mg/kg body weight) and AESW (250 and 500 mg/kg body weight) for 15 days and then challenged with CCl4 (1 ml/kg body weight) in olive oil (1:1 v/v) on the 15th day. The degree of protection was measured by using biochemical parameters such as serum glutamate oxalate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), total protein and total bilirubin. Further the effects of both the extracts on catalase (CAT), peroxidase (Px) and superoxide dismutase (SOD) were estimated in both CCl4 treated and extract treated groups. Oral administration of AESV and AESW (500 mg/kg body weight) significantly protected from CCl4-induced elevation in SGOT, SGPT, ALP, total bilirubin, total protein and decrease in the activities of hepatic antioxidant enzymes namely SOD, CAT and Px. The extracts (AESV and AESW at 500 mg/kg body weight) also protected against histopathological damage induced by CCl4 such as distorted hepatocytes and necrosis. The present study suggests that AESV has potent antioxidant and hepatoprotective activity when compared to AESW. Key words: Schefflera species, hepatoprotective, CCl4, antioxidant enzymes.

A Comparative Photostability Study of Flagyrid, Metronidazole and Metrogyl Intravenous Infusion Brands Registered in Sudan

Zuheir Osman, Dhia E.Elhag, Azza H.Suliman, Mohammed Jalal Almansour

Metronidazole 2-(2-methyl-5-nitro-1H-imidazole-1-yl) ethanol is a synthetic nitroimidazole derivative of antibacterial and antiprotozoal activity. It has different dosage forms. The stability of the Metronidazole intravenous of three different brands was studied in order to investigate the kinetics of photodegradation of this drug using a UV/ Vis spectroscopy. The degradation was carried out by the use of short (254 nm) and long UV (352 nm) lamps. The kinetics parameters of reaction order and the rate constants of the degradation were determined for the three brands products.  The degradation process was found to follow first-order kinetics. The present study also reveals that the drug is light-sensitive. Thus, appropriate light protection is recommended during the storage and handling of metronidazole products. The study highlighted the fact that there is a correlation between the radiation intensity and degradation of metronidazole (photodegradation), i.e. as the radiation energy becomes stronger, the degradation rates increases. Furthermore, the rate of degradation was found to follow pseudo-first order reaction. It was also found that as the exposure time of these drugs to radiation increased the degradation was amplified. For all three brands were used in the investigation, the average rate of degradation when using long UV irradiation, and short UV radiation as stress factors were found to be,-0.0061 day-1 and -0.026 day-1 respectively. The obtained results show that UV/vis spectroscopy is satisfactory technique at the determination of metronidazole degradation kinetics in e intravenous products.

N. Siva Ganesh, M. Ratanlal, A. Venkat Narsaiah, K. V. L. D. Spandana, Sridhar Thota, Sagar Narala

The objective of the method was to develop a simple, rapid, efficient, cost effective and reproducible, stability indicating reverse phase high performance liquid chromatography method (RP-HPLC) for the quantification of cinacalcet in bulk and pharmaceutical dosage form. As very few analytical methods have been reported for the analysis of cinacalcet by chromatography, we aimed to develop a method which would be simple with optimum retention time by the use of simple mobile phase, which results in the economic method that can be used for routine analysis of the drug. The RP-HPLC analysis was carried out on Inertsil ODS C18 with a mobile phase of methanol, acetonitrile and water in the ratio of 70:15:15 v/v/v. Detection was carried out at 280 nm using a PDA detector. The method was validated for linearity, accuracy, precision, LOD, LOQ and robustness as per ICH guidelines. The method was found to be linear in the range of 10-50 µg/ml. Limit of detection and limit of quantitation was found to be 0.22 and 0.74 µg/ml respectively. Recovery was found to be in the range 99.7-100.02% and precision less than 1%. The developed method was successfully applied for the estimation of cinacalcet in marketed tablet formulation (PTH 30) and percentage assay was found to be 100.8 %. The developed RP-HPLC method was simple, rapid, accurate, precise and stability indicating for the quantification of cinacalcet in bulk and tablet dosage form.

Apoptosis Induction of Punica Granatum Extract on Human Lung Cancer Cells

J.Sangeetha K.Vijayalakshmi

The present study evaluated the ability of methanolic extract of punica granatum to induce apoptosis in lung cancer cell lines.A549 cells emerged as the most sensitive cell line for in-vitro growth inhibitory activity. A total of 50-60% confluent cells were treated with Punica granatum rind extract and their fraction for 48 hrs in complete growth medium. The ethyl acetate fraction induces uppermost cell death in the A549 cells which indicate the maximum growth inhibition. Ethyl acetate fraction of punica granatum extract induces apoptosis in A549 cells as indicated by nuclear condensation and increased annexin staining. It is possible that the use of punica granatum rind extract as a component in herbal medicines could be justifiable.

Distribution and Limits of Drug Resistance in Gram Negative Bacteria from Hospital Wastewater

Manzar Alam, Mohd Imran

The distribution of resistance to ampicillin, penicillin, erythromycin, tetracycline, and amoxicillin among Gram negative bacteria in the hospital wastewater samples was investigated. The emergence of resistance among the Gram negative bacterial population varied considerably in different drug and water sampling sites. Gram negative bacteria showed lower drug resistant viable count (1.23x104-7.0x102) in site-II (receiving treated wastewater), as compared to more polluted site-I (1.28x104-5.0x102), III (2.22x104-5.0x102) and site-IV (1.63 x104-2.0 x102) respectively. Viable counts of Gram negative bacterial population were recorded higher against erythromycin from sampling site-III. Lower viable counts of Gram negative bacteria were recorded against tetracycline in site-I and IV. Percentage MIC of antibiotic among the isolates observed higher in tetracycline and erythromycin than the other antibiotics. Isolates of Gram negative bacteria showed their tolerance level (MIC) in the range of 2.5-640μg/ml against the antibiotics. Maximum number of isolates exhibited their MICs at lower concentration range 2.5-5μg/ml against tetracycline. A few number of isolates also showed their MIC at lower concentration of other antibiotics tested from all the sampling sites.

Hepatoprotective Effects of Ethanolic Extract of Ipomoea Batatas Leaves on Carbon Tetrachloride Induced Hepatotoxicity in Albino Wistar Rats

Shiva Shanker Rai, Balakrishna, Shivalinge Gowda K.P

In the present study, hepatoprotective effect of an ethanolic extract of Ipomoea batatas leaves, on liver injury induced by carbon tetrachloride (CCl4) was investigated. Wistar albino rats (n=6) were administered 300, 600 and 900 mg/kg body weight extract orally for 10 consecutive days. Marker enzymes SGOT, SGPT, serum protein and Bilirubin (total, direct and indirect) were estimated in serum whereas total protein (TP), Lipid peroxidation (LPO), superoxide dismutase (SOD) and catalase were estimated in liver tissue as markers for oxidative stress.  Histopathological assessment was also done on liver tissue. Ethanolic extract of Ipomoea batatas leaves administration for 10 days prevented the CCl4 induced hepatic injury and oxidative stress. Hepatoprotective effect of I. batatas in CCl4 induced liver poisoning was evident by decrease in elevated levels of SGOT, SGPT and bilirubin. Treatment with I. batatas increased the reduced levels of TP and SOD and decreased the elevated level of MDA concentration and catalase activity in CCl4 induced oxidative stress in the liver. The ability of ethanolic extract of Ipomoea batatas leaves to protect the liver toxicity in rats was further confirmed by histological findings in the liver tissue. In conclusion, it was observed that ethanolic extract of Ipomoea batatas leaves have a dose dependent potential to protect the liver against CCl4induced hepatic injury through its potent antioxidant activity in rats.

Spectroscopic Method for the Determination of Drugs Containing Phenol Group by Using 2, 4- Dinitro Phenylhydrazine

Roopa Kothathi Papanna, Jayanna bidarur Krishne gowda, Padmarajaiah Nagaraja

A spectroscopic method has been proposed for the determination of two phenolic drugs; Phenylephrine hydrochloride and Pyridoxine hydrochloride. The method is based on the oxidation of 2, 4- Dinitro phenylhydrazine and coupling of the oxidized product with drugs to give intensely colored chromogen. Under the proposed optical condition, Beer’s law was obeyed in the concentration range of 2.5 - 30 µg mL-1and 5 – 20 µg mL-1 for Phenylephrine Hydrochloride and Pyridoxine Hydrochloride respectively. The limit of detection (LOD) and limit of quantification (LOQ) were 0.3, 1.95 µg mL-1 and 0.95, 0.64 µg mL-1 in the same order. No interference was observed from common pharmaceutical adjuvants. The suggested method was further applied for the determination of drugs in commercial pharmaceutical dosage forms, which was compared statistically with reference methods by means of t- test and F- test and were found not to differ significantly at 95% confidence level. The procedure is characterized by its simplicity with accuracy and precision.

UGT1A1*28 Polymorphism Related Toxicities are more Frequent in Chemotherapy Naïve Patients

Amany El-Zeiny, Ahmed El Bastawisy, Abeer Bahnasy, Samar Farid

Irinotecan( CPT-11 ) is an important chemotherapy for the treatment of colorectal cancers. The main drawback is its toxicity which includes Neutropenia and Diarrhea.  Some studies confirms the correlation between increasing the incidence of Neutropenia and Diarrhea in patients with UGT1A1*28 polymorphism and other studies could not conclude it. So, other factors may incorporate to act with the presence of the polymorphism to increase CPT-11 toxicity. In this study, we try to find these factors. Patients were divided into 2 groups according to the presence or absence of previous chemotherapy treatment. All patients received standard IFL regimen. Primary endpoint was: comparison between the 2 groups as regard to toxicities. Secondary endpoint was assessment of the incidence of UGT1A1*28 polymorphism. UGT1A1*28 polymorphism was present in 20 patients (43%) of them 15% are homozygous. Twenty three patients were chemotherapy naive in group (1) and 20 patients in group (2) had received previous chemotherapy. Grade (II-IV) neutropenia were found in 52 % of group 1 versus 20 % of group 2 (P=0.1). Grade (II-IV) diarrhea was found in 52 % of patients of group 1 and 15% of patients with group 2 (P=0.05).Treatment delay occurred in 29.16 % of group 1 versus 72.4 % of group 2. (P=0.1). The study concluded that UGT1A1*28 polymorphism is present frequently (43%) in a Caucasian population and is associated with more incidence of toxicity in chemotherapy naïve patients.

Gum odina, a natural polymer of carbohydrate moiety, has already been shown its potential as pharmaceutical excipient as a binder in tablet dosage form and also as an emulsifying agent but very little data are available regarding the use of it as controlled release polymer. In the present study the objective was to investigate the potential use of gum odina as natural release retarding material in sustained release drug delivery system (matrix tablet) using tramadol hydrochloride as a model drug. Tablet containing tramadol hydrochloride was prepared using gum odina and further coated with Eudragit L 100 to prevent its release in stomach. The prepared tablets were evaluated for physical characterization and in-vitro drug release. The results of this study has proven the suitability of using gum odina as an alternative to existing natural polymer in the field of controlled delivery of drug with a significant effect on drug release and desired release rate of drug from tablets.

Simultaneous Estimation of Aspirin and Lansoprazole in Synthetic Mixture by Q-Absorption Ratio Method And dual Wavelength Method

Krupa Chaitanyakumar Thula, Foram Jaysukhlal Chodvadiya, Dilip Girishbhai Maheshwari

Simple, rapid, accurate, precise and economical UV-spectrophotometric methods have been developed and validated for simultaneous estimation of Aspirin and Lansoprazole in a Synthetic mixture. The first method is the Q-Absorption ratio method, which involves formation of Q-absorption equation at 299.2 nm (isoabsorptive point) for Aspirin and Lansoprazole  and also at 276.6 nm (λmax of Aspirin). The Second method is Dual Wavelength Method. The method was based on determination of Aspirin at the absorbance difference between 272.28 nm and 286.41 nm and Lansoprazole at the absorbance difference between 269.20 nm and 294 nm. Developed methods were validated according to ICH Q2 (R1) guidelines. The methods were found to be linear between the range of 33.3-166.6 µg/ml for Aspirin and 5-25µg/ml for Lansoprazole for both methods. The precision (intra-day, inter-day) of methods were found within limits (RSD

A Novel Bioinformatics Approach: to Design Novel 1, 4-Benzothiazine Derivatives for the Treatment of Hypertension

Amit Rai, Vinit Raj, Deepak Kumar

Angiotensin I-converting enzyme (ACE) is a key therapeutic target for combating hypertension and related cardiovascular diseases. ACE inhibitory novel designed substituted 1, 4-benzothiazine derivatives offer the prospect of enhanced potency, high specificity, and no or low side effect. Novel 1,4-benzothiazine derivatives were designed keeping in view the structural requirement of pharmacophore and Quantitatively structure Activity Relationship (QSAR).In the docking study, the most active compounds of the series were, AR 1, AR 2 and AR 3 exhibited good binding properties. Result reveals that the protein-ligand interaction energy of derivatives AR 1, AR 2 and AR 3 were -7.51 kcal/mol, -8.80 kcal/mol and -7.63 kcal/mol, which is slightly greater than the marketed antihypertensive Losartan drug as -5.51 kcal/mol, so that the derivatives have satisfactory affinity with established hypertensive receptor namely Angiotensin converted enzyme II. A computational study was also carried out including prediction of pharmacokinetic properties, toxicity and bioactivity studies. The percentage of absorption (%ABS) was calculated and observed that all titled compounds exhibited a better %ABS %ABS ranging 90.54, 91.42 and 90.55 respectively and compared than standard Losartan drug as %ABS 77.06.Although other pharmacological parameters were better than the standard drug. The above observation suggested that these compounds would serve as better lead compound for antihypertensive screening for future drug design perspective.

Comparative Analysis of Medicinal Properties of Different Condiments Daily Used in Indian Food

Debasish Sahoo, Jikasmita Dalei, M.Rukmini, Ravitosh Ray

The hot continuous extraction (Soxhlet extraction) was carried by using different solvents from daily used condiments such as garlic, ginger, turmeric, cinnamon and clove. Those extracts were qualitatively screened for the presence of the secondary metabolites by standardized method. The extracts were quantitatively analyzed for the presence of Flavonoids and Phenolic compounds where the highest concentration of both the compounds were 432.19* and 395.04^ respectively in 70% ethanolic (v/v) extract of clove. Likewise the antioxidant activity of the acetonic extract of garlic 60.58 ± 1.596% of scavenging effect was the highest whereas succeeding highest extract for the activity was for the 95% ethanolic extract of Turmeric with 59.93±1.600% of scavenging effect. There was a trend of relatedness for the concentration of Flavonoids and Phenolic compound with the antioxidant activity. The extracts from cinnamon, clove and turmeric gave a good anti-microbial property against pathogenic bacteria and fungus. In turmeric crude we get 3 bands this shows there are 2 secondary metabolite in it but in purified sample we get 3 band as we use petroleum ether instead of hexane in purified sample so it may be the reason that as petroleum ether is slightly polar it break curcuminoid into curcumin, demethoxycurcumin and bis-demethoxycurcumin. “Out of all samples analyzed,  it was confirmed that turmeric, cinnamon and clove have the higher potential for  antimicrobial property followed by garlic and ginger.” (*- equivalent to mM quercetin; ^- equivalent to mM Gallic acid).

Assessment of Sleep Quality among Hypnotic Users in Geriatric Population – A Prospective Observational Study

Subeesh K V, Shivashankar V, Gouri N, S sriram, Seema S, Mamatha K

Geriatrics accounts for 7% of the total world population. As age advances apartfrom health, sleep quality also becomes compromised in geriatrics. In addition, an increased incidenceof insomnia has been noted in the elderly. As a result geriatric population constitutes the largestconsumers of hypnotics. The aim of the study was to assess the effectiveness of hypnotics prescribedfor insomnia in the geriatric population. A prospective study for a period of ten months wascarried out in the geriatric population who consumed at least one hypnotic during their hospital stay. A total of 93 patients were included in the study. Data was collected from the patient's case report forms.The sleep quality was assessed using Pittsburgh Sleep Quality Index and the patients were categorizedbased on their PSQI score. A total of 93 patients who met the inclusion criteria were includedin the study. Among them 49(53%) were female and 44(47%) were male. 59(63%) patients of thestudy population were experiencing trouble in falling asleep, 47(51%) were complaining of lessduration of sleep and 43(46.2%) were complaining early morning awakening as their major sleepcomplaint. The analysis of sleep quality by PSQI revealed that a total of 29% (27) patients had scoredless than 5 points (PSQI score) and had good quality sleep and the rest 71% (66) patients were foundto have poor quality of sleep. Zolpidem was found to be most effective for providing fast onset of sleep,diazepam for duration of sleep and clonazepam to reduce the early morning awakening. A statisticallysignificant improvement of sleep quality was observed in alprazolam 0.5mg and 0.25mg with a p-valueof 0.001 and 0.002 respectively.

Formulation and Development of Environmentally Responsive Ophthalmic In-Situ Gel For Brimonidine Tartrate

Dipen R. Bhimani, Dhaval R. Patel

A major problem in ocular therapeutics is the attainment of optimal drug concentration at the site of action, which is compromised mainly due to precorneal loss resulting in only a small fraction of the drug being ocularly absorbed. Brimonidine tartrate is an antiglaucomic agent which shows rapid precorneal exclusion and reduced ocular bioavailability when given in form of conventional ophthalmic formulations. The poor bioavailability and therapeutic response exhibited by conventional ophthalmic solutions may be overcome by the use of in-situ gel forming ophthalmic systems that are instilled as drops into the eye and undergo a sol–gel transition in the cul-de-sac. In the present study, environmentally responsive ophthalmic drug delivery system composed of two gelling polymers with different phase transition mechanisms was developed. Combination of polyacrylic acid (carbopol 934P) and xanthan gum was investigated as ophthalmic vehicle. Different ratios of these polymers were used to prepare environmentally responsive ophthalmic drug delivery system by simple mixing procedure. Developed formulation was assessed for various evaluation parameters such as appearance/clarity, pH, gelation, drug content, rheological measurement, in-vitro release, and sterility testing and stability study. Prepared formulation showed agreeable appearance/clarity, acceptable pH and good gelation property. In-vitro studies demonstrated adequate drug content, desired rheological behaviour and reasonable in-vitro drug release property. Formulation was stable over one month period. In conclusion, the optimum concentration of polymers results in minimized drug loss and sustained drug release. On the basis of these findings, prepared in-situ gel may be considered as a viable alternative to conventional brimonidine tartrate eye drops.
