Development and Evaluation of Flupirtine Maleate Transdermal Patch Containing Different Permeation Enhancers

Rehab Tonse, Amit Patil, Smitha Shetty

The present study was aimed at the formulation of transdermal patches of flupirtine maleate containing different permeation enhancers. It acts indirectly as N-methyl-D-aspartate (NMDA) receptor antagonist and activates the K+ channels; thereby acts as a skeletal muscle relaxant. Flupirtine maleate transdermal patches are intended to provide localized effect. The patches were prepared by solvent evaporation technique, using polyvinyl alcohol (PVA) as the polymer whereas dimethyl sulfoxide (DMSO) and polyethylene glycol (PEG-400) as the permeation enhancers. Methanol was used as a solvent to dissolve the drug and glycerol was used as the plasticizer. These patches were evaluated for in vitro permeation, tensile strength, percent moisture absorption, drug content uniformity, film thickness, weight variation and folding endurance. All the patches showed extended release properties. Formulation FDD8 containing 8% polymer and 2% DMSO was found to be the optimized formulation on the basis of evaluation parameters. In vitro permeation release was found to be 95.71 ± 0.01% at the end of 12 h. As the concentration of DMSO increased, the release profile of drug was enhanced. This indicated that DMSO improved the release profile of flupirtine maleate when compared to PEG-400. The release kinetics of the transdermal patches followed Higuchi matrix model. The stability studies showed that all the optimized patches were stable during their study period. From the present study, it can be concluded that addition of DMSO yields good result to enhance the permeation of the drug.

Bhambar Kunal V, Pande Shrikant D, Bhambar Rajendra S, Gadakh Pravin P

Methimazole is active pharmaceutical ingredient effectively utilized in hyperthyroidism. Methimazole inhibits peroxidase as well as iodine interactions with thyroglobulin to produce triiodothyronine with thyroxine. Methimazole shows very low protein binding (1-10%) bounds to plasma proteins and easily metabolized by liver. In this investigation, efforts given to develop a sustained release matrix tablet of Methimazole. Sustained release drug delivery systems are for a maximum of 24 hours clinical effectiveness. Such systems are primarily for the drugs of short elimination half-life. However, drugs with long half-life also qualify if a reduction in steady state fluctuation is desired. Matrix tablets of methimazole were prepared by utilizing direct compression method. HPMC along with Sodium carboxy methyl cellulose used to retard drug release from the dosage form. Matrix tablets of methimazole were evaluated for different quality control test to improve quality of the product. In vitro release study of methimazole matrix tablets shows that polymer percentage used in the formula is enough to extend the release of the drug for at least 12 hr. In dissolution study of matrix of methimazole formulation F2 shows maximum drug release 97.93 % at the end of 6 hours while F1 shows least 83.64 %.

Development and Evaluation of Indomethacin Parenteral Delivery of Microspheres for the Treatment of Gout

Namratha Shettigar, Rehab Tonse

Gout is a disease caused by the deposition of monosodium urate (MSU) crystals in tissue such as cartilage, synovial membranes, bones and skin which causes inflammation in the synovial tissue. Indomethacin is first line of drug used as NSAID for the treatment of Gout. The aim of this study was to encapsulate Indomethacin in ethyl cellulose microspheres and compare the efficiency of the formulated Indomethacin microspheres with the Marketed formulation. Indomethacin microspheres were prepared by solvent evaporation method. FTIR  studies revealed there was no significant interaction between the drug and polymer. Preformulation studies gave satisfactory results. SEM studies showed a spherical smooth microsphere average size of 10.4±3.04. The percentage entrapment efficiency and percentage drug release after 10 hours was found to be 82.97±1.6 % and 52.04±0.58 % respectively. The therapeutic effect of the Indomethacin microspheres was evaluated by the swelling of knee joints, joint range of motion and histologic analysis of MSU induced rat model. The prepared indomethacin microspheres showed effective prolong in the retention time of the drug in the intra articular cavity to 30 d which is more than that of the marketed formulation. Intra- articular injection of Indomethacin microspheres efficiently relieved inflammatory symptoms such as swelling index, joint range motion and suppressed inflammatory cell infiltration than the marketed formulation. Thus intra-articular injection of Indomethacin loaded microspheres proved to be a promising therapeutic method in the treatment of Gout.

The objective of this research work was to carry out design and evaluation of sustained release matrix tablets of Itopride by use of natural and synthetic polymers.  Matrix tablets were prepared by wet granulation technique by using natural polymers like Carbopol 934, Tamarind poly saccharide, Locust bean gum, Ethyl cellulose, HPMC K 100 as matrix forming agent and excipients such as Lactose, Starch 1500, Magnesium stearate, MCC and talc were used. The dissolution medium consisted of 900 ml of 0.1 N HCl for first 2 hours and then 7.4 phosphate buffer for remaining 10 hours. The release of Itopride from matrix containing lactose, micro crystalline cellulose and starch 1500 as diluents. The drug release rate was found in order of lactose> micro crystalline cellulose>starch 1500. The formulation was optimized on the basis of acceptable tablet properties and in-vitro drug release. The release data were fit into different kinetic models (zero-order, first-order, Higuchi’s equation and Korsmeyer-Peppas equation). Optimized formulation was tested for their compatibility with Itopride by FT-IR studies, which revealed that there is no chemical interaction occurred with polymer and other excipients. The drug release profile of the best formulation was well controlled and uniform throughout the dissolution studies.

Study the effect of Dipeptidyl Peptidase 4 Inhibitors as an Antidiabetic in Type 2 Diabetes Mellitus (T2DM)

Anil K.Yadav, Pranay Wal, Priyanka Verma

Dipeptidyl peptidase IV is a key regulator of insulin- stimulating hormones, glucagon-like peptide and glucose dependent insulinotrophic polypeptide. Thus it is a promising target for treatment of type 2 Diabetes mellitus. Inhibition of plasma Dipeptidyl peptidase IV enzyme lead to enhanced endogenous glucagon like peptide-1, GIP activity which ultimately results in the potentiating of insulin secretion by pancreatic cell and subsequent lowering blood glucose level, HbA [1c], glucose secretion, liver glucose production. One of the principal goals of diabetes management is to attain haemoglobin HbA [1c] treatment goals and prevent the onset or decrease the rate of occurrence of Microvascular conditions.2, 6 numerous treatment options are available for management of Type 2 Diabetes mellitus, various class of DPP IV inhibitor being explored such as Sitagliptin and Vildagliptin successfully launched. Several other novel DPP IV inhibitors are in pipeline, Unless there are clear contraindications, metformin monotherapy is prescribed, and if HbA [1c] targets are not attained after 3 months, 1 of several classes of agents could be added, such as sulfonylurea’s, Thiazolidinediones, dipeptidyl peptidase-4 inhibitors, - glucagon like peptide-1 receptor agonists, or basal insulin.2,6 Despite the broad range of therapeutic options, the attainment of HbA [1c] goals among patients with diabetes remains challenging, with just slightly more than half (52%) of diabetes patients attaining the common HbA [1c] goal of < 7.0%. The present review summarizes latest preclinical and clinical trial data of different DPP IV inhibitors with a special emphasis on their DPP8/9 fold selectivity and therapeutic advantages over GLP-1 based approach. Keywords: Diabetes 2, Dipeptidyl Peptidase-4, glucose-dependent insulinotrophic polypeptide, glucagon-like peptide-1.
