Prunus amygdalus Batsch (Family - Rosaceae) is widely used in traditional system of medicine to treat diabetes in India. The ethanolic extract (250 & 500 mg/kg) of leaf, flower and seed were taken up undertaken to evaluate the antidiabetic activity against normal and streptozotocin induced diabetic mice. Oral administration of extract for 21 days resulted in significant reduction in blood glucose level. Chronic effect of the extract on serum biochemistry were also studied and it was found that serum cholesterol, triglyceride, creatinine, urea, alkaline phosphatase levels were decreased significantly by all the extracts and Glibenclamide but HDL levels and total proteins were found to be increased after treatment. Thus, this studies shows that P. amygdalus has antidiabetic action and the extract should further be subjected to bioactivity guided drug discovery to isolate a lead compound responsible for this activity. © 2010 RJPBCS.

Objective: Nicorandil is a vasodilatory drug used to treat angina. Nicorandil has oral bioavailability (70%) and half-life 1 hr. It is administered through the buccal mucosa enters directly in the systemic circulation, thereby minimizing the first pass hepatic metabolism and adverse gastro-intestinal effects. Therefore, the present investigation is concerned with the development of the buccal tablets. Methods: The present work was performed to develop and evaluate buccal tablet containing anti-diabetic drug (nicorandil). Ethyl cellulose was used as backing membrane and carbopol 934p and hydroxypropyl methyl cellulose K100M was used as bucco adhesive polymer. Aspartame was used as a sweetener. Thickness, hardness, weight variation and drug uniformity were investigated. Results: The tablet formulations were also subjected to drug release in 250 ml 6.8 phosphate buffer. Ex vivo bioadhesion, retention time and permeation through porcine buccal mucosa membrane. F5 formulations showed maximum amounts of drugs release (89.24%) at the end of 10 hrs dissolution study. F5 also showed maximum bioadhesion (0.0791 N) and the resident time of F5 formulation was 9.5 hrs. It shows 49.32% drug release after 10 hrs permeation study through porcine buccal mucosa mounted in Franz cell. Conclusion: The results of the study suggested that new buccal tablet formulations of combined bucco adhesive polymers can be suitably developed as an alternate to conventional dosage forms. © 2015, Asian Journal of Pharmaceutical and Clinical Research.

The objective of present study was to formulate hydrogel thickened Lornoxicam transdermal formulation. Eutectic mixture of camphor and menthol was chosen as oily phase (maximum 10%), solvent for Lornoxicam and powerful penetration enhancer. Tween 80, ethanol and Carbopol 934p, HPMC K-15M and Xanthan gum were selected as surfactant, co-surfactant and hydrogel thickening agent respectively. Ternary phase diagrams were constructed to obtain the concentration range of oil phase, surfactant and co-surfactant for microemulsion formulation. Hydrogel thickened microemulsions were characterized for pH, viscosity, spreadability, in vitro drug transport study with excised rat skins and invivo anti inflammatory activity. The average drug transport rate of optimized hydrogel thickened microemulsion containing 1 % w/w Lornoxicam, 10 % w/w oily phase of camphor and menthol, 30 % w/w tween 80, ethanol (2:1), 57 % w/w water, 1.5 % w/w Carbopol 934p and 0.5 % w/w Triethanolamine through rat skin was 2.02 μg/cm2/h . The percentage in vitro drug release of optimized hydrogel thickened microemulsion was 78.91 %. pH, viscosity and spreadability of optimizes batch was 6.4, 5291 cps and 5.98 gcm/sec. © 2014 Biswajit Biswal et al.
