The study on the effect of polymer concentration in vitro drug release profile revealed that there is a change parameters (t50, t80, and MDT) with concentration. Fraction HPMC K4M, K 100 M, Ethyl Cellulose were required to be 15, 10, 7 mg respectively for designing optimized batch F7. rate Colchicine decreased proportionally an increase ethyl K100 M. Also high amount K4M leads less initial sust...

The objective of this study was to evaluate the pharmacokinetic and pharmacodynamic properties of furosemide following gastroretentive dosage from (GRDF) administration. A furosemide (60 mg) GRDF, releasing the drug during 6 hours in vitro, or an immediate-release tablet was administered to healthy male volunteers (N = 14) in a crossover design. Food and liquid intake were standardized; urine w...
