|
Sustained release Aceclofenac matrix tablets constituting Kollidon SR (Polyvinyl acetate- povidone based matrix
retarding polymer) were developed for manifesting desirable release profile. Matrix tablets were prepared by direct
compression of Kollidon SR varying proportion with fixed percentage of aceclofenac. Tablets containing 50 % Kollidon SR
demonstrated a rapid rate of drug release with an initial burst effect. Incorporation of more Kollidon SR in the tablet
prolonged drug release with subsequent minimization of burst effect as confirmed by mean dissolution time, dissolution
efficiency, f2 and drug release kinetic data. The formulation showed close resemblance to commercial product Senafen. The
results were explored and explained by the difference of physico-chemical property and micromeritic characteristics.
Insignificant effect of various factors e.g. pH, ionic strength, paddle speed was found on drug release. The formulation
followed Korsmeyer and peppas kinetic of drug release. Stability study data indicated stable character after short term
stability study.
