Abstract
To developed and prepare a fine Gastroretentive dosage forms
(GRDFs) with fine floating tablets of the combination of the two and
investigate the possibility of those tablets as a delivery system for
controlled release of ondansetron and immediate release of ranitidine.
Gastroretention mode of administration would best achieve the known
pharmacokinetic and pharmacodynamic advantages of CR-DFs of
these drugs. The need for gastro retentive dosage forms (GRDFs) has
led to extensive efforts in both academia and industry towards the
development of such drug delivery systems. Ranitidine is given in
combination with ondansetron A dissolution study shows the release of Ondansetron
Hydrochloride and ranitidine hydrochloride. The Instant layer of ranitidine hydrochloride
release Approx 99.45 percent drug within 15 minutes and control floating layer Ondansetron
Hydrochloride shows release up to 12 Hours Approx 98.23 percent of Drug release in 12
hours. Experiment conclude that Bi-layer tablet is suitable for delivering same drugs with
different release pattern like one layer of drug as immediate release to get quick relief and
second drug as sustained release of drug which gives effect of drug for sufficient long time
and reduce frequency of dose.
