ABSTRACT
This work was aimed at masking the bitter taste of ondansetron HCl
using Ionotropic gelation technique. Ondansetron HCl is 5HT3 receptor
antagonist commonly used in treatment of emesis. Oral adminstration
of ondansetron HCl faces major problem due to its bitter taste. In this
work taste masking was done by formulating tasteless beads of
ondansetron HCl using varied concentration of xyloglucan polymer by
ionic orifice gelation technique. beads were evaluated for various
parameter like drug content, particle size, entrapment efficiency, in
vitro taste evaluation and drug release. Use of 3% polymer
concentration shows 98 % practical yield of beads having 90.60 %
entrapment efficiency, particle size 630 μm. SEM study reveals spherical shape with rough
surface of beads, in vitro taste evaluation of beads shows that satisfactory taste masking was
achieved. Drug release from beads was found to be 84.34 % within 20 min. These beads were
compressed into fast disintegrating tablet which rapidly disintegrated in oral cavity.
Crospovidone was used as a superdisintegrant. 4 batches of tablets were prepared by varying
concentration of crospovidone from 2-5 %.tablets were subsequently evaluated for various
pharmacopoeial tests, drug release and disintegration time. The results were found to be
