Gastro-retentive
drug

are
vital
for
enhancing
bioavailability
and

time,
especially
drugs
with
a
short
half-life
like
Ondansetron
HCl.
This
study
developed
raft-forming
gastroretentive
system
using
polyelectrolyte
complex
(PEC)
of
Chitosan
anionic
polymers
to
improve
stomach
retention,
regulate
release,
enhance
therapeutic
efficacy.
Various
formulations
were
optimized
based
on
polymer
type,
ratio,
cross-linking
agent
concentration,
hydroxypropyl
methylcellulose
(HPMC
K100M).
The
best
formulation
(F12:
Chitosan:

showed
high

(11.5%),
buoyancy

confirmed
PEC

stability,
while
FE-SEM
demonstrated
homogeneity.
Drug
followed
non-Fickian

indicating
that
both
