Resumo Inglês:
In this work a different type of formulation, as disc, containing a selected mucoadhesive polymer, fillers, and
binders were investigated for their potential as a mucoadhesive gastroretentive delivery system to deliver famotidine
in the stomach. Various types of hydrophilic diluents were evaluated for their swelling and mucoadhesive property
and one (polyvinylpyrrolidone, PVP) was selected to combine with the selected mucoadhesive polymer (polyethylene
oxide, PEO). Discs with different ratios of PEO and PVP were prepared and evaluated for swelling, dissolution,
and mucoadhesion. The swelling property of the discs increased as the concentration of PEO was increased and
also did the mucoadhesion. These discs retained their integrity and adherence onto gastric mucosa for more than 10
h under in-vitro conditions. The PEO, in combination with PVP, yielded a non-disintegrating type mucoadhesive
dosage form which was suitable for gastroretentive applications to achieve the desired release profile of the drug.
