Abstract
Objectives: The objectives of this study were to prepare the mucoadhesive mucoadhesive gastroretentive drug delivery system of alginate beads containing turmeric extract and to evaluate its anti-gastric effect.Methods: Turmeric extract was made by macerating turmeric powder in ethanol 96% and evaporated using rotary evaporator at 50°C to obtained concentrated extract. Then, it was prepared alginate beads containing 5% turmeric extract by gelation method. The mucoadhesive properties of alginate beads containing turmeric extract were tested in vitro in male rats and the anti-gastric ulcer effect was tested on HCl-induced gastric ulcer in rats.Results: The mean diameter of alginate beads obtained was 1.13±0.19 mm. Bioadhesion test showed that alginate beads containing turmeric extract could be attached on gastric rats mucosa. Anti-gastric ulcer test showed that the healing of gastric lesions in rats was faster using alginate beads containing turmeric extract compared to untreated ones.Conclusions: The results of this study suggest that mucoadhesive drug delivery systems of alginate beads containing turmeric extract are potentially developed as an anti-gastric ulcer.
