ABSTRACT
Objectives: The specific objective of the study is to formulate and
evaluate the proliposomal gel of Repaglinide for effective transdermal
drug delivery. Method: Proliposomes of Repaglinide were prepared by
thin film hydration technique by using vacuum rotary evaporator and
varying the composition sorbitol, soya lecithin and cholesterol.
Proliposome formulations were characterized for compatibility, vesicle
size, drug content, entrapment efficiency, surface morphology, zeta
potential, in-vitro drug release. The proliposomal gel was prepared for
optimized proliposomal formulation RF3 and RF6 by incorporated into
1%W/V Carbopol gel. The in-vivo skin irritation study and
hypoglycemic activity was carried out for the gel PLG1 and PLG2.
Results: Drug and physical mixture were characterized by FTIR, the
result of IR and study showed that no interaction between drug and polymers and other
formulation parameters of formulated proliposomes and proliposomal gel are evaluated
which showed better results. Conclusion: The drug-excipients compatibility by FT-IR
confirmed no significant interaction between drug and selected excipients. Proliposomal gel
PLG1 and PLG2 were proved nonirritant and more hypoglycemic effect as compared to oral
formulation because it provide reduction in glucose level with controlled manner upto 24 hr.
Hence, proliposomes drug delivery system was better choice for controlled release of drug
through topical drug delivery.
Keywords: Repaglinide, Proliposome, Mannitol, Sorbitol, Soya lecithin, Hypoglycemic, Controlled release.
