Abstract

Purpose: To formulate mucoadhesive carbamazepine gel for delivery to the brain via the olfactory mucosa.

Methods: Carbamazepine transfersomes were formulated using Lipoid S 100 and sodium cholate. The transfersomes were evaluated for entrapment efficiency, in vitro release transmission electron microscopy, zeta potential, polydispersity index .The transfersomes were then incorporated into gellan gum gel, and the in situ gel formulation was evaluated for drug content, gel strength, in vitro release and mucoadhesive force. Transfersomes were also evaluated for bioanalytical study in rats.

Result: TEM analysis showed good regular spheres. The negative zeta potential ensures resistance to aggregation. The gel strength of the formulations was in the range of 0.6 to 7.4 g. In vitro diffusion study of transfersomal gel showed Fickian diffusion mechanism. Formulation F6 was optimized depending for gel strength (6.4 g) , drug content (99.47 ± 0.25 %), and good mucoadhesive force (50.24 ± 0.76 dyne/cm2).Bioanalytical study of F6 showed increased drug concentration in brain.

Conclusion: Mucoadhesive carbanmazepine gel can be used effectively to achieve increased concentration of drug in the brain via olfactory mucosal route.
