Formulation Design and Evaluation of Aceclofenac Nanogel for Topical Application

Abstract

Aim: The current study aimed to explore the feasibility of the nanoemulgel for the topical delivery of aceclofenac. Materials & methods: Solubility of drugs in the formulation systems was determined and aceclofenac nanoemulsion (NE) was prepared by high-pressure homogenization technique. Carbopol 940 was added as a gelling agent. Results & conclusion: The composition of optimized NE consist of labrafil along with triacetin as oil, tween 80 and cremophor EL in combination as a surfactant and transcutol HP along with PEG 400 and ethanol as cosurfactant. The droplet size of the NE was 141.1 ± 3.65 nm, with low polydispersity index and negative zeta potential. The aceclofenac–nanoemulgel was developed using carbopol 940 and exhibited excellent permeation in comparison to the marketed sample.
