Impact of Process Parameters on Particle Size Involved in Media Milling Technique Used for Preparing Clotrimazole Nanocrystals for the Management of Cutaneous Candidiasis. AAPS PharmSciTech. 2019 Apr 26;20(5):175 Authors: Patel V, Sharma OP, Mehta TA Abstract Clotrimazole is widely used for the management of cutaneous candidiasis infection. The low solubility of clotrimazole and excipient-related topical side effects (of currently available marketed products) cause the compromised efficacy of the therapy with poor patient compliance. In the present investigation, a clotrimazole nanocrystal-based nanogel was developed. Clotrimazole nanocrystals were optimized with studying the impact of individual process parameters of the media milling technique. The optimum level of individual process parameters was considered in the development of optimized batches. A promising result was obtained with a non-ionic stabilizer, polysorbate 80, at a concentration of 1.5%w/v, showing a distinct reduction in the particle size from above 31 μm to 264 nm and a polydispersity index of 0.211 with media milling at 1500 rpm for 6 h. This result was found to be in concordance with the TEM images, revealing a sharp diminution in particle morphology. Powder X-ray diffraction and differential scanning calorimetry results revealed crystallinity of clotrimazole (CTZ) in nanocrystal form. The optimized nanocrystal suspension was formulated into nanogel with car...
