Formulation and Evaluation of Niosomal gel using Tretinoin and Clindamycin combination

The objective of the present study was to formulate topical Niosomal gel loaded with combination of Tretinoin, also known as all-trans retinoic acid (ATRA), and Clindamycin for the beneficial of acne patients, to provide sustained release effects, to prevent their side effects. Purpose of this study was to develop a stable formulation that allows progressive follicle penetration and increased efficacy. Niosomes was prepared by ether injection method. Preformulation studies such as melting point, FTIR spectroscopy, UV spectroscopy, solubility, partition coefficient (log P) were performed for both drugs. In preformulation study, FTIR spectrum reveals that drugs were in pure state. Combination of Tretinoin and clindamycin reveal better therapeutic efficacy and patient compliance as compared to individual agent. From the research findings, it can be concluded that Tretinoin as well as Clindamycin hydrochloride was successfully integrated into niosomal gel by ether injection method for topical application in the treatment of acne.
