In Vitro and In Vivo Evaluation of DMSO and Azone as Penetration Enhancers for Cutaneous Application of Celecoxib.

Background: Celecoxib (CXB) has been explored as an anti-inflammatory or chemopreventive drug for topical treatment of skin diseases and cancer.

Objective: The main aim of this work was to investigate the potential of dimethylsufoxide (DMSO) and Azone (AZ) as penetration enhancers (P.Es) for topical delivery of CXB.
