Formulations of deoxycholic for therapy: a patent review (2011 - 2014).

Introduction: Deoxycholic acid (DOCA) is involved in many physiological functions and has been used in various fields of pharmaceutical formulations as a natural active solubilizing and permeation-enhancing agent. Although DOCA has been suggested to be a promoter of colon cancer, it has also been used extensively as a starting material to obtain new derivatives for potential therapeutic applications.

Area Covered: In this review, we focus on patents and research reports from 2011 to 2014 related to pharmaceutical formulations and therapeutic applications using DOCA and its derivatives as surfactants or absorption enhancers, drug delivery carriers, and anti-cancer agents.

Expert Opinion: In recent few years, DOCA and its derivatives have been used mostly as pharmaceutical excipients for solubilizing lipophilic compounds to improve their bioavailability. Other studies have expanded its applications to include enhanced drug permeability and have designed more effective drug carriers by conjugation with polymeric materials. Recently, a synthetic DOCA injection, ATX-101, has shown long-term efficacy in the non-surgical treatment of unwanted submental fat and acceptable tolerability in humans. Thus, it may be used for reducing specific localized fat accumulations. Additionally, DOCA has been a starting material for anti-cancer drugs, and some derivatives showed strong inhibitory activities against several carcinoma cells.
