Liposomes, Formulation and Pharmacotechnical Assessment of Anti-Acne Preparations

Abstract

The present study aims at obtaining an efficient local formulation able to ensure both stability and increased penetration of the active ingredients in effective optimal concentrations without side-effects. The novelty of this study is the association in an encapsulated form (liposomes) of tretinoin to benzoyl peroxide as an innovative alternative capable of minimizing side-effects, but preserving at the same time their efficiency. The pharmaceutical forms using liposomes ensure the controlled release of medicine, as a result of the encapsulation of the active substances in the amphiphile structure�liposomes, with the possibility to diminish irritating secondary reactions in various forms of acne, and to provide efficiency, tollerability, conformity and cosmetic acceptability, to be proved in a future study.
