Acefylline (INN),[1] also known as 7-theophyllineacetic acid, is a stimulant drug of the xanthine chemical class. It acts as an adenosine receptor antagonist. It is combined with diphenhydramine in the pharmaceutical preparation etanautine to help offset diphenhydramine induced drowsiness.[2]
A silanol–mannuronic acid conjugate of acefylline, acefylline methylsilanol mannuronate (INCI; trade name Xantalgosil C) is marketed as a lipolytic phosphodiesterase inhibitor. It is used as an ingredient in cosmeceuticals for the treatment of cellulite and as a skin conditioner.[3][4]
