Adapalene
Mechanistically, adapalene binds to specific retinoic acid nuclear receptors (gamma and beta) and retinoid X receptors but does not bind to...
Acitretin
The mechanism of action of acitretin is unknown, however it is believed to work by targeting specific receptors (retinoid receptors such as...
Aciclovir
Viral (HSV-1, HSV-2 and VZV) thymidine kinase converts aciclovir to the aciclovir monophosphate, which is then converted to the diphosphate...
Acetylsalicylic acid
The analgesic, antipyretic, and anti-inflammatory effects of acetylsalicylic acid are due to actions by both the acetyl and the salicylate...
