Classification of drugs by biochemical mechanism of action

: Biochemical drugs classification is proposed. Drugs are divided into 6 classes, according to their action on: 1) signal-transduction systems, 2) other components of plasmatic membranes, 3) intracellularly, 4) gene therapy, 5) extracellularly, 6) invasive agents. Concrete biochemical mechanisms of action of every class drugs are considered and described.
