  Different classification systems for therapeutic agents exist.   The most  commonly used one is the ATC Code (ATC: Anatomy,   Therapeutic properties,  Chemical, pharmacological   properties). Here, an alternative  classification system   (TCAT: Target-Chemistry-Anatomy-Therapy) is  proposed which   refers to the molecular mechanism of action or rather,    target. The main subgroups of targets are: enzymes;   substrates,  metabolies, proteins; receptors; ion channels;   transporter molecules and  systems; nucleic acids,   ribosomes; physicochemical mechanisms;  antigen-antibody   reactions; unknown targets. This target-oriented  approach   may be particularly useful in teaching advanced medicinal    chemistry.
