General Mechanism of Action of Antipsychotic Drugs It has been observed that from a pharmacodynamic perspective, all antipsychotics share a common feature: they reduce dopaminergic neurotransmission. Ii is assumed to generate active oxygen species , interfere with the electron transport in the parasite, or bind to and alter the properties of protozoal DNA. The mechanism of action (or MOA) of a drug is the causal, biochemical manner in which it produces effects in the body. Yet its mechanism of action is still poorly understood. ENBREL is a dimeric fusion protein consisting of the extracellular ligand-binding portion of the human 75-kilodalton (p75) tumor necrosis factor receptor (TNFR) linked to the Fc portion of human IgG1.
