Pharmacodynamics

The active substance of the drug Acamprosate, a derivative of propanosulfonic acid (3-acetamidopropane-1-sulfonic acid or N-acetylhomotaurinate calcium), inhibits glutamatergic neurotransmission due to structural similarity with endogenous gamma-aminobutyric acid (GABA) neurotransmitters.

Pharmacodynamics of the drug is not fully understood, but, presumably, due to the content of Ca 2+, Acamprosate inhibits the metabotropic N-methyl-D-aspartate receptors of the main CNS excitatory neurotransmitter L-glutamate.

The drug can also give a neuroprotective effect: exposure to calcium channels activates a number of enzymes (phospholipase, endonuclease, protease) and, thereby, helps protect nerve cells from excitotoxicity caused by excessive stimulation of neurotransmitters by ethanol.
