Acamprosate is used to assist with alcohol abstinence. Acamprosate is compound that is structurally very closely related to taurine. Would taurine be as effective for alcohol abstinence as acamprosate? Sometimes small changes in molecular structure can have large effects on the actions of drugs. Acamprosate could have advantages over taurine for alcohol dependence but then again maybe the advantage of acamprosate was that at one time acamprosate was patentable.
Acamprosate agonizes GABA A receptors and modulates NMDA receptors Taurine, however, is a also a powerful activator of GABA A receptors and also modulates NMDA receptors. There might not be much biochemical advantage to acamprosate compared to taurine.
