Acamprosate reduces motor cortex excitability determined by transcranial magnetic stimulation.

Acamprosate is effective in reducing alcohol intake in weaned alcoholics. We were interested if acamprosate had an effect on the excitability of cortical motoneurons determined by transcranial magnetic stimulation (TMS). We studied 12 male healthy volunteers (mean age 29.

Effects of acamprosate on memory in healthy young subjects.

Objective: Several studies have shown acamprosate (calciumacetylhomotaurinate) to increase abstinence rates in weaned alcoholics. Chronic alcoholics often suffer from cognitive deficits. Since acamprosate appears to interact with N-methyl-D-aspartate (NMDA) receptors, a subclass of glutamate receptors playing an important role in learning and memory processes, this study was performed in order to investigate different cognitive functions during administration of acamprosate.

Lack of psychotomimetic or impairing effects on psychomotor performance of acamprosate.

The possible effects on psychomotor performance, concentration, attention, and mood of acamprosate (calciumacetylhomotaurinate) were assessed using a randomized, double-blind, cross-over, placebo-controlled design involving 12 healthy male volunteers. Acamprosate 2 g daily per os or placebo was administered for seven days and separated by washout intervals of at least 21 days. Objective tests evaluated psychomotor functions (simple reaction time measurement, binary choice reaction test, computerized visual searching task, sustained attention test).
