It’s believed that alcohol abuse is caused by neurotransmitter imbalances that result in enhanced craving in an alcohol addicted person. So the chemical imbalance in the brain reinforcing addiction. Acamprosate, the active ingredient in the Acamptas pill inhibits neurotransmitter receptors called glutaminergic N-methyl-D-aspartate receptors. Also, it activates the gamma-aminobutyric acid type A receptors. This whole process ultimately results in reducing the craving of consumption and reduces alcohol withdrawal symptoms. Acamptas drug is not metabolized in the liver; therefore, people with liver disorders can take this drug.
