Baclofen (brand names Kemstro, Lioresal, Liofen, Gablofen, and Beklo) is a derivative of gamma-aminobutyric acid (GABA). It is primarily used to treat spasticity and is in the early research stages for use for the treatment of alcoholism.

It is an agonist for the GABAB receptors. Its beneficial effects in spasticity result from actions at spinal and supraspinal sites. Baclofen can also be used to treat hiccups, and has been shown to prevent rises in body temperature induced by the drug MDMA in rats.

In addition, research has shown baclofen to be effective in the treatment of alcohol dependence and withdrawal, by inhibiting both withdrawal symptoms and cravings.

A beneficial property of baclofen is that tolerance does not seem to occur to a significant degree — baclofen retains its therapeutic anti-spasmodic effects even after many years of continued use. Newer studies, however, indicate that tolerance may develop in some patients receiving intrathecal baclofen treatment.

Oral dosage must be carefully regulated; significantly high doses of the drug, particularly 80 mg per day or higher, can cause excessive ataxia and/or drowsiness that can interfere with daily function.
