Background:

(R)-Baclofen Hcl(STX-209 Hcl) is a derivative of gamma-aminobutyric acid (GABA) primarily used to treat spasticity and is in the early research stages for use for the treatment of alcoholism.Target: GABABaclofen (brand names Kemstro, Lioresal, Liofen, Gablofen, Beklo and Baclosan) 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 also used by compounding pharmacies in topical pain creams as a muscle relaxant.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 andcravings.
