Arbaclofen hydrochloride is a Gamma-Aminobutyric Acid derivative that is a specific agonist at GABA-B receptors (RECEPTORS, GABA-B). It is used in the treatment of spasticity, especially that due to spinal cord damage. Its therapeutic effects result from actions at spinal and supraspinal sites, generally the reduction of excitatory transmission.

How to use

In Vivo:

(R)-Baclofen hydrochloride (STX 209 hydrochloride) suppresses audiogenic seizures in the Fmr1-knockout mouse on the seizure-resistant C57BL/6 background with an effective dose of 1 mg/kg. Acute intraperitoneal administration of (R)-Baclofen hydrochloride significantly reduces the percent of mice displaying seizures (seizure incidence), with a minimum effective dose (MED) of 1.5 mg/kg.
