Description

Application

R(+)-Baclofen hydrochloride has been used as a GABA_B receptor agonist to study its effects on M43068-induced antinociception in rat models.[1] It has also been used as a GABA_B receptor agonist to study its effects on amphetamine-induced behavior and neurochemical responses in rat striatum.

Biochem/physiol Actions

Baclofen is a derivative of γ-aminobutyric acid (GABA) and acts as a 4-aminobutanoic acid receptor (GABA_B) agonist. It interacts stereospecifically with the GABA receptor and exhibits antispastic effects.Baclofen shows therapeutic effects against paroxysmal pain of trigeminal neuralgia and spinal spasticity. R(+)-Baclofen is a more active enantiomer.

Other Notes

Same enantiomer as R(−)-baclofen free base.
