Baclofen-d4 Chemical Properties,Usage,Production

Uses

Specific GABA-B receptor agonist. Muscle relaxant (skeletal).

Biological Activity

(±)-Baclofen-d4 is intended for use as an internal standard for the quantification of (±)-baclofen by GC- or LC-MS. (±)-Baclofen is a GABAB receptor agonist (IC50 = 180 nM).1 It induces norepinephrine release from isolated rat atria (IC50 = 4.5 μM). (±)-Baclofen (10 mg/kg) increases muscle rigidity in spastic mice.2 It inhibits the norepinephrine-induced group II flexor reflex in anesthetized rats.3 (±)-Baclofen also reduces cocaine-induced hyperlocomotion in rats and binge-like ethanol intake in mice.4,5 Formulations containing baclofen have been used to treat muscle spasms caused by multiple sclerosis and spinal cord injury.
