Pharmacological actionBaclofen is centrally acting muscle relaxant; GABAB-receptor agonist. It depresses mono-and polysynaptic reflexes presumably by reducing the release of excitatory amino acids (glutamate and aspartate) from the terminals which occurs as a result of stimulation of presynaptic GABA-receptors. This medication does not affect the transmission of impulses in the nerve-muscle synapses; reduces skeletal muscle tone; has a moderate analgesic effect.

Plasma protein binding is about 30%. Baclofen crosses the placental barrier, excreted in breast milk; metabolized in the liver; excreted in the urine, mainly unchanged.
