THERAPEUTIC CLASSIFICATION
Antispastic Agent
CLINICAL PHARMACOLOGY
The precise mechanisms of action of LIORESAL (baclofen) as an
antispastic agent are not fully
understood. Baclofen inhibits both monosynaptic and polysynaptic
reflex transmission at the
spinal level, possibly by decreasing excitatory neurotransmitter
release from primary afferent
terminals. Actions at supraspinal sites may also contribute to its
clinical effect. Baclofen is an
analogue of the inhibitory neurotransmitter gamma-aminobutyric acid
(GABA), and may exert
its effects by stimulation of the GABA
B
receptor subtype. _ _
Baclofen has been shown to have general Central Nervous System (CNS)
depressant properties
as indicated by the production of sedation with tolerance, somnolence,
ataxia and respiratory and
cardiovascular depression. A dose-dependent inhibitory effect on
erectile function has been
shown in men through GABA
B
receptor stimulation.
In neurological diseases associated with spasm of the skeletal
muscles, LIORESAL Intrathecal
may
have
beneficial
action
on
reflex
muscle
contractions,
painful
spasm,
automatism,
hyperreflexia, trismus and clonus. Neuromuscular transmission is not
affected by baclofen.
Baclofen may also reduce pain associated with spasticity.
