THERAPEUTIC CLASSIFICATION
Muscle Relaxant and Antispastic Agent
ACTION
The
precise
mechanisms
of
action
of
baclofen
are
not
fully
known.
It
inhibits
both
monosynaptic and polysynaptic reflexes at the spinal level, probably
by hyperpolarization of
afferent terminals, although actions at supraspinal sites may also
occur and contribute to its
clinical effect. Although baclofen is an analog of the putative
inhibitory neurotransmitter
gamma-aminobutyric acid (GABA), there is no conclusive evidence that
actions on GABA
systems are involved in the production of its clinical effects.
Peak plasma concentrations of baclofen are achieved within 2 hours and
the plasma half-life is
approximately 2-4 hours.
INDICATIONS
phl-BACLOFEN is useful for the alleviation of signs and symptoms of
spasticity resulting from
multiple sclerosis.
phl-BACLOFEN may also be of some value in patients with spinal cord
injuries and other
spinal cord diseases.
