THERAPEUTIC CLASSIFICATION
Antispastic Agent
ACTION AND CLINICAL PHARMACOLOGY
MECHANISM OF ACTION (MOA)
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
2 – 4 hours.
_SPECIAL POPULATIONS _
GERIATRICS (AGED 65 YEARS OR ABOVE)
Following a single oral dose, elderly patients have a slower rate of
absorption and elimination, a
slightly prolonged elimination half-life, but a similar systemic
exposure of baclofen compared to
young adults.
HEPATIC IMPAIRMENT
No pharmacokinetic data is available in patients with hepatic
impairment after administration of
baclofen. However, as the liver does not play a significant role in
the disposition of baclofen, it is
unlikely that baclofen pharmacokinetics would be altered to a
clinically significant level in
patients with hepatic impairment.
RENAL IMPAIRMENT
No controlled clinical pharmacokinetic study is available in patients
with renal impairment after
administration of baclofen. Baclofen is predominantly eliminated
unchanged in urine. Sparse
plasma concentration data collected in female patients under chronic
hemodialysis or
compensated renal failure indicate significantly
