baclofen in the treatment of spasticity
Last reviewed 01/2018
- baclofen is a gamma-aminobutyric acid (GABA) analogue - it reduces the
release of excitatory transmitters in the spinal cord via the inhibition of
firing of alpha- and gamma-motor neurones
- there is evidence that baclofen reduces the severity and frequency of clonus
and spasticity (1)
- side effects include confusion, hypotonia, muscle weakness, fatigue and drowsiness. Abrupt withdrawal of this drug can result in visual hallucinations, cardiac arrhythmias and convulsions
