benzodiazepines in the treatment of spasticity
Last reviewed 01/2018
- act via the facilitation of gamma-aminobutyric acid (GABA) neurotransmission
at various supraspinal levels and in the spinal cord
- there is evidence from small randomised, double-blind, placebo-controlled
trials that diazepam reduced painful muscle spasms and led to a partial resolution
of spasticity - however there was no improvement in muscle power (1,2)
- the sedative effects of diazepam last for less time than the its antispasmodic effects - therefore diazepam (in the treatment of spasticity) is best administered as a single dose at night
