A 28-year-old male sustained anoxic brain damage following aborted cardiac arrest, and subsequently developed severe muscular rigidity and spasticity involving all extremities. The spasticity was refractory to the standard regimens used for spastic hypertonia. Zolpidem dramatically inhibited muscular rigidity, spasticity, and dystonic posturing in a dose-dependent manner, resulting in a sustained improvement of his global performance over four years. The authors postulate a central mechanism of action by selective inhibition of GABAergic inhibitory neurons, and suggest a controlled clinical study to investigate the potential efficacy of zolpidem in relieving spasticity related to postanoxic brain injury.

Zolpidem, a non-benzodiazepine hypnotic, acts selectively via the alpha(1)-subunit of GABA(A) receptors at therapeutic doses. It is therefore thought to lack both benzodiazepine properties such as anxiolysis, anticonvulsion, muscle relaxation, and side effects such as dependency. We report a case of severe dependency of zolpidem taken because of percieved myorelaxation in a patient with multiple sclerosis and paraspasticity. The observations in the patient described here suggest that zolpidem looses alpha1-receptor selectivity at higher doses, thereby leading to the same risks and benefits such as benzodiazepines. This should be taken into account by doctors when prescribing higher doses. Zolpidem may improve symptoms of spasticity in high doses via affection of GABA alpha2-receptor and alpha3-receptor subunits.
