Use of Chlorphenesin carbamate

Chlorphenesin carbamate is a centrally acting skeletal muscle relaxant. Chlorphenesin carbamate can be used for the research of pain and discomfort related to skeletal muscle trauma and inflammation[1]. Chlorphenesin carbamate is a selective blocker of polysynaptic pathways at the spinal and supra-spinal levels[2]. Antinociceptive effect[3].

In Vivo	Chlorphenesin carbamate (CPC; 50 mg/kg i.v.) inhibits the mono (MSR) and poly-synaptic reflex (PSR), the latter being more susceptible than the former to CPC depression. Chlorphenesin carbamate has an apparent depressant action on the spinal neuron, and it hyperpolarized both the ventral and dorsal roots of the isolated frog spinal cord[2]. Chlorphenesin carbamate (CPC) has an antinociceptive action in adjuvant arthritic rats. Chlorphenesin carbamate (100-400 mg/kg, p.o.) has a dose-dependent antinociceptive effect in the behavioral study. Chlorphenesin carbamate (25-50 mg/kg, i.v.) depresses the evoked neuronal responses of nociceptive neurons in the ventrobasal thalamus (VB) in the electrophysiological study. Chlorphenesin carbamate (50 mg/kg, i.v.) depresses the spontaneous firings of the VB nociceptive neurons[3]. Animal Model: Male Wister rats weighing 200-300 g[3] Dosage: 50 mg/kg Administration: Intravenously administered Result: Significantly inhibited PSR, with the maximum inhibition at 40 min after the drug administration.
