Bioactivity | Methocarbamol is an orally active central muscle relaxant and blocks muscular Nav1.4 channel. Methocarbamol reversibly affects voltage dependence of inactivation of Nav1.4 channel. Methocarbamol has the potential for muscle spasms and pain syndromes research[1][2][3]. | ||||||||||||
Invitro | Methocarbamol (2 mM; for 20 min) significantly increases the decay times of the EPCs and those of the EPPs induced by the phrenic nerve stimulation[3]. Methocarbamol has no effect on Nav1.7 currents[3]. | ||||||||||||
In Vivo | Methocarbamol (200 mg/kg; ip) has Muscle relaxant activity of 88.96%[3]. Animal Model: | ||||||||||||
