Central muscle relaxants act by
Refer KDT 6/e p 348 Centrally acting muscle relaxants reduce skeletal muscle tone by a selective action in the cerebrospinal axis, without altering consciousness They selectively depress spinal and supraspinal polysynaptic reflexes Polysynaptic pathways in the ascending reticular formation which are involved in the maintenance of wakefullness
Decreasing muscle excitation
Decreasing spinal polysynaptic reflexes
Inhibiting spinal polysynaptic reflexes
Decreasing nerve conduction
