Medically reviewed by Min Clinic Staff | Updated: January 2026

Guaiacol glyceryl ether carbamate - General Information

A centrally acting muscle relaxant whose mode of action has not been established. It is used as an adjunct in the symptomatic treatment of musculoskeletal conditions associated with painful muscle spasm. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1206)

 

Pharmacology of Guaiacol glyceryl ether carbamate

Guaiacol glyceryl ether carbamate is a central muscle relaxant for skeletal muscles, used to treat spasms. It is structurally related to guaifenesin. Guaiacol glyceryl ether carbamate's exact mechanism of causing skeletal muscle relaxation is unknown. It is thought to work centrally, perhaps by general depressant effects. It has no direct relaxant effects on striated muscle, nerve fibers, or the motor endplate. It will not directly relax contracted skeletal muscles. The drug has a secondary sedative effect.
