MedKoo Cat#: 414946 | Name: Pifexole

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Pifexole is the 1,2,4-oxadiazole derivative. It has a similar profile of muscle-relaxant activity in animals to that of chlorzoxazone. In rats, pifexole is reported to be seven times more potent than chlorzoxazone in inhibition of strychnine-induced convulsions.
