Pifexole
Pifexole is a biologically active 3,5-disubstituted-1,2,4-oxadiazole compound. Pifexole exhibits antispasmodic and muscle relaxant activities, with no effect on monosynaptic knee-jerk reflex. Pifexole can be used in studies related to muscle relaxation and spasm.

Biological Activity
Pifexole (15.4-200 mg/kg; p.o.) inhibits electroshock-induced convulsions in rats and mice with ED50 values of 17.5 mg/kg and 15.4 mg/kg, respectively, and inhibits strychnine-induced convulsions in both species with an ED50 of 96 mg/kg, while antagonizing nicotine toxicity in mice with an ED50 of 30 mg/kg. Pifexole also reduces muscle strength in mice by 25% and 35% at 100 mg/kg and 200 mg/kg, respectively, inhibits spontaneous activity in mice at 100 mg/kg, and reduces morphine-induced excitation and hyperactivity at 200 mg/kg[2]
