in vivo
Propiomazine (0.2 mg/kg, nasal administration, rats) hydrochloride is quickly absorbed, followed by rapid reduction of the plasma concentrations[3].
Propiomazine (25 mg/kg, i.p., at 0 and 3 h after challenge) hydrochloride protects rats against CCl4-induced hepatic injury[4].
Propiomazine (0.31-20 mg/kg, i.v.) hydrochloride increases plasma prolactin concentrations in rats[5].
