In Vivo Dapiprazole hydrochloride (0-10 mg/kg or 0-3 mg/mice; i.p. or i.c.v.; once) reduces the overall severity of the opiate withdrawal symptoms in mice[1]. Animal Model: Swiss Albino male CD-1 mice weighing 20 -25 g, acute dependence model (mice were injected i.p. with morphine (25 mg/kg) and 2 h later with naloxone (12.5 mg/kg))[1] Dosage: 5, 7.5 and 10 mg/kg (i.p.) or 0.5, 1 and 3 mg/mice (i.c.v.), once Administration: Intraperitoneal injection or intracerebroventricular administration, once Result: Decreased jumping behavior, head shakes and paw shakes when administered just before naloxone. Resulted in a notable suppression of morphine withdrawal symptoms in a dose-related fashion when injected i.c.v..
