In the present study, we investigated the role of vasopressin in the development of quinpirole-induced hyperdipsia in the rat. We report that: (1), an acute intraperitoneal (i.p.) injection of 0.56 mg/kg of quinpirole increased plasma vasopressin (radioimmunoassay) at 15 min but not at 30 or 120 min; (2), nine daily injections of quinpirole (0.56 mg/kg, i.p.) progressively increased water intake and diuresis for a period of several hours after each treatment; (3), quinpirole hyperdipsia was associated with apparently normal levels of vasopressin (which might be considered inappropriately high in the presence of excessive drinking); (4), quinpirole reduced vasopressin and oxytocin, but not angiotensin, immunoreactivity in the supraoptic nucleus. These findings suggest that quinpirole hyperdipsia is a sound animal model of psychotic polydipsia.
