Naloxone attenuates drinking behavior in psychiatric patients displaying self-induced water intoxication.

Abstract
1. The present study was performed to examine the effect of naloxone on drinking behavior in three schizophrenic inpatients with psychosis, intermittent hyponatremia, and polydipsia. 2. Their body weight were checked five times daily and the maximum weight gain during a day was chosen as an index of their polydipsia. 3. After control recording for six weeks, a daily naloxone (0.6 mg) injection series was performed once every two weeks for three series (six weeks). Withdrawal of this drug for six weeks resulted in weight gain recovering to control level. 4. The present study showed that naloxone seems to be a potential treatment for psychiatric patients displaying self-induced water intoxication and that endogenous opioid systems are involved in the compulsive drinking behavior of this syndrome.
