A Case of Drug Induced Nephrogenic Diabetes Insipidus and Hyperprolactinemia in Schizophrenia Simultaneously / 대한내분비학회지

In schizophrenia, when treatment using antipsychotics fails, lithium, which is known as an antimanic drug, can also be administered. It is reported that 12~20% of patients taking lithium develop nephrogenic diabetes lactotrophs. Hyperprolactinemia is induced by typical antipsychotics, as they block the dopamine-2 receptors of latotrophs in the pituitary gland. Therefore, atypical antipsychotics for decreasing the side effect, such as hyperprolactinemia, can be used. However, hyperprolactinemia can be induced by risperidone, one of the atypical antipsychotics. Here, a case of drug induced nephrogenic diabetes insipidus and simultaneous hyperprolactinemia, which occurred in a patient with schizophrenia, is reported.
