Anterior pituitary, adrenal, and gonadal hormones during cocaine withdrawal
Abstract
Plasma luteinizing hormone (LH), prolactin, testosterone, and cortisol levels were determined in 16 patients after hospital admission for cocaine abuse, during the course of 4 weeks of hospitalization, and before discharge. Hyperprolactinemia was found at admission (mean +/- SD, 27.5 +/- 10.2 ng/ml) and persisted until discharge (mean +/- SD, 28.7 +/- 10.8 ng/ml). Plasma LH, testosterone, and cortisol levels were within normal limits. These findings suggest that persistent elevation of plasma prolactin levels after cocaine withdrawal may reflect a chronic cocaine-induced derangement in neural dopaminergic regulatory systems.
