The effects of the acute administration of phencyclidine hydrochloride (PCP) on the release of corticosterone, growth hormone and prolactin in the rat.

There is little information on the neuroendocrine effects of PCP. The present study examined the effects of the acute subcutaneous administration of PCP on serum levels of corticosterone, growth hormone and prolactin in the male rat. PCP increased serum levels of corticosterone, decreased serum levels of prolactin and failed to affect growth hormone levels. The results indicate that, like other drugs of abuse, PCP alters neuroendocrine function.
