Summary

Plasma prolactin has been estimated in 69 psychiatric in-patients receiving either thioridazine (20–300 mg./day) or chlorpromazine (50–200 mg./day) or other phenothiazines. A homologous radioimmuno-assay was used which depends on an antiserum to human amniotic prolactin. Prolactin levels were significantly increased in these patients compared with control patients, and were dose related. Simultaneous estimation of growth hormone revealed normal levels.
