Long-term phenothiazine treatment does not cause pituitary tumours. 1984

In order to explore the possibility that prolactinomas may be caused by prolonged under-inhibition of prolactin-secreting cells we examined the pituitary fossa in 69 patients on long-term phenothiazine treatment. The average duration of treatment was 12.5 years and 55 (80 per cent) of the patients had persistently raised serum prolactin levels. The incidence of radiologically detectable pituitary fossa abnormalities was not significantly different to that in control populations. In 62 per cent of patients the skull x-rays from an earlier admission were available. Comparison of these with earlier films did not show a higher incidence of pituitary fossa abnormalities after prolonged exposure to phenothiazines.

UI MeSH Term Description Entries
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010640 Phenothiazines Compounds containing dibenzo-1,4-thiazine. Some of them are neuroactive.
D010911 Pituitary Neoplasms Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.

D011388 Prolactin A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.
