Acute effects of mazindol on the secretion of ACTH, beta-lipotropin, beta-endorphin and cortisol in man

The effects of mazindol, an anorexiant, on the secretion of anterior pituitary and adrenocortical hormones were examined in healthy male volunteers and in patients with Addison's disease. In healthy male volunteers, significant elevations in plasma ACTH, beta-endorphin, beta-lipotropin and growth hormone were induced by mazindol administration, though no changes were observed in plasma thyrotropin, luteinizing hormone, follicle-stimulating hormone or prolactin. Plasma ACTH increased in patients with Addison's disease, too. In addition, plasma cortisol increased, without a change in the plasma aldosterone levels after mazindol administration to normal subjects.
