[Effects of H2 blockers on blood levels of parathormones and calcitonin in normal subjects].

It has recently been reported that cimetidine (CMT) treatment can reduce parathormone (PTH) levels and that histamine (HA) plays an important role in the physiological modulation of PTH secretion. Thus far, no correlation has been sought with calcitonin (CT) or prolactin (PRL) which are themselves capable of modifying electrolyte and mineral homeostasis. Six healthy subjects were subjected to i.
