 <blockquote>Hypercalcaemia is a common disorder normally caused by primary hyperparathyroidism (PHPT) or malignancy. A proportion of cases present as an emergency, which carries a significant mortality. Emergency management of hypercalcaemia is based on intravenous rehydration with normal saline but when this is inadequate, bisphosphonate therapy is used; more recently the novel anti-resorbtive agent denosumab has been shown to have a useful role in treatment.  <blockquote>Hypercalcaemia is a common disorder normally caused by primary hyperparathyroidism (PHPT) or malignancy.

 +The active form of vitamin D3 , calcitriol, is a potent antiproliferative compound. However, when effective antitumor doses of calcitriol are used, hypercalcemic effects are observed, thus blocking its therapeutic application. (({{pmid>long:    31025400}}))

-Since calcitriol (the active form of vitamin D) is a Vitamin D receptor (VDR) agonist, and use of this substance can cause hypercalcemia, one may expect that olmesartan, through effects on the VDR, may also cause hypercalcemia if the dosage is high. There is however no evidence that this is an effect of olmesartan, and the reason for the differing effects appears to reside in the non-VDR effects of calcitriol.
