Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

hy·per·cal·ce·mi·a

(hī'pĕr-kal-sē'mē-ă)
An abnormally high concentration of calcium compounds in the circulating blood; commonly used to indicate an elevated concentration of calcium ions in the blood.
Synonym(s): calcemia, hypercalcaemia.

hypercalcaemia

An excess of calcium in the blood. This may be due to excessive intake of calcium in the diet, prolonged immobilization, over-production of PARATHYROID hormone causing undue release of calcium from bones, malignant disease of bone and various non-bony cancers that produce a parathyroid hormone-like polypeptide.

hypercalcaemia

having excessive levels of calcium in the plasma.

(hī'pĕr-kal-sē'mē-ă)

Synonym(s): hypercalcaemia.

Calcium channel blocking agents like verapamil, nifedipine and diltiazem are commonly used in the treatment of hypertension, angina, myocardial infarction and supraventricular tachycardia.6 Induction of hypercalcaemia through intravenous administration of calcium, is usually associated with increased gastric volume and acidity.7,8 The acid stimulating ability of calcium; is well known and there is extreme sensitivity to calcium in patients with Z-E syndrome.9,10 Calcium channel blocker Verapamil may interfere with H+K+ ATP ase due to its high affinity for the site H+K+ATP ase system which is accessible from luminal side of the stomach.11
