Ans. C. Dexamethasone
* Dexamethasone is used in the treatment of hypercalcemia due to vitamin D toxicity. Glucocorticoid (Dexamethasone, prednisolone, etc) therapy will decrease plasma calcium levels by blocking the action of vitamin D(1,25 D) which results in reduced intestinal calcium absorption and increased urinary excretion of calcium.
* Other drugs like chloroquine and hydroxychloroquine are less effective in treating hypercalcemia due to vitamin D toxicity.
