Calbotol

N/A

Calcitriol & Calcium combination is indicated for Osteoporosis, Hypoparathyroidism, Hypocalcaemia, Osteomalacia rickets, Renal osteodystrophy.

N/A

Hypercalcaemia; evidence of vitamin D toxicity, pregnancy & lactation.

Calcium salt can be used in the prevention and treatment of calcium deficiency states or negative calcium balance. It is also used as an adjunct in the prevention and treatment of osteoporosis.Calcitriol promotes calcium absorption in the intestines and retention at the kidneys thus increasing serum calcium levels. It also increases renal tubule phosphate resorption consequently decreasing serum phosphatase levels, PTH levels and bone resorption.

Calcium: Co-administration with thiazide diuretics or vit D may lead to milk-alkali syndrome and hypercalcaemia. Decreased absorption with corticosteroids. Decreases absorption of tetracyclines, atenolol, iron, quinolones, alendronate, Na fluoride, Zn and calcium-channel blockers. Enhances cardiac effects of digitalis glycosides and may precipitate digitalis intoxication.Calcitriol: Hypermagnesaemia may develop in patients on chronic renal dialysis. Hypercalcaemia in patients on digitalis may precipitate cardiac arrhythmias. Intestinal absorption of calcitriol may be reduced by cholestyramine and colestipol. Phenytoin, barbiturates may decrease the T1/2 of calcitriol. May develop hypercalcaemia with thiazide diuretics.

Pregnancy Category-C. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks

Idiopathic hypercalcaemia. Pediatric doses must be individualised and monitored under close medical supervision. Coronary disease, renal function impairment and arteriosclerosis, especially in the elderly. Hypoparathyroidism.
