Benefits of Catirol Capsule

Treatment of Metabolic Bone disease
Catirol Capsule helps treat metabolic bone diseases by correcting abnormalities in calcium and phosphate balance and improving bone mineralisation. In renal osteodystrophy and secondary hyperparathyroidism due to chronic kidney disease, it improves calcium absorption, corrects hypocalcaemia, and lowers elevated parathyroid hormone levels, helping reduce bone pain and skeletal changes. In hypoparathyroidism and rickets, it restores calcium and phosphate levels, supporting normal bone development and strength. In post-menopausal osteoporosis, it increases calcium absorption and supports bone mineral density, helping reduce the risk of vertebral fractures.

Side effects of Catirol Capsule

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

How to use Catirol Capsule

Take this medicine in the dose and duration as advised by your doctor. Catirol Capsule may be taken with or without food.

How Catirol Capsule works

Calcitriol is the active form of vitamin D that binds to vitamin D receptors in the intestine, bone, and kidneys to regulate calcium and phosphate homeostasis. It increases intestinal absorption of calcium and phosphate, supports normal bone mineralization, and corrects hypocalcemia. In conditions such as chronic kidney disease, where endogenous calcitriol production is reduced, supplementation helps normalize parathyroid hormone levels and improve metabolic bone abnormalities
