Full drug detail

Overview

Calcitriol, also known as 1,25-dihydroxycholecalciferol, is a potent form of vitamin D used in veterinary medicine to manage calcium and phosphorus metabolism in pets. It is particularly beneficial for animals with chronic kidney disease and certain parathyroid disorders.

How It Works

Calcitriol functions by enhancing the absorption of calcium and phosphate in the gut, promoting bone mineralization, and reducing parathyroid hormone levels. This helps maintain appropriate calcium balance in pets, which is crucial for many physiological processes.

Uses & Indications

Calcitriol is primarily used to treat conditions related to abnormal calcium and phosphorus metabolism, including:

  • Chronic kidney disease
  • Secondary hyperparathyroidism
  • Hypocalcemia

Dosage Guidelines

Dogs

  • Small Dogs: 0.5 to 1 ng/kg orally once daily
  • Medium Dogs: 1 to 2 ng/kg orally once daily
  • Large Dogs: 2 to 3 ng/kg orally once daily
