Bisphosphonate preparations

Pharmacology

Risedronate has an affinity for hydroxyapatite crystals in bone and acts as an antiresorptive agent. At the cellular level, Risedronate inhibits osteoclasts. The osteoclasts adhere normally to the bone surface, but show evidence of reduced active resorption.

Calcium suppresses parathyroid hormone (PTH) secretion and decreases bone turnover. Increased levels of PTH are known to contribute to age-related bone loss, especially at cortical sites, while increased bone turnover is an independent risk factor of fractures.

Dosage

This is a co-package product containing 1 tablet of Risedronate Sodium 35 mg for once weekly dosing and 6 tablets of Calcium Carbonate 500 mg for daily dosing of the remaining 6 days of the week. Risedronate is in a group of medicines called bisphosphonates. It alters the cycle of bone formation and breakdown in the body. It slows bone loss while increasing bone mass, which may prevent bone fractures.
