Calcium Carbonate / Risedronate
Calcium Carbonate/Risedronate is a combination medication used to treat and prevent osteoporosis. Calcium carbonate provides elemental calcium necessary for bone formation and maintenance, while risedronate belongs to a class of drugs called bisphosphonates that slow bone loss by reducing the activity of bone-breaking cells. This combination is commonly prescribed for postmenopausal women and men at risk of osteoporosis-related fractures.

Treatment and prevention of osteoporosis in postmenopausal women, treatment of osteoporosis in men, and may be used in Paget's disease of bone or other conditions involving bone loss.
Risedronate inhibits osteoclast-mediated bone resorption by binding to bone mineral and reducing bone turnover, while calcium carbonate provides elemental calcium to support bone mineralization and maintain serum calcium levels.
Take risedronate on an empty stomach first thing in the morning with plain water only; remain upright for at least 30 minutes after dosing. Separate calcium supplements by several hours from risedronate dosing to ensure proper absorption. Rare but serious risks include osteonecrosis of the jaw and atypical femoral fractures. Report any unusual bone pain, jaw problems, or thigh/groin pain to your healthcare provider.
