Risedronate Sodium
Your body is constantly breaking down old bone and making new bone tissue. If you have osteoporosis, your body breaks down more bone than it forms so gradually bone loss occurs and your bones become thinner and fragile. This is especially common in women after menopause (change of life). Many people with osteoporosis have no symptoms and you may not even know that you have it. However, osteoporosis makes you more likely to have fractures (break bones), especially in your spine, hips and wrists.Risedronate has an affinity for hydroxyapatite crystals in bone and acts as an antiresorptive agent. At the cellular level, Risedronat inhibits osteoclasts. The osteoclasts adhere normally to the bone surface but show evidence of reduced active resorption.
