What is Risedronate Weekly Cinfa
Risedronate Weekly Cinfa belongs to a group of non-hormonal medicines called bisphosphonates, which are used to treat bone diseases. It acts directly on the bones, strengthening them and thus reducing the likelihood of fractures.
Bone is a living tissue. Old bone tissue in the skeleton is constantly being renewed and replaced by new bone tissue.
Postmenopausal osteoporosis occurs in women after menopause when the bone begins to weaken, becomes more fragile, and is more likely to fracture after a fall or twist.
Osteoporosis can also affect men due to various causes, including aging and/or low levels of male hormone, testosterone.
The most likely bone fractures are those of the vertebrae, hip, and wrist, although they can occur in any bone in the body. Osteoporosis-related fractures can also cause back pain, loss of height, and a curved back. Some patients with osteoporosis may not have symptoms and may not even know they have it.
