Alendronic acid
Summary
Alendronic Acid is used to prevent and treat weak bones (osteoporosis) in postmenopausal women and men. It is also beneficial for people whose bones have weakened due to steroid medications, and those with a bone disease called Paget's disease.
Alendronic Acid works by inhibiting bone resorption. It sticks to the bone and stops the cells that break down bone from working, which slows down bone loss and indirectly helps bone building.
For osteoporosis treatment, the dosage is 10 mg daily or 70 mg weekly. For prevention, it's 5 mg daily or 35 mg weekly. For Paget's disease, it's 40 mg daily for 6 months. Always follow your doctor's prescription.
Common problems include stomach upset, pain, heartburn, constipation, diarrhea, nausea, and aches in bones, joints, or muscles. Rarely, more serious problems like esophagus problems, low calcium, severe bone pain, jaw problems, or unusual thigh bone fractures can happen.
Alendronic Acid can cause serious problems like trouble swallowing, low calcium, bone pain, jaw problems, and broken bones. Take it exactly as directed, drink a full glass of water with it, stay upright for at least 30 minutes afterward, and tell your doctor right away if you have chest pain, heartburn, or trouble swallowing. Ensure your calcium levels are okay before you start taking this medicine.
Indications and Purpose
How does Alendronic acid work?
Alendronic acid works by slowing down the process of bone breakdown, which helps maintain or increase bone density. It belongs to a class of drugs called bisphosphonates. Think of it like a brake on bone loss, allowing your body to build stronger bones over time. This action reduces the risk of fractures in conditions like osteoporosis, which is a disease that weakens bones. By preserving bone strength, Alendronic acid helps improve overall bone health.
Is Alendronic acid effective?
Yes, Alendronic acid is effective for treating osteoporosis, which is a condition that weakens bones. It works by slowing bone loss and increasing bone density, reducing the risk of fractures. Clinical studies show that Alendronic acid significantly improves bone health in people with osteoporosis. It is also used to treat other bone conditions like Paget's disease, which causes abnormal bone growth. Always follow your doctor's instructions to ensure the best results from this medication.
