Goldcal Alen 70mg/5600IU Tablet is a combination medication containing Alendronic Acid 70mg and Vitamin D3 5600IU, primarily indicated for the treatment and prevention of osteoporosis in postmenopausal women and other conditions associated with decreased bone density. Alendronic Acid, a bisphosphonate, acts by inhibiting osteoclast-mediated bone resorption, thereby increasing bone mineral density and reducing the risk of fractures. Vitamin D3 (cholecalciferol) facilitates calcium absorption from the gastrointestinal tract and supports bone mineralization, enhancing the therapeutic efficacy of Alendronic Acid. This formulation is typically prescribed for patients at high risk of fractures, including those on long-term corticosteroid therapy or with established osteoporosis. Administration should be on an empty stomach with a full glass of water, and patients are advised to remain upright for at least 30 minutes post-dose to minimize esophageal irritation. Regular monitoring of serum calcium and vitamin D levels is recommended to ensure optimal treatment response and prevent hypocalcemia. Goldcal Alen 70mg/5600IU Tablet offers a convenient once-weekly dosing regimen that improves compliance and supports bone health maintenance in at-risk populations. It should be used under medical supervision with attention to contraindications such as esophageal abnormalities and hypocalcemia.
