Evocalcet (MT-4580, KHK7580) is an allosteric calcium-sensing receptor agonist. Evocalcet directly acts on calcium receptors on parathyroid cells to suppress synthesis and secretion of parathyroid hormone (PTH), and it consequently decreases serum PTH and serum calcium. ORKEDIA® TABLETS (generic name: evocalcet, code name: KHK7580) has been listed on the National Health Insurance (NHI) Drug Price List and launched for the treatment of secondary hyperparathyroidism in patients on maintenance dialysis in Japan.

Sample Use Guides

In general, for adults, start by taking 1 tablet (1 mg of the active ingredient) at a time, once daily, then the dosage may be adjusted between 1 to 8 tablets (1 to 8 mg) by observing PTH and serum calcium level. Depending on your condition, the dosage may start from 2 tablets (2 mg) at a time, once daily. The maximum daily dose is limited to 12 tablets (12 mg). Dose should be increased by 1 tablet (1 mg) at a time, at intervals of at least two weeks. Strictly follow the instructions.
