Two patients receiving gallium nitrate and one patient receiving calcitonin developed acute renal failure in a controlled trial of patients with cancer-related hypercalcemia.
Like the other triptans sumatriptan and zolmitriptan, rizatriptan induces vasoconstrictionpossibly by inhibiting the release of calcitonin gene-related peptide from sensory neurons in the trigeminal nerve.
Medullary thyroid cancer develops in cells in the thyroid gland that make a hormone called calcitonin, which helps maintain a healthy level of calcium in the blood.
