Salcatonin
Salcatonin is the type of calcitonin hormone found in salmon.[1]
As in humans, salmon calcitonin is a peptide hormone secreted by the parafollicular cells of the thyroid gland in response to hypercalcemia, and lowers blood calcium and phosphate by promoting renal excretion.
Therapeutic usage[]
Synthetic salmon calcitonin may be used therapeutically in humans, as it is twenty times more active than human calcitonin and has a longer half-life. It is used as therapy for Paget's disease and severe hypercalcemia. It is also used as a therapy against osteoporosis (working as an inhibitor of osteoclastic resorption), having an effectiveness of 40-50 times that of the human analogue.[1]
Pharmaceutical salmon calcitonin formulations[]
Calcitonin, as salmon calcitonin (sCT), is available in the pharmaceutical market as an injectable preparation for intravenous, intramuscular or subcutaneous application. Noninvasive sCT preparation as a nasal spray is commercially produced and received US FDA approval under the proprietary name Miacalcin® in 1975 for the treatment of postmenopausal osteoporosis. The bioavailability of Miacalcin® nasal spray relative to the injectable form is between 3% and 5%.[2] Currently, a number of sCT oral preparations are under clinical trials and at least one of them has reached Phase III of clinical approval.[3]
