Osteoporosis Drug Removed from the Market
Health Canada released information on Calcitonin (Salmon) Nasal Spray’s market withdrawal several weeks ago. In addition to Canada’s move the European Medicines Agency (EMA) also removed this drug as well due to increases in cancer risk.
Calcitonin is an agent that increases calcium in the bone and lowers calcium levels in the blood, which is used for both osteoporosis and Paget’s disease. This information was a result of two studies conducted on the possible release of an oral form of Calcitonin when the increased cancer risk was found.
Evidence surfaced that prolonged use of Calcitonin is associated with increased cancer risk and therefore the risk benefit reward has changed. Although the cancer rates reported in the studies were low, the increase in cancer rates seen with calcitonin varied between 0.7% in studies with the oral formulation to 2.4% in the studies with the nasal formulation. Taking into account the increased rate of cancer with long-term use and the limited benefit of calcitonin when used to treat post-menopausal osteoporosis to reduce the risk of vertebral fractures, the CHMP concluded that the benefits of calcitonin did not outweigh the risks in this condition. As the nasal spray is only used in osteoporosis, the CHMP recommended that this formulation should no longer be used (European Medicines Agency, 2013).
Health Canada will not remove the drug until October 1st 2013. The European Medicines Agency along with Health Canada will still sell the injectable form of Calcitonin for Paget’s, hypercalcemia and for prolonged immobilization to prevent bone loss, but only for a short period of time.
Since the drug will remain on the market till October, this will give health care professionals time to prescribe an alternate medication.
