How Does Miacalcin Work?

Miacalcin is a manufactured version of calcitonin, a naturally occurring hormone that helps regulate bone formation and breakdown. It is actually a synthetic version of calcitonin from salmon (known as calcitonin salmon), which is more potent and longer-acting than human calcitonin. Miacalcin also appears to have some activity as a pain reliever, independent of its effects on bone.
The medication works to decrease blood calcium in several ways. First, it slows down the rate at which bone breaks down, which decreases the release of calcium from bone. Second, it increases the ability of the kidneys to excrete calcium into the urine, which helps clear calcium from the blood.
