Osteobios (CALCITONIN)

Sanofi Aventis Us · FDA-approved withdrawn Recombinant protein Verified Quality 70/100

Calcitonin salmon acts as a calcitonin receptor agonist, primarily affecting bone, with additional effects on the kidneys and gastrointestinal tract.

Calcitonin (Osteobios), marketed by Sanofi Aventis US, is a calcitonin receptor agonist primarily indicated for symptomatic Paget's disease of bone. The drug's key strength lies in its well-established mechanism of action and its current market presence, with a key composition patent expiring in 2028. The primary risk is the lack of significant revenue data and key trial results, which may limit its competitive edge against other treatments.

Mechanism of action

Calcitonin salmon is a calcitonin receptor agonist that mainly influences bone, though it also affects the kidneys and gastrointestinal tract. It has similar actions to mammalian calcitonins but is more potent and has a longer duration of action. Its exact role in bone physiology is not fully understood, but receptors have been found in osteoclasts and osteoblasts.
