| Chemical Formula | C145H240N44O48S2 |
| Isoelectric Point | 8.86 |
| Hydrophobicity | -0.537 |
| Melting point | NA |
| Half-life | 0.83-1.33 hours |
| Description | Synthetic peptide of 32 residues, formulated as a nasal spray. |
| Indication/Disease | Used for the treatment of post-menopausal osteoporosis. |
| Pharmacodynamics | Calcitonin inhibits bone removal by osteoclasts and promotes bone formation by osteoblasts, leading to a net increase in bone mass. Calcitonin also reduces plasma calcium levels and enhances secretion of ions in the kidney. |
| Mechanism of Action | Calcitonin binds to the calcitonin receptor, found mainly in osteoclasts which then enhances the production of vitamin D producing enzymes (25-hydroxyvitamine D-24-hydroxylase), leading to greater calcium retention and enhanced bone density. Binding of calcitonin to its receptor also activates adenylyl cyclase and the phosphatidyl-inositol-calcium pathway. |
| Toxicity | It is devoid of embryotoxic, teratogenic and mutagenic potential. |
| Metabolism | Primarily and almost exclusively degraded in the kidneys, forming pharmacologically inactive fragments of the molecule. |
| Absorption | Rapidly absorbed and eliminated. Bioavailability is high following subcutaneous and intramuscular injection in humans and similar for the two routes of administration (71% and 66%, respectively). |
| 0.15 to 0.3 L/kg |
| Clearance | Studies with injectable calcitonin show increase in the excretion of filtered calcium, phosphate, and sodium by decreasing their tubular reabsorption in the kidney. |
