Description
Pasireotide is a synthetic long-acting cyclic hexapeptide with somatostatin-like activity. It is marketed as a diaspartate salt called Signifor, which is used in the treatment of Cushing's disease.
Indication
For the treatment of Cushing’s disease, specifically for those patients whom pituitary surgery has not been curative or is not an option.
Mechanism of Action
Pasireotide activates a broad spectrum of somatostatin receptors, exhbiting a much higher binding affinity for somatostatin receptors 1, 3, and 5 than octreotide in vitro, as well as a comparable binding affinity for somatostatin receptor 2. The binding and activation of the somatostatin receptors causes inhibition of ACTH secretion and results in reduced cortisol secretion in Cushing's disease patients. Also this agent is more potent than somatostatin in inhibiting the release of human growth hormone (HGH), glucagon, and insulin.
