Signifor® is an analogue of somatostatin that promotes reduced levels of cortisol secretion in Cushing's disease patients.
- 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.
Target Actions Organism USomatostatin receptor type 1 Not Available Humans USomatostatin receptor type 2 Not Available Humans USomatostatin receptor type 3 Not Available Humans USomatostatin receptor type 5 Not Available Humans - Absorption
The peak plasma concentration of pasireotide occurs in 0.25-0.5 hours. After administration of single and multiple doses, there is dose-proportionoal increases in Cmax and AUC.
- Volume of distribution
Pasireotide is widely distributed and has a volume of distribution of >100L.
- Protein binding
Plasma protein binding is 88%.
- Metabolism
Metabolism is minimal.
- Route of elimination
Pasireotide is eliminated mostly by hepatic clearance (biliary excretion)(about 48%) with some minor renal clearance (about 7.63%).
- Half-life
The half-life is 12 hours.
- Clearance
The clearance in healthy patient is ~7.6 L/h and in Cushing’s disease patients is ~3.8 L/h.
- Adverse Effects
