How to use

In Vitro:

Pasireotide effectively inhibits the growth hormone releasing hormone (GHRH) induced growth hormone (GH) release in primary cultures of rat pituitary cells with an IC50 of 0.4±0.1 nM.

In Vivo:

Pasireotide potently suppressess GH secretion in rats. The ED50 values determined at 1 and 6 h after injection of pasireotide indicates its very long duration of action in vivo. In the rat, pasireotide strongly decreases IGF-1 plasma levels, with the efficacy being markedly enhanced compared with the effects elicited by SMS 201-995 after 7 days of treatment. Furthermore, in rats, dogs, and rhesus monkeys, pasireotide potently and dose-dependently decreases IGF-1 levels for prolonged periods of time without desensitization[1]. Pasireotide (160 mg/kg/month, s.c.) decreases serum insulin levels and increases serum glucose levels, reduces PNET tumor size, and demonstrates a reduction in tumor activity on PET/CT scan in Pdx1-Cre; Men1 floxed/floxed conditional knockout mice. Pasireotide (50 μg/kg) inhibits arthritic joint swelling in a dose-dependent manner, strongly inhibits joint swelling during the acute phase of AIA. Pasireotide- and octreotide-treated mice show significantly increased mechanical thresholds on the inflamed side. Pasireotide potently decreases secondary hyperalgesia to mechanical and thermal stimuli. Mechanical thresholds in the pasireotide-treated mice are significantly higher than those in the saline-treated or octreotide-treated animals.
