Description

technical field

[0001] The invention belongs to the technical field of medicine, and more specifically, the invention discloses an injection and a preparation method thereof. Background technique

[0002] Octreotide is a synthetic octapeptide derivative of natural somatostatin, its chemical name is D-phenylalanyl-L-cysteinyl-L-phenylalanyl-D-tryptophanyl-L-lysine Acyl-L-threonyl-L-cysteinyl-L-threoninol ring 2→7) disulfide, its pharmacological effect is similar to that of somatostatin but the duration of action is longer. It inhibits pathological increases in secretion of growth hormone (GH) and peptides of the gastroenteropancreatic (GEP) endocrine system.

[0003] In animals, octreotide is more potent than somatostatin at inhibiting the release of growth hormone, glucagon, and insulin, and is more selective for growth hormone and glucagon.

[0004] Octreotide exhibits the following inhibitory effects on healthy subjects: inhibition of growth hormone release induced by ar...

Examples

Embodiment 1

[0013] Preparation of Octreotide Acetate Injection

[0014] Prescription (calculated in 1000 sticks):
