Octreotide Acetate Injection, a cyclic octapeptide prepared as a clear sterile solution of octreotide, acetate salt, in a buffered lactic acid solution for administration by deep subcutaneous or intravenous injection. Octreotide acetate, known chemically as L-Cysteinamide, D-phenylalanyl-L-cysteinyl-L-phenylalanyl-D-tryptophyl-L-lysyl-L-threonyl-N-[2-hydroxy-1-(hydroxymethyl)propyl]-,cyclic (2 → 7)-disulfide; [R-(R*, R*)] acetate salt, is a long-acting octapeptide with pharmacologic actions mimicking those of the natural hormone somatostatin. Octreotide Acetate Injection is available as sterile 1-mL vials in 3 strengths, containing 50 mcg, 100 mcg, or 500 mcg octreotide (as acetate). Each vial also contains glacial acetic acid, USP (2 mg), mannitol, USP (45 mg), sodium acetate trihydrate, USP (2 mg), water for injection, USP (quantity sufficient to 1 mL). Glacial acetic acid, USP and sodium acetate trihydrate, USP are added to provide a buffered solution, pH to 4.2 ± 0.5. The molecular weight of octreotide acetate is 1019.3 g/mol (free peptide, C 49 H 66 N 10 O 10 S 2 ) and its amino acid sequence is: Structural image
