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 IV 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 5 mL multi-dose vials in 2 strengths, containing 200 mcg or 1000 mcg octreotide (as acetate). Each mL of multi-dose vials also contains lactic acid, USP (3.4 mg), mannitol, USP (45 mg), phenol, USP (5.0 mg), sodium bicarbonate, USP (quantity sufficient to pH 4.2 ± 0.3), water for injection, USP (quantity sufficient to 1 mL). Lactic acid and sodium bicarbonate are added to provide a buffered solution, pH to 4.2 ± 0.3. 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: octreotide-spl-structure
