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 (IV) injection. Octreotide acetate, known chemically as D-Phenylalanyl-L-cysteinyl-L-phenylalanyl-D-tryptophyl-L-lysyl-L-threonyl-N-[(1R,2R)-2-hydroxy-1-(hydroxymethyl)propyl]-L-cysteinamidecyclic(2--7)-disulfide 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 syringes in 3 strengths, with each mL containing 50 mcg, 100 mcg, or 500 mcg octreotide (as acetate) and also contains L-lactic acid 3 mg, sodium chloride 7 mg, sodium hydroxide to adjust pH, and water for injection, q.s. L-Lactic acid and sodium hydroxide are added to provide a buffered solution, pH range 3.9 to 4.5. 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: Octreotide Acetate Amino Acid Sequence
