Sandostatin 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. Sandostatin Injection is available as sterile 1-mL ampuls in 3 strengths, containing 50 mcg, 100 mcg, or 500 mcg octreotide (as acetate). Each ampul also contains lactic acid, USP (3.4 mg), mannitol, USP (45 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 acetate amino acid sequence
