Octreotide is the acetate salt of a cyclic octapeptide. It is a long-acting octapeptide with pharmacologic properties mimicking those of the natural hormone somatostatin. Octreotide is known chemically as L-Cysteinamide, D-phenylalanyl-L-cysteinyl-L-phenylalanyl-D-tryptophyl-L-lysyl-L-threonyl-N-[2-hydroxy-1-(hydroxy-methyl) propyl]-, cyclic (2→7)-disulfide; [R-(R*,R*)]. The molecular weight of octreotide 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 for injectable suspension is available in a single-dose vial containing the sterile drug product, which when mixed with diluent, becomes a suspension that is given as a monthly intragluteal injection. The octreotide is uniformly distributed within the microspheres which are made of a biodegradable glucose star polymer, D,L-lactic and glycolic acids copolymer. Sterile mannitol is added to the microspheres to improve suspendability. Octreotide acetate for injectable suspension is available as: sterile 8-mL single-dose vials in 3 strengths delivering 10 mg, 20 mg, or 30 mg octreotide-free peptide. Each single-dose vial of octreotide acetate for injectable suspension delivers: Name of Ingredient 10 mg 20 mg 30 mg octreotide acetate, USP 11.2 mg * 22.4 mg * 33.6 mg * D,L-lactic and glycolic acids copolymer 188.8 mg 377.6 mg 566.4 mg mannitol 41.0 mg 81.9 mg 122.9 mg *Equivalent to 10 mg, 20 mg, or 30 mg octreotide, respectively. Each prefilled syringe of diluent contains: carboxymethylcellulose sodium 14 mg mannitol 12 mg poloxamer 188 4 mg water for injection q.s. to 2 mL 1
