Octastatin (RC-160, vapreotide INN) is a somatostatin analogue being developed for use in oncological, enterologic and neuroendocrine applications. The pharmaceutical form is a freeze-dried preparation for parenteral injection use. Three dosage forms containing 0.5, 1.5 and 15 mg of vapreotide base have been investigated. Various freeze-drying conditions, stabilizing agents, membranes for sterile filtration and heating procedures have been examined. The formulation with glutamic acid-sodium glutamate buffer as a stabilizing agent, the type of membrane for filtration and the freeze-drying procedure have been found appropriate for subsequent industrial production. No evident degradation was observed either after manufacturing, or after a three-week accelerated stability study at 50 degrees C and 70% relative humidity.

Octastatin (vapreotide INN) is a somatostatin analogue being developed in gastro-enterologic, neuroendocrine and oncologic applications. The pharmaceutical form is a freeze-dried preparation for parental injection use. This study was intended to evaluate the stability of the freeze-dried products and to determine the optimally stable formulation. Two types of stabilizing agents (lactose and glutamic acid/sodium glutamate buffer) and three dosage forms (0.5, 1.5, 15 mg of vapreotide base) were investigated. The peptide content and chemical stability of cakes stored at 50 degrees C and 70% relative humidity were determined by HPLC and the regression analysis parameters calculated. Results indicate that the formulation with glutamate buffer is appropriate for long term storage.
