摘要

FIELD: medicine, pharmaceutics.SUBSTANCE: claim describes prolonged release formulations containing an active ingredient presented by octreotide or its pharmaceutically acceptable salt and three various linear polymers of poly(lactide-co-glycolic acid) (PLGA). The first PLGA has the lactide:glycolic acid relation of 65:35; the second PLGA has the lactide:glycolic acid relation of 75:25; the third PLGA has the lactide:glycolic acid relation of 85:15. The octrotide composition containing three various linear polymers of PLGA is characterized by the plasma octreotide concentration of low variability over the period of time making more than three months.EFFECT: composition is applicable for the prolonged supporting therapy of the patients suffering acromegalia and for treating diarrhoea and congestions associated with malignant carcinoids and tumours producing vasoactive intestinal peptides (VIPoma-like tumours).18 cl, 4 tbl, 5 ex
