Disclosed are a slow release pasireotide microsphere and a preparation method thereof. The microsphere is prepared using pasireotide as an active ingredient, and a microsphere support polymer, a protecting agent, a surfactant and a suspending agent. The microsphere support polymer is selected from polylactic-co-glycolic acids (PLGA). The suspending agent is selected from one or a combination of any two or more of tragacanth, gum arabic, carbomer and sodium alginate. The preparation method of the microsphere is a multiple emulsion method. Addition of the suspending agent allows for a release time of the pasireotide microsphere of up to 28 days. |
