Abstract

The invention relates to an octreotide acetate tablet and a preparation method thereof. The octreotide acetate tablet is prepared from octreotide acetate nanoparticle and pharmaceutically acceptable tablet auxiliary materials, wherein the octreotide acetate nanoparticle comprises octreotide acetate, an enzyme inhibitor and a high polymer material. The octreotide acetate tablet provided by the invention is capable of significantly prolonging the medicine action time, and is convenient to medicate in comparison with an injection dosage form; the compliance of patients is improved; and meanwhile, the octreotide acetate tablet wraps a high-molecular compound and exists in a solid form, so that the quality guarantee period of the octreotide acetate is significantly prolonged.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to octreotide acetate tablets and a preparation method thereof. Background technique [0002] Octreotide acetate is a synthetic octapeptide compound, which is a tetradeceptide human somatostatin analog. The pharmacological action of octreotide is similar to that of natural hormones, but its inhibitory effect on growth hormone, glucagon and insulin is stronger. Similar to somatostatin, octreotide also inhibits the LH response to GnRH, reduces splanchnic blood flow, and inhibits the secretion of 5-HT, gastrin, vasoactive intestinal peptide, chymotrypsin, motilin, and glucagon. [0003] Because octreotide acetate is a polypeptide preparation, oral absorption of the drug is poor, while subcutaneous and intravenous administration can be rapidly and completely absorbed. Octreotide acetate injection, clinical use can be intravenous injection, subcutaneous injection, intravenous...
