Abstract

The invention provides Asenapine tablets and a preparation method thereof. The tablets comprise the following components in percentages by weight: 10-50% of Asenapine, 30-80% of a filler, 3-20% of a disintegrating agent, 0.5-1% of lubricant, and 0.2-2.5% of a flavouring. The preparation method comprises the following steps: micronization is carried out for Asenapine and the filler, and the particle size is controlled at 0.5-20[mu]m; the fine powder obtained in the last step and partial disintegrating agent are prepared into a soft material with an ethanol water, and granulation is carried out with 24 mesh sieve; prepared fine granules are dried at 50-70 DEG C, and granulation is carried out with 20 mesh sieve; the residual disintegrating agent, the flavouring and the lubricant are added into dried particles in order, total mixing is carried out twice, one mixing is carried out before the lubricant is added, the other mixing is carried out after the lubricant is added, till intermediate detection is qualified, the tablets are compressed, and the product is prepared. Asenapine tablets are common tablets with coating or without coating, the product is a novel atypical antipsychotic drug; the drug has the advantages of fast drug absorption, high bioavailability, and usage convenience.

Description

technical field [0001] The present invention relates to a novel atypical antipsychotic preparation, specifically a tablet, including coated or uncoated ordinary tablet, chewable tablet and orally disintegrating tablet. Background technique [0002] Asenapine is a new type of atypical antipsychotic drug for the treatment of adults with acute schizophrenia and acute mania or mixed episodes with bipolar I disorder. Its exact mechanism is still not very clear, it may be related to the antagonism of dopamine D2 and 5-hydroxytryptamine 2A (5-HT2A). Asenapine has high affinity to various dopamine, serotonin, norepinephrine receptor and histamine receptor subtypes, N-methyl-D-aspartic acid (NMDA) and α-amino- 3-Hydroxy-5-methyl-4-isoxazolepropionic acid (NMPA) receptors also have affinity. [0003] Asenapine sublingual tablet was approved for marketing by FDA on August 14, 2009, and was approved for marketing by EU on November 27, 2009. The trade name is Saphris. The bioavailabil...
