Abstract

Disclosed is a Blonanserin-contained oral preparation for treating schizophrenia, using a 2-(4-ethyl-1-piperazinyl)-4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydro-cycloocta[b]pyridine as ingredient, and one or more pharmaceutically acceptable excipients. The preparation method comprises the steps of mixing the 2-(4-ethyl-1-piperazinyl)-4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydro-cycloocta[b]pyridine and the alternative thinner, adhesive, disintegrant, abhesive and lubricant with an appropriate amount of humectants to prepare soft wood, sieving to prepare wet granules, drying the wet granules, sieving and integrating the granules to prepare oral preparation, wherein, the Blonanserin is 0.1-30 per cent of the preparation by weight. The preparation is applicable to administrate 1-2 times per day in 1-2 preparation units each time, and used for controlling the concentration of the 2-(4-ethyl-1-piperazinyl)-4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydro-cycloocta[b]pyridine in the plasma of human body, thus enabling the 2-(4-ethyl-1-piperazinyl)-4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydro-cycloocta[b]pyridine to play a role in treatment.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a compound containing 2-(4-ethyl-1-piperazinyl)-4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydro Oral formulations of aryl octa[b]pyridines and methods for their preparation. Taking this preparation makes 2-(4-ethyl-1-piperazinyl)-4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydroaromatic octane in human plasma [b] Pyridine was maintained at therapeutic levels.
