Abstract

The invention discloses a preparation method of a cariprazine-hydrophilic material blend solid preparation. The solid preparation comprises a cariprazine-hydrophilic material blend and other pharmaceutically acceptable ingredients, wherein the cariprazine-hydrophilic material blend effectively improves the dissolution speed of cariprazine in the solid preparation, is favorable for improving the bioavailability of a drug, and is used to treat a patient with schizophrenia and diphasic I type related psychlampsia or mixed episode, and the process is simple and convenient and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a cariprazine dissolution solid preparation and a preparation method thereof. Background technique [0002] The chemical name of cariprazine (CARIPRAZINE) is N'-[trans-4-[2-[4-(2,3-dichlorophenyl)-1-piperazinyl]ethyl]cyclohexyl]-N , N-dimethylurea, a once-daily oral atypical antipsychotic drug, can partially stimulate D3 / D2 receptors, which preferentially bind to D3 receptors. The mechanism for the treatment of schizophrenia and bipolar disorder is not yet clear, and its therapeutic effect may be through partially activating D2 receptors and 5-hydroxytryptamine 1A receptors, and antagonizing 5-HT2A receptors. [0003] Cariprazine is an atypical antipsychotic first developed by FOREST RES INST INC for the treatment of acute manic or mixed episodes associated with schizophrenia and bipolar I disorder. New data from a phase 3 clinical trial of carip...
