Abstract

The invention provides a risperidone film-like preparation, comprising a strip film belt and a treatment effective dose of an active medicine loratadine loaded on the strip film belt, wherein the strip film belt comprises an acidic strip film belt and an alkaline strip film belt, the acidic strip film belt and the alkaline strip film belt are connected to form one body, the acidic strip film belt uses a highly water-soluble polymer film forming material as a main body and contains 1 to 20% of an acidic agent on the basis of the weight of the acidic strip film belt, and the alkaline strip film belt uses the highly water-soluble polymer film forming material as a main body and contains 1 to 20% by weight of an alkaline agent on the basis of the weight of the alkaline strip film belt. In the presence of water, the risperidone film-like preparation provided by the invention becomes an effervescent film, generates considerable bubbles, paralyzes olfactory sensation of people so as to mask odor and is accelerated in dissolving-out.

Description

technical field [0001] The invention relates to a risperidone preparation, in particular to a drug film preparation containing risperidone. Background technique [0002] Risperidone is a derivative of benzisoxazole, which is a new generation of antipsychotics. It is a selective monoaminergic antagonist with unique properties, unlike the serotonergic 5-HT 2 D receptors and dopamine 2 The receptor has a high affinity. For the treatment of acute and chronic schizophrenia and the obvious positive symptoms (such as hallucinations, hallucinations, disorganized thinking, hostility, suspicion) and obvious negative symptoms (such as unresponsiveness, emotional and social apathy, few words). It may also reduce affective symptoms (eg, depression, guilt, anxiety) associated with schizophrenia. For patients who are effective in the acute phase of treatment, their clinical efficacy can continue to be exerted in the maintenance phase of treatment. The risperidone is prepared into a f...
