Problems solved by technology

The acidic agent and alkaline agent in the effervescent agent react during the pulping process and cannot remain in the film at the same time
2) When preparing the compound film, due to the different physical and chemical properties of the active ingredients in the compound, the suitable prescription and process are different, and sometimes they will affect each other
For example, in a compound composed of A and B, acidic auxiliary materials can enhance the stability of substance A, but affect the solubility of substance B, making it difficult for B to disperse evenly during the pulping process

Abstract

The invention provides a Montelukast sodium 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 acidic strip film belts and alkaline strip film belts, the acidic strip film belts and the alkaline strip film belts are connected to form one body and alternately arranged, each 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 each 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 Montelukast sodium 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 montelukast sodium preparation, in particular to a drug film preparation containing montelukast sodium. Background technique [0002] Montelukast sodium is a potent selective leukotriene D receptor antagonist, which can selectively inhibit the activity of leukotriene polypeptides in airway smooth muscle, block the combination of leukotriene and receptors, and effectively prevent and Inhibit the increase of vascular permeability, airway eosinophil infiltration and bronchospasm caused by leukotrienes, reduce the cellular and non-cellular inflammatory substances in the airway caused by allergen stimulation, reduce airway inflammation, and inhibit Allergen-provoked airway hyperresponsiveness, thereby controlling asthma symptoms. It is prepared into a drug film preparation, which does not need to be taken with water and dissolves on the tongue. It is especially suitable for children, improves patient compliance, and is welcomed b...
