用于治疗哮喘的植物提取物吸入气雾剂及制备方法技术

本发明专利技术提供了一种用于治疗哮喘的植物提取物吸入气雾剂及制备方法，所述的用于治疗哮喘的植物提取物，是以包括如下重量份数的原料制备的：椒目５～２０份，艾叶１２－８５份，细辛５－３５份，麻黄５－３５份。本发明专利技术的技术特点在于：首次将亲脂性的植物提取物与极性相对较大的氢氟烷烃混合制备了一类植物提取物定量吸入气雾剂。药物喷射出来后，与水接触后可以变成很小的乳粒，从而迅速吸收，发挥药效。所制备气雾剂在降低药物刺激性和毒性的同时提高药物吸收速率和透粘膜能力，进而提高药物的生物利用度，增强药物的疗效，改善患者用药的顺应性。

Plant extract inhalation aerosol for treating asthma and method for preparing the same

The present invention provides an inhalation aerosol and preparation method of plant extracts for the treatment of asthma, the plant extract for treating asthma, is to include the following parts by weight of raw material preparation: JiaoMu 5 ~ 20, leaves 12 - 85, 5 - 35 copies of Ephedra Asarum. A 5 - 35. The invention is characterized in that a kind of plant extract quantitative inhalation aerosol is prepared for the first time by mixing lipophilic plant extracts with hydrogen hydrocarbon with relatively large polarity. When the medicine is sprayed out, it can be changed into small milk granules after contact with water so as to absorb quickly and exert its efficacy. The increase rate of drug absorption and transmucosal ability in reduced irritation and toxicity and aerosol preparation, and then improve the bioavailability of drugs, enhance the efficacy of drugs, improve patient medication compliance.
