Abstract

The invention relates to liquor containing indacaterol maleate. The content of the indacaterol maleate is 2.0 mug / ml-15 mug / ml; while being used, content can be released in the forms of mists by virtue of pressure of a manual pump, ultrasonic spraying, an air compressor, and the like, and can be used for lung inhalation administration. The invention specifically relates to inhalation spray containing the indacaterol maleate.

Description

field of invention [0001] The invention belongs to the field of medicines, and in particular relates to a solution containing indacaterol maleate. When used, the contents are released in the form of mist by means of manual pumps, ultrasonic sprays, air compressors, etc., and are used for lungs. Preparations for inhalation. Background of the invention [0002] Chronic obstructive pulmonary disease (COPD) is a serious lung disease that makes breathing difficult. Symptoms can include shortness of breath, chronic cough, and excessive phlegm.
