Problems solved by technology

[0005] The currently marketed inhalation preparation of umeclidinium bromide is a powder aerosol. The powder aerosol needs to rely on the patient's large inspiratory flow rate to start the nebulization. The patient cannot achieve drug delivery under normal breathing conditions, so it is not suitable for children and the elderly. and other patients with difficulty breathing on their own initiative
At present, there is no inhalation solution preparation on the market. Chinese patent CN110292559A discloses umeclidinium bromide atomized inhalation solution, and its prescription composition includes umeclidinium bromide, surfactant, isotonic regulator, metal ion complexing agent, pH buffer, pH adjuster, water; it is recorded in the patent that the osmotic regulator can be selected from mannitol, and mannitol is an activator of bronchospasm, which can easily cause bronchospasm and cause adverse reactions, and the metal ion complexing agent can be selected from ethylenediaminetetraacetic acid Disodium, disodium edetate is an important complexing agent, which is used to complex metal ions and separate metals. It can also be used as an antioxidant synergist, stabilizer and softener. Stimulates the upper respiratory tract

Abstract

The invention provides an inhalation umeclidinium bromide solution, a preparation method and application thereof, the inhalation solution comprises an active substance, a solvent and auxiliary materials, the single dose specification of the inhalation solution is 1-5ml, and the active substance in the single dose specification is 20-100 micrograms of umeclidinium bromide; the solvent is sterile injection water; the auxiliary materials comprise an isoosmotic adjusting agent and a pH adjusting agent; the adding amount of the isoosmotic adjusting agent is such that the inhalation solution has a weight gram molecule osmotic concentration of 240-400mOsmol / kg; the pH regulator is added so that the pH value of the inhalation solution preparation is 4.0-6.0. The device for combining the ullidinium bromide solution for inhalation with an atomized aerosol can provide a medicine dosage form of the ullidinium bromide for inhalation, which is convenient to use, safe, effective and good in stability, and an administration system.

Description

technical field [0001] The invention belongs to the field of pharmacy, and in particular relates to a umeclidinium bromide solution for inhalation, a preparation method and application thereof. Background technique [0002] Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease characterized by incompletely reversible airflow limitation, with a large number of patients and a high mortality rate. According to the World Health Organization (WHO), there are currently 600 million people suffering from this disease worldwide, and it will become the third leading cause of death in the world by 2020. [0003] According to the "2013 Chinese Medical Association Guidelines for the Diagnosis and Treatment of Chronic Obstructive Pulmonary Disease", the treatment drugs include: bronchodilators, glucocorticoids, phosphodiesterase-4 (PDE-4) and other drugs. Bronchodilators are the main treatment for controlling COPD symptoms. They can relax bronchial smooth muscle, ...
