The invention discloses an umeclidinium
bromide atomization
inhalation solution and a preparation method thereof. The umeclidinium
bromide atomization
inhalation solution per 1,000 ml contains 0.01-0.5 g of umeclidinium
bromide, 0.01-0.5 g of a surfactant, 1-100 g of an isoosmotic adjusting agent, 0.1-1 g of a
metal ion complexing agent and 0.1-20 g of a
pH buffering agent, a pH adjusting agent adjusting the pH of the
system to 4.0-7.0 and the
balance water, and the total amount is 100 ml. According to the umeclidinium bromide atomization
inhalation solution and the preparation method thereof,not only can the
potential harm of a
lactose carrier in
dry powder inhalation be avoided, but also the conveyed dosage is accurate and controllable, the requirement for the
breathing air flow is low,and the compliance is good. The preparation method is simple to implement, the required equipment is simple, and the
sterility requirement of the product can be met. According to the umeclidinium bromide atomization
inhalation solution, the surfactant is added, and therefore side effects generated after the atomization
inhalation solution is inhaled by a normal person in the atomization process are reduced, and the
utilization rate of the
medicine is also increased.
