Abstract

The invention discloses a method for preparing fluticasone propionate suspension for inhalation. Sterile fluticasone propionate suspension is prepared in a way of treating fluticasone propionate and accessories respectively. A solution is prepared from the accessories, and is filtered and sterilized through a microporous filter membrane, and microbial load control over each accessory is not required, so that the cost is lowered.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to medicines for treating respiratory diseases, and more specifically to a preparation method of fluticasone propionate suspension for inhalation. Background technique [0002] Delivery of drugs to the lungs through oral inhalation is an important drug delivery method for the treatment of respiratory diseases (such as asthma, chronic obstructive pulmonary disease, etc.). Compared with systemic drug delivery (such as oral administration, injection, etc.), inhalation Drugs can be delivered directly to the site of action, avoiding the side effects of systemic administration. [0003] Existing inhalation drug products include aerosol, powder aerosol and nebulized inhalation solution. Among them, aerosol and powder aerosol use specific drug delivery devices, and the drug delivery process requires the patient to inhale the drug and operate the device. Coordination between these drugs can effectiv...
