Abstract

The present invention provides a medicine component containing a tobramycin inhalation solution and an application thereof. The medicine component comprises: (a) the tobramycin inhalation solution; and (b) the vibrating screen atomizer used in cooperation with the tobramycin inhalation solution. The central area of a metal mesh of the vibrating screen atomizer has 1400-1800 micropores. The fogdrop particle size of the tobramycin inhalation solution is as follows: D10 ranges from 0.5 [mu]m to 2.5 [mu]m, D50 ranges from 2.0 [mu]m to 4.2 [mu]m, and D90 ranges from 6.0 [mu]m to 9.0 [mu]m. The mass percentage of the particles with the aerodynamic particle size smaller than 5.39 [mu]m in the tobramycin inhalation solution is not smaller than 45%. The medicine component has a remarkable effect on clinically treating bronchiectasia.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a pharmaceutical assembly containing tobramycin inhalation solution and its application. Background technique [0002] Aminoglycoside antibiotics are named because their molecular structure has an aminocycloalcohol and one or more aminosugar molecules, which are connected by glycosidic bonds to form glycosides. Most of them are polar compounds, which are not easily absorbed by the gastrointestinal tract. Administration by injection. Adverse events such as ototoxicity and nephrotoxicity usually occur clinically due to injection administration. Ototoxicity can be divided into: ① vestibular dysfunction, more common in streptomycin, kanamycin, gentamicin, tobramycin, the incidence rate after medication is kanamycin > streptomycin > gentamicin Tobramycin > tobramycin; ② cochlear nerve damage, which is more common in kanamycin, amikacin, sisomicin, gentamicin, etc., and the...
