Injection-grade ambroxol hydrochloride and solution for inhalation of injection-grade ambroxol hydrochloride

The invention relates to a method for refining injection-grade ambroxol hydrochloride. The method is characterized by comprising the steps of adding oral-taking-grade ambroxol hydrochloride with the proportion smaller than or equal to 20:1 into ethanol water solution with the volume ratio of 5-20%; performing heating to completely dissolve the oral-taking-grade ambroxol hydrochloride; stopping heating and performing cooling to seed out ambroxol hydrochloride; and filtering solvent to obtain crystals and drying the crystals to obtain the injection-grade ambroxol hydrochloride. The invention further relates to ambroxol hydrochloride solution for inhalation prepared by utilizing the prepared injection-grade ambroxol hydrochloride as the raw material. The atomization inhalation solution comprises the ambroxol hydrochloride, a stabilizer, a pH conditioning agent and an osmotic pressure conditioning agent. By means of the scientific preparation adopting the carrier, fewest degradation products of the atomization inhalation preparation can be produced under the high temperature of 121 DEG C for 15 minutes, the atomization inhalation preparation is stable, and the service life of the atomization inhalation preparation is prolonged to 5 years.

Novel inhalation preparation

The invention relates to a novel inhalation preparation, in particular to a preparation suitable for inhalation drug administration of children ranging from 0 to 12 years. After medicine difficult to be dissolved in water and auxiliary materials are mixed, a wet grinding method is adopted for smashing, mixed suspension liquid containing particles with the particle size appropriate is obtained, the particle size is 0.1-7 microns, and preferentially, the particle size is 0.1-5 microns; and further, the preferential particle size is 0.1-3 microns. Solid powder is obtained through a freeze-drying method. Sealing is performed for obtaining the novel inhalation; and before use, the novel inhalation preparation is mixed with liquid suitable for atomization, re-dispersion is performed, and the mixed suspension liquid capable of being used for atomizing inhalation of children is obtained. The preparation is stored and transported in the form of the solid powder, the problem that when a mixed suspension liquid form is adopted, the physical stability and the chemical stability are poor is avoided, the medicine particle size hardly changes, impurity increase is little, and the content hardly changes. Compared with inhalation powder aerosol, the novel inhalation preparation is especially suitable for atomizing medicine administration of children, medicine smaller in particle size can be adopted, and even though under the situations that breathing of an infant is slight and the effective portion deposition rate is low, an ideal medicine effect can also be achieved.

New medical application of compound inhalation preparation of tiotropium bromide and formoterol

The invention provides a new medical application of a compound inhalation preparation of tiotropium bromide and formoterol, namely application to preparation of a medicament for treating lung cancer with chronic obstructive pulmonary disease. The compound inhalation preparation is prepared from tiotropium bromide, formoterol and pharmaceutic adjuvants, wherein the ratio of tiotropium bromide to formoterol is 2.5:1, 2.8:1 or 3:1. Studies show that tiotropium significantly inhibits the growth of lung cancer cells, inhibits the growth of lung cancer transplantable tumors, and produces a strongerbronchodilation effect. Formoterol has no effect on the growth of lung cancer cells and lung cancer transplantable tumors, but can significantly enhance the anti-lung cancer effect and bronchodilationeffect of tiotropium bromide. The compound preparation is administered by airway inhalation, so that the drug concentration of the target organ lung is greatly higher than that of system drug administration, the blood drug concentration and the distribution in other organs are greatly reduced, and the systemic adverse reaction is reduced. The compound inhalation preparation can be applied to treatment of lung cancer with chronic obstructive pulmonary disease.
