Abstract

The invention belongs to the field of the pharmaceutics technology, and particularly relates to a honeysuckle flower and radix scutellariae solution preparation for inhalation and a preparing method thereof. The honeysuckle flower and radix scutellariae solution preparation for inhalation comprises a first extract, a second extract, an auxiliary and a solvent. The first extract is prepared by extracting honeysuckle flower, leaves of panax notoginseng and houttuynia cordata, and the second extract is prepared by extracting radix scutellariae. The honeysuckle flower and radix scutellariae solution preparation for inhalation is safe, effective, high in bioavailability, small in use dosage, rapid in effect, good in treatment effect and free of other toxic and side effects; the preparation is given to a patient through atomized inhalation, the medicine is directly transmitted to a respiratory tract, absorption is rapid, and acting is rapid; the first-pass effect and gastrointestinal tract degradation can be avoided, the medicine concentration of a focus part is increased, the dosage of administration is reduced, the distribution of the medicine in other tissue is reduced, and side effects of the medicine are reduced.

Description

technical field [0001] The invention belongs to the field of pharmacy, and in particular relates to a silver bain solution preparation for inhalation and a preparation method thereof. Background technique [0002] The "Yinqin" prescription is composed of four traditional Chinese medicines: honeysuckle, scutellaria, notoginseng, and houttuynia cordata, which have the effects of clearing away heat and detoxification, and clearing away wind-heat.
