Problems solved by technology

[0006] At present, the dosage forms of terbutaline sulfate in the domestic and foreign markets include oral and spray inhalation. The oral dosage forms include tablets and dropping pills. Due to the characteristics of the tablet preparation technology, the disintegration time of such oral preparations is long. , slow onset and low bioavailability, thus affecting the full play of the drug effect; compared with tablets, the disintegration time and bioavailability of drop pills are improved, and they also have the disadvantages of oral dosage forms

Abstract

The invention relates to a preparation method of a terbutaline sulfate solution for inhalation. The terbutaline sulfate solution contains a main ingredient, a stabilizer, an iso-osmolar agent, a pH regulator and injection water, and pH value of the terbutaline sulfate solution is 3.0-5.0. The terbutaline sulfate solution has good effect on improving lung functions.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a preparation method of a terbutaline sulfate solution for inhalation for preventing and alleviating respiratory diseases. Background technique [0002] Asthma is a common multiple respiratory disease. Asthma has a large number of patients in my country, and it is relatively common in children. It is a disease that seriously endangers the physical and mental health of the human body and reduces the quality of life. The disease is difficult to be cured, and clinically, conservative treatment is the main method. In recent years, with the aggravation of air quality pollution and the weakening of people's exercise ability, the incidence of asthma is gradually increasing, so the treatment of asthma is urgent. [0003] Terbutaline sulfate is a drug mainly used for the treatment of bronchospasm in bronchial asthma, asthmatic bronchitis and chronic obstructive pulmonary di...
