Abstract

The invention relates to an antitubercular pharmaceutical composition containing balloonflower root extract, which is prepared from the components of 0.1-100 parts of balloonflower root extract by weight and 1 part of antitubercular drug by weight through the steps as follows: extracting the balloonflower root extract for three times by water or extracting the balloonflower root extract for threetimes by 40-95% ethanol at the temperature of 90 DEG C, and concentrating, wherein the weight measurement ratio of the balloonflower root extract to the water is 1:(6-10), and the weight measurement ratio of the balloonflower root extract to the ethanol is 1:(5-15). The pharmaceutical composition in the invention has the functions of enriching the antitubercular drugs in lung tissues and improving the potency of the antitubercular drugs for curing phthisis as compared with single antitubercular drugs, and simultaneously has the positive effects such as reducing the liver injury caused by the antitubercular drugs and the like. By utilizing he pharmaceutical composition, the phthisis therapeutic window of the antitubercular drugs can be amplified, and the capability of effectively killing tubercle bacillus is enhanced, thereby increasing the potency, shortening the treatment cycle and lowering the possibility of tolerance of tubercle bacillus.
