[Controlled clinical study on efficacy of fixed-dose compounds rifater/rifinah in antituberculous chemotherapy]
Objective:
To assess antituberculous efficacy, patients' compliance and application perspective of fixed-dose compounds rifater/rifinah in China.
Method:
Three hundred eight new smear positive pulmonary tuberculosis patients were randomly allocated with a ratio of 2 to 1 into treatment group (227 cases, receiving 2RIFATER/4RIFINAH regimen) and controls (81 cases, 2HRZ/4HR) for observation.
Result:
The sputum negative conversion rates at the 2nd month in the treatment group and the controls were 91.2% and 86.4% respectively, and at the end of the chemotherapy 98.7% and 97.5%. Chest radiography showed remarkable improvement. The resolution of pulmonary lesions in the treatment group and the controls accounted for 95.2% and 93.8% respectively, with cavity closure rates of 68.6% in the treatment group and 67.9% in the controls. The drug adverse reaction rates were 8.9% in both groups, and the default rates were 4.3% and 7.8% respectively.
Conclusion:
Fixed-dose compounds rifater/rifinah show excellent therapeutic efficacy, safety and compliance in antituberculous chemotherapy, which could be recommended for wider use in tuberculosis control in China.
