简要总结
The purpose of this study is to determine whether one or two four month regimens of tuberculosis treatment are as effective as a standard six month regimen for treatment of pulmonary tuberculosis(TB).All three regimens are administered daily , seven days each week with direct observation of each dose by a health care worker atleast five of the seven days each week.
The standard six month regimen is two months of isoniazid, rifampin, ethambutol and pyrazinamide followed by four months of isoniazid and rifampin.
The first short regimen is a singly substitution of rifapentine for rifampin: two month so isonisazid ,rifapentine , ethambutol and pyrazinamide followed by two****months of isoniazid and rifapentine.
The second short regimen is a doublesubstitution of rifapentine for rifampin and moxifloxacin forethambutol twomonths of isoniazid, rifapentine, moxifloxacin and pyrazinamide,followed by twomonths of isoniazid and rifapentine and moxifloxacin
