[Tuberculosis therapy 1990].

The goal of modern therapy of tuberculosis is the rapid killing of all bacilli with potent and relatively atoxic antituberculous drugs. Currently available first-line drug regimens are highly effective, well tolerated and relatively easily administered. The addition of Pyrazinamide enables the minimum treatment period to be shortened to six months (two months Isoniazid, Rifampin, Pyrazinamide and four months Isoniazid, Rifampicin). This article reviews the available first-line drugs in treatment of tuberculosis, the rationale for the recommended chemotherapeutic regimens, the follow-up of treated patients and special issues related to the treatment of extrapulmonary tuberculosis and tuberculosis in HIV-infected patients.
