Since 1970, when the lifelong monotherapy with dapsone (DDS) in leprosy could be replaced by short-term combination therapy with rifampicin + isoniazid + protionamide-!-DDS (Isoprodian-RMP), chemotherapeutic research was faced with two problems: (1) to find alternative treatment regimens for cases of intolerance, and (2) to work out forms of therapy allowing a further reduction of the average treatment time of 2 years. The present paper describes the attempts made to find solutions to these problems. With two new combinations, alternatives have become available, and the average treatment time is shortened to 6 months. Both combinations are also effective in tuberculosis.

In the present paper the ‘serial combinations’ (components of the combination offered separately), as used in conventional combination therapy, are compared with the ‘integrated complex combination’ (offered as fixed combinations). So far, three combinations have been worked out on the basis of this concept (RMP + SMZ + TMP + INH; RMP + SMZ + TMP + PTH; RMP + INH + PTH + DDS). They allow successful treatment of almost all mycobacterial infections and diseases (including tuberculosis and leprosy) and a number of infections caused by gram-negative and gram-positive microorganisms and by Pneumocystis carinii.
