Methodology: Patients who had previously been treated for pulmonary tuberculosis for at least 1 month duration and is a failure, relapse or defaulter case presenting in Fauji Foundation Hospital Rawalpindi, both indoor and outdoor were enrolled in the study. Patients were randomized by lottery method to either of the two treatment arms; WHO retreatment regimen or six drug formulations. Clinical features were documented, baseline investigations, AFB smear, Gene Xpert and AFB Culture were sent. Drugs were given on once daily dosage.

There were 33 (6.7) male and 457 (93.3) female patients whereas the frequency of early response of WHO retreatment regimen with the six drugs regimen in pulmonary tuberculosis retreatment category patients was 187 (76.3) and 211 (86.1) respectively which was statistically significant (p-value 0.000).
