  The recommended treatment of new-onset pulmonary tuberculosis, as of 2010, is six months of a combination of antibiotics containing rifampicin, isoniazid, pyrazinamide, and ethambutol for the first two months, and only rifampicin and isoniazid for the last four months. Where resistance to isoniazid is high, ethambutol may be added for the last four months as an alternative. Treatment with anti-TB drugs for at least 6 months results in higher success rates when compared with treatment less than 6 months, even though the difference is small. Shorter treatment regimen may be recommended for those with compliance issues. There is also no evidence to support shorter anti-tuberculosis treatment regimens when compared to a 6-month treatment regimen. However, results presented in 2020 from an international, randomized, controlled clinical trial indicate that a four-month daily treatment regimen containing high-dose, or "optimized", rifapentine with moxifloxacin (2PHZM/2PHM) is as safe and effective as the existing standard six-month daily regimen at curing drug-susceptible tuberculosis (TB) disease.
