Several anti-tuberculosis regimes can be administered with effective antiretroviral therapy in HIV infected person.
The use of Rifampicin to treat active TB is specifically contraindicated for patients taking any of the Pis or NNRTIS, and drugs regimens that include Rifabutin were suggested as preferable alternatives.
New data indicate that Rifampicin can be used for the treatment of active TB in situations where the patient is taking NNRTI (Efavirenz) and two NRTI, or PI (Ritonavir) and one or more NNRTIS or a combination of two PI (Ritonavir and Saquanavir).
Rifabutin originally recommended for use is too expensive and toxic.
