Rifampicin+Isoniazid+Ethambutol is used in the treatment of tuberculosis.

This is a combination of three medicines: Rifampicin, isoniazid and ethambutol which treat tuberculosis. Rifampicin works by inactivating a bacterial enzyme (RNA-polymerase) which is required by TB bacteria to make essential proteins and to reproduce, while isoniazid prevents these bacteria from forming their own protective covering. Together, they kill the bacteria and eradicate the infection. Ethambutol, on the other hand works by slowing the growth of these bacteria.
