Trac-4 Tablet is used to treat tuberculosis. Tuberculosis is an infectious disease that mainly affects the lungs, but it can also spread to other body parts such as kidneys, brain, spine and bone marrow. Trac-4 Tablet does not work against infections caused by the virus, including cold and flu.

Trac-4 Tablet is a combination of four anti-tuberculosis drugs: Rifampicin, isoniazid, pyrazinamide and ethambutol. Isoniazid prevents the formation of the bacterial cell wall. At the same time, rifampicin inactivates a bacterial enzyme (RNA-polymerase), which is required by TB bacteria (Mycobacterium tuberculosis) to make essential proteins and to reproduce. Ethambutol and pyrazinamide work by slowing the growth of bacteria. Altogether, they kill the bacteria and treat the infection.
