Pyrazinamide is a drug used to treat tuberculosis. The drug is largely bacteriostatic, but can be bacteriocidal on actively replicating tuberculosis bacteria.

It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system. Pyrazinamide is a pyrazine that is used therapeutically as an antitubercular agent.Target: AntibacterialPyrazinamide is a prodrug that stops the growth of Mycobacterium tuberculosis. Pyrazinoic acid was thought to inhibit the enzyme fatty acid synthase (FAS) I, which is required by the bacterium to synthesise fatty acids although this has been discounted. It was also suggested that the accumulation of pyrazinoic acid disrupts membrane potential and interferes with energy production, necessary for survival of M. tuberculosis at an acidic site of infection. Pyrazinoic acid binds to the ribosomal protein S1 (RpsA) and inhibits trans-translation. This may explain the ability of the drug to kill dormant mycobacteria.
