Zinamide is a pharmaceutical drug primarily used in the treatment of tuberculosis (TB), an infectious disease caused mainly by the bacterium Mycobacterium tuberculosis. It is known generically as Pyrazinamide, an important component in the standard short-course chemotherapy for TB. Zinamide works by stopping the growth of TB bacteria, which helps the body's immune system to fight the infection more effectively. It is typically used in combination with other TB medications to prevent the development of drug resistance. The drug is taken orally, and while it is effective in treating tuberculosis, it can also cause side effects such as liver damage, joint pain, and nausea in some patients. Regular monitoring by a healthcare provider is recommended to manage these potential side effects and to ensure the effectiveness of the treatment regimen.
