About Isoniazid+pyrazinamide+pyridoxine+rifampicin
Isoniazid+pyrazinamide+pyridoxine+rifampicin belongs to the group of medicines called 'anti-tuberculosis drugs primarily used to treat and prevent 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. Isoniazid+pyrazinamide+pyridoxine+rifampicin does not work against infections caused by the virus, such as the common cold and flu.
Isoniazid+pyrazinamide+pyridoxine+rifampicin is a combination of four drugs: Isoniazid, Pyrazinamide, Pyridoxine (vitamin B6), and Rifampicin. Isoniazid inhibits the biosynthesis of mycolic acid, which is the major component of the bacterial cell wall. Pyrazinamide is an antibiotic that works by stopping the growth of bacteria that cause tuberculosis. Pyridoxine treats nerve damage (neuritis) caused by tuberculosis. Rifampicin inhibits DNA dependent RNA polymerase activity in the bacteria.

Disease/Condition Glossary
Tuberculosis (TB): Tuberculosis is an infectious disease that affects the lungs, but it could also spread to other body parts such as kidneys, brain, spine, and bone marrow. Tuberculosis is caused by a bacteria named Mycobacterium tuberculosis. It is a contagious disease that can spread to others through small droplets released into the air by a person suffering from tuberculosis. Symptoms include a cough that lasts for a few weeks, pain while coughing or normal breathing, unexplained fatigue, fever, night sweats, loss of appetite and weight. People who smoke or consume alcohol, people diagnosed with HIV, and immune system problems are more likely at risk of developing active TB.
