How does the drug work ?
Rifampicin is known as a broad-spectrum antibiotic which means it kills a wide range of infection causing bacteria. It blocks the activity of DNA-dependent RNA polymerase (bacterial enzyme) essential for important life processes in the bacteria, thereby, killing them. Isoniazid belongs to a class of drugs known as antituberculosis drugs. It acts by inhibiting the synthesis of mycolic acid (an essential component of the bacterial cell wall) thereby suppressing their growth.
