Rifampicin is a broad-spectrum antibiotic used primarily for the treatment of tuberculosis and leprosy. It works by inhibiting bacterial DNA-dependent RNA polymerase and is a key component of first-line anti-tuberculosis therapy. Rifampicin is currently approved and widely used in clinical practice.
Pharmacokinetics
Pharmacokinetic parameters reported in adult healthy volunteers following single oral administration of rifampicin.
