What is the classification of Rifampicin?

Rifampicin is classified as an antibiotic, specifically a bactericidal antibiotic. It is primarily used in the treatment of bacterial infections, particularly tuberculosis and leprosy. The mechanism of action of Rifampicin involves inhibiting bacterial RNA polymerase, which is crucial for bacterial transcription. By binding to the RNA polymerase, Rifampicin effectively stops the synthesis of RNA, leading to the death of the bacteria.

This classification distinguishes it from other types of agents such as viral agents, which target viruses, antifungals that combat fungal infections, and antiparasitics that are used against parasites. Each of these categories has distinct mechanisms and target organisms, but Rifampicin's role in disrupting bacterial function underlines its specific classification as an antibiotic.
