Description

Pyrazinamide was synthesized in 1952, and it is the nitrogen-analog of nicotinamide. It exhibits hepatotoxicity. Synonyms of this drug are dexambutol, miambutol, esnbutol, ebutol, and others.

The Uses of Pyrazinamide

Pyrazinamide is used therapeutically as an antitubercular agent. Pyrazinamide is used to form polymeric copper complexes, create pyrazine carboxamide scaffolds useful as FXs inhibitors, and as a component of mycobacteria identification kits. It is used to study liver toxicity prevention and mechanisms of resistance .

Background

A pyrazine that is used therapeutically as an antitubercular agent.

Indications

For the initial treatment of active tuberculosis in adults and children when combined with other antituberculous agents.

What are the applications of Application

Pyrazinamide is an antibacterial agent used to study liver toxicity prevention

Pharmacokinetics

Pyrazinamide kills or stops the growth of certain bacteria that cause tuberculosis (TB). It is used with other drugs to treat tuberculosis. It is a highly specific agent and is active only against Mycobacterium tuberculosis. In vitro and in vivo, the drug is active only at a slightly acid pH. Pyrazinamie gets activated to Pyrazinoic acid in the bacilli where it interferes with fatty acid synthase FAS I. This interferes with the bacteriums ability to synthesize new fatty acids, required for growth and replication.

Metabolism

Hepatic.
