Rifampin-Isoniazid-Ethambutol-Pyrazinamide 150mg-75mg-275mg-400mg

Rifampin-Isoniazid-Ethambutol-Pyrazinamide Uses

This combination medication is prescribed for:

• Active Tuberculosis (TB): Treats both pulmonary and extrapulmonary TB in its active phase.
• Combination Therapy: Used as part of a multi-drug regimen to ensure effective bacterial eradication and prevent resistance.
• Initial Phase Treatment: Administered during the intensive phase of TB treatment to rapidly reduce bacterial load.

This FDC simplifies treatment regimens, ensuring patient compliance and effective TB management.

How Does Rifampin-Isoniazid-Ethambutol-Pyrazinamide Work?

Each component of the combination has a specific role in fighting TB:

• Rifampin: Inhibits bacterial RNA synthesis, preventing bacterial reproduction and growth.
• Isoniazid: Kills actively growing bacteria by inhibiting mycolic acid synthesis, which is essential for bacterial cell walls.
• Ethambutol: Slows bacterial growth by disrupting cell wall formation.
• Pyrazinamide: Targets dormant TB bacteria in acidic environments, helping to shorten treatment duration.

Together, these medications provide a comprehensive approach to eliminating TB bacteria and preventing drug resistance.
