Pyzina (Pyrazinamide): Anti-TB Tablets | For Tuberculosis Therapy and Mycobacterial Infection Control
Product Overview
Pyzina Suspension is an oral antitubercular formulation containing Pyrazinamide, used as part of combination therapy for the treatment of tuberculosis (TB). It is particularly important during the intensive phase of treatment and is administered in combination with other antitubercular medicines to help eliminate Mycobacterium tuberculosis.
Pyrazinamide is converted within the body to its active form, pyrazinoic acid, which has enhanced activity against susceptible M. tuberculosis, particularly under acidic conditions. Its inclusion in multidrug TB regimens helps shorten the overall duration of therapy when used appropriately.

Mechanism Insights (How It Works)
Conversion to Active Form
Pyrazinamide is converted by mycobacterial enzymes into pyrazinoic acid, its active metabolite.
Action Against Tuberculosis Bacilli
The active metabolite contributes to disruption of important metabolic processes within M. tuberculosis, particularly under acidic conditions associated with infected tissues and intracellular environments.
Reduction of Bacterial Persistence
By affecting the survival of susceptible tubercle bacilli, pyrazinamide helps reduce the bacterial population and contributes to the effectiveness of combination TB therapy.
Administration Guidelines
Shake the suspension well before use.
Administer strictly according to the physician's prescription or tuberculosis treatment regimen.
May be taken with or without food; follow the specific instructions provided by the healthcare professional.
Use the measuring device supplied with the product to ensure accurate dosing.
Complete the full prescribed TB treatment regimen and do not stop therapy prematurely.
Clinical Considerations
Pyrazinamide is generally not used alone for tuberculosis because combination therapy is required to reduce the risk of treatment failure and drug resistance.
It is commonly included during the initial/intensive phase of standard TB treatment.
Dose selection is generally based on factors such as body weight, age, treatment regimen, and clinical circumstances.
Liver function may need monitoring because pyrazinamide can cause hepatotoxicity.
Patients should promptly report symptoms such as persistent nausea, vomiting, loss of appetite, abdominal discomfort, dark urine, or yellowing of the skin/eyes.
The oral suspension can be useful when swallowing tablets is difficult, including in appropriate pediatric treatment settings.
