Full Form of PZA
What is PZA?
Pyrazinamide, abbreviated as PZA, is a first-line antibiotic widely used in the treatment of tuberculosis (TB). It is part of the standard four-drug regimen (Rifampicin, Isoniazid, Pyrazinamide, Ethambutol) recommended globally and by India’s Revised National Tuberculosis Control Program (RNTCP). PZA is particularly effective against intracellular Mycobacterium tuberculosis organisms, especially in the acidic environment of the caseous lesions. Its inclusion in the intensive phase (first two months) of therapy shortens treatment duration and reduces relapse rates. In India, where TB remains a major public health challenge with high burden, PZA is a cornerstone of the DOTS strategy. The drug is usually administered orally and is well-absorbed. Common side effects include hepatotoxicity and hyperuricemia, so liver function monitoring is essential. PZA is also used off-label for some non-tuberculous mycobacterial infections. For medical students and healthcare professionals preparing for exams like NEET PG, AIIMS, and public health certifications, understanding the role, mechanism, and adverse effects of PZA is critical. The drug’s bactericidal activity is unique among first-line TB agents, making it indispensable in modern TB management.
