Prothionamide

Introduction

Prothionamide is an antibiotic medicine used to treat tuberculosis, especially multidrug-resistant tuberculosis (MDR-TB). It belongs to the group of medicines known as thioamides and works effectively against Mycobacterium tuberculosis. It is often used in combination with other anti-tuberculosis drugs to enhance effectiveness and prevent resistance. Prothionamide is usually prescribed when first-line TB medications are not sufficient. It should be taken only under strict medical supervision due to its strong effects and potential side effects.
