Used primarily as an antimicrobial agent in the treatment of tuberculosis, especially in cases where patients are intolerant to standard first-line drugs. It functions by inhibiting the synthesis of folic acid in mycobacteria, thereby suppressing bacterial growth. Commonly administered in combination with other antituberculosis agents to prevent the development of drug resistance. Also exhibits anti-inflammatory properties, which may contribute to its effectiveness in reducing tissue damage during infection. Typically taken orally and often used in multidrug regimens for pulmonary and extrapulmonary tuberculosis.
