Key Market Drivers

Rising Global Tuberculosis Incidence

Tuberculosis continues to be one of the world’s leading infectious diseases, with millions of new cases reported annually. The persistent burden of TB, particularly in developing regions, remains the primary driver for the Isoniazid market. The drug’s role as a first-line therapy ensures continuous global demand.
