Para Aminosalicylic Acid

Para aminosalicylic acid (PAS) is an antibiotic used primarily in the treatment of tuberculosis (TB), particularly when other first-line treatments are not effective. It works as a second-line agent in multidrug-resistant tuberculosis (MDR-TB) cases. PAS belongs to the class of drugs known as anti-tuberculars and inhibits the growth of Mycobacterium tuberculosis, the bacteria responsible for TB. It is often used in combination with other anti-TB medications to improve effectiveness and prevent resistance.
