NCIt definition : The sodium salt form of aminosalicylic acid, an analog of para-aminobenzoic acid (PABA)
with antitubercular activity. Aminosalicylate sodium exerts its bacteriostatic activity
against Mycobacterium tuberculosis by competing with PABA for enzymes involved in
folate synthesis, thereby suppressing growth and reproduction of M. tuberculosis,
eventually leading to cell death.;
