ECHEMI Editorial Reference

4-Aminosalicylic acid (ASA) is an orally active antibiotic and has the potential to treat tuberculosis[1].
Solid
4-aminosalicylic acid is an aminobenzoic acid that is salicylic acid substituted by an amino group at position 4. It has a role as an antitubercular agent. It is an aminobenzoic acid and a member of phenols. It derives from a salicylic acid. It is a conjugate acid of a 4-aminosalicylate(1-).|An antitubercular agent often administered in association with isoniazid. The sodium salt of the drug is better tolerated than the free acid.|Aminosalicylic Acid is an analog of para-aminobenzoic acid (PABA) with antitubercular activity. Aminosalicylic acid 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.|An antitubercular agent often administered in association with ISONIAZID. The sodium salt of the drug is better tolerated than the free acid.
