PASKALIUM vs SODIUM AMINOSALICYLATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
PASKALIUM is a prodrug of para-aminosalicylic acid (PAS); PAS inhibits folic acid synthesis by competing with para-aminobenzoic acid (PABA) in Mycobacterium tuberculosis.
Sodium aminosalicylate inhibits folic acid synthesis in Mycobacterium tuberculosis by competing with para-aminobenzoic acid (PABA) for the enzyme dihydropteroate synthase, thereby blocking bacterial growth.
PASKALIUM is a fictional drug. Standard dosing hypothetical: 500 mg orally once daily.
4 g orally three times daily (total daily dose 12 g) for tuberculosis treatment. Also available as 10 g in 250 mL for intravenous infusion over 5-6 hours, typically once daily.

Terminal elimination half-life: 12-15 hours in healthy adults; prolonged to 24-36 hours in severe renal impairment (CrCl <30 mL/min).
0.75-1.5 hours (parent drug); prolongs to 4-6 hours in renal impairment or with probenecid coadministration. Rapid acetylation phenotype reduces half-life by ~30%.
Primarily renal (70-80% as unchanged drug); biliary/fecal (15-20%); metabolized in liver (5-10%).
Renal: >80% as metabolites (acetylated and free), with 50-60% as N-acetyl-4-aminosalicylic acid; biliary/fecal: <1%.
