CAPREOMYCIN SULFATE vs SODIUM AMINOSALICYLATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, causing misreading of mRNA and inhibiting translation initiation. Also alters membrane permeability.
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.
15 mg/kg (up to 1 g) intramuscularly or intravenously once daily for 60 days, then 15 mg/kg (up to 1 g) 2-3 times weekly for 12-18 months in combination with other antituberculosis agents.
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: 24-40 hours (prolonged in renal impairment; anuria may extend to 96-120 hours).
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 (80-90% as unchanged drug via glomerular filtration). Biliary/fecal elimination: <1%.
Renal: >80% as metabolites (acetylated and free), with 50-60% as N-acetyl-4-aminosalicylic acid; biliary/fecal: <1%.
