ATC code J01EB20 refers to combinations of short-acting sulfonamides, which are antibacterial agents primarily used in the past to treat urinary tract infections and other susceptible bacterial infections. Most sulfonamide combinations are not used widely today due to resistance and the development of newer antibiotics.
Pharmacokinetics
Estimated pharmacokinetic parameters for adult patients receiving oral sulfonamide combinations (e.g., sulfadiazine + sulfamerazine), as scientific publications with explicit population PK models for these combinations are lacking.
