Antibacterial Agent: Occasionally used to treat bacterial infections susceptible to sulfonamides, particularly in tropical regions.
Veterinary Medicine
Antimicrobial Agent: Used in combination therapies for prevention and treatment of protozoal and bacterial infections in livestock.
Secondary Uses
Research & Development
Pharmaceutical Studies: Used in pharmacokinetic and formulation research for antimalarial and sulfonamide drugs.
Drug Resistance Monitoring: Utilized in studies monitoring drug resistance patterns in malaria parasites.
Public Health Programs
Mass Drug Administration: Employed in malaria-endemic regions as part of public health interventions.
