Sulfadoxine mixture with trimethoprim

Sulfadoxine mixture with trimethoprim (CAS 39295-60-8), also known as Tridoxine, is a fixed-ratio antibiotic combination pairing a long-acting sulfonamide with a dihydrofolate reductase inhibitor.

The combination is used across pharmaceutical manufacturing and veterinary sectors for its synergistic antimicrobial action against a broad spectrum of bacterial and protozoal targets.

In human pharmaceutical manufacturing, the combination serves as the active basis for antimalarial finished dosage forms, particularly tablets targeting Plasmodium falciparum in endemic regions.

Veterinary formulators incorporate it into oral and injectable preparations for the treatment of bacterial infections in livestock and poultry. It is a vital component for animal health.

In agricultural and feed applications, it functions as a therapeutic agent in medicated premixes targeting enteric and respiratory pathogens in production animals during large-scale operations.

Biotechnology and life sciences suppliers source it as a reference standard or research-grade material for antimicrobial susceptibility studies and assay development in laboratory settings.

Sulfadoxine mixture with trimethoprim is supplied as a solid powder. It is available in pharmaceutical-grade specifications aligned with established pharmacopoeial standards like USP and BP.

Bulk quantities are typically offered for formulation manufacturers, with smaller reference quantities available for QC and analytical applications to ensure high quality and consistency.
