Sulfadiazine Base BP
Sulfadiazine Base BP is a broad-spectrum sulfonamide antibiotic used primarily in veterinary and human medicine to treat bacterial infections. It functions by inhibiting bacterial synthesis of folic acid, thereby preventing bacterial growth and proliferation. The British Pharmacopoeia (BP) grade ensures pharmaceutical-grade purity and quality suitable for formulation into tablets, suspensions, and topical preparations.
Primary Uses
Human Medicine
Antibacterial Agent: Used to treat urinary tract infections, respiratory tract infections, and meningitis caused by susceptible bacteria.
Topical Antimicrobial: Formulated in creams and ointments for treating burns and wound infections.
Veterinary Medicine
Animal Antibiotic: Used to treat infections in livestock and pets, including respiratory, urinary, and soft tissue infections.
Feed Additive: Sometimes included in medicated feed for prophylactic or therapeutic purposes.
Secondary Uses
Research & Development
Microbiological Studies: Used in lab research to study bacterial resistance and antibiotic mechanisms.
Pharmaceutical Formulation: Employed as a model drug in formulation development and bioavailability studies.
Aquaculture
Fish Medication: Used to control bacterial diseases in aquaculture under veterinary supervision.
