Curator's Comment: Description was created based on several sources, including https://www.drugs.com/dosage/sulfadiazine.html

Sulfadiazine is a sulfonamide antibiotic. The sulfonamides are synthetic bacteriostatic antibiotics with a wide spectrum against most gram-positive and many gram-negative organisms. However, many strains of an individual species may be resistant. Sulfonamides inhibit multiplication of bacteria by acting as competitive inhibitors of p-aminobenzoic acid in the folic acid metabolism cycle. Bacterial sensitivity is the same for the various sulfonamides, and resistance to one sulfonamide indicates resistance to all. Most sulfonamides are readily absorbed orally. However, parenteral administration is difficult, since the soluble sulfonamide salts are highly alkaline and irritating to the tissues. The sulfonamides are widely distributed throughout all tissues. High levels are achieved in pleural, peritoneal, synovial, and ocular fluids. Although these drugs are no longer used to treat meningitis, CSF levels are high in meningeal infections. Their antibacterial action is inhibited by pus. Sulfadiazine is a competitive inhibitor of the bacterial enzyme dihydropteroate synthetase. This enzyme is needed for the proper processing of para-aminobenzoic acid (PABA) which is essential for folic acid synthesis. The inhibited reaction is necessary in these organisms for the synthesis of folic acid. Used for the treatment of rheumatic fever and meningococcal meningitis.

Toxoplasmosis encephalitis 3 Sources: https://www.drugs.com/pro/sulfadiazine.html	Curative	Approved 8360	Sulfadiazine Approved Use Sulfadiazine tablets USP are indicated in the following conditions: Chancroid Trachoma Inclusion conjunctivitis Nocardiosis Urinary tract infections (primarily pyelonephritis, pyelitis and cystitis) in the absence of obstructive uropathy or foreign bodies, when these infections are caused by susceptible strains of the following organisms: Escherichia coli, Klebsiella species, Enterobacter species, Staphylococcus aureus, Proteus mirabilis and P. vulgaris. Sulfadiazine should be used for urinary tract infections only after use of more soluble sulfonamides has been unsuccessful. Toxoplasmosis encephalitis in patients with and without acquired immunodeficiency syndrome, as adjunctive therapy with pyrimethamine. Malaria due to chloroquine-resistant strains of Plasmodium falciparum, when used as adjunctive therapy. Prophylaxis of meningococcal meningitis when sulfonamide-sensitive group A strains are known to prevail in family groups or larger closed populations (the prophylactic usefulness of sulfonamides when group B or C infections are prevalent is not proved and may be harmful in closed population groups). Meningococcal meningitis, when the organism has been demonstrated to be susceptible. Acute otitis media due to Haemophilusinfluenzae, when used concomitantly with adequate doses of penicillin. Prophylaxis against recurrences of rheumatic fever, as an alternative to penicillin. H. influenzae meningitis, as adjunctive therapy with parental streptomycin. Launch Date 7.753536E11
