Pharmacological properties
Sulfadimezin is a short-acting sulfanilamide drug. Active against gram-positive and gram-negative cocci, Escherichia coli, Shigella, Klebsiella, Vibrio cholerae, pathogens of gas gangrene, anthrax, diphtheria, catarrhal pneumonia, plague, as well as chlamydia, actinomycetes, toxoplasmosis pathogens. Acts bacteriostatically. The mechanism of action is associated with para-aminobenzoic acid (PABA) and competitive inhibition of dihydropteroate synthetase, which leads to disruption of the synthesis of tetrahydrofolic acid, which is necessary for the synthesis of purines and pyrimidines.

Overdose
Symptoms: anorexia, abdominal cramping, nausea, vomiting, dizziness, headache, drowsiness, loss of consciousness. Hyperthermia, hematuria, crystalluria are possible. Pathological changes in the blood (leukopenia, agranulocytosis, hemolytic anemia) and jaundice are later manifestations of overdose. Development of methemoglobinemia is possible.
Treatment: immediate discontinuation of the drug, gastric lavage, an enhanced drinking regimen of solutions that alkalize urine is shown; with a decrease in urine output and normal renal function – intravenous administration of solutions. Further – symptomatic treatment.
When methemoglobinemia is confirmed, intravenous administration of 1% methylene blue is indicated.
Peritoneal dialysis is not effective, hemodialysis is only moderately effective in treating sulfonamide overdose.

  • The same side reactions are possible as with the use of other sulfonamides.
  • Digestive system: pain in the abdomen, dyspeptic symptoms, including nausea, vomiting, diarrhea, anorexia; stomatitis, sialoadenitis, pancreatitis, pseudomembranous colitis.
  • Hepatobiliary system: increased serum levels of hepatic transaminases, hepatomegaly, occasionally jaundice, hepatitis, possible hepatonecrosis.
