Pharmacology

Indication

A sulfanilamide that is used as an antibacterial agent. It can be used to treat bronchitis, prostatitis and urinary tract infections.

Structured Indications
Not Available
Pharmacodynamics

Sulfonamides act as competitive inhibitors of the enzyme dihydropteroate synthetase (DHPS), an enzyme involved in folate synthesis in bacteria.

Mechanism of action

Sulfamerazine is a sulfonamide drug that inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for binding to dihydropteroate synthetase (dihydrofolate synthetase). Sulfamerazine is bacteriostatic in nature. Inhibition of dihydrofolic acid synthesis decreases the synthesis of bacterial nucleotides and DNA.

TargetActionsOrganism
ADihydropteroate synthase
inhibitor
Escherichia coli (strain K12)

Toxicity

Sulfamerazine may cause nausea, vomiting, diarrhea and hypersensitivity reactions. Hematologic effects such as anemia, agranulocytosis, thrombocytopenia and hemolytic anemia in patients with glucose-6-phosphate dehydrogenase deficiency may also occur. Sulfamethoxazole may displace bilirubin from albumin binding sites causing jaundice or kernicterus in newborns.
