Sulfadimidine, also known as sulfamethazine, is a sulfonamide antibiotic used in the treatment of various bacterial infections. It is particularly effective against Gram-positive and some Gram-negative bacteria.
Mechanism of Action[edit]
Sulfadimidine works by inhibiting the bacterial synthesis of folic acid, which is essential for bacterial growth and replication. It achieves this by competitively inhibiting the enzyme dihydropteroate synthase, which is involved in the synthesis of dihydrofolic acid. This action ultimately leads to the inhibition of bacterial DNA synthesis.
Pharmacokinetics[edit]
Sulfadimidine is well absorbed from the gastrointestinal tract when administered orally. It is distributed throughout the body, including the central nervous system. The drug is metabolized in the liver and excreted primarily through the kidneys.
Clinical Uses[edit]
Sulfadimidine is used to treat a variety of infections, including:
