Applications · 4 items

DescriptionSulfamethazine is an antibacterial sulfonamide. Like other sulfonamides, sulfamethazine is bacteriostatic, competitively inhibiting dihydropteroate synthase to block folate synthesis and inhibit growth and multiplication. Sulfamethazine is metabolized by cytochrome P450 isoforms and arylamine N-acetyltransferase 2 in a sex-dependent manner.

UsesSulfamethazine is an antibacterial.This compound is a contaminant of emerging concern (CECs).

General DescriptionSulfamethazine’splasma half-life is 7 hours. This compound is similar inchemical properties to sulfamerazine and sulfadiazine butdoes have greater water solubility than either. Its pKa is 7.2.Because it is more soluble in acid urine than sulfamerazineis, the possibility of kidney damage from use of the drug isdecreased. The human body appears to handle the drugunpredictably; hence, there is some disfavor to its use in thiscountry except in combination sulfa therapy (in trisulfapyrimidines,USP) and in veterinary medicine.

General DescriptionOdorless sticky, white or creamy-white crystalline powder. Slightly bitter taste. An antibacterial.
