It has therefore been argued that the terms "sulfonamide allergy" or "sulfa allergy" are misleading and should be replaced by a reference to a specific drug (e.g., "cotrimoxazole allergy"). [20] Two regions of the sulfonamide antibiotic chemical structure are implicated in the hypersensitivity reactions associated with the class.
Many important drugs contain the sulfonamide group. [1] A sulfonamide (compound) is a chemical compound that contains this group. The general formula is R−SO 2 NR'R" or R−S(=O) 2 −NR'R", where each R is some organic group; for example, "methanesulfonamide" (where R = methane, R' = R" = hydrogen) is CH 3 SO 2 NH 2.
It is in the sulfonamide class of medications. [1] Sulfadiazine was approved for medical use in the United States in 1941. [1] [5] It is on the World Health Organization's List of Essential Medicines. [6] Sulfadiazine is available as a generic medication. [1]
Antibacterials like dapsone (increases plasma levels of both drugs), methenamine (increased risk of crystalluria) and rifampicin (as it may lead to an increased plasma level of rifampicin and lower plasma levels of trimethoprim) Anticoagulants like warfarin and acenocoumarol — anticoagulant effects of either drug is potentiated by this ...
Its Tmax (or time to reach maximum drug concentration in plasma) occurs 1 to 4 hours after oral administration. The mean serum half-life of sulfamethoxazole is 10 hours. [8] However, the half-life of the drug noticeably increases in people with creatinine clearance rates equal to or less than 30 mL/minute.
Prontosil is an antibacterial drug of the sulfonamide group. It has a relatively broad effect against gram-positive cocci but not against enterobacteria.One of the earliest antimicrobial drugs, it was widely used in the mid-20th century but is little used today because better options now exist.
Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial drug. Chemically, it is an organic compound consisting of an aniline derivatized with a sulfonamide group. [ 1 ] Powdered sulfanilamide was used by the Allies in World War II to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to ...
