Sulfonamide functional group Hydrochlorothiazide is a sulfonamide and a thiazide. Furosemide is a sulfonamide, but not a thiazide. Sulfamethoxazole is an antibacterial sulfonamide. Sulfonamide is a functional group (a part of a molecule) that is the basis of several groups of drugs, which are called sulphonamides, sulfa drugs or sulpha drugs.
The structure of the sulfonamide group. In organic chemistry, the sulfonamide functional group (also spelled sulphonamide) is an organosulfur group with the structure R−S(=O) 2 −NR 2. It consists of a sulfonyl group (O=S=O) connected to an amine group (−NH 2). Relatively speaking this group is unreactive.
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 ...
Allergic reactions to Sulfonamides have been shown to include the entire Gel-Coombs spectrum of hyperactivity reactions. [9] Type 1 reactions include immunoglobulin E (IgE)-mediated reactions such as urticaria, angioedema, and anaphylaxis. In contrast, non-type 1 hypersensitivities are believed to be caused by metabolites of sulfonamides. [10]

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.
Sulfacetamide is a sulfonamide antibiotic. [1] Sulfonamides are synthetic bacteriostatic antibiotics, that are active against gram-positive and gram-negative bacteria. It blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. It is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA).
