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 ...
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.
Sulfasalazine, sold under the brand name Azulfidine among others, is a medication used to treat rheumatoid arthritis, ulcerative colitis, and Crohn's disease. [5] It is considered by some to be a first-line treatment in rheumatoid arthritis. [6] It is taken by mouth or can be administered rectally. [5]
It is approved in the United States as a treatment and preventive measure against malaria. [6] The combination is considered to be more effective in treating malaria caused by Plasmodium falciparum than that caused by P. vivax, for which chloroquine is considered more effective, though in the absence of a species-specific diagnosis, the sulfadoxine-pyrimethamine combination may be indicated.

Sulfacetamide is a sulfonamide antibiotic, that is used as a cream to treat skin infections and as eye drops to treat eye infections. On the skin it is used to treat acne and seborrheic dermatitis. [1] In cream form it is used to treat bacterial infections on the skin. It can also be used orally to treat urinary tract infections. [2]
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. A half-life of 22–50 hours has been reported for people with creatinine clearances of less than 10 mL/minute. [11] Metabolism
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.
Dapsone is commonly used in combination with rifampicin and clofazimine for the treatment of leprosy. [4] It is also used to both treat and prevent pneumocystis pneumonia (PCP). [4] [10] It is also used for toxoplasmosis in people unable to tolerate trimethoprim with sulfamethoxazole. [10]
