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 original antibacterial sulfonamides are synthetic (nonantibiotic) antimicrobial agents that contain the sulfonamide group. Some sulfonamides are also devoid of antibacterial ...
A sulfonamide (compound) is a chemical compound that contains this group. The general formula is R−SO2NR'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 CH3SO2NH2. Any sulfonamide can be considered as derived from a sulfonic acid by replacing a ...
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.

Sulfonamides (such as sulfanilamide, sulfamethoxazole, and mafenide), thiazolesulfone, methylene blue, and naphthalene should also be avoided by people with G6PD deficiency as they antagonize folate synthesis, as should certain analgesics (such as phenazopyridine and acetanilide) and a few non-sulfa antibiotics (nalidixic acid, nitrofurantoin ...
Torasemide. Highly bound (>99%). Torasemide, also known as torsemide, is a diuretic medication used to treat fluid overload due to heart failure, kidney disease, and liver disease. It is a less preferred treatment for high blood pressure. [1] It is taken by mouth or by injection into a vein.
“Nausea is a symptom that can occur due to many underlying root causes, but if it specifically occurs after eating, it likely is due to abnormalities in the gastrointestinal system,” explains ...
When higher doses are used, as in the treatment of toxoplasmosis, pyrimethamine can cause gastrointestinal symptoms such as nausea, vomiting, glossitis, anorexia, and diarrhea. [11] [13] A rash, which can be indicative of a hypersensitivity reaction, is also seen, particularly in combination with sulfonamides. [11]
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 ...
