The result was a sulfa craze. [11] For several years in the late 1930s, hundreds of manufacturers produced myriad forms of sulfa. This and the lack of testing requirements led to the elixir sulfanilamide disaster in the fall of 1937, during which at least 100 people were poisoned with diethylene glycol.
Around 90% of a dose of sulfasalazine reaches the colon, where most of it is metabolized by bacteria into sulfapyridine and mesalazine (also known as 5-aminosalicylic acid or 5-ASA). Both metabolites are active; most of the sulfapyridine is absorbed and then further metabolized, but most mesalazine is not, and remains in the colon.
Sulfapyridine is no longer prescribed for treatment of infections in humans. However, it may be used to treat linear IgA disease and has use in veterinary medicine . [ 1 ] It is a good antibacterial drug, but its water solubility is very pH dependent.
Sulfanilamide is a yellowish-white or white crystal or fine powder. It has a density of 1.08 g/cm 3 and a melting point of 164.5-166.5 °C. The pH of a 0.5% aqueous solution of Sulfanilamide is 5.8 to 6.1. It has a λ max of 255 and 312 nm. [5] Solubility: One gram of sulphanilamide dissolves in approximately 37 ml alcohol or in 5 ml acetone.
The claims for the need for sulfur supplementation originate with Robert Herschler, a biochemist who filed a patent for using MSM as a dietary supplement in 1982. [ 25 ] Moreover, in cases involving topical therapeutics, the role of MSM as an active agent, per se, versus its having a role in promoting skin permeation (in manner, akin to its ...
Sulfadiazine is available in multiple generic tablets of 500 mg. For urinary tract infections, the usual dose is 4 to 6 grams daily in 3 to 6 divided doses. [4] Common side effects include nausea, diarrhea, headache, fever, rash, depression, and pancreatitis. [1]

It comes in yellow flakes and has been used in traditional and alternative medicine for humans and animals, as well as in alchemy and sulfuring fruit before drying. Purified sulfur (sulfur depuratum) is prepared by washing sublimed sulfur with ammonia. It is a fine yellow powder. It was formerly used as a laxative, but this application is rare ...
