History of aspirin. Aspirin (acetylsalicylic acid), an organic compound that does not occur in nature, was first synthesised in 1899. In 1897, scientists at the drug and dye firm Bayer began investigating acetylated organic compounds as possible new medicines, following the success of acetanilide ten years earlier.
[13]: 69–75 [18] By 1899, Bayer had named it "Aspirin" and was selling it around the world. [19] Aspirin's popularity grew over the first half of the 20th century, leading to competition between many brands and formulations. [20] The word Aspirin was Bayer's brand name; however, its rights to the trademark were lost or sold in many countries ...
[8] [14] Ibuprofen was first marketed in 1969 in the United Kingdom and in 1974 in the United States. [8] [13] It is on the World Health Organization's List of Essential Medicines. [15] It is available as a generic medication. [8] In 2022, it was the 33rd most commonly prescribed medication in the United States, with more than 17 million ...
A new DNA test suggests they might have even self-prescribed an early version of a common modern day painkiller.
The history of syphilis has been well studied, but the exact origin of the disease remains unknown. [3] It appears to have originated in both Africa and America. [4] [5] As such, there are two primary hypotheses: one proposes that syphilis was carried to Europe from the Americas by the crew(s) of Christopher Columbus as a byproduct of the Columbian exchange, while the other proposes that ...
The discoveries of the 118 chemical elements known to exist as of 2024 are presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined. There are plans to synthesize more elements, and it ...
Medicinal plants. The bark of willow trees contains salicylic acid, the active metabolite of aspirin, and has been used for millennia to relieve pain and reduce fever. [1] Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical ...
A derivative of timoprazole, omeprazole, was discovered in 1979, and was the first of a new class of drug that control acid secretion in the stomach, a proton pump inhibitor (PPI). [ 11 ] [ 12 ] Addition of 5-methoxy-substitution to the benzimidazole moiety of omeprazole was also made and gave the compound much more stability at neutral pH. [ 6 ]
