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.
Aspirin, also known as acetylsalicylic acid (ASA), is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce pain, fever, and/or inflammation, and as an antithrombotic. [10] Specific inflammatory conditions that aspirin is used to treat include Kawasaki disease, pericarditis, and rheumatic fever.
Felix Hoffmann (21 January 1868 – 8 February 1946) was a German chemist notable for re-synthesising diamorphine (independently from C.R. Alder Wright who synthesized it 23 years earlier), which was popularized under the Bayer trade name of "heroin". He is also credited with synthesizing aspirin, though whether he did this under his own ...
Additionally, aspirin induces the formation of NO-radicals in the body, which have been shown in mice to have an independent mechanism of reducing inflammation. This reduces leukocyte adhesion, which is an important step in immune response to infection. There is currently insufficient evidence to show that aspirin helps to fight infection. [17]
In 1832 produced chloral hydrate, the first synthetic sleeping drug. In 1833 French chemist Anselme Payen was the first to discover an enzyme, diastase. In 1834, François Mothes and Joseph Dublanc created a method to produce a single-piece gelatin capsule that was sealed with a drop of gelatin solution.
1908 – Victor Horsley and R. Clarke invents the stereotactic method. 1909 – First intrauterine device described by Richard Richter. [102] 1910 – Hans Christian Jacobaeus performs the first laparoscopy on humans. 1917 – Julius Wagner-Jauregg discovers the malarial fever shock therapy for general paresis of the insane.
The Bulfinch Building, home of the Ether Dome. Throughout recorded history, attempts at producing a state of general anesthesia can be traced back to the writings of ancient Sumerians, Babylonians, Assyrians, Egyptians, Indians, and Chinese. Despite significant advances in anatomy and surgical technique during the Renaissance, surgery remained ...
Heinrich Dreser (1 October 1860 – 21 December 1924) was a German chemist responsible for the aspirin and heroin projects at Bayer AG. He was also a key figure in creating the widely used modern drug codeine. Dreser was born in Darmstadt, Grand Duchy of Hesse.
