Aspirin, one of the first drugs to come into common usage, is still widely used around the world with approximately 40,000 tonnes produced globally each year 1.

Through acetylation, Aspirin irreversibly inactivates both COX-1 and COX-2. The brand name came from 'a' for acetyl, 'spir' for the spirea plant (another source of salicin besides willow), and the suffix 'in', which is used in chemistry to name compounds. This circumstance made it impossible to write a high profile rebuttal, although he did write a letter in 1944 during a period in the Theresienstadt concentration camp, in which he described how his name was not positioned alongside his invention of acetylcellulose in the German Museum in Munich, whereas both Dreser and Hoffmann were credited beside the exhibition for aspirin.

Those who doubt Sneader's paper have noted that Eichengrün waited 15 years to refute the claims about Hoffman and his father published in 1934. Reports from these effects were encouraging, according to Sneader, with the drug able to provide antirheumatic effects without side effects, such as tinnitus.

Bayer patented this re-synthesizing process process. Gerhardt's product worked but he had no desire to market it and abandoned his discovery.

Aspirin causes several different effects in the body, mainly the reduction of inflammation, analgesia (relief of pain), the prevention of clotting, and the reduction of fever.Much of this is believed to be due to decreased production of prostaglandins and TXA2.Aspirin's ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX) … That year, the first Aspirin tablets were made. It wasn't until the middle of the 18th century that an English Reverend by the name of Edward Stone performed what can be considered a clinical trial of the willow bark.

It works by suppressing the production of thromboxanes and prostaglandin through inactivation of COX enzymes. Instead, Sneader explains that Hoffman's research into synthesising acetylsalicylic acid was actually done under the instruction of his colleague Arthur Eichengrün. As a result, Hoffman is often credited for inventing aspirin, and was named as the inventor on the US patent, although is unclear if he made the discovery himself or if it was made based on Arthur Eichengrun's instruction.

In 1828, a professor of pharmacology at Germany's Munich University by the name of Johann Buchner managed to extract, refine, and thus isolate the willow plant's active ingredient.

It is a mild, non-narcotic analgesic that’s useful in the relief of headache as well as muscle and joint aches.

Mostly by chanceAccording to Bayer's biography of Hoffman, it was 'mostly by chance' that the chemist succeeded in mixing salicylic acid with acetic acid to create what is now widely recognised as a breakthrough treatment in the history of medicine. Before 1915, Aspirin was first sold as a powder. To learn more, visit our Earning Credit Page. By doing so, he was able to show that something in the willow tree could help treat these symptoms. This circumstance made it impossible to write a high profile rebuttal, although he did write a letter in 1944 during a period in the Theresienstadt concentration camp, in which he described how his name was not positioned alongside his invention of acetylcellulose in the German Museum in Munich, whereas both Dreser and Hoffmann were credited beside the exhibition for aspirin. Aspirin is one of the most commonly researched drugs in the world today, with over 700 clinical trials conducted each year. A common story to explain Hoffman's research is that he was encouraged by his father, who had arthritis, to develop an alternative treatment to sodium salicylate – juice from the willow tree bark that had been used for centuries as a painkiller and treatment for fever, but carried several unpleasant side effects, including nausea, gastro-intestinal irritation, tinnitus and liver damage. Bayer patented this re-synthesizing process process.
