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.
One study has suggested women are more likely to be resistant than men, [157] and a different, aggregate study of 2,930 people found 28% were resistant. [158] A study in 100 Italian people found, of the apparent 31% aspirin-resistant subjects, only 5% were truly resistant, and the others were noncompliant. [159] Another study of 400 healthy ...
Mechanism of action of aspirin. Tridimensional model of the chemical structure of aspirin. 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 ...
A new DNA test suggests they might have even self-prescribed an early version of a common modern day painkiller.
Raffaele Piria (Scilla 20 August 1814 – Turin 18 July 1865) was an Italian chemist from Scilla, who lived in Palmi. He converted the substance Salicin into a sugar and a second component, which on oxidation becomes salicylic acid, a major component of the analgesic drug Aspirin (acetylsalicylic acid). [1] Other reactions discovered by Piria ...
Figure 1: The chemical structure of dichloroisoprenaline or dichloroisoproterenol (), abbreviated DCI — the first β-blocker to be developed. β adrenergic receptor antagonists (also called beta-blockers or β-blockers) were initially developed in the 1960s, for the treatment of angina pectoris but are now also used for hypertension, congestive heart failure and certain arrhythmias.

Pain ladder. "Pain ladder", or analgesic ladder, was created by the World Health Organization (WHO) as a guideline for the use of drugs in the management of pain. Originally published in 1986 for the management of cancer pain, it is now widely used by medical professionals for the management of all types of pain.
1824 – Henri Dutrochet discovers that tissues are composed of living cells. 1838 – Protein discovered, named and recorded by Gerardus Johannes Mulder and Jöns Jacob Berzelius. 1862 – Louis Pasteur discovers the bacterial origin of fermentation. 1863 – Gregor Mendel discovers the laws of inheritance.
