History of aspirin Peto convinced the U.S. FDA and much of the medical community that the aspirin studies, in aggregate, showed aspirin's effectiveness with relative certainty. By the end of the 1980s, aspirin was widely used as a preventive drug for heart attacks and had regained its former position as the top-selling analgesic in the U.S. History of aspirin The history of aspirin (IUPAC name acetylsalicylic acid ) begins with its synthesis and manufacture in 1899. Before that, salicylic acid had been used medicinally since antiquity. Medicines made from willow and other salicylate-rich plants appear in clay tablets from ancient Sumer as well
Pamoic acid Pamoic acid Pamoic acid, also called embonic acid, is a naphthoic acid derivative. Salts and esters of pamoic acid are known as pamoates or embonates. It can be prepared by the reaction of 2-hydroxy-3-naphthoic acid with formaldehyde. In pharmacology, the salt form of pamoic acid (pamoate ion) can be used as a counterion of a drug compound to affect the dissolution rate of the drug. The presence of multiple oxygen atoms enables significant hydrogen bonding to occur. Hydrogen bonds facilitate the dissolution of compounds in water. Pharmaceutical drugs formulated this way include cycloguanil pamoate, hydroxyzine pamoate, imipramine pamoate, olanzapine pamoate
