Copper aspirinate use of copper aspirinate as a pigment in PVC and Polystyrene has also been investigated. Copper aspirinate Copper(II) aspirinate is an aspirin chelate of copper(II) cations (Cu). It is used to treat rheumatoid arthritis. Copper aspirinate can be prepared by several methods. In one route of preparation, an excess of acetylsalicylic acid is dissolved in aqueous sodium carbonate. Sodium hydroxide is not suitable for this purpose, because it will hydrolyse acetylsalicylic acid ("ASA") into salicylic acid and sodium acetate. The resulting solution is then filtered to remove any undissolved acetylsalicylic acid and is mixed with a solution containing Cu cations
Bernardino Ramazzini medicine and played a substantial role in its development. He proposed that physicians should extend the list of questions that Hippocrates recommended they ask their patients by adding, "What is your occupation?". Ramazzini saw prevention as being better than cure. In his Oratio given in 1711, he suggested that "it is much better to prevent than to cure, and so much easier to foresee future harm and avoid it rather than have to get rid of it after having fallen prey". In regards to malaria, Ramazzini was one of the first to support the use of the quinine-rich bark cinchona.
