I recently read about a compound called copper aspirinate: https://en.wikipedia.org/wiki/Copper_aspirinate which is used to treat rheumatoid arthiris. Since the copper atom coordinates aspirin molecules, it also according to wikipedia: which I assume means it has the anticoagulant properties of aspirin. I also read that this complex does not have the toxic effects associated with ingesting copper or aspirin by themselves. My granny has severe arthritis and she is also on high doses of aspirin for its anticoagulant properties (which makes no sense to me since baby aspirin is all you need to protect the heart). Have any of you any experience with this drug? I'm thinking of getting my granny to mention it to her doctor because the difene shes on (an antiinflammatory for arthritis) combined with the high doses of aspirin is causing her stomach problems.
