Synthesis and pharmacological properties of eterylate, a new derivative of acetylsalicylic acid.

A description is given of the synthesis and main physical and chemical properties of a new derivative of acetylsalicylic acid which we have called eterylate and which is 2-(p-acetamidophenyloxy)-ethyl-o-acetoxy-benzoate. The anti-inflammatory and analgesic action of the preparation was studied and found to be comparable to that of acetylsalicylic acid and benorylate. Nevertheless, eterylate is tolerated better than the latter product, as is shown by toxicity tests and studies of the digestive system.
