Use of 2-ethoxy benzoic acid for the manufacture of a medicament as analgesic, antipyretic, and/or antiphlogistic

摘要

The present invention relates to a medicament with an analgesic, antipyretic and/or antiinflammatory effect based on a salicylic acid derivative. The state of the art is always searching for alternatives to active ingredients such as acetylsalicylic acid (ASA) and ethenzamide in order to eliminate intolerance or to be able to offer simpler and better ingredients, which act as rapidly as possible, for a wide variety of possible administrations. Surprisingly, the invention has now succeeded in demonstrating that ethenzamide is very rapidly and completely metabolised in the human body to 2-Ethoxybenzoic acid. Ethenzamide is only a prodrug. It was possible to rule out metabolism to salicylamide. It was likewise possible to demonstrate the analgesic effect of 2-ethoxybenzoic acid. It correlates with the serum levels and persists for more than 8 hours. 2-Ethoxybenzoic acid is very rapidly absorbed. The serum maxima are reached after only 30 minutes; 2-ethoxybenzoic acid is still detectable in the serum even after 24 hours. These properties make 2-ethoxybenzoic acid an ideal analgesic which has a rapid onset of action and which has no effect on blood coagulation. Since the bioavailability is higher, it is also possible to reduce the single doses. By virtue of the physicochemical properties of 2-ethoxybenzoic acid, use in the form of a solution is possible so that, besides solid drug forms for oral and rectal use, it is also possible to prepare and use liquid formulations such as solutions for administration as drops or by injection.
