Abstract
A galenic formulations are disclosed with programmed release, to be administered orally containing as the active ingredient a compound having antiphlogistic, analgesic and antipyretic activity like, for instance, an arylacetic or an arylpropionic acid, and pharmaceutically acceptable salts thereof. In these new formulations, a portion of the active ingredient is released in a short time, so that the drug can quickly develop its therapeutic action and reach the necessary hematic levels, while the remaining portion of the active constituent is released in a longer interval of time so as to allow therapeutic coverage until subsequent administration. The therapeutic coverage can even last twenty-four hours. Thus, the new galenic formulations object of the present invention are suitable for administration one a day.
