Definitions
- the present invention relates to a pharmaceutical composition in tablet form, containing an active ingredient, used for administration once a day.
- the conventional sustained-release dosage forms are hardly suitable for certain active principles which have an absorption window in the upper parts of the gastrointestinal tract, that is to say which are absorbed in the stomach, the upper parts. small intestine, duodenum, jejunum and ilium, and less or less at the colonic level. Indeed, the conventional administration unit releases the active substance throughout its passage in the gastrointestinal tract and not only in the part where the absorption of the active ingredient is maximum.
