Tableted oral pharmaceutical dosage form, with enteric coating, containing a compound of benzimidazole labile in an acid medium

A tableted oral pharmaceutical dosage form, covered with an enteric coating, consisting of a plurality of units that contain a benzimidazole compound labile in an acid medium as the active principle, comprising:

• (a) A plurality of units containing a benzimidazole compound labile in an acid medium as the active principle that contain:
• i) an inert core;
• ii) an active layer deposited on said inert core i), formed by a benzimidazole compound labile in an acid medium, a non-alkaline water-soluble inert polymer and one or more pharmaceutically acceptable inert excipients;
• and
• iii) an intermediate layer consisting of an inert non-alkaline coating formed by a non-alkaline, water-soluble inert polymer and one or more pharmaceutically acceptable inert excipients, with said intermediate layer being disposed over the aforementioned active layer ii) that covers the inert core i);
• (b) one or more pharmaceutically acceptable inert excipients, of which one or more are compression excipients;
• and
• (c) an enteric coating layer that coats said plurality of units containing a benzimidazole compound labile in an acid medium as the active principle and said pharmaceutically acceptable inert excipients (b).
