The present invention relates to stable oral benzimidazole compositions and processes for their preparation. The stable oral benzimidazole pharmaceutical composition includes a core, a separating layer, and an enteric coating. The core includes a benzimidazole compound, a substantially water-soluble material and, optionally, one or more pharmaceutically acceptable excipients, wherein the core is not alkaline. The separating layer surrounds the core and includes a substantially water-soluble material and, optionally, one or more pharmaceutically acceptable excipients.
