ORAL DOSAGE FORMS COMPRISING A BENZIMIDAZOLE AND BUFFER

摘要

The present invention relates to pharmaceutical preparations comprising substituted benzimidazole proton pump inhibitors. There is provided a liquid or solid pharmaceutical dosage form that is not enteric coated or delayed released containing a proton pump inhibitor and a Primary Essential Buffer, and an optional Secondary Essential Buffer. When the dosage form is placed in a liquid phase the Primary Essential Buffer maintains the pH of the environment at a value greater than the pKa of the proton pump inhibitor for a time sufficient to substantially avoid acid degradation of the proton pump inhibitor in the environment. Also provided is a method for treating acid-related gastrointestinal disorders by administering a solid pharmaceutical dosage form; and a kit for the preparation of a liquid oral pharmaceutical composition.
