The present disclosure relates to a composition, for an orally administered formulation, containing a GLP-1 analogue and, particularly, to a pharmaceutical composition for oral administration comprising a hydrophobic ion-pair of a GLP-1 analogue and an oil phase, and a method for preparing the composition. The pharmaceutical composition for oral administration of the present disclosure forms an emulsion surrounding the hydrophobic ion-pair when exposed to a water phase, so as to be stably absorbed without being decomposed by means of digestive enzymes, and thus provides a pharmacological effect. Therefore, the present disclosure may be utilized as a pharmaceutical composition for oral administration.
