The invention generally relates to a pharmaceutical composition for oral administration, containing, as active principle, a benzofuran derivative having antiarrhythmic activity, in particular dronedarone and the pharmaceutically acceptable salts thereof, and at least one lipid carrier, said pharmaceutical composition being intended to be used in a dosage form of the capsule type, in particular with a hard shell. This pharmaceutical composition and the dosage form comprising such a composition aim to limit the meal effect following oral administration in humans. The lipid carrier allows: the solubilisation of the active principle of the invention; and the shielding thereof from the negative effects of pH in the intestinal tract, thereby allowing same to be spared from the meal effect to a significant extent.
