The invention relates to the use of a pharmaceutical composition in combination with a tube food provided for artificial feeding in the treatment of digestive disorders in case of artificial feeding, where the pharmaceutical composition contains or consists of at least one digestive enzyme, preferably a lipase, particularly preferably a bacterial lipase, most preferably burlulipase (INN) in liquid dosage form, wherein the pharmaceutical composition and the tube food are formulated for being administered simultaneously but separately from each other. The pharmaceutical composition can therefore be administered simultaneously and continuously during the administration of the tube food, but separately from it. As a result, the digestive performance of a patient being artificially fed can be enhanced significantly.
