AbstractBecause of easiness and accessibility, the oral route of administration is usually the route of choice for medication delivery, as long as the oral drug form is available and the patients' circumstances allow it.In patients admitted to the intensive care unit this route is frequently altered. This provokes difficulties in swallowing and consequently an enteral feeding catheter must be inserted to supply the patient's nutritional requirements. This catheter is also used for the drug administration, which necessitates opening capsules or crushing pills before dilution. When added to drug-nutrient interactions, this process alters the drug's properties and modifies its pharmacokinetic profile, its pharmacological effect and the intensity of side effects. It can also provoke catheter obstruction. The aim of this study was to establish guidelines for drug administration through enteral feeding catheters. We provide a thorough review of the literature, describe oral drug forms, present a protocol for correct drug administration and provide a guide to the most commonly used drugs in our unit. For each of these drugs we include recommendations on administration and possible alternatives.
