The changing face of health care, caused by economic constraints, has brought about a new emphasis on the use of outpatient therapy in the treatment of many illnesses. Nutritional support of patients at home is becoming more common, as hospital stays and inpatient services are constantly curtailed. With the shift in emphasis to outpatient care, the role of community pharmacists in nutritional support is expanding. The increasing variety of nutritional supplements available for both oral and tube feeding presents pharmacists with a challenge to update their knowledge of the wide range of products, so they can assist their patients in choosing the most appropriate supplement, and also help patients in dealing with any problems that might arise. This article defines and classifies many of the nutritional feeding products available on the Canadian market today.
