Rationale 1: Oligomeric formulations are agents containing varying slightly larger molecules such as free amino acids and peptide combinations that require little or no digestion.
Rationale 2: Polymeric formulations are the most common enteral preparations. These products contain various mixtures of proteins, carbohydrates, and lipids and are used in patients who are generally undernourished but have a fully functioning GI tract.
Rationale 3: Elemental or monomeric formulas include products that are usually lactose free and contain a small percentage of calories from fats.
Rationale 4: Modular formulations contain a single nutrient, protein, lipid, or carbohydrate.
