Drug Delivery: Enteral Route
0 Views •
2024
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs. Drugs in...

The enteric nervous system (ENS) is a network of neurons and glia located in the gut wall that controls intestinal reflexes. This protocol describes methods for recording the activity of enteric neurons and glia in live preparations of ENS using Ca2+ imaging.

Physiology of Enteric Nervous System and Gut Health

The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...

Enteric Nervous System: Regulation of GI Motor Activity

2024
The Enteric Nervous System (ENS) plays a pivotal role in regulating gastrointestinal or GI motor activity. This complex network of nerves, deeply embedded within the gut wall, responds to changes in the gut environment and receives input from both the autonomic nervous system and the central nervous system. By doing so, the ENS operates various programs tailored to the body's nutritional status and needs. During periods of fasting, the ENS initiates the migrating myoelectric complex, a program...

Preparing and Administering Enteric Tube Medications

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT An enteric tube is a tube that is inserted and passed into the stomach or intestines. Enteric tubes serve multiple purposes, including stomach decompression (through the removal of air, gastric contents, and secretions), enteric feeding, and/or the administration of medications or oral contrast. Enteric tubes are indicated for patients with impaired swallowing and for patients with...
FAQs
Once delivered material reaches the stomach or intestine, digestion can break it down before absorption across the intestinal epithelium. Absorbed components then enter systemic circulation, linking gastrointestinal processing to clinical availability. This sequence explains why the delivery route alone does not determine exposure; what happens after administration also matters.
Formulation and tube placement can change how much of a nutrient or therapeutic agent becomes available and how well the patient tolerates delivery. Formulation affects the material presented to the gastrointestinal tract, while placement determines where it enters. These variables therefore require attention when clinicians tailor enteral delivery to an individual.
Compared with intravenous delivery, enteral delivery uses the gastrointestinal tract rather than administering material directly through a vein. The route may be chosen when intravenous administration is unnecessary or unsuitable, while still allowing nutrients or therapeutic agents to undergo gastrointestinal processing. Its clinical value therefore includes selecting a route that fits the patient's circumstances.
Clinical planning begins by identifying whether oral intake can provide the needed material or whether a feeding tube is appropriate. The selected route then delivers nutrition, medication, or a specialized diet to the gastrointestinal tract. Clinicians must also account for tube placement, formulation, dose availability, and tolerance when organizing administration.
Enteral delivery can support patients who cannot meet nutritional requirements by mouth, making it relevant to nutritional support rather than only medication administration. It can also carry therapeutic agents and specialized diets. The same broad route therefore accommodates different clinical goals, with the delivered material selected according to the patient's treatment or nutrition needs.
In clinical care, preserving gastrointestinal function is an important reason to consider this approach when it is appropriate. Delivery through the gastrointestinal tract supports digestion and absorption while providing a practical alternative to intravenous delivery. It can also guide individualized treatment by combining route choice, formulation, placement, and the intended nutritional or therapeutic outcome.
