Abstract:
Medication administration via enteral feeding tubes (EFT) is a necessary practice for patients unable to swallow oral dosage forms due to a medical condition or treatment that affects the ability to swallow or the function of the gastrointestinal tract. Off-label administration of oral drug products via EFT raises concerns for pharmaceutical sponsors, regulators, and healthcare practitioners (HCPs) because of the potential risks this practice introduces to both the patient and the caregiver. These risks can be mitigated by generating data-supported instructions that patients and HCPs can use to ensure safe and accurate administration of oral drug products via EFT. This commentary presents an industry perspective on the testing that should be conducted to enable development of product-specific instructions in the labeling to support or advise against administration of oral drug products via enteral feeding tube. The proposal outlined in this commentary takes a risk-based approach, addressing recommendations from both regulatory agencies as well as considerations for expanding this testing to address needs specific to neonatal and pediatric populations.

Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...
Routes of Drug Administration: Enteral
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...

Methods for Studying Drug Absorption: In vitro
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...
Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
