What is the Origin of Fasted Dosing?

The concept is a core tenet of clinical pharmacology and pharmacokinetics, the science that studies the movement of drugs within the body. Standardizing the fasting state is a necessary methodology used in pharmaceutical development and clinical trials to establish a reliable and reproducible dosing protocol. The term emphasizes the deliberate control over the nutritional state to ensure consistent drug delivery.

What is the Mechanism of Fasted Dosing?

The mechanism relies on the absence of complex fats, proteins, and carbohydrates in the digestive tract, which can otherwise physically or chemically interfere with the dissolution and absorption of the administered substance. A fasted state ensures a consistent gastric pH and a predictable, accelerated rate of gastric emptying into the small intestine, the primary site of absorption. This controlled, rapid delivery leads to a more reliable peak plasma concentration, improving both the safety and efficacy of the therapeutic regimen.

Fasted Dosing

Meaning

Fasted dosing is a specific clinical protocol where a pharmaceutical agent, nutritional supplement, or hormone preparation is administered to an individual following a defined period of caloric restriction, typically an overnight fast of eight to twelve hours. The primary objective is to standardize the gastrointestinal environment, which minimizes the pharmacokinetic variability introduced by food and optimizes the compound’s absorption and systemic bioavailability. This precise timing is essential for medications where the presence of food significantly alters the drug’s uptake profile.
