Radionuclide techniques measure gastric emptying (GE) rates for various contents. Understanding how drugs affect GE is crucial for oral medication bioavailability and gastrointestinal motility.

Area of Science:

  • Gastroenterology
  • Pharmacology
  • Nuclear Medicine

Background:

  • Radionuclide techniques provide quantitative data on gastric emptying (GE) rates.
  • GE rate data are available for basal states and after drug administration.
  • Altered GE can impact the bioavailability of orally administered drugs.

Purpose of the Study:

  • To review the current understanding of gastric emptying physiology.
  • To provide an informational review of drugs affecting GE.
  • To categorize drugs by medical subspecialty and special use.

Main Methods:

  • Review of existing literature on radionuclide techniques for GE assessment.
  • Compilation of data on drug effects on GE.
  • Categorization of drugs based on medical subspecialty and therapeutic use.

Main Results:

  • Radionuclide methods accurately measure GE for liquids, solids, and indigestible contents.
  • Drug administration significantly influences GE rates.
  • Clinical relevance exists for drugs affecting GE, impacting medication bioavailability.

Conclusions:

  • Accurate assessment of gastric emptying is vital for understanding drug absorption.
  • Knowledge of drug-induced GE changes aids in optimizing oral drug therapy.
  • This review categorizes drugs influencing GE for clinical and research applications.
