FEDGAS™ dissolution medium simulates human stomach fluid in the fed state. 900ml of medium contains the 62.5g of fat and 62.5g of carbohydrate present in a partially digested, high-fat FDA meal.

Food-effect bioavailability studies (for new drugs) and fed bioequivalence studies (for generic drugs) are mandatory in most cases because food can have a significant impact on how the drug is absorbed. This is important because it can have a profound effect on drug efficacy and even safety in patients. It’s why dissolution tests in FEDGAS are so useful because they can help you understand how the drug is released in the stomach after eating a meal. FEDGAS at pH 6 simulates fluid immediately after food when the stomach is full.

FEDGAS™ Preparation Instructions

bottle scientist with fedgas fedgas bottle

FEDGAS™ dissolution medium simulates human stomach fluid in the fed state. You should use 900ml per USP2 dissolution vessel: this contains the amount of fat and carbohydrate present in a high fat FDA meal.

Equipment

  • Calibrated balance
  • Suitable container
  • Stirrer plate and PTFE magnet

Method

FEDGAS pH 6 simulates fluid when the stomach is full (immediately after a meal). To make 900ml:

  • Weigh 36.8g of FEDGAS Buffer Concentrate (pH6) into a suitable container
  • Add 732.6g of purified water
  • Add 153.0g of FEDGAS gel
  • Stir until mixed thoroughly. The medium will be white like milk and is ready to use

Usage

  • We recommend using FEDGAS dissolution medium at 37⁰C. It can be used for up to 24 hours at this temperature
  • Store the FEDGAS gel pouch in the refrigerator and use within 7 days of opening
  • Store the FEDGAS buffer bottle at room temperature
