The technique and its benefits

Magnetic Marker Monitoring (MMM) is a technique for visualising the transit of a solid oral dosage form through the gastrointestinal tract. Disintegration and drug-release characteristics can also be determined. A precise 3-dimensional localisation with high specific resolution (few millimetres’ precision) can be achieved. The method is based on incorporating small amounts of magnetite (about 1 mg of black iron oxide, E172) into the formulation and subsequent magnetic flux density measurements.

The marker substance magnetite is suitable for IMPDs in the European Union!

When is MMM useful ?

The technique allows different applications during formulation development and also for regulatory purposes:

  • Proof of concept of newly developed modified release formulations including formulations intended for continuous gastric release
  • Tabletwise in-vitro/in-vivo correlations
  • Characterisation of formulation-related food interactions
  • Supportive data for clinical development and regulatory submission of GI-drug targeting

Current status

Our measurement system is currently being changed. We expect to have the new measurement chamber running by autumn this year.
