Delayed Drug Release Films Based on MIL-100(Fe) Metal-Organic Framework

Biocompatible metal-organic framework MIL-100(Fe) was used as a container for a model hydrophobic active pharmaceutical ingredient, ibuprofen, in composite films based on gelatin, pectin, and kappa-carrageenan. According to powder X-ray diffraction and scanning electron microscopy data, the metal-organic framework retained the crystal structure and its particles were uniformly distributed throughout the hydrocolloid matrix. Testing of the obtained film materials under simulated biological conditions using chromatography–mass spectrometry analysis showed that they are applicable as a dosage form for slow release of active pharmaceutical ingredients.
