Longer-lasting pain relief with MOFs

To treat headaches, back pain or fever, most of us have reached for ibuprofen at one point or another. But we often have to take doses every four to six hours if the pain warrants it. Now scientists are working on a way to package the commonly used drug so it can last longer. Their approach, reported in ACS’ journal Molecular Pharmaceutics, could also be used to deliver other drugs orally that currently can only be taken intravenously.

Recently, scientists have been studying compounds called metal-organic frameworks (MOFs), which are made of metal ions linked to organic ligands, for drug delivery. Active ingredients can be packed inside MOFs, which are porous, and some of them have additional traits such as water solubility that make them good candidates for drug couriers. But few studies have so far investigated whether such MOFs could be used in oral formulations. J. Fraser Stoddart and colleagues wanted to test promising MOFs using ibuprofen as a model drug.
