Simulated digestion: Nanomaterial made from lipids and silicon dioxide improves absorption of pharmaceuticals

Some medicines have to be taken either before, after, or during a meal because food ingredients can affect its absorption or bioavailability. Australian researchers have now encapsulated drugs in a matrix of silicon dioxide and lipids to simulate the administration of pharmaceuticals with food. As the researchers report in the journal Angewandte Chemie, drug absorption is increased through control of the enzymatic digestion of the lipid droplets.  More...
