Abstract Microneedles (MNs) have been investigated as a minimally-invasive delivery technology for a range of active pharmaceutical ingredients (APIs). Various formulations and methods for coating the surface of MNs with therapeutics have been proposed and exemplified, predominantly for hydrophilic drugs and particulates. The development of effective MN delivery formulations for hydrophobic drugs is more challenging with dosing restrictions and the use of organic solvents impacting on both the...
