 Gamma scintigraphy images at 15 min post intranasal administration of quetiapine loaded (a) nanoparticles (QNP), (b) mucoadhesive microemulsion (QMME), (c) microemulsion (QME), (d) drug solution (DS) and intravenous administration of quetiapine loaded (e) microemulsion (QME) and (f) nanoparticles (QNP). Among intranasal formulations, QMME represents highest radioactivity in the rat brain which is followed by QNP, QME and DS, while intravenous formulations (e and f) did not reveal sufficient radioactivity in the rat brain
