much enhanced penetration and permeation of pharmaceutically active substances through the skin barrier
creation of a drug depot guaranteeing a long-term effect at the target site and thus reducing the frequency of dosing and the total treatment time
improved benefit/risk ratio (reduction in side-effects by prevention of toxic plasma concentrations)
higher product safety by more accurate dosage, due to the more exact spray system
rapid penetration of the whole formulation into the skin without leaving a residual fatty surface film (making surgical dressing unnecessary)
no need for additional gelling substances, known to inhibit drug penetration
no need for additional preserving substances, causing further problems in patients with allergies
no gastro-intestinal or hepatic first-pass effects
minimal risk of gastro-intestinal side-effects
