Pharmaceutical compositions and methods for enhancing targeting of therapeutic compounds to, inter alia, the CNS applied via intranasal administration while reducing non-target exposure are provided. In certain embodiments, at least one vasoconstrictor is provided intranasally prior to intranasal administration of at least one therapeutic compound. In other embodiments, the vasoconstrictor(s) and therapeutic compound(s) are combined in a pharmaceutical composition and delivered intranasally. The present invention substantially increases targeting of the therapeutic compound(s) to, inter alia, the CNS while substantially reducing unwanted and potentially harmful systemic exposure. The preferred administration of the invention applies the vasoconstrictor(s) and/or therapeutic compound(s) to the upper third of the nasal cavity, though application to the lower two-thirds of the nasal cavity is also within the scope of the invention.
