5 Pharmacology and Biochemistry
5.1 Pharmacology

Vomeropherin compounds are directly delivered to the nasal passages using either a metered nasal spray or a metered nasal aerosol. By virtue of the chemoreceptors location in the nasal passages, direct connections to the hypothalamus and limbic system and the ability of our compounds to act locally, vomeropherins do not need to achieve systemic absorption and distribution. This provides a significant therapeutic advantage over traditional therapeutics targeted at the hypothalamus and limbic system that require access to systemic circulation and must cross the blood-brain barrier followed by uptake into the brain to exert effects.


5.2 Absorption, Distribution and Excretion

Absorption

Absorbed following nasal administration.


5.3 Mechanism of Action

There is little information available on the mechanism of action of vomeropherins. These compounds are delivered to the nasal passages and bind to chemoreceptors that in turn affect the hypothalamus and the limbic system.
