PT141
is a melanocortin agent that can be used to stimulate the central
nervous system in animals without having to directly affect the vascular
system. Researchers hope to better determine proper levels of
administration for this chemical so it can one day replace products such
as Cialis, Viagra or other phosphodiesterase-5 inhibitors (PDE-5
inhibitors) that are known to exhibit potentially dangerous side
effects.
Unlike
PDE-5 inhibitors, PT141 has not yet been approved for use in men or
women. Ongoing studies are comparing the effects of both classes of
chemicals on a variety of animal subjects to better understand their
effects on different organ and tissue symptoms. There is not yet an
approved dosing that is considered safe for use.
