Description
Avanafil (Zepeed) was approved by the Korean Health Ministry for the
treatment of erectile dysfunction (ED) in August 2011. Avanafil is a
highly selective type 5 phosphodiesterase (PDE5) inhibitor.
Avanafil is reported to be the most selective PDE5
inhibitor on the market. The onset of Tmax and half-life also varies among
the marketed PDE5 inhibitors. Sildenafil has a Tmax at 1 h and a half-life of
3–5 h. Vardenafil is somewhat similar with a Tmax of 0.6 h and a half-life of
4–6 h. Tadalafil has the longest half-life among the marketed drugs with a
half-life of 17 h. Avanafil has a fast onset of action reaching Tmax in 0.6 h
with a half-life of 1.2 h. A synthesis of avanafil (TA-1790) is described
in the patent literature. The main elimination route of avanafil
is through the bile and feces. Avanafil was also found to be reabsorbed
through enterohepatic recirculation.
