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 T_max at 1 h and a half-life of 3–5 h. Vardenafil is somewhat similar with a T_max 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 T_max 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.

Avanafil was originally discovered at Tanabe Seiyaku (now Mitsubishi Tanabe). JW Pharmaceutical (previously Choongwae Pharma) and VIVUS have since developed and launched avanafil, which is an oral PDE5 inhibitor for the treatment of erectile dysfunction (ED). Although many marketed PDE5 inhibitors (e.g. sildenafil, vardenafil and tadalafil) are available for the treatment of ED, many patients are still unable to achieve the desired results and experience undesired side-effects with these existing medications. As such, second-generation PDE5 inhibitors with enhanced PDE5 selectivity, shorter systemic half-lives, and improved tolerability are desired. Developed to meet these criteria, Avanafil exhibited good oral bioavailability and PDE5 selectivity in both preclinical studies and clinical trials. Avanafil had a short onset of action (35 min) and short half-life (1.5 h).

Avanafil is metabolised in the liver mainly by the cytochrome P450 isoenzyme CYP3A4 and to a minor extent by the CYP2C isoform. Two major metabolites are produced, one of which is active. Avanafil is excreted as metabolites mainly in the faeces (approximately 63%) in the urine (approximately 21%).
