Source-derived summary

Avanafil is a PDE5 inhibitor approved for erectile dysfunction by the FDA on April 27, 2012 and by EMA on June 21, 2013. Avanafil is sold under the brand names Stendra and Spedra. It was invented at Mitsubishi Tanabe Pharma, formerly known as Tanabe Seiyaku Co., and licensed to Vivus Inc., which partnered with Menarini Group to commercialise Spedra in over forty European countries, Australia, and New Zealand. Metuchen Pharmaceuticals obtained exclusive rights within the United States.

Avanafil acts by inhibiting a specific phosphodiesterase type 5 enzyme found in various body tissues, primarily in the corpus cavernosum penis. Other similar drugs are sildenafil, tadalafil and vardenafil. The advantage of avanafil is that it has very fast onset of action compared with other PDE5 inhibitors. It is absorbed quickly, reaching a maximum serum concentration in about thirty to forty-five minutes. About two-thirds of the participants were able to engage in sexual activity within fifteen minutes.

Medical use

Avanafil is used to treat erectile dysfunction (ED).

Editorial summary

This brief starts where responsible research should: with the source description of “Avanafil” as chemical compound. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—2012, 2013—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Avanafil, chemical and compound can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as chemical compound. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q2873270. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2012 and 2013.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
