Vardenafil (Levitra) Research — Connecticut
Vardenafil (Levitra) is a PDE5 inhibitor — highest PDE5 selectivity among first-gen PDE5i researched for PDE5 Selectivity Research, Erectile Function / Haemodynamic Research, Diabetes-Associated ED Research. QSC ships Vardenafil domestically to Connecticut with Janoshik third-party COA verification.
Vardenafil is a piperazinylsulfonyl pyrimidinone PDE5 inhibitor with the highest in vitro potency and PDE5/PDE6 selectivity ratio of the first-generation PDE5 inhibitors. IC50 for PDE5: ~0.7 nM (vs ~3.5 nM sildenafil). Greater PDE5 selectivity over PDE6 (retinal phosphodiesterase) vs sildenafil reduces photophobia and colour vision adverse events — relevant for dose-escalation … Full Vardenafil Research Hub →
