What is Vardenafil?
Vardenafil is a potent, selective PDE5 inhibitor with higher PDE5 affinity and greater selectivity over PDE6 than sildenafil, providing potentially fewer visual side effects. Studied for PDE5 pharmacology, erectile physiology, cGMP pathway research, and comparative PDE5 inhibitor pharmacology. Research use only.
Research Applications
PDE5 Inhibition Pharmacology
High-affinity PDE5 inhibition — IC50, selectivity profile, cGMP elevation
Comparative PDE5 Research
