What is Tadalafil?
Tadalafil is a long-acting, highly selective PDE5 inhibitor with a T½ of approximately 17.5 hours — markedly longer than sildenafil (~4h). High PDE5/PDE6 selectivity ratio minimises visual side effects. Research tool for PDE5 pharmacology, BPH research (PDE5 expression in prostate), erectile physiology, and long-duration cGMP studies. Research use only.
Research Applications
Long-Acting PDE5 Inhibition
T½ ~17.5h — sustained cGMP elevation, steady-state receptor occupancy modelling

Minimal PDE6 cross-reactivity vs sildenafil — visual safety mechanism research
BPH & Prostate Research
PDE5 expression in prostate smooth muscle — urinary tract and erectile function
Erectile & Vascular Physiology
Long-duration NO-cGMP pathway amplification, corpus cavernosum biology
