PDE5 inhibitor-see above-same
Mechanism of Action:
Same as Sildenafil but there are differences in the Pharmacokinetics(Pk data). Basically, Sildenafil onset of action is quicker (average of 60min) vs Tadalafil onset of action (2hours average). However, Tadalafil lasts longer and stays “in your system” for an average of about 36 hours. You can clearly see the difference below.
