How does Tadalafil work?
Tadalafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors [1].

Tadalafil (Cialis) is a PDE5 inhibitor, similar to sildenafil (Viagra), vardenafil (Levitra), and avanafil (Stendra) [1]. A key difference often highlighted is tadalafil's longer duration of action, with effects potentially lasting up to 36 hours [1].
