- Mechanism of action: Inhibits phosphodiesterase type 5 (PDE5) in smooth muscle.
- PDE5 breaks down cyclic guanosine monophosphate (cGMP).
- Sexual stimulation releases nitric oxide (NO), which increases cGMP.
- cGMP causes smooth muscle relaxation in the corpus cavernosum of the penis.
- This relaxation allows increased blood flow and an erection.
- By inhibiting PDE5, tadalafil increases cGMP levels, enhancing the erectile response.
- In BPH/urinary tract, relaxation of prostate and bladder smooth muscle improves symptoms.
- In PAH, vasodilation occurs in the pulmonary vascular bed.
- It has minimal effect on PDE6 (retina) compared to sildenafil, possibly fewer visual effects.
