Tadalafil belongs to a group of medications called phosphodiesterase-5 (PDE5) inhibitors. It works by relaxing muscles in the blood vessels of the lungs and penis.
This relaxation increases blood flow to these areas. In the context of erectile dysfunction, increased blood flow to the penis facilitates an erection. For pulmonary hypertension, it improves blood flow to the lungs, easing breathing.
Specifically, Tadalafil inhibits the PDE5 enzyme. This enzyme normally breaks down cyclic guanosine monophosphate (cGMP), a molecule that plays a key role in blood vessel relaxation. By blocking PDE5, Tadalafil allows cGMP levels to rise, leading to vasodilation.
The duration of Tadalafil’s effect varies, but it generally lasts longer than other PDE5 inhibitors. This extended duration is a key difference and often a benefit for many users.
Remember, it’s crucial to consult a healthcare professional before starting any medication, including Tadalafil. They can assess your individual needs and determine the appropriate dosage.
