Cialis contains tadalafil, a phosphodiesterase-5 (PDE5) inhibitor. This means it works by relaxing blood vessels in the penis, increasing blood flow and facilitating an erection.
Specifically, tadalafil inhibits the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). Higher levels of cGMP promote smooth muscle relaxation, leading to vasodilation.
Sexual stimulation triggers the release of nitric oxide, which in turn increases cGMP levels. Tadalafil enhances this effect, allowing for a stronger and more sustained erection in response to sexual stimulation.
Unlike some other medications, tadalafil’s longer half-life means its effects can last up to 36 hours. This extended duration differentiates it from other PDE5 inhibitors.
Remember to consult your doctor before starting Cialis, particularly if you have underlying health conditions or are taking other medications. They can assess your suitability for the drug and advise on appropriate dosage.
