Cialis contains tadalafil, a phosphodiesterase-5 (PDE5) inhibitor. This means it works by relaxing blood vessels in the penis, increasing blood flow.
Here’s a breakdown of the process:
Sexual stimulation triggers the release of nitric oxide. Nitric oxide activates an enzyme called guanylate cyclase. Guanylate cyclase produces cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscles in the blood vessels of the penis. Tadalafil inhibits PDE5, preventing the breakdown of cGMP. Increased cGMP levels sustain the relaxation of blood vessels, leading to an erection.
Unlike some other medications, tadalafil’s effects can last for up to 36 hours, offering a longer window of opportunity for sexual activity. This extended duration is a key differentiator.
Remember to consult a doctor before using Cialis or any medication to ensure it’s safe and appropriate for your individual health needs. They can assess potential interactions with other medications and discuss potential side effects.
- Proper diagnosis is crucial. Dosage should be tailored to individual requirements. Consult your physician regarding any concerns.
