Cialis 20mg 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 PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP). Higher cGMP levels lead to smooth muscle relaxation in the penis.
Sexual stimulation is still required to initiate the process. Cialis doesn’t create spontaneous erections; it enhances the body’s natural response to sexual arousal.
The effects of a 20mg dose typically last up to 36 hours, significantly longer than other PDE5 inhibitors. This extended duration allows for more flexibility in timing sexual activity.
Remember to consult a doctor before using Cialis, particularly if you have pre-existing health conditions, such as heart problems or high blood pressure.
Always follow prescribed dosage instructions. Misuse can lead to adverse effects. Discuss potential side effects and drug interactions with your physician.
