Viagra, Cialis, and Levitra all stand out as the top contenders. Each of these medications has proven effective, but they differ in dosage, timing, and side effects.
Understanding these differences is crucial in choosing the most suitable medication.
What is Viagra (sildenafil)?
Viagra is a brand-name oral tablet. Viagra contains the active ingredient sildenafil.
Sildenafil (Viagra) is a phosphodiesterase-5 (PDE-5) inhibitor. PDE-5 is a protein in your body that breaks down the molecules that normally cause an erection.
When it blocks PDE-5, sildenafil (Viagra) helps an erection occur by allowing certain muscles in the penis to relax and the penis to fill with blood.
What is Cialis (tadalafil)?
Tadalafil (Cialis) is a phosphodiesterase-5 enzyme (PDE-5) inhibitor. It works by blocking PDE-5. This is a protein in your body that breaks down the molecules that normally cause an erection.
When it blocks PDE-5, tadalafil (Cialis) helps an erection occur by allowing certain muscles in the penis to relax and the penis to fill with blood.
What is Levitra (vardenafil)?
Vardenafil is a medication that treats erectile dysfunction. ED is the inability to achieve and sustain an erection suitable for sexual intercourse. This medication works by increasing blood flow to your penis, which helps you maintain an erection.
