Tadalafil (the active ingredient in Tadalista Professional) and Sildenafil (the active ingredient in Viagra) both belong to the same drug class called PDE5 inhibitors. This means they work in a very similar way—by increasing blood flow to the penis during sexual stimulation to help achieve and maintain an erection. Key similarities Both treat erectile dysfunction (ED) Both require sexual stimulation to work Both improve blood Tadalista Professional by relaxing blood vessels Both have similar possible side effects (headache, flushing, dizziness, indigestion) Key differences Duration: Tadalafil (Tadalista Professional): lasts up to 24–36 hours Sildenafil (Viagra): lasts about 4–6 hours Onset: Sildenafil may act slightly faster in some users (30–60 minutes) Tadalafil Professional (sublingual) can also act quickly (about 15–30 minutes for some) Food effect: Sildenafil is more affected by heavy fatty meals Tadalafil is less affected by food Simple summary They are not the same ingredient, but they are closely related medicines that work in a similar way. The main difference is that tadalafil tends to last much longer in the body, while sildenafil has a shorter duration but similar effectiveness. If you want, I can compare Tadalista Professional vs Viagra in terms of strength, speed, and side effects in a simple chart.
