Tadalafil, the active component of Vidalista, improves blood flow to the penis by relaxing the muscles in the penile blood vessels, thereby treating erectile dysfunction. Pulmonary hypertension can potentially be cured by facilitating easier blood flow via the arteries in the lungs. Because these factors may alter how effectively your medication works, please let your doctor know if you smoke, use illegal substances, consume alcohol or caffeinated beverages, or any combination of these. When a medication is taken with food or another medication, medicine interactions usually occur.
