Unlike Cialis, vidalista 20 has a longer duration of action that lasts up to 36 hours. This is why it has been a popular option among men looking for an ED solution that can last. It is also an effective treatment for erectile dysfunction in patients suffering from Benign Prostatic Hyperplasia (BPH). The drug works by connecting muscles and expanding blood flow to the penis. This makes it easier for the body to create an erection. However, it won’t work without sexual stimulation. A tablet of vidalista should be taken 30 minutes before sexual intercourse, and should be placed under the tongue. It is absorbed into the bloodstream sublingually and begins to work within 30 minutes.
