Penetro is a medication used to treat erectile dysfunction in men. Each tablet contains 10mg of Vardenafil, an active ingredient that belongs to a class of drugs known as phosphodiesterase type 5 inhibitors. Vardenafil works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection. This medication should be taken as directed by a healthcare provider, typically about 30 minutes before sexual activity. It is important to note that sexual stimulation is still required for the medication to work effectively. Penetro has been clinically proven to be effective in treating erectile dysfunction and improving sexual performance.
