Filitra 40 mg is a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Filitra is Vardenafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Vardenafil works by relaxing the muscles and increasing blood flow to the pill during sexual stimulation, helping to achieve and maintain an erection. Filitra 40 mg is taken orally, typically about 25 to 60 minutes before sexual activity. The effects of the medication can last for up to 4 to 5 hours. It is important to note that sexual arousal is required for the drug to be effective—it does not cause an erection on its own. https://www.genericday.com/filitra-40-mg.html
