Filitra 40 mg is a medication primarily used to address erectile dysfunction (ED) in men. Erectile dysfunction is a condition characterized by the inability to achieve or maintain a firm and lasting erection during sexual activity. Filitra 40 mg contains Vardenafil as its active ingredient, which falls under the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. These drugs work by enhancing blood flow to the penis, allowing men to achieve and sustain an erection when sexually aroused.
