Valif 20 Mg is a medication designed to treat ED by increasing blood flow to the penis, thereby helping a man achieve and maintain an erection during sexual activity. Its active ingredient, Vardenafil, works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. By blocking this enzyme, Valif 20 Mg allows for enhanced blood circulation, making it easier for men to achieve a firm and lasting erection.
