Vardenafil, the active ingredient in Filitra 10, works by inhibiting the action of the enzyme phosphodiesterase type 5 (PDE5). This inhibition leads to increased blood flow to the penis, which helps in achieving and sustaining an erection during sexual stimulation. The effects of Filitra 10 can last for about 4 to 6 hours, providing a suitable window of time for sexual activity. It's important to note that the medication does not cause spontaneous erections and requires sexual stimulation to be effective.
