By blocking the phosphodiesterase type 5 (PDE5) enzyme, Zudena 100 mg tablet (udenafil) helps to relax blood vessels and enhance blood flow to the penis. Men can attain and sustain a hard erection during sexual stimulation thanks to this improved blood circulation.
Zudena is more effective for up to 12 hours, which is longer than some other ED drugs. For best effects, take it 30 to 60 minutes before sexual activity. Nevertheless, it doesn't boost libido and needs sexual stimulation to function.
