Cenforce 130 mg works by blocking the PDE5 enzyme, allowing blood vessels in the penile region to relax more effectively. This increases blood flow and helps achieve and maintain an erection when a man is sexually aroused. It does not cause an erection on its own and requires sexual stimulation to work. This dosage is considered above the commonly prescribed standard range (usually 25 mg to 100 mg), so it is generally used only when lower doses are not effective and only under medical supervision. It is typically taken about 30 to 60 minutes before sexual activity, and its effects may last around 4 to 6 hours. https://www.genericday.com/cenforce-130-mg.html
