Tablets called Cenforce 130 are prescribed to treat erectile dysfunction (ED). The inability to achieve or sustain an erection is known as ED. When you are excited sexually, cenforce tablets relax the blood vessels in your penis, allowing blood to flow into it. An erection brought on by the increased blood flow might endure for up to 8 hours. It begins to act thirty minutes after taking it with water and continues to do so for up to twelve hours.
