How long it takes sildenafil to remain active in your body depends on several factors. This includes your age, diet, and existing health conditions. It also depends on the dosage of sildenafil you take.

Black Viagra Pills Cenforce 200 is an erectile dysfunction (ED) medication that helps to increase blood flow in your penis. It works by blocking an enzyme called phosphodiesterase type 5 (PDE5), which breaks down certain messengers that are responsible for getting and maintaining an erection.

PDE5 inhibitors like Viagra work by relaxing muscles in the blood vessel walls to improve blood flow, which makes it easier for you to get an erection. In addition, Viagra increases the amount of a key substance called cGMP in your penis that’s needed to achieve and maintain an erection. Getting an erection is a complex physiological process, which involves many systems in your body. A lot has to be right for it to occur – including your mood, sex drive, and the amount of sexual stimulation you receive.
