The chemical messenger secreted when a man is s*xually active is known as cyclic GMP. It relaxes and dilates the blood vessels in the male s*xual organ, the p*nis. It allows more blood to flow in. This is the reason for the firmness and erection of the p*nis. Cyclic GMP is usually broken down by an enzyme in the human body called phosphodiesterase type 5. Slide 100 can work by preventing this enzyme from breaking down cyclic GMP. It helps the blood vessels in the p*nis to be over-stretched for a long period, increases blood flow to the p*nis and helps in achieving and maintaining an erection. This pill is taken with or without food. Patients are advised to swallow the pill whole with a glass of water. After taking this medicine, a man can have an erection for almost 4 to 5 hours. It is suggested that a man takes Cenforce 100 mg 30 to 50 minutes before having s*x to give him a specific time to achieve the desired level of results. Do not chew, break or crush the tablet. Taking it with food will keep it active for longer.
