Very commonly known as a blue pill, Kamagra contains a single drug known as sildenafil citrate in a concentration of 100mg. sildenafil citrate acts by increasing the blood supply to the penis and thus improving the duration of an erection. The blood vessels which supply the penis get constricted when the heart rate increases, sildenafil acts by dilating the blood vessels. It also improves the relaxation of the smooth muscles of the penis. They are also known as PDE5 inhibitors as PDE5 prevents an erection. Kamagra tablets take about 30 mins for the onset of action. These are available as over-the-counter drugs. Kamagra 100mg tablets can be taken by men aged between 18-65 years.
