The reason Kamagra is so effective is due to its active ingredient, a chemical compound called sildenafil citrate. Sildenafil citrate, also present in Viagra, belongs to a group of medications known as PDE-5 inhibitors. When a man becomes sexually aroused, two enzymes are produced, cyclic GMP and PDE-5. Cyclic GMP is responsible for producing erections, whereas PDE-5 blocks cyclic GMP from working effectively. When sildenafil citrate is introduced, PDE-5 is inhibited, allowing cyclic GMP to flourish. This results in blood vessels expanding, which boosts blood flow to the penis to create a healthy erection.
Some users experience some side effects taking Kamagra tablets. Most often, as with all forms of generic Viagra, the side effects experienced are mild. These can include flushing of the face, nausea, blue tinge to vision, a stuffy nose or headaches. These side effects should subside after the medication has left the body. Very rarely indeed, a more serious side effect may occur called priapism, which is defined as an erection that lasts 4 hours or more without subsiding. In the extremely rare case of experiencing priapism, you are advised to seek medical attention immediately.
