ABOUT COBRA 120:

 is one of the most popular sildenafil generics on the market that is used to cure male sexual problem erectile dysfunction. The medicament is suitable for treating the first signs of impotence. The active ingredient of COBRA 120mg is 120 mg of sildenafil citrate. It belongs to the class of medicines known as PDE-5 inhibitors. Sildenafil increases blood flow to the penis following sexual stimulation and does this by blocking the enzyme responsible for cGMP breakdown.

HOW COBRA 120 (Sildenafil Citrate) WORKS?

Sildenafil Citrate blocks the action of an enzyme known as cGMP-specific phosphodiesterase type-5 (PDE-5). This enzyme breaks down cGMP, a substance that induces smooth muscles to relax. Blocking PDE-5 means increased levels of cGMP within the smooth muscles which promotes muscle relaxation and vasodilation (a widening of blood vessels). High levels of PDE-5 are found in the penis, lungs, and retina. PDE-5 is also found throughout the body within the smooth muscle cells of blood vessels and muscles.

It does this by blocking the enzyme responsible for the breakdown of cGMP. cGMP is a substance that relaxes and widens blood vessels and smooth muscle cells. This allows men to keep an erection hard enough for sex. Sildenafil Citrate only works following sexual stimulation. It works within 30 to 60 minutes, but it can be taken up to four hours before sexual activity.
