Cialis- helping millions to solve ED

By: Antony Virgese

Introduction

If you have an impending nightmare of erectile dysfunction it is time you start considering Cialis. The successful treatment of impotence has been demonstrated to improve intimacy and satisfaction, improve sexual aspects of quality of life as well as overall quality of life, and relieve symptoms of depression.

The complex process of erection

For a man to have an erection a complex process takes place within the body.

• Erection involves the central nervous system, peripheral nervous system, psychological and stress-related factors, local problems with the erection bodies or penis itself as well as hormonal and vascular (blood flow or circulation) factors. The penile portion of the process leading to erections represents only a single component of a very complicated and complex process.

• Erections occur in response to touch, smell, and visual stimuli that trigger pathways in the brain. Information travels from the brain to the nerve centers at the base of the spine, where primary nerve fibers connect to the penis and regulate blood flow during erection and afterward.

• Sexual stimulation causes the release of chemicals from the nerve endings in the penis that trigger a series of events that ultimately cause muscle relaxation in the erection bodies of the penis. The smooth muscle in the erection bodies controls the flow of blood into the penis. When the smooth muscle relaxes, the blood flow dramatically increases, and the erection bodies become full and rigid, resulting in an erection. Venous drainage channels are compressed and close off as the erection bodies enlarge.

• Detumescence (when the penis is no longer in a state of erection) results when muscle-relaxing chemicals are no longer released. Ejaculation causes the smooth muscle tissue of the erection bodies in the penis to regain muscle tone, which allows the venous drainage channels to open and the blood drains from the penis.

Cialis intervention helping millions to fight with ED effectively

Tadalafil is a drug used to treat male erectile dysfunction (impotence). In the United States, tadalafil has Food and Drug Administration approval and became available in December, 2003 as the third pill after Viagra and Levitra. Due to its 36-hour effect it is also known as the "Weekend Pill". It was developed by the biotechnology firm ICOS and marketed worldwide by Eli Lilly and Company under the brand name Cialis.

It is in a class of drugs called phosphodiesterase inhibitors that also includes sildenafil (Viagra) and vardenafil (Levitra). Erection of the penis is caused by the filling of the penis with blood. Filling occurs because the blood vessels that bring blood to the penis increase in size and deliver more blood to the penis, and, at the same time, the blood vessels that take blood away from the penis decrease in size and remove less blood from the penis.

Sexual stimulation that leads to an erection causes the production and release of nitric oxide in the penis. The nitric oxide causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP). It is the cGMP that is primarily responsible for increasing and decreasing the size of the blood vessels carrying blood to and from the penis, respectively, and causing the erection. When the cGMP is destroyed by another enzyme, phosphodiesterase-5, the blood vessels return to their normal size, blood leaves the penis, and the erection ends. Tadalafil prevents phosphodiesterase-5 from destroying cGMP so that cGMP stays around longer. The persistence of cGMP leads to a more prolonged engorgement of the penis with blood.
Tadalafil was approved by the FDA in November, 2003.

Conclusion

Since oral drugs like Cialis are not exactly recommended to all and are sold as prescription medicines only, it will be wise not to mess around with the medication of this drug. Always consider yourself getting thoroughly checked by an expert doctor, or share your complete medical history with your doctor, before you go buying Cialis online.
