Product Description

The human body is a remarkable chemical factory. It produces a vast range of different chemicals for different purposes all around the body. One of the most important things a body must be able to do is move around. As activity levels rise, the muscles need more oxygen so blood vessels dilate to carry more oxygen-rich blood to the muscles. This dilation and subsequent contraction process depends on the production and delivery of phosphodiesterase. This chemical messenger comes in different types depending on the position of the muscle group in the body. To get the blood vessels to dilate and contract properly into and out of the penis relies on phosphodiesterase type 5, usually shortened to PDE5. As an aside, PDE5 is also used in the lungs and cialis can be used to treat pulmonary hypertension by ensuring the smooth flow of blood into and out of the heart.

One of the challenges for the manufacturer during the development stage was to make cialis specific to the penis. Because PDE is quite a common chemical in the body, the risk is that what is intended only to affect PDE5 may also affect one of the other types. Hence, one of the less common side effects to cialis is that eyesight can be affected. This is because PDE6 works inside the retina. All the manufacturers are working hard to make their drugs “super selective”, i.e. only to affect the “right” type of PDE inside the body. There is good progress being made but, as a safety precaution, you should always use the lowest dosage to achieve the erection. Unwanted side effects become more common if you exceed the recommended dosage. That means monitoring time carefully. You should only take the “weekend” version every thirty-six hours and do not take more than one tablet per day when using the once-daily version.
