Cialis tablets is the brand name for the anti-impotence medication tadalafil. Essentially they function as a phosphodiesterase type 5 (PDE-5) inhibitor. This basically means that they can block the degenerative activity of cyclic guanosine monophosphate (cGMP). When a man is sexually aroused, nitric oxide is sent to his sexual organ. This prompts the enzyme guanylate cyclase to synthesize cGMP.
The latter of which is responsible for controlling the appropriate dilation and contraction of the blood vessels found within the soft tissues of the male sexual organ. However, the presence of PDE-5 usually goes on to destroy cGMP , making these blood vessels to remain in their normal size even after a man is sexually stimulated.
Cialis tablets therefore work by blocking this detrimental activity of PDE-5, and stops it from destroying cGmp. This results in a stiffer erection that is characterized by a prolonged duration. This medication was first approved by the FDA as a viable treatment for erectile dysfunction in late November 2013. Users are instructed by its maker to take this pill when needed, but they are also warned against exceeding a dosage of more than one tablet per day. For this drug to work, the user must first be sexual excited otherwise they will fail to achieve a satisfactory erection.
Cialis tablets are made available in yellow, almond shaped pills of either five, ten or twenty milligrams doses. This anti-impotence medication has over the years gone on to earn the epithet of the “weekend pill” which arises from the fact that its effects are known to last for up to thirty six hours. Which is a significantly longer duration than the eight hours of similar drugs such as Viagra and Levitra.
When it comes to side effects, this medication has been reported to rarely adversely influence blood circulation in the optic nerve, which can trigger sudden loss of vision. This side effect risk factor is usually enhanced when the user has a history of high blood pressure, heart disease, high cholesterol levels or existing eye related problems.
Individuals that have the following health challenges are advised not to use Cialis tablets without consulting their physicians. This includes those that have heart rhythm issues, congestive heart failure, stroke, blood cell disorders, hemophilia, liver or kidney disease, stomach ulcers and heart disease. Those individuals who may have been forced to discontinue sexual intercourse for health related reasons should also obtain approval from their doctors before using this anti-impotence drug.
