Cialis or Viagra

sss  Erectile Dysfunction or Impotence is defined as the inability to ensure and maintain an erection sufficient for sexual intercourse. ED affects an estimated 180 million men worldwide . 90 percent of ED cases are related to a physical or medical condition, such as diabetes, cardiovascular diseases, and prostate cancer treatment, while 10 percent are due to psychological causes . In many cases, however, both psychological and physical factors contribute to the condition.

Where physical factor play an important role PDE-5( Phosphodiaterase) inhibitors have a significant role to play. These include drugs like Sildenafil (Viagra) and Vardenafil(Levitra). But none are as good as Tadalafil(Cialis). Why?

Firstly let’s understand how PDE-5 inhibitors work. They work by inhibiting the enzyme phosphodiasterase-5 which is responsible for degrading another enzyme called cGMP(cyclic Guanosine Mono Phosphate) which through a series of reactions is responsible for the synthesis of nitric oxide. Nitric oxide is an important vasodilator responsible for dilation of the blood vessels that supply blood to the penis. Thus, there is an increase in the blood supplied to the penis and this increased blood engorges the penis and leads the formation of an erection through hydraulic pressure.

Therefore their action lasts for only 4 hours, while Tadalafil(Cialis) is absorbed and eliminated slowly therefore it remains in the body for a longer period of time. Therefore its duration of action is 9 times that of other drugs – 36 hours. This ensures that Cialis will act over a whopping 36 hours and any patient on Cialis does not need to have hurried sex , but sex at his or his partner’s leisurely pace. That is why Cialis has been nicknamed as “Le Weekend Pill” in France. It allows the man to relax with his partner and have spontaneous sex.

Also other drugs like Viagra act on the enzyme PDE-6, which is found in the eyes, leading to bluish discolouration of vision, which will not occur with Cialis.

Cialis can be taken with a 100% fat meal and there will be no change in it’s action. The same is not true for Sildenafil or Vardenafil, which are affected by food.

All this makes Cialis currently the best drug for erectile dyfunction.
