Men’s health has never had it so good. Firstly men have drugs to treat impotence or to be more specific erectile dysfunction. Secondly these drugs not only treat erectile dysfunction(ED) but also may protect the heart and treat depression also. Erectile dysfunction is defined as the inability to ensure or sustain an erection for satisfactory sexual intercourse. It occurs in 150 million men all over the world. Most men (95%) do not seek treatment for this disorder. But times are changing. The increasing media profile on this condition has made men more aware and willing to at least consult their doctors for this condition. These doctors are prescribing the latest blockbuster drugs like Viagra, Cialis, but most importantly Levitra to treat men with Erectile Dysfunction.
All of these drugs belong to a class known as PDE-5 inhibitors. They block the enzyme Phosphodiasterase-5 and thus prevent it’s action (degradation) on another enzyme called as cGMP(cyclic guanosine monophosphate) which carries out a series of chemical reactions to produce nitric oxide, a known vasodilator. The higher the levels of nitric oxide, the greater the vasodilatation of the blood vessels. Therefore more blood flows into the penis and thus the penis swells up and we have an erection due to hydraulic pressure. Viagra contains the drug Sildenafil; Cialis contains the drug Tadalafil, while Levitra contains the more potent Vardenafil.
Are all these drugs equally potent? No. The most potent in terms of ensuring a strong hard erection is Levitra. In fact Levitra is 3 times more likely to work than Viagra, especially in difficult patient groups like diabetic men and men who have failed to treat erectile dysfunction with Viagra. Do all these drugs act quickly, Viagra takes about at least half an hour to act, while Cialis takes an hour. It is Levitra which will act in 16 minutes flat. However Levitra does not last as long as Cialis, which can show it’s effects for up to 36 hours. This property has earned it the name -Le Weekend Pill- in France. But most men do not have sex more than once in a 36 hour period. A time period of 4 hours is sufficient to have sex as with Levitra professional online.
Viagra must be taken on an empty stomach if it has to show it’s complete effects This is because Viagra’s action is diminished if it is taken with food. Both Cialis and Levitra can be taken with food.
