Erectile dysfunction (ED) is one of the most commonly reported sexual problems in men. In this condition, men face a consistent inability to achieve or sustain an erection of the penis long enough to complete sexual intercourse. ED is commonly reported by men above 65 years of age, not because impotence is a natural part of the ageing process but because the elderly are more likely to suffer from conditions such as diabetes, high blood pressure and high cholesterol that may interfere in the natural process of erection. Sometimes, young men may also report erectile dysfunction, but this is mostly due to psychological factors such as depression, sexual boredom and performance anxiety. In most cases, impotence due to psychological reasons is effectively treated through counselling and sex therapy.
When the cause of ED is physiological in nature, the first line of treatment is the use of Viagra, Levitra and Cialis specifically designed drugs for erectile dysfunction. Only these 3 drugs are approved by the US FDA as a prescription only treatment for impotence. Viagra, Levitra and Cialis belong to the same class of medicines called phosphodiesterase type-5 (PDE5) inhibitors and therefore they work in the same way. In response to sexual stimulation, the active ingredients in these 3 drugs for erectile dysfunction which include sildenafil (Viagra), vardenafil (Levitra) and tadalafil (Cialis), dilate the smooth blood vessels in the penis so that more blood can rush in to the penis. As a result, the penis is filled with blood and you are able to achieve a firm erection. The erection is sustained by blocking the action of the enzyme called PDE5 which is responsible for the breakdown of your erection. Once sexual intercourse has been satisfactorily completed, the penis returns to its normal flaccid state.
While Viagra and Levitra are quite similar, Cialis tadalafil works a little differently as it becomes effective faster and remains effective for a very long time. While Viagra and Levitra become effective within 60 minutes, Cialis becomes effective within 30 minutes. In addition, both Viagra and Levitra remain effective for just 4 hours in your body, while Cialis remains effective for 36-hours. Cialis thus offers men greater opportunities for spontaneous lovemaking and is therefore the much preferred drug for erectile dysfunction treatment.
