The active ingredient in Levitra is called Vardenafil, it belongs to the same class of medicines as Viagra and Cialis called phosphodiesterase type 5 (PDE-5) inhibitors and hence, all the three medicines essentially work in the same way. The action of Levitra causes the smooth muscle in the penis to relax allowing more blood to rush into the genital organ. As a PDE-5 inhibitor, Levitra (Vardenafil) prevents the action of the PDE-5 enzyme which is responsible for the breakdown of cGMP. This results in an improved blood flow to the penis helping a man to maintain an erection. Levitra does not cause an erection on its own; sexual stimulation is required to help men achieve an erection.
Levitra acts faster and remains effective for a longer period of time as compared to Viagra. While Viagra becomes effective in 60 minutes and remains effective for up to 4 hours, Levitra acts within 30-60 minutes and remains effective for up to 5 hours. Besides, Levitra needs to be taken in lower dosage strengths of 2.5mg, 5mg, 10mg and 20mg whereas Viagra is available in the dosage strengths of 25mg, 50mg and 100mg. Hence, the chances of experiencing side effects are much lower with Levitra as compared to Viagra.
Another reason why many men, suffering from impotence, prefer to take Levitra is that this drug has been shown to be effective and is well-tolerated in a broad range of men including those men who suffer from high blood pressure, diabetes, spinal cord injury, depression and in those who have had their prostate gland removed. Levitra is also reported to have a high first time success rate. A study showed that 74% of impotence patients achieve full sexual intercourse with their first Levitra tablet. According to recent researches, first dose efficacy is the most important treatment attribute, alongside speed of action for men suffering from impotence. This assures men that their condition is treatable and helps them regain confidence.
What is impotence?
Impotence is a common sexual problem that affects a large number of men across the world. Men suffering from impotence face a consistent inability to achieve or maintain an erection long enough to complete sexual intercourse. Though all men face performance failure at some point in their lives, if the problem occurs on a consistent basis it severely affects their quality of life. Men usually associate their sexual prowess with their virility; therefore, not being able to perform is a serious blow to their manliness and hence, they suffer from low self-esteem. Impotence also affects a man's relationship with his partner and sometimes relationships may come to an end because of the absence of sex. Erection problems are common in elderly men above 65 years of age; this is because they are more likely to suffer from conditions such as diabetes and high blood pressure that may interfere with the complex process of erection. Thanks to the availability of drugs like Levitra, men with impotence can now enjoy sex by just taking a pill when the need arises.
