Levitra is a medication that is popular among men who experience common sexual problems, such as erectile dysfunction (ED), which is defined as difficulty in achieving a healthy erection for a normal sexual intercourse, and premature ejaculation (PE), which is a shortened interval between penetration and ejaculation. Levitra contains the chemical substance known as Vardenafil, which is classified as a blocker of the phosphodiesterase type 5 enzyme found in the penis and in the pulmonary blood vessels (PDE5 inhibitor). This class of drugs also incorporates well-known erectile dysfunction remedies like Sildenafil (Viagra) or Tadalafil (Cialis).
All drugs in this group work in a similar way in terms of their physiologic effects and ability to facilitate a healthy erection, but they may be slightly different in terms of their time of efficient action and other biochemical parameters such as distribution, blood concentration or elimination. Levitra (Vardenafil) is a safe drug belonging to PDE5 inhibitors because it has passed of the necessary clinical trials, and its effects have been thoroughly evaluated by pharmaceutical experts. Levitra may also be recommended by pharmacists and doctors for other ailments besides erectile dysfunction or premature ejaculation, such as pulmonary hypertension and even sexual disorders that involve sexual arousal abnormalities in women through an increased pelvic blood circulation.
How does Levitra (Vardenafil) influence the male physiology to achieve a strong support and facilitation of a healthy erection prior to sexual intercourse in men afflicted by ED? The physiologic and biochemical events that results in a healthy erection start with sexual arousal, which stimulates certain brain areas to respond through the transmission of a nervous signal to nerve fibers distributed throughout the penis. These nervous fibers “communicate” with the blood vessels in the penis through a special chemical messenger – nitric oxide (NO). This chemical released from the nerve endings is interacting with an enzyme, leading to its activation and an enhanced production of cyclic GMP. This chemical (cGMP) is the compound that directly widens the blood vessels in the penis, which are found in a modified form known as the cavernous structures. These blood vessels are able to facilitate huge amounts of blood to enter the penis, which is how an erection essentially takes place.
This is where the PDE5 enzyme comes into play, and its activation leads to the destruction of cyclic GMP, which diminishes the erection through the inhibition of blood vessel dilation in the penis. This mechanism may lead to problems with the erection, which are further amplified by psychological problems like a low self-confidence that need to be addressed through gradual psychotherapy. Levitra is able to block the PDE5 enzyme and facilitate the beneficial effects of cyclic GMP on the blood vessels. Make sure to talk with a medical professional before using Levitra, and inform your physician about any unwanted effects that may occur during the treatment. Most side effects are usually rare and disappear quickly upon dosage correction.
