Warnings & Precautions

Cialis is a commonly prescribed medication for ED. Like vardenafil and Viagra, Cialis takes about 60 minutes to work and must be used in combination with sexual stimulation. There are two ways to take Cialis. The first way is similar to vardenafil or Viagra, which is to take it about an hour before sexual activity. Cialis can also be taken at a low dose once a day regularly, without regard to sexual activity.

Side Effects:

Then, sexual activity can occur at any time in combination with stimulation. Vardenafil, sold under the brand name levitra 10mg tablets Levitra among others, is a medication that is used for treating erectile dysfunction. Vardenafil's indications and contraindications are the same as with other PDE5 inhibitors; it is closely related in function to sildenafil citrate (Viagra) and tadalafil (Cialis). The difference between the vardenafil molecule and sildenafil citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both sildenafil and vardenafil. Erectile dysfunction, often referred to as ED or impotence, is a common condition marked by a man’s difficulty or total inability to achieve an erection firm enough to perform sexual activities with his partner. ED is quite common in the male population, so numerous erectile dysfunction treatments are available to men in the Plano, Frisco and Dallas, Texas area. Dr. Mark Allen, urology specialist, offers a number of treatment options, including erectile dysfunction medications such as Viagra, Levitra and Cialis.

Trial summary

One possibly serious, but rare, side effect with vardenafil is heart attack. Also, in rare cases, vardenafil use may cause priapism, a very painful emergency condition that can cause impotence if left untreated. In October 2007, the U.S. Food and Drug Administration (FDA) announced that a warning about possible deafness (sudden hearing loss) would be added to the drug labels of vardenafil, and other PDE5 inhibitors. Vardenafil should not be used by people taking nitrate medications, because combining them with vardenafil might provoke potentially life-threatening hypotension (low blood pressure). Erectile dysfunction is defined as the persistent inability to achieve or maintain penile erection sufficient for satisfactory sexual performance.

How Do Vardenafil and Viagra Compare?

Like vardenafil, Viagra can also be taken with or without food. However, taking Viagra with a high-fat meal can make the medication take about an hour longer to work. In addition to vardenafil and Viagra, other PDE5 inhibitors include Stendra (avanafil) and Cialis (tadalafil). Some PDE5 inhibitors also treat different conditions. For example, Revatio contains sildenafil, like Viagra, but is used for pulmonary arterial hypertension (high blood pressure in the lungs).

How Levitra works:

Healthcare providers may also prescribe Cialis in lower doses for benign prostatic hyperplasia (BPH). Few studies directly compare vardenafil and sildenafil. An older study of these drugs, plus tadalafil, found vardenafil to be more potent than sildenafil, though both effectively treated ED. Tadalafil (Cialis) was preferred for its longer-lasting effects but was similarly effective. Another study found vardenafil to be better tolerated than sildenafil. ED is not just a medical issue – it can deeply affect relationships and limit intimacy, as well as affect a patient’s self-esteem.

In many cases, the first course of erectile dysfunction treatment is to prescribe an oral medication.

Further, vardenafil causes lengthening of the QT interval. Therefore, it should not be taken by people taking other medications that affect the QT interval (such as amiodarone).

As of 2005, the co-promotion rights of GSK on Levitra have been returned to Bayer in many markets outside the US.

Erectile Dysfunction Medications Overview

Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's. Despite the structural differences between vardenafil and sildenafil, they both show similar ocular side effects due to their similar selectivity overlap with PDE6, an enzyme found in the eye. Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from penetration to ejaculation. The common, adverse drug reactions (side effects) are the same as with other PDE5 inhibitors. The frequent vardenafil-specific side-effect is nausea; the infrequent side effects are abdominal pain, back pain, photosensitivity, abnormal vision, eye pain, facial edema, hypotension, palpitation, tachycardia, arthralgia, myalgia, rash, itch, and priapism. All of them work to create an erection when sexually stimulated, but they do not increase the actual sex drive of a man.
