How do these drugs work?

All three medications are contraindicated in patients who take nitrates. A recent survey looking at what patients with ED really want from their treatment found that efficacy and a favorable side-effect profile were the highest priorities³ Fast onset was desirable, but there were major differences in what was considered fast. Duration was important only in terms of lasting long enough to complete intercourse. Few men (or their partners) felt that multiple erections, or the ability to achieve them over time, were critical as long as one dose was enough for a successful encounter. Most complaints were about high cost or lack of insurance coverage.

An underlying desire was reported by most couples for initiation of sex to be normal (spontaneous and natural). Few patients fully understood the duration of activity that Viagra can provide, and its advantages. Cialis may indeed fulfill the desire that couples and patients with ED have for the initiation of sex to be normal (spontaneous and natural). Although Viagra, Levitra and Cialis are safe and effective they do, like all medications, have disadvantages. They essentially enhance partial (sexual) erections, rather than initiating them.

Levitra (Vardenafil) dosage forms

At best, the response rate among men with advanced ED (for example following radical prostatectomy) is 30%. Fewer than 505 of men with Diabetes will respond. Correct administration of Viagra and Levitra is critical, and if one does not work when taken correctly, no other oral “Viagra like drug” (PDE5 inhibitor like Levitra or Cialis) will either. In conclusion, the potencies of Viagra, Levitra and Cialis are broadly similar, but each has unique pharmacological properties related to its molecular structure. Viagra is an exemplary PDE-5 inhibitor that, after 10 years of widespread clinical use, is acknowledged to be effective and particularly well tolerated. Permanent damage to the penis may occur if priapism is not treated quickly. Stop taking vardenafil and get emergency help if you have any of the following symptoms of priapism.

Alternative oral therapies for Erectile Dysfunction (availability may vary geographically) are Uprima (apomorphine), and phentolamine. Both Uprima and phentolamine have very low or no efficacies and therefore for present purposes will not be addressed. Uprima is approved for the treatment of Erectile Dysfunction in Europe and initial sales have not been very impressive (less than 20% of ED market).

Is Levitra or Viagra better?

Refill rates are dismal supporting lack of efficacy. Phentolamine’s application to the FDA was withdrawn and the drug is not available. Although Viagra, Levitra and Cialis differ in their biochemical potency and selectivity, and in onset and duration of action, it is important not to extrapolate those findings inappropriately to the clinical setting. For example, greater biochemical potency does not necessarily translate into enhanced clinical efficacy. In short, there appears to be little biochemical or clinical differences between the three agents except for the lack of food interaction and the duration of activity for Cialis.

Cialis and Levitra are the newer medications and are similar to Viagra in their efficacy and contraindications. The only new attributes of clinical significance are the lack of food interaction and the long duration of action of Cialis. This may translate into greater efficacy of the first dose as well as a return to more spontaneous (normal) initiation of sexual activity (broader window of opportunity).
