Open Surveys
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.
What Does Levitra Do to the Blood Vessels?
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). 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 Phentolamine’s application to the FDA was withdrawn and the drug is not available.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. All three medications are contraindicated in patients who take nitrates.
- Erectile Dysfunction Pill Alternatives: Non-prescription options with natural ingredients.
- Herbal extracts like Saw Palmetto: Support prostate health, indirectly benefiting erectile function.
- L-citrulline: Amino acid that converts to nitric oxide, enhancing blood flow.
- Chewing Gums with Herbal Extracts: Some marketed as natural ED aids.
- Dietary Adjustments: Incorporating foods high in flavonoids to improve circulation.
- Regular Exercise: Boosts cardiovascular health and supports sexual function.
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.

Finally Cialis has a long period of activity and patients are successful at intercourse up to 36 hours after taking this pill. This represents a distinct advantage from the patient’s perspective as it diminishes the need for planning. Sex can be more spontaneous and natural. Having sex long after taking the pill makes men feel more normal! For these reasons I will first try Cialis on all my Patients and reserve Viagra and Levitra for those men who do not tolerate Cialis.
Phosphodiesterase Type 5 Inhibitors: The Day After
The steps illustrated in Reference #4 below will help optimize the chances of success of Levitra and Viagra4. Reliable safety data gathered in the 10 years since these PDE % inhibitors were launched confirm that side effects such as Priapism (prolonged erection), red eyes, painful eyes, syncope(fainting), tachycardia (rapid heart rate), and nausea do occur, but are rare. Back pain and muscle aches occur rarely with Cialis. HIV medications (protease inhibitors) have been shown to raise their blood levels. Certain patient groups are more susceptible to a decrease of their blood pressure, including those with aortic stenosis, hypertrophic obstructive cardiomyopathy, and multiple system atrophy.
Pharmacotherapy for erectile dysfunction
Finally, all PDE 5 inhibitors remain contraindicated in patients taking nitrates. A few new safety concerns such as visual and hearing loss have emerged in the past year, however these remain extremely rare reinforcing that these medications are very safe. Indeed, we now know that many patients with cardiovascular disease (CVD) and ED benefit from it. Dr. J. 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.

The Bottom Line
A high fat meal will delay the absorption of Viagra™, and therefore it is recommended that Viagra™ is taken on an empty stomach or after a lowfat meal. Furthermore, once absorbed, Viagra™ will stay in the circulation for approximately four to six hours, which represents the window of sexual opportunity. If initially not successful, patients should try Viagra™ at 100mg on 3 different occasions before concluding that the medication is ineffective. Viagra™ is effective in two-thirds of men with erectile dysfunction regardless of age and the severity of Erectile Dysfunction. However, certain groups of men using the drug do better than others.
How Levitra works:
For example, spinal cord injured males have better results than patients suffering from cardiovascular disease (e.g. hypertension, high serum fat levels), and patients who have undergone treatment for prostate cancer (e.g. removal of the prostate or radiation therapy) seem to benefit the least. Most side effects are mild and well-tolerated. The following are the most common reported side effects: headache, flushing of the face, heartburn, and nasal congestion.
What Are PDE5 Inhibitors?
A small percentage (3%) of people may develop visual disturbance; it may take the form of a blue haze or tinge as well as increased perception of brightness. This effect is very mild, transient, and reversible. Viagra™ is CONTRAINDICATED for patients levitra 100 mg who take any medications that contain nitrates. This includes patients who need nitrates (including nitroglycerine) on an intermittent basis for the treatment of angina. In patients used to regular exertion, sexual activity poses no special cardiovascular risk. 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.
Erectile Dysfunction: Oral Therapy Treatment Options
Tell your doctor if you take any other medications including prescription and non-prescription medicines, vitamins or any health supplements as Cialis and these may affect each other adversely. It is taken orally before sexual activity, not more than once daily. It may be taken with or without food. In some patients, the dose strength and maximum frequency of use may be adjusted.

Some patients (younger men) may experience benefits from the medication as early as 30 minutes after taking it. In conclusion, the potencies of Viagra, Levitra and Cialis are broadly similar, but each has unique pharmacological properties related to its molecular structure.
Advancing Effective Research Policy
Francois Eid discusses the oral therapy options, or “pills”, available to treat erectile dysfunction. The following can be prescribed a PDE 5 inhibitor (Cialis, Levitra, Viagra) safely without the need for extensive Cardiovascular investigation²: men who are a symptomatic and have fewer than three risk factors for coronary artery disease patients who have undergone successful coronary revascularisation (bypass or stent placement) men with a history of uncomplicated heart attack that happened greater than 6-8 weeks ago those with mild valvular disease of the heart patients with mild left ventricular disease and congestive heart failure (NYHA Class I) Oral medications such as Cialis, Levitra and Viagra are available for the treatment of erectile dysfunction. They are in a class called PDE 5 inhibitors. They work to restore a normal system of blood flow in the penis so that an erection can occur with sexual stimulation.

Levitra (Generic Vardenafil) Overview
Even in patients who have a history of myocardial infarction (MI), there is little risk of MI during intercourse for those who exercise regularly. However, there is insufficient information on the cardiovascular risk in previously sexually inactive men who become sexually active. Stress test and/or referral to a cardiologist may be appropriate, and variables such as patient’s age, medical history and existing medical conditions may be relevant. 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. Cialis and Levitra are the newer medications and are similar to Viagra in their efficacy and contraindications.
