The Efficacy and Safety of Flexible-Dose Vardenafil (Levitra®) in a Broad Population of European Men

Louis Liou, chief of urology at Harvard-affiliated Cambridge Health Alliance in Boston. "For new patients, I have them try different ones to see what works best." Sildenafil (Viagra) is often the first drug your doctor offers. It's been on the market longest and its side effects and the medications and foods it interacts with are well known. But the main challenge to finding the best ED drug for you may turn out to be health insurance rules—not biochemistry. It's a common practice among insurers to limit the number of pills you can obtain per month.

You can take it half an hour before you hope to see its effects, and you will retain its power for as long as 36 hours. It’s this that gives Tadalafil the nickname, ‘the weekend pill’ – because having taken the pill, you are ready to go all weekend. When it comes to their ability to tackle erectile dysfunction, Cialis and Levitra largely emerge as similar in their effectiveness. Whilst the length of time for which they are effective differ, they should both be successful in their treatment of ED. However, if one of the drugs has the edge, it would be Tadalafil.

How to Use Viagra™

According to a meta-analysis of 118 different trials – involving over 30,000 patients – Tadalafil was found to be the most effective PDE5 inhibitor overall. In a slightly smaller study, which tracked users of Tadalafil, Vardenafil, and Sildenafil over six months, Tadalafil again emerged as the drug with the “higher levels of therapeutic effectiveness and satisfaction.” In a number of further studies comparing Sildenafil, Tadalafil, and Vardenafil, patients generally demonstrated a preference for Tadalafil overall. However, different drugs have different levels of efficacy for different people. In this respect, even though Vardenafil appears to be slightly less effective, it may well work for you. The side effects of Vardenafil and Tadalafil are those commonly seen in other PDE5 inhibitors.

Cost and Accessibility

Generally, PDE5 inhibitors lower your blood pressure – and, in the majority of cases, the side effects are the result of precisely this. These can include headaches, flushing, congestion, and muscle pain – but it’s rare. However, there is also the chance of the notorious condition known as priapism, a prolonged and painful erection that will not subside. This is incredibly rare – and whilst the first known case of priapism from Tadalafil caused a stir, the side effect is probably equally uncommon with Levitra, too. Despite this, studies have suggested that Vardenafil is the PDE5 inhibitor with the highest rate of side effects, with at least one side effect occurring in 25% of cases. After you hit your limit, the out-of-pocket cost for a single pill can be very high. "The main obstacle in my practice is the cost," Dr. Liou says.

You'll need to work with your doctor to get the pill you need at a price you can afford. In addition to Viagra, other ED drugs available in the United States include avanafil (Stendra), tadalafil (Cialis) and vardenafil (Levitra). These all improve blood supply to the penis. In combination with sexual stimulation, the drugs can produce an erection sufficient to initiate and complete intercourse. There is also a fast-dissolving form of Levitra, called Staxyn, that you put under your tongue. One ED drug, Cialis, is FDA-approved for use daily in a dose of 2.5 or 5 milligrams. This helps to produce erections on demand and may also help relieve urinary problems, like difficulty starting urination, that result from an enlarged prostate.

2.1 Active Ingredient and Mechanism of Action

What are the differences between erectile dysfunction drugs? About half of men ages 40 to 70 have erectile dysfunction (ED) to some degree, although only one in 10 report a complete inability to have erections. Taking an ED drug produces an erection sufficient to start intercourse in about 70% of otherwise healthy men. Does it make any difference which of the four drugs for erectile dysfunction you take? "Yes, there can be differences," says Dr. The cost to you for ED drug therapy varies considerably, depending on the pharmacy price, prescription co-pays, and your level of health plan coverage. Even if private insurance covers it, you may be limited to four doses per month.

Cialis (Tadalafil)

• Yohimbine: Natural supplement derived from yohimbe bark, may help with erectile problems.
• Ginseng: Traditional herb believed to enhance libido and improve erectile function.
• L-arginine: Amino acid that boosts nitric oxide, promoting blood flow to the penis.
• DHEA Supplements: Hormone precursors that may improve sexual function in some men.
• Acupuncture: Alternative therapy that could potentially improve erectile issues by stimulating energy pathways.
• Papaverine: Used in injections, relaxes penile muscles as an ED treatment alternative.

ED drugs produce an erection sufficient for intercourse in about 70% of men. But the results vary quite a bit from one individual to another. A man with nerves or arteries damaged by prostate surgery, diabetes, or cardiovascular disease will not respond as strongly to ED drugs.

"There are some men in whom none of these drugs work," Dr. Liou says. How soon the drugs start working ranges from 15 to 60 minutes.

1. Background of Erectile Dysfunction and Need for Alternative Formulations

Similarly, according to official US medical advice, Levitra can cause dizziness, nausea, and flu-like symptoms, side effects that are not seen with Tadalafil. Tadalafil, however, has demonstrated slightly higher chances of experiencing back and muscle pain as side effects. This is believed to be the result of the longer time it takes for the drug to be broken down. Vardenafil also is much less likely to cause changes to the colour of your vision, a side effect more commonly associated with Sildenafil. Whilst it is not hugely comfortable to dwell on the side effects of drugs, it is important to know what to expect.

Side Effects:

Meanwhile, it is worth repeating: yes, both drugs are safe – and they have been licensed for medical use precisely because of this. Both Cialis and Levitra are safe, effective, and licensed for the treatment of erectile dysfunction. As a result, the treatment that you pick is ultimately down to you. In the end, it might be merely a question of practicalities. Would you prefer a longer-lasting effect, so that you are ready whenever you need it?

How It's Designed to Work

Or would taking the pill just when it’s required be more convenient? But remember, you are not obliged to stick to one option for life. If one drug doesn’t work for you, there is no problem in trying the alternative. Every man’s body is different – and the drugs will inevitably work a little differently from person to person. Whilst Tadalafil might have the edge in terms of effectiveness and the frequency of side effects, you may not want the drug in your system for 36 hours. Neither Viagra nor Levitra will work if you take them after a meal, which blocks their absorption. However, neither Cialis nor Stendra interact with food this way. The onset time determines how soon you can engage in intercourse.

Product / Method	Average Cost per Dose	Over-the-Counter / Prescription	Notes
Levitra (brand)	$20-$50	Prescription	Brand name, higher cost
Generic Sildenafil	$1-$5	Prescription	Most affordable generic option
Tadalafil (Cialis)	$15-$40	Prescription	Longer duration of effect
Herbal Supplements	$10-$30 for a month's supply	OTC	Variable quality, less regulated

Stendra and daily-use Cialis are closest to being an "on demand" erectile drug; using the others requires more planning. Dr. Liou says that some men come to him after getting a prescription from their primary care doctors, claiming that the drug doesn't work.

• Cialis (Tadalafil): Long-lasting ED treatment alternative, effective up to 36 hours, available by prescription.
• Stendra (Avanafil): Fast-acting ED medication, starts working in 15 minutes, fewer side effects.
• Avana (Avanafil generic): Cheaper generic option for fast-acting erectile dysfunction relief.
• Herbal Supplements: Natural options like ginseng and L-arginine may improve erectile function.
• Vacuum Erection Devices: Mechanical pumps increase blood flow to achieve an erection without medication.
• Penile Injections: Medications like alprostadil injected directly into the penis for effective results.
