The most common sexual dysfunctions in men include lack of interest, premature ejaculation and erectile dysfunction.

The latter affects 52% of men between the ages of 40 and 70, including mild, moderate and complete forms of ED.

Organic or physical causes for sexual dysfunction in men include vascular, hormonal and neurologic factors.

Concerning vascular causes, the risk factors for atherosclerosis (including smoking, high blood pressure, diabetes (diabetics do not respond well to pills like sildenafil (Viagra)) and high cholesterol are ALSO risk factors for erectile dysfunction.

Since a straddle injury or use of a narrow saddle can obstruct and impair arteries to the penis, bicycle riding is also considered a risk factor for erectile dysfunction.

Little attention has been paid to endocrine factors. Testosterone modulates desire, arousal and orgasmic function.

Concerning the orgasmic response, testosterone modulates the integrity of genital sensory receptors.

Concerning the arousal response, decreased testosterone blood levels can influence the efficacy of sildenafil (Viagra). If the sildenafil response is not reliably improving erection, the physician should first check if the patient is taking the pill correctly. The physician should also check the

patient’s

Sildenafil (Viagra) is effective for all sorts of erectile dysfunction in 69% of people. In some cases the erection is not hard enough, sometimes sildenafil (Viagra) just doesn’t work.

Structurally vardenafil (

Levitra

Vardenafil (Levitra) is almost 10 times more biochemically potent than sildenafil, therefore a lower dose is needed to facilitate the penile erection, potentially resulting in less side effects. Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues. Vardenafil (Levitra) is more selective than sildenafil and tadalafil (Cialis) to PDE5, which again means a lower dose is needed with potentially less side effects. Tadalafil is very specific for PDE5 and is also very specific for the enzyme PDE11. Unfortunately, we don’t know much about PDE11, which is found in the heart, in the pituitary gland in the brain and in the testicles.

Pharmacokinetics, half-life, is how long the medication stay s in the blood. Sildenafil viagra super active coupon (Viagra) has a half-life of 4 hours and vardenafil (Levitra) has a half-life buy viagra generics of 4-6 hours while tadalafil (Cialis) has a half-life of 17.5 hours. This means that vardenafil (Levitra) should act longer than sildenafil (Viagra) but the clinical significance is not known.

Tadalafil (Cialis) has the longest half-life and allows you to take the medication and not relate the sexual activity to the immediate use of the medication. The drawback is if you need

nitrates

In a recent study on men with erectile dysfunction and diabetes, vardenafil (Levitra) improved their erectile dysfunction.

Tadalafil (Cialis) is as effective as sildenafil (Viagra), and vardenafil (Levitra) with similar side effects except for back pain that occurs occasionally with tadalafil, probably because of the long half-life.

Many people stop taking drugs because they are experiencing side effects, they no longer have a partner, or they are worried about safety. Sexual activity is not a major contributor to the risk of a heart attack. Sexual activity, with or without sildenafil (Viagra) increases the chance of an MI during sexual activity by only 0.1%. If pills fail, there are vacuum devices, Muse, injections, bypass surgery and implants.

The patient making a presentation has had penile bypass surgery. In addition he takes testosterone and sildenafil as needed..

This is a classic example of why people with ED need complete care: a psychological exam, history and physical exam, and diagnostic studies with long term follow-up care. Patients with ED should not just be prescribed sildenafil (Viagra) and then be lost to follow-up.

Vardenafil, also known by the brand name Levitra, is a prescription medication that treats male erectile dysfunction.

Erectile dysfunction is when a man is unable to get or sustain an erection.

It usually

happens

Its action is similar to that of sildenafil, or Viagra, but Viagra lasts between 2 and 4 hours, while Levitra lasts 4 hours. Share on Pinterest Vardenafil can help a man get and maintain an erection. During a penile erection, the penis fills with blood.

The blood vessels that supply the penis with blood expand, or dilate, and the vessels that take blood away from the penis contract.

The two large chambers in the penis, known as the corpus cavernosa, fill with blood.

As the blood accumulates in the penis, an erection results.

Vardenafil belongs to a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors. A PDE5 inhibitor stops PDE5 from constricting the arteries. By relaxing the arteries, vardenafil enhances blood flow when a man is sexually aroused.

The active ingredient works on the chain of reactions within the penis during arousal. When a male is sexually aroused, nitric oxide is released into his penis, and this triggers a chain of reactions. This causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP).

cGMP regulates the contraction and dilation, or expansion, of blood vessels that carry blood to and from the penis. The chemical reaction causes the vessels that supply viagra cheap generic the penis to dilate, while those removing blood from the penis contract.

Phosphodiesterase-5 (PDE5), another enzyme breaks down or destroys cGMP. When cGMP is destroyed, the blood vessels return to their normal size, effectively ending the erection. Viagra, Cialis, Levitra, and Stendra: Which is best? Viagra, Cialis, Levitra, and Stendra are popular drugs for treating the symptoms of erectile dysfunction. They all have approval from the United States Food and Drug Administration (FDA), and they have the same function, but there are some differences between them. It is important to understand these differences in order to make the best choice about which to choose. Share on Pinterest Cialis and Viagra are PDE5 inhibitors that help to relax the muscles and increase blood flow.

Viagra is the brand name for the drug sildenafil, Cialis is the brand name for tadalafil, Levitra is the brand name for vardenafil, and Stendra is the brand name for avanafil.

This means they help to relax the muscles and increase blood flow to the body. This makes it easier for blood to get into the penis, and it allows people with erectile dysfunction (ED) to experience a lasting erection during sexual activity.

Manufacturers of PDE5 inhibitors recommend taking the pill at least 30 minutes to 1 hour before sexual stimulation, but the timing depends on the drug. How long the effect of each drug lasts is one of the key differences between them: Viagra is a drug that people use only when they need it.

A person takes the drug 30 minutes to 1 hour before sexual activity, and the effects typically last for 3-5 hours. Levitra may start working faster than Viagra, but it lasts for about the same amount of time. The effect of a similar dose of Cialis may last up to 36 hours. For this reason, people looking for a long-lasting drug may choose Cialis. Depending on the dose, Stendra will be effective after 15–30 minutes, and research shows it is effective for up to 6 hours. Viagra, Cialis, Levitra, and Stendra all come from the same class of chemicals, and they have many similar side effects and interactions. For instance, manufacturers recommend not taking PDE5 inhibitors with grapefruit or grapefruit juice, because the fruit may affect how the drugs work. Nitrates will also interact with these drugs, so people should not use them together. There are some drug-specific side effects to be generic viagra with dapoxetine aware of, however. The side effects include: headaches stomach buy viagra generics pain facial flushing congestion nausea or diarrhea color blindness blurred flibanserin buy online vision.

Interactions with Viagra do occur, and it is important for people to be aware of them before choosing a medication for ED.

Any drugs for pulmonary hypertension may also interact with Viagra, causing blood pressure to drop to unsafe levels.

A recent study in JAMA Internal Medicine has suggested that Viagra could increase the risk of skin cancer. The study found that 3.7 percent of skin cancer cases in men who used the drug sildenafil might have been prevented by not taking it. The side effects include: headaches facial flushing low blood pressure congestion dizziness chest pain.

People should not use it with guanylate cyclase stimulators or blood pressure medications, as this combination can trigger an unsafe dip in blood pressure.

A person who is taking Cialis and has prostate problems should avoid prescription alpha-blockers, as Cialis serves the same function. People should also avoid certain antifungal medications and antibiotics when taking Cialis. Anybody who is considering taking medications such as Cialis for ED should always involve their doctor in the

decision

The doctor may ask if the person has a history of any of the following: heart problems

stroke

All of these conditions may affect the doctor’s decision to prescribe Cialis. The side effects of Levitra include: headache congestion facial flushing indigestion upset stomach dizziness back pain color blindness. If a doctor has told a person to avoid sexual activity due to health problems, they should avoid Levitra.

Sexual activity can put extra strain on the heart, especially if it is already weak from heart disease.

As with Cialis, a person should not use Levitra with: buy viagra generics guanylate cyclase stimulators or blood pressure medications, as these can cause an unsafe dip in blood pressure that can lead to fainting alpha-blockers for prostate problems certain antifungal medications and antibiotics.

A doctor may ask a person if they have a history of any of the following: heart problems stroke hearing problems retinitis pigmentosa, an inherited eye condition liver or kidney problems stomach ulcers abnormal penis shape blood cell problems, such as sickle cell anemia. All of these conditions may affect a doctor’s decision to prescribe Levitra. People who are taking drugs to treat an abnormal heartbeat should also avoid taking Levitra. The manufacturers of Stendra claim that it has a low rate of side effects. However, like the other treatments for ED, there is a risk of adverse effects, including: a headache flushing a stuffy or runny nose a sore throat back pain vision problems, including possible sudden vision loss in one or both eyes hearing problems, including a decrease or loss of hearing and tinnitus low blood pressure priapism, an erection that will not go away. A buy viagra generics person should seek medical treatment if they experience: vision or hearing loss an

erection

People should not use Stendra if they have or have had: heart problems or heart surgery pulmonary hypertension low or high blood pressure a deformed penis a stroke severe vision loss bleeding problems a stomach ulcer kidney or liver problems.

Anyone with any kind of health condition should speak to a doctor before taking Stendra or any of these medications.

A person should not take Stendra with the following drugs: any type of nitrate guanylate cyclase stimulators, such as riociguat (Adempas) HIV protease inhibitors, such as ritonavir (Norvir) some antifungal medication, such as ketoconazole (Nizoral) some antibiotics such as clarithromycin (Biaxin) alpha-blockers and other medications for blood pressure other treatments for ED. People can take Stendra with or without food and with up to three servings of alcohol. It is important not to drink more than three alcoholic drinks, for example, three glasses of wine or three measures of whiskey, as this can lead to adverse effects. All four medications may sometimes cause priapism, an erection that will not go away.

If a person experiences an erection lasts for more than 4 hours, they should seek medical attention to avoid lasting damage.

In rare cases, these drugs can cause serious side effects, including sudden loss of vision in one or both eyes or sudden hearing loss. If a person experiences these symptoms, they should stop taking the drug immediately and call their doctor.

I am often asked which is the best of the three most common erectile dysfunction treatments: Viagra, Levitra or Cialis. There is no simple answer to this question, as some men find one treatment works better for them than the others. However there are some interesting differences… What is Viagra?

Viagra is the most well-known of the three as it has been around for over 15 years. This means that a lot is known about its effects and side effects. It works within an hour of taking a tablet, and is best taken on an empty stomach.

The effects of Viagra will last for four to six hours.

Viagra was developed and originally marketed by the pharmaceutical company Pfizer, and until 2013 Pfizer was the only company allowed to sell it.

When Pfizer’s patent on Viagra expired, the market was open for other companies to produce the medicine, albeit under its generic name Sildenafil, rather than the brand name Viagra. Sildenafil contains exactly the same active ingredient as Viagra (sildenafil citrate), and works in the same way. However, because it is the generic version of the medicine, rather than the brand, Sildenafil is considerably cheaper.

Levitra will last for a similar amount of time as Viagra (four to six hours).

The main difference to Viagra is that Levitra tends to be less affected by food or alcohol so can be taken with meals. There is also some evidence that Levitra is more effective in diabetics than other erectile dysfunction medicines.

The effects of Cialis (tadalafil) last much longer than those for Viagra or Levitra (up to 36 hours) so many men prefer it as involves less planning.

The downside is that if you do experience side effects these can last for longer too. Like Levitra, Cialis is not affected much by food, so can be taken after a meal. Different erectile dysfunction medicines suit different people, but it is difficult to tell which one will be best for you until you have tried them all.
