Organic or physical causes for sexual dysfunction in men include vascular, hormonal and neurologic buy generic viagra online no prescription 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 testosterone level. One investigator in Italy gave testosterone to patients with low testosterone who did not respond to sildenafil (Viagra). When daily testosterone was given, subsequent sildenafil (Viagra) use resulted in IIEF (the International Index of Erectile Function questionnaire used to determine erectile function) scores improving significantly. Other risk factors for erectile dysfunction include neurologic problems (multiple sclerosis, stroke), depression and medications for treating diabetes, hypertension, heart disease and depression.

There are many oral therapies for erectile dysfunction, but the only approved medication in the US is the PDE 5 enzyme inhibitor sildenafil (Viagra). Unapproved therapies, some of which are available in the US and some elsewhere, some of which have data to prove efficacy and some not, include tadalafil (Cialis), vardenafil (Levitra), yohimbine, phentolamine, trazodone, apomorphine and neutraceuticals. PDE5 inhibitors act to relax penile erectile tissues with sexual stimulation thus enhancing your ability to get an erection. 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) is similar to sildenafil, while tadalafil (Cialis) is very different. 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) has a half-life of 4 hours and vardenafil (Levitra) has a half-life 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 buy generic viagra online no prescription and not relate the sexual activity to the immediate use of the medication. The drawback is if you need nitrates after using tadalafil (Cialis), this medication lasts a long time in your blood stream and may place you at a higher risk.

Younger people might do well treated with tadalafil, (Cialis) while older people with other health issues might be better off using sildenafil (Viagra) or vardenafil (Levitra) but more data are needed.

The side effects of vardenafil (Levitra) are potentially less than sildenafil (Viagra), but more data are needed.

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

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.

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 order cialis online reddit 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 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.
