VIAGRA ®

What Is VIAGRA ®?

VIAGRA ®, a product of Pfizer Pharmaceutical Company, is a pill used to help a man with erectile dysfunction (impotence). It can help many men who have erectile dysfunction get and keep an erection when they become sexually excited (stimulated). It does not "cure" the underlying problem, and a man will not get an erection simply by taking this medicine. VIAGRA ® is not a magic bullet! helps a man with erectile dysfunction get an erection only when he is sexually excited. This means, he first must feel some desire and he must then get sufficient and effective erotic stimulation.

How VIAGRA ® Works

In many men with erectile dysfunction, VIAGRA ® will help the body's natural erection process. When a man is sexually aroused, the spongy cylinders within the penis fill with enough blood to cause the penis to enlarge and become firmness. After having ejaculated, the blood rapidly drains, and the erection goes away. This softening of the penis typically becomes more rapid as the man ages.

Pfizer explains the process as follows: "Sildenafil citrate (Viagra) works on an enzymatic level. It suppresses the enzyme phosphodiesterase type 5 (PDE5), which naturally occurs in erectile tissue. Phosphodiesterase type 5 (PDE5) breaks down the body chemical known as cyclic GMP. Cyclic GMP is produced during arousal and causes muscular and vascular changes, which lead to an erection. Men who don't produce a sufficient amount of cyclic GMP will have problems achieving an erection. Likewise, men with high levels of the enzyme phosphodiesterase type 5 (PDE5) will have problems maintaining an erection."

VIAGRA ® Is Not for Everyone

Sildenafil citrate will not produce the same results in all men. This is the case because for cyclic GMP to do its job in the first place, there have to be specific receptors. Men who genetically have a large number of receptor sites for cyclic GMP are more likely to produce better erections than those with a smaller number. It's a variation in the human race that cannot be corrected by sildenafil citrate.

Many younger men believe that Viagra will turn them into super stars in the bedroom. However, sildenafil citrate has only little effect in many younger men who do not suffer from erectile dysfunction. This is because sildenafil citrate will only work when erectile dysfunction is caused by either an insufficient amount of cyclic GMP, or by an overly active enzyme phosphodiesterase type 5 (PDE5). Either condition is more likely to be present in older men than it is in younger men.

VIAGRA ® is only for patients with erectile dysfunction. VIAGRA ® is not for women. Research is being conducted, however, to evaluate the effectiveness of the medication for females with low sexual desire or a difficulty in becoming aroused. Until the results are known, we do not recommend the use of VIAGRA ® by women.

(HerTurn ® is one of several new topical cremes for women that does not contain sildenafil citrate. The cremes for women contain very different ingredients and involve a very different process. The world still waits good clinical evidence that the topical cremes for women are effrective.)

Some Warnings

Do not let anyone else take your VIAGRA ®.

VIAGRA ® must be used only under a doctor's supervision.

VIAGRA ® must never be used by men who are taking any medicines that contain nitrates. Nitrates are found in many prescription medicines that are used to treat angina (chest pain due to heart disease) such as:

nitroglycerin (sprays, ointments, skin patches or pastes, and tablets that are swallowed or dissolved in the mouth)
isosorbide mononitrate and isosorbide dinitrate (tablets that are swallowed, chewed, or dissolved in the mouth)

Nitrates are also found in illicit drugs such as amyl nitrate or nitrite ("poppers"). If you are not sure if any of your medicines contain nitrates, or if you do not understand what nitrates are, ask your doctor or pharmacist. If you take VIAGRA ® with any nitrate medicine or illicit drug containing nitrates, your blood pressure could suddenly drop to an unsafe level. This could lead to dizziness, fainting, or even have heart attack or stroke.

What VIAGRA ® Does Not Do

VIAGRA ® does not cure erectile dysfunction. It is a treatment for erectile dysfunction.

VIAGRA ® does not protect you or your partner from getting sexually transmitted diseases, including HIV-the virus that causes AIDS.

VIAGRA ® is not a hormone or an aphrodisiac. It will not cause you to have sexual desire.

What are the Possible Side Effects?

Like all medicines, VIAGRA ® can cause some side effects. These effects are usually mild and do not last long. Some of these side effects are more likely to occur with higher doses.

VIAGRA ® is generally well tolerated. Side effects are rare, but if experienced they are usually mild and temporary.

The following is a list of the most common side effects.

"During my practice as a sex therapist, I met many men who have found Viagra to be very well tolerated and of great benefit in obtaining and maintaining satisfactory erections. As a sex therapist, I have appreciated the fact that Viagra is not magic that works automatically. However, it does work wonderfully well in most cases where the partners are both interested, patient and sensual in their foreplay. With physical and psychological stimulation, men who have been diagnosed as having an erectile dysfunction do remarkably well!"

Internet Websites Selling Herbal Treatments for Erectile Dysfunction

By R. Thurairaja; B. Barrass; and R. Persad

In the International Journal of Impotence Ressearch. 2005; Vol. 17 (2): Pages 196-200. ©2005 Nature Publishing Group

Abstract

The objective of the study was to investigate the safety and reliability of internet websites selling and providing medical information regarding herbal substitutes for Viagra. Using keywords 'Herbal' and 'Viagra', websites selling and providing medical information regarding herbal substitutes were identified. The top 50 sequential sites were assessed for safety and reliability against the Health on the Net (HON) criteria. Medically trained staff provided information in only 21% of the sites yet just 24% stated that the information was not a replacement for medical advice. No sites warned patients about erectile dysfunction (ED)-associated cardiovascular disease. In all, 88 and 70% of sites indicated drug efficacy and ingredients but only 36 and 21% provided contraindications and side effects, respectively. All sites fell short of the HON requirements. In conclusion, acquiring medical information and herbal substitutes for ED from the internet is convenient and easy. However, patients should be cautious as safety and reliability of this approach is poor.
