The following information is a summary about Viagra. It is not intended to replace a doctors instructions:
1.About erectile dysfunction
Erectile dysfunction (ED), also known as impotence, is the inability to have a hard erection initially and/or to have a hard erection that lasts long enough for sexual activity. Symptoms of erectile dysfunction include lack of an erection hard enough for penetration and/or lasting long enough for completion of sexual activity. ED may occur with or without other sexual dysfunction, including decreased libido (decreased interest in sexual activity), orgasmic dysfunction (troubles achieving an orgasm/climax), and ejaculatory dysfunction (problems with the fluid released during sex, including lack of ejaculation, small volume ejaculate, and pain with ejaculation). Erectile dysfunction is common, and the risk of developing ED increases with age. Experts have estimated that erectile dysfunction affects 30 million men in the United States. Treatments include psychotherapy, adopting a healthy lifestyle, oral PDE5 inhibitors (Viagra, Levitra, Cialis, Stendra, and Staxyn), intraurethral prostaglandin E1 (MUSE), intracavernosal injections (prostaglandin E1 [Caverject, Edex], Bimix and Trimix), vacuum is ongoing in the field of erectile dysfunction to find improved and effective therapies.
Viagra is a pill used to treat erectile dysfunction (impotence) in men. It can help many men who have erectile dysfunction get and keep an erection when they become sexually excited (stimulated). You will not get an erection just by taking this medicine. Viagra is taken approximately one-hour before sex. It is effective for about 4 hours. Sexual stimulation is still required to get an erection, but often times, less than would be normally required. It is recommended that it not be used more than once a day. The most common side-effects noticed were mild headache, facial flushing, and/or upset stomach. With larger doses, some men developed a very unusual side-effect: a color shift towards blue, making green and blue indistinguishable. Because Viagra does not cause an erection but simply makes it easier to get one, the most dangerous side effect of injectables (which do cause an erection) is avoided. Injections can cause a condition known as priapism where a man cannot lose his erection. This is a very dangerous condition that must be treated immediately, and can lead to permanent damage. Given that no chemical is being injected, Viagra also does not lead to scarring.
One point that needs to be emphasized is that difficulties with getting an erection occur to almost all men, at least some of the time. However, Viagra is designed for the approximately 140 million men worldwide affected by long-term erectile dysfunction. In studies, the drug was effective across patients with erection problems attributed to diabetes, prostatectomy, spinal cord injury, psychological, and other causes. It is not meant to be used casually and men should be carefully evaluated for underlying medical/psychological causes. Indeed, it is my concern that this drug will be given to men who really need relationship or personal counseling. Thus, many men will not get the help they really need. Difficulties with erections are often merely a symptom of underlying problems. If doctors merely hand out a pill, they will be doing men and their partners a great disservice.
The other interesting thing about Viagra (that no one is mentioning for fear that the drug will be abused), is that in many men, the drug allows them to maintain an erection even following multiple orgasms. So, in a sense, Viagra may eventually be useful for treatment of premature ejaculation. As a matter of fact, if this really works, it will be premature ejaculators who win out -- they still maintain their erection, but get to have more orgasms! Another implication is that for men who have partial erections, or easily lose their erections, this drug may make it easier for them to use condoms and have safer sex. Given the incredible risks some men take in not using a condom, this would seem to me to be a legitimate use for the drug.
3.How Viagra Works
Viagra enables many men with ED to respond to sexual stimulation. When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the penis. As the arteries in the penis expand and harden, the veins that normally carry blood away from the penis become compressed, restricting the blood flow out of the penis. With more blood flowing in and less flowing out, the penis enlarges, resulting in an erection.
Viagra , also known as Sildenafil, does not directly give a man an erection. It works by boosting the natural mechanism that leads to an erection. When a man is sexually aroused, certain tissues in his penis relax. This allows large amounts of blood to flow into the muscle, thus producing an erection. Viagra helps by elevating the levels of the chemical that causes the tissues to relax. These effects were discovered accidentally. The drug was originally developed to improve blood supply to the heart in angina sufferers.

Stop Erectile Dysfunction
1.Stop Erectile Dysfunction. Levitra.
In early 2003, a second prescription drug to treat erectile dysfunction, Levitra, was approved by the FDA. Like Viagra, Levitra helps increase blood flow to the penis and may help men with ED get and keep an erection. Once a man has completed sexual activity, blood flow to the penis should decrease and the erection should go away. Levitra should be taken approximately 60 minutes prior to sexual activity. In clinical trials, most patients were able to begin sexual activity before that time. A 2004 study showed that about 50% of men taking Levitra experienced a firm erection within 25 minutes and a small percentage in as quickly as 10 minutes. Studies also showed that Levitra improved erectile function in men who had other health factors, such as diabetes or prostate surgery. Men taking nitrate drugs, often used to control chest pain (also known as angina), should not take Levitra. Men who use alpha-blockers, sometimes prescribed for high blood pressure or prostate problems, also should not take Levitra. Such combinations could cause blood pressure to drop to an unsafe level. Levitra is available in 2.5 mg, 5 mg, 10 mg, and 20 mg tablets and should be taken no more than once a day. The average cost per pill is about $10 and is covered by many insurance plans.
2.Stop Erectile Dysfunction. Zenegra.
Sildenafil citrate was originally developed in 1991 as a treatment for angina, or chest pain. The drug, marketed under the name zenegra, received FDA approval as a treatment for erectile dysfunction in March 1998, and since that time it has been prescribed for more then 20 million men worldwide. It was the first oral medication approved for ED treatment. Zenegra is a vasodilator, a drug that has the effect of dilating the blood vessels. It works by improving blood circulation to the penis, and by enhancing the effects of nitric oxide, the agent that relaxes the smooth muscle of the penis and regulates blood vessels during sexual stimulation, allowing the penis to become engorged and achieve an erection. The average recommended dose of zenegra is 50 mg. It comes in doses of 25 mg., 50 mg., and 100 mg to. The medication is taken approximately one hour before sexual activity is planned, and may remain effective for up to four hours. One drawback is that to be effective, it should be taken on an empty stomach. Also, high-fat foods can interfere with the absorption of zenegra. Zenegra does not increase sexual desire. Sexual stimulation and arousal are required for it to be effective. Many insurance plans cover the cost of zenegra, provided it is prescribed to treat erectile dysfunction. The pills cost approximately $10 each, and insurers may limit coverage to a specific number of pills each month. The primary drawback to zenegra, which works about an hour after it is taken, it that the FDA cautions men with heart disease or low blood pressure to be thoroughly examined by a physician before obtaining a prescription. At least 130 men have died while taking zenegra. However, the FDA said the men—most over the age of 64—died of heart attack or stroke due to health problems exaggerated by sexual activity, not the drug itself.
3.Stop Erectile Dysfunction. Cialis.
Cialis is the third oral drug prescriberectile dysfunction to treat erectile dysfunction, approverectile dysfunction by the FDA in November 2003. Its most notable difference from Viagra and Levitra, which work for about four hours, is that Cialis works for up to 36 hours. Cialis helps increase blood flow in the penis when a man is sexually stimulaterectile dysfunction. It can help men with erectile dysfunction get and keep an erection satisfactory for sexual activity. Once a man has completerectile dysfunction sexual activity, blood flow to his penis decreases, and his erection goes away. Cialis is clinically proven to improve erectile function in most men with erectile dysfunction, including those with mild, moderate or severe erectile dysfunction. The most common side effects with Cialis are headache, upset stomach, back pain, and muscle aches. These side effects usually go away after a few hours. Patients who get back pain and muscle aches usually get it 12 to 24 hours after taking Cialis. Back pain and muscle aches usually go away by themselves within 48 hours. Cialis comes in 5 mg., 10 mg. (the recommenderectile dysfunction starting dose), and 20 mg. tablets. The average cost per tablet is about $10 and it is covererectile dysfunction by many insurance plans. Since the absorption of Cialis is not affecterectile dysfunction by food or high-fat foods, it does not neerectile dysfunction to be taken on an empty stomach. Studies show that in most men, Cialis begins working in about 30 minutes and may be taken up to once per day by most patients. Priapism, a prolongerectile dysfunction erection, is a very rare potential side effect of all prescription erectile dysfunction merectile dysfunctionications. Persons taking Viagra, Levitra, or Cialis who have a prolongerectile dysfunction erection, lasting more than four hours, should seek immerectile dysfunctioniate merectile dysfunctionical attention. Priapism can cause damage to the penis potentially leading to the permanent inability to have an erection. Because sexual activity can stress the heart, men who have heart problems should check with their physician to see if sexual activity is recommenderectile dysfunction. Erectile dysfunction drugs may trigger temporary hypotension (low blood pressure) and is known to increase cardiovascular nerve activity, so physicians should prescribe them with caution in men with a history of heart attack, atherosclerosis (hardening of the arteries), angina, arrhythmia, and chronic low blood pressure problems. erectile dysfunction drugs are not labelerectile dysfunction or approverectile dysfunction for use by women or children, or by men without erectile dysfunction. Anyone experiencing cardiovascular symptoms such as dizziness, chest or arm pain, and nausea when participating in sexual activity after taking an erectile dysfunction merectile dysfunctionication should stop the encounter. They should also not take any erectile dysfunction drug again until they have discusserectile dysfunction the episode with their healthcare provider. It is recommenderectile dysfunction that men with kidney or liver impairments, and men over age 65, start at the lowest possible dosage of erectile dysfunction merectile dysfunctionications.
