Researchers found that nearly one in three people using the pills order them over the web rather than going to their doctor.

Many said they turned to the internet because they were too embarrassed to speak to a medic about their problems.

Dr Ian Banks, one of the study’s authors, said of the findings: “I can see why more men are buying online.

“We should be making it easier for men to get these drugs, but only after a proper diagnosis of what’s causing the problem.”

Diagnosing your own ED is not a good idea, however. If you have trouble getting an erection, it’s important to see a doctor before pursuing any sort of treatment. There could be a medical explanation for your condition, and your health and sexual history may come into play.

1. Pills

Viagra, Cialis (tadalafil), and Levitra (vardenafil) fight erectile dysfunction by relaxing smooth muscle in the penis, a process that increases blood flow and enables an erection.

The effectiveness of these phosphodiesterase type 5 (PDE-5) inhibitors is well documented. “ED drugs are 70% effective in allowing the penis to achieve hardness for sexual activity,” says Irwin Goldstein, MD, director of San Diego Sexual Medicine and the editor in chief of The Journal of Sexual Medicine.

And the pills are generally considered safe. Side effects can include headaches, sinus congestion, indigestion, and blue vision, but all are usually mild. “They’re some of the safer drugs on the planet,” says Dr. Goldstein.

If you’re on ED drugs, don’t take nitrates—such as nitroglycerine pills for chest pain or the recreational drugs known as “poppers.” The combination can lower blood pressure to dangerous levels and can even cause a heart attack.

2. Injections

If oral medications don’t work, a doctor might recommend injecting medication directly into the base or the side of the penis with a tiny needle or inserting a suppository into the urethra.

The injectable drug alprostadil is a synthetic version of prostaglandin E1, a hormone-like substance that functions similarly to ED pills. Some injections mix alprostadil with other medications—such as the vasodilator papaverine and the alpha-blocker phentolamine—to increase its effectiveness.

Your doctor can teach you to perform the injections yourself at home.

3. Suppositories

For guys who prefer not to inject themselves or have a fear of needles, a suppository called MUSE—containing the drug alprostadil—is also available, though it is not considered as effective as the shots. “The injection is a direct delivery of medication to the penis, while the suppository is inserted into the urethra and when it is absorbed, it loses some of its strength,” says Ridwan Shabsigh, MD, director of the division of urology at Maimonides Medical Center and professor of clinical urology at Columbia University in New York City.

Both methods have the same primary complaint: Men using injections or MUSE often say they take away from the spontaneity of sex because it takes time to prepare and administer the medications.

4. Pumps

Penis vacuum pumps get a good laugh in the Austin Powers films, but they happen to be quite effective at increasing blood flow to the penis and they’re available over-the-counter at relatively low cost.

The process of pumping air out of the tube pulls blood into the erectile tissue. To stay erect after removing the tube, it’s a good idea to slip a constriction ring over the base of the penis.

5. Constriction rings

“Cock rings” worn around the base of the penis can slow down the speed at which blood leaves the penis. While constriction rings won’t increase blood flow into the penis, they can prolong an erection once one is achieved (using a vacuum pump, for instance).

Rings should not be used for more than 30 minutes and should be removed immediately if you experience cold, numbness, or pain in the genital area.

6. Implants

The technology of penile implants is improving all the time. “They rival implants in other parts of the body, like the pacemaker,” says Dr. Shabsigh.

There are two types of implants.

Inflatable implants are cylinders that are implanted in the erection chambers of the penis and inflated by a hydraulic pump implanted in the scrotum.

Malleable implants are semi-rigid, bendable rods that are implanted into the penis, which can then be manipulated manually into an erect or flaccid position.

7. Surgery

Vascular surgery is rarely performed but may be a last resort for some men. “There are some patients who can benefit from vascular surgery, but the number is less than 1% of men who have ED,” says Dr. Shabsigh. “It’s the equivalent to a coronary artery bypass and there are only a handful of surgeons in the country who do it.”

London, UK, 28th February, 2010: The Pfizer share prices went sky high when the news of discovery of Viagra broke out in 1998. It also brought along a huge cultural change in the mindset of men across the world. They started talking openly about a subject (impotence and sex), which was taboo earlier. When famous people appeared on television endorsing Viagra and explaining that erectile dysfunction or ED was a common problem among men, people took notice. They were not embarrassed about the problem any longer.

According to an Genericdoc.com official, people were convinced by macho celebrities appearing on television who praised the positive qualities of small blue pill called Viagra. Other companies also entered this lucrative market before long. Even unlicenced players also entered the market, catching the unsuspecting public off guard. The impotence drug market size was multi million dollar and the competition to get a large size of it was fierce.

The Genericdoc.com official further says that just like other medicinces, Viagra and its copycats also had their fair share of side effects but the companies did not want to talk about it because of possible negative effect on their business. Right from the beginning, people taking cheap Viagra reported side effects. Some were not so serious, including the one in which patients reported seeing a bluish tinge after they took the drug, whereas other side effects were more serious because even Pfizer told doctors not to prescribe the medicine to patients with certain medical complications.

Some older patients died of heart attacks after they took Viagra. The problem was Viagra was affecting blood flow within the body which proved fatal for older heart patients. Even Cialis website explicitly warned patients from taking Cialis if they were taking nitrates for chest pain. The resulting combination might suddenly reduce blood pressure in the body thus creating severe complications. The patient may even feel dizzy as a result of reduced blood pressure.

The most common side effects are upset stomach and headache. Some patients have also reported muscle pain or back pain. All the erectile dysfunction drugs, just like other drugs have good and bad effects at the same time. The use of these drugs should depend on specific patient requirements and doctors opinion.

Douglas, 65, talked about his love of wife Catherine Zeta Jones and his second chance at being a dad.

He remembered how he was first smitten with Zeta Jones after seeing her in “The Mask Of Zorro”:

And does his pulse still quicken the way it did in that darkened screening room watching Zorro? “Oh, yeah,” he laughs. “At least in your head, your fire burns as brightly. Let’s not kid ourselves. But God bless her that she likes older guys. And some wonderful enhancements have happened in the last few years–Viagra, Cialis–that can make us all feel younger.”

They have two children, and Douglas also has a son Cameron, 31, currently in jail on drug charges.

Zeta Jones told the magazine that Douglas loves being an at-home parent when not working. “Michael tells me that [new fatherhood] keeps him agile. He’s a terrific, extremely hands-on father.”

Douglas acknowledges that wasn’t the case when Cameron was young.

“I’ll assume whatever responsibilities I have to. Would it have been better to have been around more? Absolutely. There were absences, and I was no angel.”
“I think it’s easier for me to be a good father. I’m not so concerned about my career,” Douglas continues. “I like to be home a lot more now. I see the confidence my kids have got versus the struggle for confidence that I had or that Cameron might have dealt with.”

Pfizer Inc’s Viagra or sildenafil and Eli Lilly and Co’s Cialis or tadalafil treat impotence by increasing blood flow to the genitals, but some men taking the drugs have reported blurred vision, blue-tinged vision or altered light perception.

The drugs work by blocking the action of the enzyme phodiesterase type 5 or PDE5 on the blood vessels in the penis. But PDE5 inhibitors may also act on blood vessels in the retina, which could explain some of the reports of vision problems.

To test this, a team led by Dr. William Cordell of Lilly Research Laboratories in Indianapolis and colleagues conducted a randomized study to look for changes in the retina among men taking Viagra or Cialis.

They studied 244 healthy men or those with mild erectile dysfunction aged 30 to 65 who had no vision problems. Of these, 85 took 5 milligrams of Cialis, 77 took 50 milligrams of sildenafil and 82 took a dummy pill daily for six months.

The men underwent comprehensive eye exams, including electroretinography, a test to measure the electrical response of the light-sensitive cells in the eye, before, during and after treatment.

Among the 194 men who completed the study, the researchers found no significant differences between treatment and placebo groups on electroretinography, visual function tests, measurements of pressure within the eyeball or assessments of the anatomy of the eye.

“Our results indicate that there is no cumulative damage or effect of clinical significance,” for the studied doses of either drug, the researchers wrote in the Archives of Ophthalmology.

They said their study was limited because the doses used were lower than some other studies that did find retinal changes. And they said the results could not be generalized to men with eye problems, who were excluded from the study.

Viagra and Cialis each had global sales of more than $1 billion in 2008.

Eli Lilly designed and paid for the study, which did not evaluate Bayer AG’s Levitra or vardenafil, a similar drug.

The daily version will take pressure off users who would otherwise have a “shot clock” or window of effectiveness to worry about, Lilly officials say. Cialis also is offered at a higher dose that provides a 36-hour window.

With the daily dose, men will not need to take Cialis in anticipation of sex because it is already in their system, said Shawn Heffern, Lilly’s U.S. marketing director for the drug.

Lilly said in a statement the daily dose is geared for men who anticipate having sex twice a week or more frequently.

Cialis rang up $798 million in sales during the first nine months last year. In 2006, it registered $971 million for the full year, a 30 percent increase over 2005.

Heffern said the drug is on track to top $1 billion in sales for 2007. He declined to say how the daily dose will affect revenue.

Cialis trails market leader Viagra in sales. The Pfizer Inc. erectile dysfunction drug collected $1.26 billion in sales during the first nine months of 2007.

The daily dose could increase Cialis sales depending on how it’s priced, said George Farra, co-founder and principal of Woodley Farra Manion Portfolio Management. His firm manages nearly 285,000 Lilly shares.

Between Jan. 1 and May 26, 2008, 150 non-diabetic patients with severe hypoglycemia were admitted to public hospital in Singapore. There were four deaths, and seven patients remained comatose, Dr. Kok Onn Lee of National University Hospital in Singapore report in Thursday’s New England Journal of Medicine.

All of the patients except one were men, and they ranged in age from 19 to 97, with an average age of 51.

The drugs included counterfeit Cialis and herbal remedies called Power 1 Walnut and Santi Bovine Penis Erecting Capsule.

The drug packaging listed names of fictitious overseas factories, so it is not known whether the contamination was deliberate or accidental, the doctors said.

“We believe that physicians should be cognizant of this phenomenon when evaluating patients with severe unexplained hypoglycemia, particularly if a clustering of cases is noted,” the team wrote.

They also called for better collaboration between national and international drug regulators and enforcement agencies to address clandestine manufacturing processes, the cross-border movement of drugs, and the sale of adulterated medications online.

A couple of days ago BNET noted that Pfizer and Lilly appear to have frozen Bayer’s Levitra out of the market. The two ED brands have come to dominate global sales of penis pills. This was my explanation:

The gains for Pfizer and Lilly come despite the downturn reducing the number of employees with health coverage. Both companies have made efforts to bolster their franchises: Lilly received approval to market a “once-a-day” version of Cialis; and Pfizer has been aggressive in calls to increase enforcement against illegal, counterfeit and fake supplies of the blue pills (among other drugs).

But the Swiss Competition Commission has come up with a much more interesting theory: They colluded on prices:

“The recommended public selling price covered the drugmakers, pharmacies and physicians,” Olivier Schaller, a spokesman for the commission, said in a telephone interview. “It was widely followed.”

The official terminology in the accusation is priceless: “inadmissible vertical competition agreements.” And the spokesperson for Lilly in Switzerland? Petra Streit. Fantastic.

The fact that Cialis has managed overtake Viagra in some national markets shows how popular the drug is and gives credibility to the ambitions of the Cialis marketing team who say that they want to make Cialis the world’s best selling erectile dysfunction medication. One of the reasons why Cialis is selling so well is that in America a new version of the drug has been launched called Cialis Once A Day which has proved to be very popular with certain groups of men.

The future for Cialis is also bright because clinical trials have shown that it is effective in treating Pulmonary Arterial Hypertension as well as Benign Prostatic Hyperplasia and applications have been filed by Eli Lilly to be allowed to sell Cialis in a different packaging and under different names to treat these two conditions.

The great advantage that Cialis has over its rivals Viagra and Levitra is that it works for much longer than the other two. While Viagra and Levitra have a four hour time window time for effectiveness, Cialis can work for as long as 36 hours with one dose.

Cialis is the best selling erectile dysfunction medication in France and has been nicknamed ‘Le Weekend Pill’ there.

Generic drugs manufacturers must get WHO’s (World Health Organization) approval. Sometimes, the same pharmaceutical company that makes the brand drug also produces its generic version; in other cases, the company specializes in producing generic drugs.

How does generic Cialis work? In a few words, it relaxes blood vessels in the penis by inhibiting PDE5, an enzyme generally found in the arterial wall smooth muscle tissue of the penis prnewswire press release the lungs. The result is an increase in the blood flow, which helps the erection. Men who suffer from erectile dysfunction problems should buy Cialis because it is safe, effective and its effect lasts for 36 hours. The same thing goes true for generic Viagra.

The prescribed dose of generic Cialis is 20 milligrams, which is comparable to a 100 milligrams dose of generic Viagra. For the pr newswire press release to have its desired effect, one should take it 30 minutes before lovemaking. Compared to Viagra, Cialis is more advantageous because its effect lasts much longer – 30 hours more than Viagra, in fact.
