The Home of Viagra in Great Britain to Be Closed Soon

Posted by Alice on March 31st, 2011

The research center in Great Britain, where Viagra – the most popular erectile dysfunction drug – was developed, will be closed by Pfizer due to budget cuts.

Prime Minister of Great Britain, David Cameron, commented on the decision of Pfizer – manufacturer of Viagra – to close its research center in Sandwich.

He said that the news is depressing because many employees will be made redundant, while others will be moved to other locations.

Also, it is sad to see the “home of Viagra”, as the research center used to be referred to, disappear.

The research center in Sandwich was the largest R&D center in UK owned by Pfizer.

Announcements made by Pfizer representatives suggest that the closure of the UK-based research and development center is not due to any issue between the manufacturer and the British government. Instead, it comes along with the announcement that the budget of the pharmaceutical company would be decreased by £1.2 billion.

Let us remind that the #1 erectile dysfunction drug, Viagra, was developed in Sandwich, UK.

Why Prescription Drugs Are Prescription?

Posted by Barbara on January 30th, 2011

Prescription drugs

This article briefly explains the differences between prescription and over-the-counter drugs and looks at them from the legal perspective.

You have certainly heard about prescription drugs and over-the-counter drugs, but you might have never digged into the reason why certain medications can be obtained freely, whereas others can only be sold to those who have a doctor’s prescription.

As a general rule, over-the-counter drugs are those that can be used to treat medical conditions that do not require care from a doctor.

Prescribed drugs are those that are used to treat more serious conditions that can only diagnosed by a health care specialist. Respectively, a prescription for such drugs is given out by a doctor who decides on the dosage and treatment duration.

Oftentimes, one and the same drug can be sold with a prescription or over-the-counter depending on its strength. A vivid example of such drug is Ibuprofen.

Legislation on prescription drugs varies by country but is very strict regardless of the region. It is important to note that one and the same drug (sometimes sold under different brand names) might be considered prescription in one country and over-the-counter in the other because drug classification oftentimes differs.

People have to be aware of the fact that food supplements, herbal preparations, vitamins and minerals are rarely considered drugs in any country and that is why are not subject to the same regulations as medications are. This means that use of such substances can be unsafe.

Alternative Ways to Treat Erectile Dysfunction

Posted by Barbara on January 23rd, 2011

ED treatment options

This article lists the possible treatment options for erectile dysfunction so that men understand that pills like Cialis or Viagra are not the only choice they have.

When we talk about erectile dysfunction, drugs such as Viagra, Cialis and Levitra are the most wide-spread treatments mentioned.

However, men who are diagnosed with this sexual disorder or who appear to be in the group of risk, should be aware of the fact that there are other treatment options as well.

The three treatment options, apart from medication, are devices (penis pumps), surgery and alternative medicine.

Penis pumps help draw blood into penis right before the actual sexual intercourse. Only a small number of these devices is approved by the US Food and Drug Administration. They are only available with a doctor’s prescription, so stay aware of the ones that are sold freely.

Surgery is usually considered as a last resort when all other treatment options failed. The man who has to go through a surgery to restore his sexual function will typically have prosthetic implants inserted.

Finally, the treatment option which does exist but is not recommended by the FDA is alternative medicine, which oftentimes comes in the form of herbal or natural “Viagra.” Even though it might appear to help treat ED, no clinical trials proving the drugs’ effectiveness and safety have been performed. Men who decide to choose this option should clearly understand the associated risks.

Main Factors Causing Erectile Dysfunction in Men

Posted by Barbara on January 10th, 2011

Causes of ED

Listed below are major causes of erectile dysfunction, which might include physical as well as psychological factors or both.

You might be wondering what causes of erectile dysfunction typically are.

There are two right answers: sexual disorder can be caused by psychological factors as well as physical.

Among the most wide-spread physical conditions that might (or might not) result in erectile dysfunction are:

  • vascular disease because it causes a reduction in blood flow through the body. Typically, it affects men over 60 (50-60% of those suffering from ED are also diagnosed with vascular disease)
  • diabetes can also reduce blood flow because it usually damages small blood vessels and nerves, thus impairing nerve impulses.
  • drugs, just as well as physical conditions, might affect nervous and vascular systems, impairing nerve impulses and blood flow.
  • neurologic conditions might affect nerve impulses from the brain to the penis, thus preventing men from having normal erection.
  • surgery, chemo, or pelvic trauma all might damage nerves and/or veins can reduce blood flow or impair nerve impulses.

As for psychological conditions, they typically include depression, stress, guilt, and anxiety, which might cause loss of libido or ED. Psychological factors might be secondary to physical ones.

Is Cialis Habit-forming or Not?

Posted by Barbara on December 31st, 2010

Addiction to Cialis

No. If a man takes Cialis on a regular basis to have an erection that doesn’t mean that a man is Cialis addicted; that means a man still has problems with erection.

The main component of Cialis, tadalafil, doesn’t lead to addiction to the drug. Therefore, Cialis is not a habit-forming drug. Let’s try to find out the causes of impotence to explain the way Cialis acts.

Among main causes of impotence are medical and psychological factors. Medical ones include diabetes and high blood pressure. If impotence is due to physical condition it is clear that Cialis is not the medicine to improve it. So, men suffering from high blood pressure or diabetes will need to use Cialis on regular basis.

It is important to know that Cialis doesn’t bring long-term improvement of sexual function. It acts bringing the blood flow more intensively to penis. And Cialis doesn’t affect the ability of a man to have erection in the future.

So, men taking Cialis shouldn’t be worried about addiction to this medicine because Cialis doesn’t  change the sexual function in general, it brings short-term effect.

The History of the “Blue Pill” Revealed

Posted by Barbara on December 19th, 2010

Viagra

1983 was critical for understanding the problem of erectile dysfunction. Some time ago the erectile dysfunction was explained by mental reasons. But in 1983 in Las Vegas Dr. Giles Brindley demonstrated at American Urological Association meeting the influence of drug called phentolamine.

What are the abilities of phentolamine? It is muscle relaxant.

Inside our bodies we have several types of muscles: skeletal, cardiac and smooth. When we talk about erection in men the key role belongs to smooth muscles.

So here the question appears: how did the relaxant drug phentolamine provoke the erection?

Now let’s explain: Arteries of soft penis are compressed to prevent blood to enter corpora cavernosa.

The injection of phentolamine helped smooth muscles of artery walls relax so blood passed inflating penis that resulted in erection.

So after such a discovery men suffering from erectile dysfunction started to use muscle-relaxing injections.

Viagra brings this solution in much more easy way. Men can take the pill instead of injection. And one more benefit for Viagra is that the famous blue pill helps with erection when the men are sexually aroused; phentolamine causes uncontrolled erection.

Can Viagra be Used as Treatment for Women on Antidepressants?

Posted by Barbara on December 9th, 2010

Viagra and Females

Most surveys show that Viagra is not the right treatment for women. But the results of recent research demonstrated that this famous blue pill may help women suffering from side effects after antidepressant treatment.

Usually, 30 to 70 percent of women and men suffer from side effect of antidepressant treatment. During the first month of taking the antidepressant medicine two of three patients refuse to continue the treatment because of sexual side effects.

The research was held on 98 women using antidepressants and suffering from sexual side effects that include the problems with achieving orgasm and lack of sexual arousal. Within the bounds of research women were taking Viagra or a placebo for eight weeks couple of hours before to have sex.

The results of the survey demonstrated that 72 percent of women taking Viagra had an improvement. Respondents reported about achieving orgasm and the excitement; moreover, use of Viagra assisted in general improvement of sexual function.

This research funded by Pfizer was the first survey proving positive treatment of sexual side effects due to antidepressants and demonstrating the advantages of Viagra for women.

Anyway the results are not taken as a conclusion because the group of respondents was rather small, so before official statements about Viagra’s positive effect in women the research must be held in larger groups of women.
