What is the Levitra?
Levitra (Vardenafil) is a drug for treatment of erectile dysfunction. Being a PDE-5 inhibitor, this drug relaxes muscles and increases the blood flow to penis.
Levitra does not cure erectile dysfunction, but rather helps get and maintain erection. The drug should be taken 1-2 hours prior to sex so that it takes effect. Levitra is not an aphrodisiac and does not improve men's sexual desire or lead to erection without proper sexual stimulation. No more than one dose of Levitra should be taken daily.
As any other erectile dysfunction drug (Viagra or Cialis, for example) Levitra has its side effects. Some of them include fainting, heart attack, dizziness, headache, chest or neck pain. Painful and prolonged erection might also occur and cause damage to men's health. Levitra is a prescription drug, which means that it should not be used unless recommended to do so by a doctor. Conditions that the doctor has to consider before prescribing Levitra include heart problems, blood clots, angina, liver and kidney problems, bleeding or blood cell disorders, etc. You can buy Levitra online once you have been prescribed to take this drug by a doctor.
Who makes Levitra?
Levitra is produced by Bayer Corporation, a German pharmaceutical company, and distributed by Glaxo SmithKlein. The drug was approved by the US Food and Drug Administration on August 20, 2003. US sales of the drug reach approximately $174 million.
The drug, which was initially developed by Bayer, is marketed by Glaxo SmithKlein since it has a better marketing infrastructure. In 2005, the co-promotion rights of Glaxo SmithKlein on Levitra have been returned to the drug's manufacturer in most countries except for the US. In many European markets GSK sells Levitra under the brand name of Vivanza.
The famous face of Levitra is Mike Ditka, coach of Chicago Bears. He claims to have been suffering from erectile dysfunction for years. The drug comes in the form of orange pills with a flame logo and Bayer's trademark.
How Does Levitra Work?
Levitra is one of the few drugs licensed for treatment of erectile dysfunction - the most widespread sexual disorder in men. The drug is characterized by high effectiveness levels helping many men suffering from impotence get and maintain erection.
Levitra (Vardenafil) works by blocking PDE-5, a chemical that reduces blood flow to the penis, thus allowing men to get and maintain erection for longer.

To better understand the mechanism behind Levitra, it is important to know what erection and erectile dysfunction are.
Erection occurs every time that nerve signals are sent from the brain to the penis. They affect a special chemical that helps constricted penis muscles to relax, releasing the blood flow to the penis. It is exactly the blood that causes erection.
Erectile dysfunction is a disorder that is caused by a chemical known as phosphodiesterase type 5, or shortly PDE5. It negatively affects the chemicals, which enable the flow of blood to the penis, thus preventing penis muscles from relaxing. Levitra (Vardenafil) blocks the PDE5 chemicals, thus preserving the “good” chemicals responsible for the relaxation of penis muscles and blood flow.
How Effective Is Levitra?
As clinical trials showed, Levitra is effective in most men, including those who are diagnosed with diabetes and prostate cancer.
Clinical trials were carried on 6,000 men. As many as 65% of the patients who took 5 mg of Levitra said that they gained and maintained a good erection that lasted for a long time. This proportion rose to 75% and 80% in men who took 10 mg and 20 mg of Levitra respectively.
Patients also said that the quality of their sexual performance improved.
Many men, who took Levitra, said it worked in only 15 minutes. The average time span, however, is 30-60 minutes.
Levitra can be taken by people with diabetes. Clinical trials showed that 61% of men enjoyed satisfactory erection, while 49% reported good erection when taking 10 mg of Levitra. The results were better in those patients who took 20 mg of Levitra. The effectiveness of Levitra might be reduced by fatty food. Doctors suggest that patients consume Levitra at least 3 hours after their last meal.
How to Take Levitra?
Generally, men are prescribed 10 mg of Levitra prior to each sexual intercourse, but not more than 1 dose every 24 hours.
However, the dosage might be different depending on the age, health problems and other conditions. For example, men aged 65 and over, patients suffering from liver problems or those in certain drugs might be prescribed as little as 2.5 mg of Levitra.
The exact dose of Levitra can only be determined by a doctor upon careful medical examination.
General recommendations for men taking Levitra:
- Levitra can be taken at any time during the day
- No more than 1 dose of Levitra should be taken every 24 hours
- Fatty and rich foods might reduce the effectiveness of Levitra
- Levitra works best when taken according to the prescribed dosage
