What is Levitra

Levitra is a brand (trade) name of a drug with Vardenafil as its active substance to treat erectile dysfunction in men.

Levitra is a registered trade mark of Bayer Pharmaceuticals. The drug is used to treat erectile dysfunction.

Vardenafil is the second PDE-5 inhibitor that was introduced to the pharmaceutical market. The first was Sildenafil (Viagra). Levitra is used to manage mild and moderate erectile dysfunction in men.

As other PDE-5 inhibitors, Vardenafil does not induce erection without sexual stimulation. Levitra widens arteries and blood capillaries in the genitals and increases the blood flow during sexual stimulation. It helps to induce and maintain a strong erection during sex.

Levitra was approved by the U.S. Food and Drug Administration (FDA) responsible for control and supervision of food, dietary supplements, and drugs in 2003. It means that Vardenafil is effective and safe.

What you should know before taking the drug

 

Erection is a complex process involving a coordinated work of the central nervous system, vessels, and sex hormones. Erectile dysfunction can be a sign of such diseases as heart disease or diabetes. Erectile dysfunction is also believed to be the symptom of stress and anxiety. It can also be a side-effect of some medical drugs. Nervous disorders including multiple sclerosis and Parkinson’s diseases are also the symptoms of erectile dysfunction. So when you notice erectile dysfunction, consult your doctor to find out the cause.

Levitra interaction with other drugs. Contraindications

Before you start taking Vardenafil, consult your doctor.

Notify your doctor of the following:

  • Cardiovascular diseases, for example, coronary heart disease, hypertension, hypotension.

This information will help the doctor to decide whether you have contraindications and to prescribe the optimal dose.

Avoid taking Levitra if you are already taking nitroglycerine and other nitrates (isosorbide mononitrate) as your blood pressure may suddenly drop to a dangerously low level due to an extreme widening of peripheral vessels.

Levitra generics — what is it?

Generic is a drug that contains the same chemical substance as the drug that was originally developed.

Developing a new active substance, a pharmaceutical company carries research and tests. The drug undergoes clinical evaluation.  The company spends a lot of money for laboratory and clinical research. When the drug is approved, the company obtains a patent that gives it an exclusive right to sell the drug. As long as the patent is in effect, no other company can sell drugs with the same active ingredient. The company can set any price for its drugs to recover the money they had spent and earn the profit.

When the term of the patent expires – usually 12-17 years since the date the drug entered the market – any company is entitled to manufacture drugs with the same active ingredient as the drug that was originally developed. These drugs are generics.

The international patent for Levitra expires in 2018. However, all countries have different patent legislation. In the USA, for example, the term of the patent has been recently reduced from 17 to 12 years.

Due to this fact, some pharmaceutical companies (mainly from India) already manufacture Levitra generics. In Russia, these generics are illegal as the patent is still in effect on the territory of the Russian Federation.

The term of the patent has expired in the USA but Levitra generics are still absent there as drug registration process is very complicated. It requires a lot of time and money to get the FDA approval.

For this reason, Levitra generics can be found only on Asian market. India is the country where Vardenafil, the active substance of Levitra, is manufactured. Generics are much cheaper than original drugs and they are illegally imported to the countries where the patent is still in effect.

Of course, people may save money but we should treat Indian generics with caution.

Often the companies do not care much about proper substance purification as they can not afford to buy modern equipment.

As a result, many generics (not all) are less effective but adverse effects may be more serious.

Where can I buy Levitra?

Officially Levitra is a prescription drug. Pharmacies require a prescription to sell the drug.

Generics of Levitra are easily available in online drugstores without prescription that makes them so popular.

Men with no erection problems buy Levitra generics to make their sex better and to impress their partner.

Men with erectile dysfunction are often too confused to go to a doctor to get a prescription. It is much easier to buy a generic online.

Conclusion

Levitra is a popular drug to treat mild to moderate erectile dysfunction. It is second only to Viagra and Cialis. Levitra is popular in European countries maybe because  Bayer Pharmaceuticals was founded in Germany.

Levitra helped many men in Europe and around the world to become confident again and improve their sexual life thanks to its efficacy and not significant side effects.
