Levitra is a medication with Vardenafil as its active substance. Vardenafil was developed by Bayer Pharmaceuticals. Levitra is a registered trademark owned by this company.
Levitra became the second PDE-5 inhibitor with Viagra being the first. Levitra is used for treating erectile dysfunction in men.
Like any other phosphodiesterase-5 inhibitor, Levitra does not work without sexual stimulation. Vardenafil fills the vessels with blood and makes the muscles to relax improving circulation in the penis and filling the cavernous bodies. This makes erection stronger and longer.
Levitra was approved by the FDA in 2003. Recognition by this US regulatory authority controlling the safety of foods, dietary supplements and medications means that Levitra is efficient and safe.
Important information you should know before taking this medication
Male erection is a result of coordinated work of many body organs and systems. The brain sends signals to the nervous cells triggering the production of sex hormones and delivering blood to the small pelvic organs. Erectile dysfunction is a sign of a failure in the work of these organs and systems. It may be, for example, a cardiovascular disorder or diabetes. Often erectile dysfunction is a result of nervous system disorders including Parkinson’s disease. Dysfunction may also occur as a response to stress, anxiety, and depression. So, once such a problem occurs, you should consult your doctor first to find the underlying cause.

What are generics. Levitra generics.
Generic drugs are medications that have the same active substance as already known medication brand.
Drug development is, first of all, the development of a new active substance. The substance should undergo numerous tests and studies. Only when effectiveness and safety are proved, a new drug is brought to the market and it is an original drug. The pharmaceutical company that developed the drug has an exclusive right to manufacture it. While the patent is in force, other companies are not allowed to use this active substance for introducing their medications to the market. The purpose of this is to give the drug developer to cover their costs.
When the patent expires, other pharmaceutical companies may produce generics.
The patent to manufacture and sell Levitra – a drug with Vardenafil – belongs to Bayer.
When the patent expires, other pharmaceutical companies may produce generics.
The patent to manufacture and sell Levitra – a medication with Vardenafil – belongs to Bayer. It expires in 2020 but the company may extend it. When the patent expires, Levitra generics may appear. Naturally, this is not so easy as each generic must have the approval of regulatory authorities and undergo safety and effectiveness tests and studies.
This is the case with the USA and other developed countries. As for the countries of the third world, they do not care much about the international patents. As a result, even while the patent is still in force, generics that didn’t undergo any safety and effectiveness studies may appear.
These medications are sold mainly in those developing countries. However, due to their low prices, they may appear in developed countries as well, illegally, of course. They are in demand also because people can buy them without a prescription.
The problem is that adverse events may be more serious after taking these cheap drugs because chemical raw material is not typically well purified.
Проблема в том, что побочные эффекты у этих препаратов могут быть гораздо более выраженными за счет низкой степени очистки сырья.
