A naturally occurring molecule in the human system, nitric oxide, activates an enzyme referred to as cyclic Guanosine monophosphate (cGMP). This enzyme catalyzes a chemical cascade that results in the expansion of arteries around the male genitals. The actions of cGMP are attenuated by another enzyme known as phosphodiesterase (PDE).
Vardenafil hydrochloride actively suppresses PDE, thereby indirectly prolonging the vasodilatory effects of cGMP, and therefore producing a long-lasting erection. It does not however prevent the spread of sexually transmitted diseases, neither does it possess a contraceptive effect. It is exclusively used to boost and maintain an erection.
This medication is non-intoxicating and its effect usually subsides four hours post-intake.
Prominent brand name drugs such as Levitra contain vardenafil as their pharmaceutically active constituent.

Comparison of Levitra with the world's most famous Viagra
Levitra vs Viagra
Levitra and Viagra employ a similar procedure to tackle impotence. Both medications are taken approximately an hour before sex.
Viagra, first introduced in 1998, is by far the most universally accepted solution for erectile defect, Levitra is however more efficacious because only 10mg of it provides equal effects as 50mg of Viagra. Both drugs last about 4-6 hours post-ingestion in the body. Unlike Viagra, Levitra can be orally administered with alcohol.
Levitra and Viagra have similar side effects (including headache, flushing, nose block, gastro-intestinal disturbances, back pain, etc) that tend to increase with higher doses. Negative reactions are more frequent with Viagra than Levitra.
Vardenafil vs Sildenafil
A generic variant of Viagra called Sildenafil is approved to treat pulmonary arterial hypertension, while the Genetic-equivalent of Levitra is solely used to alleviate impotence.
Choose the best dosage of Vardenafil that will suit you
Variety of dosages are available on the market in 10mg and 20mg strengths. You can make a choice based on the amount that works for you with few or no side effects.
Men 65 years or older and individuals with a pre-existing record of liver or vascular conditions should consider using a 5mg dose once per diem. When dangerous side effects are encountered with 10mg or 20mg, a lower dosage (5mg) is adopted.
A dose of 10mg is used in many instances to establish a baseline for treatment. At least 76% of participants gave a positive response during the post-marketing review of the 10mg formulation. If the resultant erection is not rigid enough, you may adopt the 20mg tablets. But before you upgrade the dose, it is advisable to try the 10mg formulation at least four separate times.
In a study conducted, 40mg of dose lowered arterial blood pressure by at least 4.3mmHg and caused severe backache. Neurological and heart impairments weren't observed even at higher doses up to 60mg.

The following measures and every other precaution mentioned on the drug leaflet should be observed:
- Find the right dose for you depending on your chances of successful intercourse, reactivity, age, and history of hepatotoxicity.
