What are vardenafil tablets?

Vardenafil hydrochloride is a member of a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors. The pharmaceutical forms of this medication are film-coated tablets, as well as orodispersible pills. 

The trade name of vardenafil is Levitra, a product manufactured by the pharmaceutical company Bayer. Also, Staxyn is the brand name of the orodispersible vardenafil tablets, manufactured by the same company.

What are vardenafil tablets used for?

Levitra vardenafil is generally prescribed as a treatment for erectile dysfunction (impotence). This condition occurs when you are unable to achieve and sustain an erection during sexual intercourse. Due to the possible drug interactions and contraindications, you can get ahold of this medication only if it is prescribed to you by a doctor or pharmacist.

On the other hand, this medication can be prescribed to you in case of pulmonary arterial hypertension (PAH). This health condition happens when the high blood pressure in your arteries goes from your heart to the lungs. You may use this medication for other purposes not listed in this article.

How does vardenafil Levitra work?

Getting an erection is a complex process that involves your heart, blood vessels, nerves, hormones, as well as your mood. Erectile dysfunction (ED) is a health condition that affects some of these factors. Luckily, PDE5 inhibitors like sildenafil (Viagra), tadalafil (Cialis), avanafil (Spedra) or vardenafil (Levitra) have been proven to help men with various degrees of ED.

When you have an erection, the cGMP enzyme causes tissues in your penis to relax. As a result, blood flows into the penis and stays there, long enough for you to engage in sexual intercourse. After that, the blood gets released; returning to normal and the erection subsides. Simply put, when you use vardenafil pills, they work by inhibiting a natural chemical, namely PDE5 that causes blood to flow out of your erect penis. At the same time, the cGMP enzyme does not get broken down, making your penis stay relaxed and erect.

Please note that this treatment works only if you are sexually stimulated! Also, vardenafil tablets do not protect you against sexually transmitted diseases (STDs).

How to take the Levitra tablet

Vardenafil tablets are available in the following dosages: 5, 10, and 20 mg. However, the initial recommended dose of vardenafil is 10 mg. Your health physician may reduce or increase the dose, to achieve the intended results.

You should take one pill, by mouth, with a glass of water, around 30 – 60 minutes before engaging in sexual activity. You use it with food, but drinking alcohol is not advised. To explain, alcohol can reduce the effect of the medication and increase the risk of side effects. The consumption of grapefruit juice should be avoided, as well, since it can interfere with the effect and results of vardenafil.

Vardenafil typically remains in your bloodstream for up to five hours. You should use it only when needed. However, do not take more than a maximum of one tablet every 24 hours!
