Levitra is one of the most popular branded drugs used for treatment of erectile dysfunction in men. Levitra is an FDA-approved oral prescription medication for USA Market. The medication is produced by Bayer Pharmaceuticals, GSK and SP.
Levitra’s main component is vardenafil hydrochloride which belongs to the drug class of PDE type 5 inhibitors indicated to fight ED problems in men. Levitra works by helping to relax muscles and increase blood flow into the penis during sexual stimulation. This helps men to achieve and maintain an erection.
Vardenafil is closely related in function and mechanism of action to sildenafil (Viagra) and tadalafil (Cialis), but has fewer side effects than the mentioned medications. The other reason why Vardenafil is better than Sildenafil and Tadalafil is: it is structurally different and thus starts acting much quicker than the other two PDE 5 inhibitors. Clinical trials of the medication have demonstrated improved quality of erections, rapid and reliable response.
Levitra is available in 2.5 mg, 5 mg, 10 mg, and 20 mg tablets and is taken only when needed. The medication works for up to 6 hours. The recommended time to take before sex is 25 to 45 minutes.
Levitra can be taken with food and even small amounts of alcohol. Still alcohol in excessive amounts is restricted while being treated with Levitra.
