What is Vardenafil? What is Sildenafil Citrate?

Sildenafil is the name for the active ingredient of generic Viagra and Vardenafil is the main active component of generic Levitra. Both of them belong to the so-called PDE-5 inhibitors and are, at the time of this writing, the most effective ED drugs.

How do Sildenafil Citrate and Vardenafil work?

Both work in a similar way - they "freeze" the PDE-5 ferment, which leads to the increased production of a cGMP; the high level of the cGMP chemical make the certain muscles of the penile arteries to relax, which leads to better blood inflow to the penis. This leads to an easier to achieve, stronger and longer erection.

What is the main difference between Sildenafil Citrate and Vardenafil?

Background: Brand Viagra (Sildenafil) got the US Food and Drugs Administration approval in 1998 and is by far the most popular ED treatment, with millions of pills sold all over the World each month. Levitra (Vardenafil) got the FDA approval in 2003, and it is gaining popularity pretty quickly.

Effect: Viagra works within about 60 minutes after taking the pill, while Levitra starts working from 15 minutes to an hour; the effect of Viagra lasts for up to four hours and Levitra's for up to five hours.

Side effects: as all synthetic drugs, both Viagra and Levitra can cause adverse side effects; in 97% of the cases these side effects are mild and do not require special treatment.

Success rate: there is no considerable difference in the success rate of both Viagra and Levitra - they work in approximately 70% to 80% of the cases. Unfortunately a universal erectile dysfunction treatment that works perfectly for all does not exist.

Cost: there is no noticeable difference in the price for Viagra and Levitra.

Food and alcohol: unlike Viagra which works better and faster on an empty stomach and does not work well after the intake of high-fat food, Levitra works regardless of the food intake. The heavy consumption of alcohol should be avoided while taking Viagra and Levitra since it might intensify the side effects.

Prescription: in most countries both Viagra and Levitra require prescriptions.

Dosage: Viagra is sold in 25mg, 50mg, and 100mg pills, and most doctors will initially prescribe the 50mg tablets, and then adjust the dosage. Levitra is manufactured in the form of 5mg, 10mg, and 20mg tablets and the 10mg is the usual initial dosage.

Is there a difference between brand Viagra and Levitra and their generic counterparts?

Sildenafil Citrate is the main component of Viagra and generic Viagra. Vardenafil is the main component of Levitra and generic Levitra. What is the difference between the brand-name medications and the generic drugs then?

The generics work in the same way as the brand-name medications, they are subject to control by the regulating authorities, they meet the same high-standards, they are as safe and they are much cheaper.

The brand names Viagra and Levitra can be used only by Pfizer and Bayer AG, GSK, and SP respectively and all other Sildenafil Citrate and Vardenafil based medicines are known as generic Viagra and Levitra.
