Vardenafil

Vardenafil was co-marketed by Bayer Pharmaceuticals. GlaxoSmithKline. and Schering-Plough under the trade name Levitra. As of 2005, the co-promotion rights of GSK on Levitra have been returned to Bayer in many markets outside the U.S. In Italy, Bayer sells vardenafil as Levitra and GSK sells it as Vivanza. Thus, because of European Union trade rules, parallel imports might result in Vivanza sold next to Levitra in the EU.

An orally disintegrating form, marketed as Staxyn and Levitra Soft. has been gaining approvals in countries such as the United States [1] and Canada. [2]

Vardenafil's indications and contra-indications are the same as with other PDE5 inhibitors; it is closely related in function to sildenafil citrate (Viagra) and tadalafil (Cialis). The difference between the vardenafil molecule and sildenafil citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both sildenafil and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's.

Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation. where it may significantly increase the time from penetration to ejaculation. [3]

Adverse drug reactions Edit

The common, adverse drug reactions (side-effects) are the same as with other PDE5 inhibitors. The frequent vardenafil-specific side-effect is nausea; the infrequent side-effects are abdominal pain, back pain, photosensitivity. abnormal vision, eye pain, facial edema. hypotension. palpitation, tachycardia. arthralgia. myalgia. rash, itch, and priapism .

One possibly serious, but rare, side-effect with vardenafil is heart attack. Also, in rare cases, vardenafil use may cause priapism. a very painful emergency condition that can cause impotence if left untreated. [4]

On 18 October 2007, the U.S. Food and Drug Administration (FDA) announced that a warning about possible deafness (sudden hearing loss ) would be added to the drug labels of Vardenafil, and other PDE5 inhibitors. [5]

Drug interactions Edit

Vardenafil, as with all PDE5 inhibitors, should not be used by men taking nitrate medications, because combining them with vardenafil might provoke potentially life-threatening hypotension (low blood pressure).

Further, Vardenafil causing lengthening of the QT interval. Therefore, it should not be taken by men taking other medications that affect the QT interval (such as amiodarone ).

Dose forms Edit

Levitra 20mg Oral Tablet

It is available in 2.5 mg, 5 mg, 10 mg, and 20 mg doses in round orange tablets. The normal starting dose is 10 mg [6] (roughly equivalent to 50 mg of sildenafil). Vardenafil should be taken 1 to 2 hours prior to sexual activity. with a maximum dose frequency of once per day. In some territories, such as the UK, only certain doses may be available.

Vardenafil is also available under the name Staxyn as a tablet which dissolves on the tongue rather than being swallowed in the form of a pill. [7]

Levitra

Levitra is sold in the US by GlaxoSmithKline PLC and Schering-Plough Corp and outside the US by Bayer AG.

The firm said the growth in sales of Levitra ( a competitor to high-profile pill Viagra ( had not kept pace with its other blockbuster treatments for illnesses such as asthma and diabetes.

While Viagra and Levitra ads have taken the macho approach, Lilly is leaning more toward an emphasis on romance, realizing that while men are the users, the women in their lives also have a keen interest in the sale.

Levitra will start competing with Pfizer's Viagra ``as soon as possible'' and Glaxo and Bayer believe they could see sales of more than $1bn.

Levitra. produced by drugs giants GlaxoSmithKline and Bayer, is awaiting final approval from the regulators and should be on the market early next year.

They uncovered 47 suspected cases of sensorineural hearing loss - a rapid loss of hearing in one or both ears - linked to Viagra and related drugs Cialis and Levitra .

Then a short course of tablets such as Levitra. Cialis or Viagra should give you back your erections and help improve your confidence again.

To sell the erectile dysfunction drug Levitra in Hong Kong, the Wall Street Journal reports, Bayer HealthCare AG has had to tailor its message to the local culture in unexpected ways.

The 2001 edition preceded the introduction of Viagra's competitors, Levitra and Cialis, for treating erectile dysfunction (ED).

The group also launched two new products in the US,including an enhanced version of Wellbutrin and Levitra - a drug to treat erectile dysfunction which it hopes will seize market share from Viagra, produced by rivalPfizer.

And aren't the folks at Levitra. the title sponsor for the Skins Game, just pleased as punch that Annika Sorenstam came up second?

Viagra and Levitra. an erectile dysfunction drug approved by the Food and Drug Administration in August, work by increasing blood flow to the penis.
