This study was conducted to evaluate the effects of vardenafil (Levitra), a phosphodiesterase-5 (PDE-5) inhibitor, on cell proliferation in the hippocampal dentate gyrus and on 5-hyroxytryptamine (5- HT, serotonin) synthesis and tryptophan hydroxylase (TPH) expression in the rat dorsal raphe nucleus. Male Sprague-Dawley rats were divided into 6 groups (n=5 in each group): a control group, a 0.5 mg/kg-1 day vardenafil-treated grou p, a 1 mg/kg-1 (more…)

A sensitive high-performance liquid chromatography-tandem mass spectrometric (HPLC-MS/MS) assay has been developed for the quantitative analysis of vardenafil in human plasma. Vardenafil and the internal standard, alprazolam, were extracted from 0.2 mL aliquots of alkalinized plasma by a single solvent extractio n into hexane : dichloromethane. Reversed-phase chromatographic separation was (more…)

Conclusion:
Although hypoxia and ischemia play a special role in the pathogenesis of tinnitus, the PDE5-inhibitor-induced increase of nitric oxide-mediated vasodilatation exerted no specific influence on tinnitus symptomatology. Con sidering the unclear risk of rarely associated hearing impairment, systemic application of vardenafil or other PDE5 inhibitors prove to be not appropriate for therapy of chronic tinnitus.

Vardenafil (Levitra) is an effective treatment for erectile dysfunction (ED) in men taking one or more
antihypertensive drugs. In a double-blind, placebo-controlled clinical trial involving 354 men, Hermann van Ahlen,
MD, and colleagues at University of Muenster, Germany, found vardenafil to be 83% effective versus a 58% for
placebo. (Source: Geriatrics Magazine)

A case report in the BMJ describes the dev elopment of epileptic seizures in a healthy 60 year old man following high doses of oral vardenafil (Levitra®). He had been prescribed 10mg for sexual dysfunction, but because of lack of efficacy, he had increased the dose himself to 40mg. Three hours later, he had a tonic-clonic seizure, and was admitted to hospital. Neurological and cardiac tests were all normal. He was told to stop using vardenafil. (more…)
