Also known as:  Vardenafil.


Levitra is an ideal preparation in the treatment of different forms of erectile dysfunction (ED). Levitra allows the user to achieve and maintain a hard erection. Levitra can be taken by men who suffer from type 1 or type 2 diabetes, high blood pressure or high cholesterol.

The active ingredient Vardenafil, a phosphodiesterase type 5 inhibitor (PDE-5 inhibitor), stimulates the release of nitric oxide (NO) in the corpus cavernosum in response to sexual stimulation. Nitric oxide activates the lyase enzyme which results in increased levels of cyclic guanosine monophosphate (cGMP). This relaxes smooth muscles in blood vessels of the corpus cavernosum, increasing blood flow and thus inducing an erection. The action of Levitra may last up to 6 hours.

Levitra effectively prolongs sexual performance but can be indicated as a remedy to prevent premature ejaculation only along with the treatment of ED.

Levitra is also known as Vardenafilum, Vivanza, Vardif®, Vilitra.

Levitra doesn't protect you or your partner from sexually transmitted diseases (including HIV) or from pregnancy.


Take Levitra orally with a full glass of water 30-60 minutes before sexual intercourse.

Avoid fatty foods as this may affect the effectiveness of the medication.

The effect lasts for 4-6 hours.

The dosage depends on the overall health.

You should take Levitra when it is suitable for you and your partner.

Levitra must not be taken more than once a day.


If you take an overdose of Levitra, you should seek emergency medical attention or contact your healthcare provider immediately.


Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F) and away from excess moisture and heat. Throw away any unused medicine after the expiration date. Keep out of the reach of children.

Phosphodiesterase-5 inhibitors (PDE5I) are an important new class of drugs in the treatment of pulmonary artery hypertension (PHT). Sildenafil, a selective PDE5I, through its action on the NO/cGMP signal pathway, causes a selective reduction of pulmonary vascular resistance and improves symptoms and exercise capacity of patients with PHT. The phase III trial (SUPER-1) has clearly shown the efficacy and safety of sildenafil in PHT so that its use for this indication has recently been approved. Current guidelines of several large specialist societies have included sildenafil for the treatment of PHT, supported by a high degree of evidence. Sildenafil can also be combined with other drugs and has the potential of being efficacious also in other forms of pulmonary hypertension.

There are three phosphodiesterase type 5 (PDE5) inhibitors marketed, sildenafil, Vardenafil, and tadalafil for oral treatment of erectile dysfunction (ED). Although the treatment is simple and mostly effective, around 50% has ceased to use the medication within 2 years. One recently described way to improve the compliance is to let the patient try all the three PDE5 inhibitors and to prescribe the drug(s) he and his partner desires.

Sprague-Dawley rats with monocrotaline-induced PAH were administered oral vardenafil 1 mg kg⁻¹ day⁻¹ for 21 days (n = 12). Treatment-naive patients (n = 15) with PAH were treated with vardenafil 5 mg twice daily for 3 months. Haemodynamic data and plasma levels of nitrate/nitrite and products of oxidative damage were determined in rats and patients. Histopathology, immunohistochemistry, and assessments of oxidative/anti-oxidative enzyme expression were performed in rat lung tissue. Compared with baseline (patients) or untreated controls (rats), vardenafil significantly reduced pulmonary vascular resistance and increased cardiac output (CO). In rats, vardenafil suppressed proliferation and enhanced apoptosis of pulmonary artery smooth muscle cells, attenuating small pulmonary artery remodelling, and right ventricular hypertrophy. Vardenafil significantly reduced levels of oxidative stress biomarkers, such as 8-iso-prostaglandin-F2α and 3-nitrotyrosine, and significantly increased nitric oxide (NO) levels in rats and patients. Furthermore, vardenafil significantly increased endothelial NO synthase expression and superoxide dismutase activity, and down-regulated nicotinamide adenine dinucleotide phosphate oxidase expression in rat lung tissue.

Sildenafil, a phosphodiesterase 5 (PDE5) inhibitor, has become a first-line therapy for diabetic patients with erectile dysfunction (ED). The efficacy in this subgroup, based on the Global Efficacy Question, is 56% vs 84% in a selected group of non-diabetic men with ED. Two novel PDE5 inhibitors, tadalafil (Lilly ICOS) and vardenafil (Bayer), have recently completed efficacy and safety clinical trials in 'general' and diabetic study populations and are now candidates for US FDA approval. A summary analysis of the phase three clinical trials of sildenafil, tadalafil and vardenafil in both study populations is presented to provide a foundation on which the evaluation of the role of the individual PDE5 inhibitors for the treatment of patients with ED and DM can be built.

Decreased production and/or impaired action of nitric oxide (NO) play a role in the pathogenesis of atherosclerotic cardiovascular disease and erectile dysfunction (ED) in diabetic patients. Under hyperglycemic conditions, formation and accumulation of advanced glycation end products (AGE) have been known to progress, thus contributing to tissue damage in diabetes. However, effects of inhibitors of phosphodiesterase-5 (PDE-5), an enzyme that catalyzes the degradation of cyclic guanosin-monophosphate (cGMP) and subsequently blocks the actions of NO, on AGE-exposed endothelial cells remain unknown. Therefore, this study investigated whether and how vardenafil, an inhibitor of PDE-5, could block the deleterious effects of AGE on human umbilical vein endothelial cells (HUVEC). Gene and protein expression was analyzed in quantitative real-time reverse transcription polymerase chain reaction (RT-PCR) and western blots, respectively. Intracellular formation of reactive oxygen species (ROS) was evaluated with dihydroethidium staining. AGE increased receptor for AGE (RAGE) mRNA and protein levels in HUVEC, both of which were significantly inhibited by the treatments with 30 nM vardenafil or 5 μM 8- buy levitra online Br-cGMP, an analogue of cGMP. Further, vardenafil reduced the AGE-induced ROS generation and subsequently inhibited up-regulation of monocyte chemoattractant protein-1 (MCP-1) mRNA levels in HUVEC. We demonstrated here for the first time that vardenafil could block the AGE-induced up-regulation of MCP-1 mRNA levels in HUVEC by suppressing RAGE expression and subsequent ROS generation via elevation of cGMP. Our present results suggest that vardenafil directly acts on endothelial cells and it could work as an anti-inflammatory agent against AGE.

Erectile dysfunction (ED) is a common medical condition that affects the sexual life of millions of men worldwide. Many drugs are now buy levitra online available for the treatment of ED, with oral pharmacotherapy representing the first-line option for most patients. Sildenafil citrate, an inhibitor of the enzyme phosphodiesterase type 5 (PDE5), is the most widely prescribed oral agent and has a very satisfactory efficacy-safety profile in all patient categories. Tadalafil (Cialis; Eli Lilly & Co., ICOS) and vardenafil (Levitra; Bayer Pharmaceuticals, GlaxoSmithKline) are new PDE5 inhibitors that have recently been approved worldwide. Both have been associated with significant positive efficacy-safety profiles. Apomorphine sublingual is a dopamine D1 and D2 receptor agonist, which has been approved for marketing in Europe. It is best selected for treating patients with mild-to-moderate ED, but it is seldom used in clinical practice due to its limited efficacy and side effects, particularly nausea. Patients who do not respond to oral pharmacotherapy or who are unable to use it are appropriate candidates for intracavernosal and intraurethral therapy. The efficacy of second-line treatment is high, but the attrition rate remains significant. For the purpose of this review, clinical and pharmacological analysis focuses on the recent advances in the field of oral therapy, including PDE5 inhibitors and sublingual apomorphine.

We investigated safety and efficacy of vardenafil and sertraline in premature ejaculation (PE). Seventy-two men graded their primary PE on a scale of 0-8 (0 = almost never, 8 = almost always). Intravaginal ejaculatory latency time (IELT) was measured. Patients were included if they scored their PE as 4 or greater and their IELTs were less than 1.30 min. After 6 weeks of behavioural psychosexual therapy, 49 patients still had a PE of 4 or greater and an IELT less than 1.30 min and they were randomised: 6 weeks vardenafil (10 mg) or sertraline (50 mg). After a wash-out phase for 1 week, medication was changed in a cross-over design. Initially, buy levitra online all 72 men with PE received behavioural therapy. Twenty-three men were satisfied with treatment and excluded. The remaining 49 men graded their PE as 5.94 +/- 1.6 and IELT was 0.59 min and patients were randomised. Four men discontinued the study. Vardenafil improved PE grading: 2.7 +/- 2.1 (P < 0.01) and IELT increased to 5.01 +/- 3.69 (P < 0.001). PE grading improved 1.92 +/- 1.32, (P < 0.01) and IELT 3.12 +/- 1.89 (P < 0.001) with sertraline. It is concluded that vardenafil and sertraline are useful agents in the pharmacological treatment of PE.

This randomised, double-blind study assessed the long-term efficacy and tolerability of vardenafil 10 and 20 mg in men with erectile dysfunction (ED). A total of 566 men who completed an initial 12-month treatment period entered a 12-month extension. In these men, both doses of vardenafil produced improvement in scores for the 'erectile function' Domain of the International Index of Erectile buy levitra online Function, evident from week 4 and maintained through 2 years. Sexual Encounter Profile diary responses indicated that following treatment, penetration was achieved on 92-94% of attempts and erections that lasted long enough for successful intercourse were achieved on 87-89% of attempts. In response to the General Assessment Question, 90-92% of patients reported improved erections with vardenafil. Most treatment-emergent events were mild and transient with no cardiovascular safety concerns. These results support the long-term efficacy, reliability and tolerability of vardenafil 10 and 20 mg in men with ED.

Presumably, the vasorelaxant properties of phosphodiesterase type 5 (PDE5) inhibitors are similar in isolated blood vessels. We aimed to explore the mechanisms underlying the vasorelaxation induced by the selective PDE5 inhibitors sildenafil, vardenafil, and tadalafil in the rat aorta. Aortic rings were mounted in 5-ml organ baths, and concentration-response curves for PDE5 inhibitors (0.0001-10 microM) were constructed in phenylephrine (PE)-precontracted endothelium-intact and -denuded rings. Cyclic nucleotides were measured using enzyme immunoassay kits. Sildenafil, vardenafil, and tadalafil concentration dependently relaxed aortic rings and increased cGMP, but not cAMP, concentrations. Endothelium denudation caused marked rightward shifts in the curves to sildenafil (45 Uroxatral Similar Drugs -fold), tadalafil (21-fold), and vardenafil (251-fold). Maximal responses to sildenafil and tadalafil were substantially reduced (38 +/- 1% and 53 +/- 2%, respectively), whereas that evoked by vardenafil was not affected. Likewise, inhibition of NO synthase (N(omega)-nitro-L-arginine methyl ester, 100 microM), guanylyl cyclase (1H-[1,2,4]oxadiazolo [4,3,-a]quinoxalin-1-one, 10 microM), or scavenging of NO ([carboxy-PTIO (2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide), 100 microM]) caused similar attenuation of the vasorelaxations evoked by PDE5 inhibitors. Sildenafil, tadalafil, and vardenafil significantly potentiated relaxations mediated by glyceryl trinitrate (0.0001-3 microM; 8-13-fold) and atrial natriuretic peptide (0.1-100 nM; 2-3-fold). Contractions evoked by CaCl(2) (0.01-5 mM) in PE-treated rings were significantly reduced (26 +/- 4%) by vardenafil, but not sildenafil or tadalafil, whereas phorbol 12,13-dibutyrate-induced contractions were not affected. Ouabain, cyclopiazonic acid, and calyculin A failed to affect vasorelaxations induced by the PDE5 inhibitors. These results suggest that vardenafil, but not sildenafil or tadalafil, affects Ca(2+) handling in the rat aorta in addition to increasing cGMP levels through inhibition of PDE5 to cause relaxation.

The selective SRI, paroxetine (5 mg/kg), significantly inhibited GVR in female rabbits (54 +/- 5% and 48 +/- 6% of control). GVR were also significantly inhibited by the SNRIs, venlafaxine (5 mg/ Indocin Dosage kg) (57 +/- 3% and 32 +/- 11%) and duloxetine (1 mg/kg) (40 +/- 7% and 28 +/- 5%). Treatment with vardenafil (0.1 and 0.3 mg/kg) completely reversed the inhibition of GVR induced by paroxetine, venlafaxine, or duloxetine.

In two randomized, double-blind studies, men with ED for > 6 months received vardenafil 5 mg, 10 mg, or 20 mg or placebo for 12-26 weeks. Patients were instructed to start sexual activity 1 hour after dosing. In this retrospective pooled analysis, patient diary questions through week 12 were analyzed, providing attempt data was recorded 0-12 hours post-dose. Mean per-patient SEP2 and SEP3 success rates (intent-to-treat population) were calculated by time between dosing and start of sexual activity, from 0-12 hours through week 12. Least-square means and nominal p-values for differences versus placebo were derived by analysis of covariance with terms for baseline, study and treatment.

Twenty-four New Zealand rabbits were randomly divided into three groups: sham-operated animals (group A; right-sided operations comprised subgroup A1 and left-sided operations comprised subgroup A2), operated animals (group B) and operated animals that received vardenafil (group C). The right-sided junctions of group A (A1) were not exposed, and therefore made up the control group. The UPJO model was established by partial obstruction of the left junction. Intravenous pyelograms were performed before and after the operation. HE staining and microscopic examinations were performed to chart the pathological changes. Immunohistochemistry (streptavidin peroxidase) was used to test the expression of TGF-beta1 and nNOS in the junctions. RT-PCR detected mRNA expression of TGF-beta1.

This analysis used data from a previously published 12-week, prospective, randomized, double-blind, flexible-dose, placebo-controlled study conducted at 41 hospitals and outpatient clinics across Australia, Europe, Asia, and North America. In that study, men with ED and sildenafil nonresponse, defined using 6 rigorous criteria (including nonresponse to the highest recommended dose, 100 mg/d) were assigned to receive vardenafil 10 mg or placebo QD. At study weeks 4 and 8, patients in both groups were given the option to maintain the 10-mg/d dose, or have the dose titrated to 5 or 20 mg/d. The present analysis used data from patient diaries completed daily, which included information concerning attempts at sexual intercourse, time from dosing to attempt, penetration, and maintenance of erection sufficient for successful intercourse. At week 12, diary data were categorized into time intervals (in hours) after dosing. For each interval, the per-patient success rate was based on the total number of attempts made in that interval. Comparative statistics were not performed on the time-interval analysis. Tolerability was monitored throughout the study. Data concerning the primary end point were reported previously.
