Description

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.

Dosage

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.

Overdose

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

In nine European countries at 904 sites, 8047 patients were enrolled and 94% (7560) selected either tadalafil (5315), sildenafil (1252), or vardenafil (993) for treatment at baseline. Of the 7560, 3998 (52.9%) took the same drug for 6 mo. Baseline characteristics across the three treatment groups were comparable: mean age approximately 56 yr, moderate or severe ED, and mean International Index of Erectile Function-Erectile Function domain score about 13. Tadalafil, sildenafil, and vardenafil were therapeutically effective and improved patient satisfaction in the 40-58% of men who completed 6 mo of a single therapy. Patients taking tadalafil consistently had numerically higher levels of therapeutic effectiveness and satisfaction compared with patients who took sildenafil or vardenafil. The three cohorts had statistically significant changes from baseline in response to SF-PAIRS and there were significant differences, in favour of tadalafil, among cohorts in the Time Concerns domain.

The therapeutic effects of phosphodiesterase type 5 inhibitors in patients with pulmonary arterial hypertension (PAH) were reviewed. A double-blind, placebo-controlled study named SUPER-1 showed that sildenafil improved exercise capacity, WHO functional class, hemodynamics, and quality of life. Two randomized, double-blind, crossover studies, showed that sildenafil improved exercise tolerance and quality of life, and reduced estimated pulmonary artery systolic pressure. The dose independent effects of sildenafil on PAH are controversial. There are few case-reports that show vardenafil and tadalafil have benefits in PAH patients. A double-blind study of tadalafil in PAH patients is ongoing.

Several studies assessed the role of the nitric oxide/cGMP signalling pathway in the regulation of the prostate tone, with the support of clinical observations. PDE5-Is can also represent a potential mode of action allowing the targeting of transcriptional activity implicated in the regulation of the progression of the inflammatory process involved in BPH. PDE5-Is can inhibit human stromal cell proliferation of the prostate mediated by cGMP accumulation. New targeting hypotheses of pathophysiological processes are also reported.

Vardenafil administration improved erectile functionality in controlled type 2 diabetes mellitus patients with ED, which was associated with reduction of circulating plasma β-tropomyosin levels. Tropomyosin affected by itself the cGMP generating system suggesting a possible new mechanism involved in ED. Vardenafil reversed the reduction effect of cGMP content elicited by tropomyosin in BAECs.

Bilateral CN crush injury followed by a 3-wk recovery period decreased erectile responses to ES CN by about 50%. In CN-crushed rats, IV vardenafil 0.03 mg/kg and BAY 60-4552 (0.03 or 0.3 mg/kg) increased erectile responses to ES CN to the same extent: Δ intracavernosal pressure/mean arterial pressure (ICP/MAP) at 10 Hz ES CN was 21±1% after vehicle, 25±3% (p<0.001) after vardenafil, and 26±5% and 27±5% after BAY 60-4552 0.03 mg/kg (p<0.01) and 0.3 mg/kg (p<0.001), respectively. The combination of vardenafil with BAY 60-4552 in CN-crushed rats totally restored erectile responses to ES CN equivalent to sham rats (ΔICP/MAP at 10 Hz ES CN: 34±4% after BAY 60-4552/vardenafil combination vs 39±4% in sham rats; not significant).

The efficiency of treatment with phosphodiesterase-5 (PDE-5) inhibitors in combination with antibacterial drugs in chronic bacterial prostatitis (CBP) was studied in a randomized trial with participation of 103 CBP patients (mean age 36.2 +/- 8.4 years). Group 1 patients (n = 32) received levofloxacine (500 mg/day) monotherapy for 4 weeks. Group 2 patients (n = 34) received antibacterial treatment plus wardenafil in a dose 10 mg in the evening. Group 3 patients (n = 37) received combined treatment (fluoroquinolone + wardenafil), PDE-5 inhibitor was taken for more than 2 times a week 10-60 min before the coitus. Treatment efficacy was assessed with NIH-CPSI scale, count of bacteria and leukocytes in the pre- and postmassage urine portions, uroflowmetry. By NIH-CPSI scale, a significant (p < 0.001) improvement was seen in dysuria and quality of life in group 2. The control test discovered pyuria in postmassage urine in 7 (21.9%), 4 (11.8%) and 6 (16.2%) patients of group 1, 2 and 3, respectively. Manifest bacteriuria was registered in 3 (9.4%), 2 (5.9%) and 3 (8.1%) patients, respectively. Uroflowmetry reported significant changes (p < 0.05) in urine volume only in patients of group 2. Efficacy of CBP treatment significantly rises in combination of antibacterial treatment with wardenafil.

A total of 463 men were enrolled, of whom 457 were included in the safety analysis (vardenafil, n = 231; placebo, n = 226) and 454 in the intent-to-treat analysis (vardenafil, n = 229; placebo, n = 225; mean age, 60.1 vs 59.0 years; mean body mass index, 28.7 vs 28.0 kg/m2). Six patients were excluded from the safety analysis (2 patients did not use study medication [placebo group], postbaseline safety data unavailable in 4 patients [2 in each study group]). Men receiving vardenafil had numerically greater penetration and completion success rates compared with those receiving placebo at all time intervals. Penetration success rates were numerically higher with vardenafil compared with placebo as early as within 0.25 hour after dosing (62% vs 30%); efficacy continued beyond 6 hours after dosing in 77% and 50% of patients, respectively. Similarly, vardenafil-treated patients had numerically greater completion success rates compared with those receiving placebo at 0.25 hour (53% vs 12%) and beyond 6 hours after dosing (70% vs 24%). The most common drug-related adverse events in the vardenafil and placebo groups were flushing (7% vs 1%), headache (6% vs 2%), and nasal congestion (5% vs <1%).

Phosphodiesterase type-5 (PDE-5) inhibitors are novel and important options for the treatment of pulmonary arterial hypertension (PAH). Therefore, we aimed to examine effects of vardenafil, a PDE-5 inhibitor, on the pulmonary arteries isolated from rats with monocrotaline- (MCT-) induced pulmonary hypertension. MCT (60 mg/kg) or its vehicle was administered by a single intraperitoneal injection to 6-week-old male Sprague Dawley rats. Rats were sacrificed 21 days after MCT injection, and the main pulmonary arteries were isolated and then mounted in 20 mL organ baths. Concentration-response curves for vardenafil (10(-10)-10(-5) M) were constructed in phenylephrine- (Phe-) precontracted rings. PAH caused marked rightward shift in the curves to vardenafil whereas maximal responses were not affected. Inhibition of NO synthase (L-NAME, 10(-4) M) or guanylyl cyclase (ODQ, 10(-5) M) caused similar attenuation in responses evoked by vardenafil. Moreover, contraction responses induced by CaCl(2) (3 × 10(-5)-3 × 10(-2) M) were significantly reduced in concentration-dependent manner by vardenafil. In conclusion, vardenafil induced pulmonary vasodilatation via inhibition of extracellular calcium entry in addition to NO-cGMP pathway activation. These results provide evidence that impaired arterial relaxation in PAH can be prevented by vardenafil. Thus, vardenafil represents a valuable therapeutic approach in PAH besides other PDE-5 inhibitors.

Vardenafil is an oral, potent, highly selective phosphodiesterase 5 (PDE5) inhibitor. It improves erectile function significantly regardless of the etiology and severity of erectile dysfunction (ED) or the age of the patients. Its onset time leading to successful intercourse is as short as 10 minutes after administered orally, and in most patients it works persistently. Adverse reactions are generally transient and mild to moderate in nature. So vardenafil is both effective and safe for men with ED.

Pulmonary arterial hypertension (PAH) is a rare disease characterized by vascular proliferation and remodeling, resulting in a progressive increase in pulmonary arterial resistance, right heart failure, and death. The pathogenesis of PAH is multifactorial, with endothelial cell dysfunction playing an integral role. This endothelial dysfunction is characterized by an overproduction of vasoconstrictors and proliferative factors, such as endothelin-1, and a reduction of vasodilators and antiproliferative factors, such prostacyclin and nitric oxide. Phosphodiesterase type 5 (PDE-5) is implicated in this process by inactivating cyclic guanosine monophosphate, the nitric oxide buy levitra pathway second messenger. PDE-5 is abundantly expressed in lung tissue, and appears to be upregulated in PAH. Three oral PDE-5 inhibitors are available (sildenafil, tadalafil, and vardenafil) and are the recommended first-line treatment for erectile dysfunction. Experimental studies have shown the beneficial effects of PDE-5 inhibitors on pulmonary vascular remodeling and vasodilatation, justifying their investigation in PAH. Randomized clinical trials in monotherapy or combination therapy have been conducted in PAH with sildenafil and tadalafil, which are therefore currently the approved PDE-5 inhibitors in PAH treatment. Sildenafil and tadalafil significantly improve clinical status, exercise capacity, and hemodynamics of PAH patients. Combination therapy of PDE-5 inhibitors with prostacyclin analogs and endothelin receptor antagonists may be helpful in the management of PAH although further studies are needed in this area. The third PDE-5 inhibitor, vardenafil, is currently being investigated in PAH. Side effects are usually mild and transient and include headache, flushing, nasal congestion, digestive disorders, and myalgia. Mild and moderate renal or hepatic failure does not significantly affect the metabolism of PDE-5 inhibitors, whereas coadministration of bosentan decreases sildenafil and tadalafil plasma levels. Due to their clinical effectiveness, tolerance profile, and their oral administration, sildenafil and tadalafil are two of the recommended first-line therapies for PAH patients in World Health Organization functional classes II or III.

Erectile dysfunction (ED) is a major complication after radical prostatectomy (RP); however, debate continues regarding the efficacy of penile rehabilitation in the recovery of the postoperative erectile function (EF). This study included a total of 103 consecutive sexually active Japanese men with localized prostate cancer undergoing nerve-sparing RP, and analyzed the postoperative EF, focusing on the significance of penile rehabilitation. In this series, 24 and 79 patients underwent bilateral and unilateral nerve-sparing RPs, respectively, and 10 or 20 mg buy levitra of vardenafil was administered to 35 patients at least once weekly, who agreed to undergo penile rehabilitation. Twelve months after RP, 48 (46.6%) of the 103 patients were judged to have recovered EF sufficient for sexual intercourse without any assistance. The proportion of patients who recovered EF in those undergoing penile rehabilitation (60.0%) was significantly greater than that in those without penile rehabilitation (38.2%). Of several parameters examined, the preoperative International Index of Erectile Function-5 (IIEF-5) score and nerve-sparing procedure were significantly associated with the postoperative EF recovery rates in patients with and without management by penile rehabilitation, respectively. Furthermore, univariate analysis identified the preoperative IIEF-5 score, nerve-sparing procedure and penile rehabilitation as significant predictors of EF recovery, among which the preoperative IIEF-5 score and nerve-sparing procedure appeared to be independently associated with EF recovery. Considering these findings, despite the lack of independent significance, penile rehabilitation with low-dose vardenafil could exert a beneficial effect on EF recovery in Japanese men following nerve-sparing RP.

Erectile function is determined by tight regulation of relaxation or contraction of corpus cavernosal smooth muscle, which is the result of a long and complex chain of molecular events. Control of erectile function resides in signaling pathways of the central and peripheral nervous system, as well as intracellular events in the penile smooth muscle. Vascular events resulting in erection have long been understood, and the role of the signaling pathways of the central and peripheral nervous systems in erectile buy levitra function and dysfunction has become increasingly clear over the last decade. This knowledge has led to the development and current availability of effective oral treatments for erectile dysfunction, the selective phosphodiesterase type 5 (PDE5) inhibitors-sildenafil, vardenafil and tadalafil. In the past few years we have seen an elucidation of the molecular events involved in erectile function and dysfunction and the detailed mechanisms of action by which the specific PDE5 inhibitors work. A review of those mechanisms helps to explain the success of the currently available PDE5 inhibitors and the differences between them and suggests new approaches for developing potential future novel therapies or refinements to existing structures that may improve their efficacy, selectivity and safety profiles.

Drug interactions due to efflux transporters may result in one drug increasing or decreasing the systemic exposure of a second drug. The potential for in vivo drug interactions is estimated through in vitro cell assays. Variability in in vitro parameter determination (e.g., IC₅₀ values) among laboratories may lead to different conclusions in in vivo interaction predictions. The objective of this study was to investigate variability in in vitro inhibition potency determination that may be due to calculation methods. In a Caco-2 cell assay, the absorptive and secretive permeability of digoxin was measured in the presence of spironolactone, itraconazole and vardenafil. From the permeability data, the efflux ratio and net secretory flux where calculated for each inhibitor. IC₅₀ values were then calculated using a variety of equations and software programs. All three drugs decreased the secretory transport of digoxin in a concentration-dependent manner while increasing digoxin's absorption to a lesser extent. The resulting IC₅₀ values varied according to the parameter evaluated, whether percent inhibition or percent control was applied, and the computational IC₅₀ equation. This study has shown that multiple methods used to quantitate the inhibition of drug efflux in a cell assay can result in different IC₅₀ values. The variability in the results in this study points to a need to standardize any transporter assay and calculation methods within a laboratory and to validate the assay with a set of known inhibitors and non-inhibitors against a buy levitra clinically relevant substrate.

The aim of the present study was to investigate the mechanisms underlying the vasorelaxation induced by the selective phosphodiesterase 5 (PDE5) inhibitor vardenafil in rat penile small arteries. Segments of the rat dorsal penile artery were mounted in microvascular myographs for isometric tension recording. Concentration-response curves for vardenafil (1 nM-3 microM) and other PDE inhibitors (sildenafil, rolipram and milrinone) were constructed by adding cummulative concentrations of the drugs to arteries precontracted with phenylephrine. The effect of mechanical endothelial cell removal and of selective blockers of the nitric oxide (NO)/cGMP pathway and K+ channels were evaluated on the vardenafil relaxant responses. Vardenafil was the most potent of the four PDE inhibitors tested that maximally relaxed penile arteries, pD2 and maximum relaxation being 6.96+/-0.08 and 97+/-1% (n=48), respectively. Blockade of guanylate cyclase with ODQ (5 microM), mechanical removal of the endothelium or inhibition of NO synthase with l-NOARG (100 microM) markedly reduced vardenafil-induced relaxations, without altering maximum response. Inhibitors of both the cGMP-dependent (PKG) and the cAMP-dependent (PKA) protein kinases, Rp-8-Br-PET-cGMPS (5 microM) and Rp-8-CPT-cAMPS (50 microM), respectively, both reduced vardenafil relaxant responses and the later abolished that of rolipram. Vardenafil-elicited relaxation was reduced by the selective inhibitor of the large-conductance Ca2+-activated K+ channels (BK(Ca)), iberiotoxin (30 nM) and also by the ATP-sensitive K+ channel (K(ATP)) inhibitor, glibenclamide (1 microM). Vardenafil induces a potent vasodilatation in rat penile arteries that is partially dependent on the endothelium and the NO/cGMP pathway and involves activation of both BK(Ca) and K(ATP) channels.
