To evaluate the safety and pharmacodynamic effect of co-administration of subtherapeutic doses of PT-141, a cyclic heptapeptide melanocortin analogue, and sildenafil to patients with erectile dysfunction.
The intent-to-treat population included 343 couples, with 168 and 175 men receiving vardenafil or placebo, respectively. Vardenafil treatment significantly improved both erection maintenance and the female partners' sexual quality of life. Least squares (LS) mean SEP3 overall success rates after 12 weeks of treatment were 9.5 (baseline) vs. 67.2 (week 12) and 12.4 (baseline) vs. 24.2 (week 12) in the vardenafil and placebo groups, respectively (P < 0.0001). In female partners, LS mean mSLQQ-QOL scores were 28.8 (baseline) vs. 68.2 (last observation carried forward [LOCF]) in the vardenafil group and 24.6 (baseline) vs. 40.5 (LOCF) in the placebo group (P < 0.0001).

At 60 min a reduction in mPAP with a median % decrease of -20.3% (range -48.3 to 3.0; P < 0.001) and an increase in cardiac output and the cardiac index with a median % change of 10.6% (range -25.0 to 88.1; P = 0.015) and 12.1% (range -24.0 to 94.4; P = 0.01) respectively was observed. The pulmonary vascular resistance (PVR) was reduced with a median % decrease of -28.9% (range -61.5 to -5.9; P < 0.001), and pulmonary selectivity was reflected by a median percent reduction of -16.9% (range -49.0 to 16.5; P = 0.002; n = 14) in the PVR/systemic vascular resistance ratio. There was a correlation between the plasma concentrations of vardenafil and change in mPAP (r = -0.579, P = 0.019) and between vardenafil concentrations and change in PVR (r = -0.662, P = 0.005).
The meta-analysis of the available cross-sectional data suggests that PDE5-Is can significantly improve LUTS and erectile function in men with BPH. PDE5-Is seem to be a promising treatment option for patients with LUTS secondary to BPH with or without ED.
Main factors influencing the choice of the treatment for ED have been described. A short list of items that may help in choosing the right PDE5 inhibitor for the treatment of different patients in daily clinical practice has been prepared.

Inhibiting cyclic guanosine monophosphate metabolism may induce penile erection during concomitant nitric oxide production. Vardenafil hydrochloride is a new, highly selective, potent cyclic guanosine monophosphate phosphodiesterase 5 inhibitor. We determined the oral effectiveness of vardenafil in a simple and quantitative conscious rabbit model.

We present a review of the literature and 2 cases of CSC in 2 men taking PDE5 inhibitors (vardenafil and tadalafil) for erectile dysfunction. In both cases chorioretinopathy appeared after intake of the inhibitor, resolved once the latter was discontinued, reappeared when the inhibitor was restarted and resolved once again after the inhibitor had been discontinued for the second time.

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.
A new herbal health product marketed for enhancing erectile function, namely Power58 Platinum, was purchased over-the-counter in Hong Kong. The product was tested for adulteration with sildenafil, tadalafil, and vardenafil as well as their structurally modified analogues. A new analogue of vardenafil, in which the N-ethylpiperazine ring and the sulphonyl group were removed from the vardenafil structure, was identified in the product.

This was an open-label, multicenter, flexible dose, 12-week study in patients with ED due to SCI. Following a 4-week observation period, patients received vardenafil 10 mg for 4 weeks, and based on efficacy, tolerability and patient preference, doses for the remaining 8 weeks were decided by investigators. The primary efficacy parameter was erectile function domain score of the International Index of Erectile Function.

Vardenafil administration achieved increased peak flow velocity comparable to that after intracavernous papaverine injection. With no prolonged erection vardenafil is a safer alternative compared to more invasive intracavernous injection and is also an alternative for patients who fear injections.

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.
