Vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor, was evaluated in a prospective trial in the primary care setting involving hypertensive men with ED who were receiving at least one antihypertensive medication.
To investigate the safety and efficacy of flexible-dose vardenafil therapy compared with placebo in PDE5 inhibitor-naïve subjects with arterial hypertension and ED.
In this multicenter, randomized, double-blind, placebo-controlled study, 354 patients received placebo or vardenafil (5-20 mg) for 12 weeks. Primary efficacy measures were diary responses to the Sexual Encounter Profile (SEP) questions 2 (vaginal insertion) and 3 (maintenance of erection). Additional efficacy measures included positive responses to the Global Assessment Question (GAQ).
Compared with placebo, vardenafil significantly improved mean SEP2 and SEP3 success rates over the 12-week study period (intention-to-treat [ITT] and last observation carried forward [LOCF]) analysis). For LOCF, SEP2 and SEP3 were 83% for vardenafil vs. 58% for placebo and 67% for vardenafil vs. 35% for placebo, respectively (P<0.0001 vs. placebo). Improved erections (GAQ) were experienced by 80% of vardenafil-treated patients at study end, compared with 40% for placebo (P<0.0001, LOCF). The most commonly reported treatment-emerging adverse events were headache (3.1%) and flushing (1.6%), which were mild-to-moderate and transient in nature. Importantly, there were no significant changes in systolic and diastolic blood pressure or heart rate between the vardenafil and placebo groups. The average number of antihypertensives used per patient was 1.5 and 1.4 in the vardenafil and placebo groups, respectively. Both the incidence of adverse events and the ability to maintain an erection were unaffected by stratification into distinct subsets according to the class of antihypertensive medication being received.
Vardenafil significantly improves EF in hypertensive men treated with concomitant antihypertensive medication, is well tolerated, and does not significantly affect blood pressure.

- "The findings from many epidemiological studies show that ED is associated with chronic diseases such as diabetes mellitus (DM), hypertension, and spinal cord injury . Several studies have shown that PDE5 inhibitors improve ED in males with chronic diseases [27,28,29,30]. However, few studies have been conducted on mirodenafil in this regard despite the general presumption that mirodenafil is also effective for ED in subjects with chronic diseases. "

ABSTRACT: Phosphodiesterase type 5 (PDE5) inhibitors are the most commonly used treatment for erectile dysfunction (ED). Since the launch of sildenafil, several drugs-including mirodenafil, sildenafil citrate (sildenafil), tadalafil, vardenafil HCL (vardenafil), udenafil, and avanafil-have become available. Mirodenafil is a newly developed pyrrolopyrimidinone compound, which is a potent, reversible, and selective oral PDE5 inhibitor. Mirodenafil was launched in Korea in 2007, and an orally disintegrating film of mirodenafil was developed in 2011 for benefitting patients having difficulty in swallowing tablets. This study aimed to review the pharmacokinetic characteristic profile of mirodenafil and report evidence on its efficacy in the case of ED. In addition, we reviewed randomized controlled studies of mirodenafil's daily administration and efficacy for lower urinary tract symptoms.

- "Accordingly, given the close association between ED and hypertension, the need to determine the efficacy and safety of PDE-5 inhibitors for ED therapy in this patient group has assumed greater importance. A 12-week, multicenter, randomized, double-blind, placebo-controlled trial conducted in Germany investigated the efficacy of flexible-dose vardenafil in men with ED and arterial hypertension, which was adequately controlled with at least one antihypertensive medication.64 Compared with placebo, vardenafil significantly improved SEP2 and SEP3 success rates over the study period (P < 0.0001).

ABSTRACT: Many men with erectile dysfunction (ED) also have associated underlying cardiovascular and metabolic conditions, for which they are likely to be taking medication. Therefore, cardiovascular safety and potential drug interactions are two of the major concerns when using PDE-5 inhibitors in these patients. The PDE-5 inhibitor, vardenafil, is characterized by a rapid onset of action, increased duration of erection, high rates of first-dose success and reliable efficacy that can be maintained with continued use. In both clinical trials and real-life observational studies, vardenafil has demonstrated a favorable efficacy and safety profile in men with ED, including those with associated underlying conditions such as diabetes, hypertension and dyslipidemia. Importantly, the concomitant use of medication for these conditions is not associated with any noteworthy changes in the efficacy and safety of vardenafil. The evidence presented in this review supports the use of vardenafil as a first-line treatment for men with ED, including those with underlying conditions.

- "In a randomised, doubleblind , placebo-controlled study with 395 participants , aged 18–64 years with ED for >6 months, vardenafil was clearly superior over placebo with regard to scores of vaginal penetration and completion of intercourse . A great range of studies attest to the safety of vardenafil     . In conclusion: the efficacy and safety of vardenafil have now been demonstrated in numerous studies worldwide in men with ED and underlying cardiovascular conditions. "

ABSTRACT: The introduction in 1998 of the phosphodiesterase type 5 (PDE-5) inhibitors has changed the landscape of diagnosis and, in particular, the treatment of erectile dysfunction (ED). It has paved the road for a more profound insight into ED. ED and other ailments of elderly men, such as atherosclerosis, hypertension, diabetes mellitus and lower urinary tract symptoms were usually regarded as distinct diagnostic/therapeutic entities, but there is growing evidence that they are interrelated and are factors in ED. To optimise the treatment of ED, an integral approach to the health of the ageing male is required. There is an interdependence between the metabolic syndrome, ED and patterns of testosterone in ageing men. The main features of the metabolic syndrome are abdominal obesity, insulin resistance, hypertension and dyslipidaemia, significant factors in the aetiology of erectile function. The metabolic syndrome is associated with lower-than-normal testosterone levels. Testosterone is a determinant of glucose homeostasis and lipid metabolism. Testosterone is not only a factor in libido but also exerts essential effects on the anatomical and physiological substrate of penile erection. With these recent insights, the health problems of elderly men must be placed in a context that allows an integral approach. While PDE-5 inhibitors are the mainstay of treatment of men with ED, treatment of testosterone deficiency is becoming part and parcel of a new approach to both ED and the metabolic syndrome. The diagnostic work-up of ED should comprise measurement of plasma testosterone. If proven deficient, treatment with testosterone is indicated.
