Active clinical trials for "Erectile Dysfunction"

The purpose of this study is to demonstrate the usability of the system.

The purpose of this study is to perform a relative bioavailability study between two formulations of sildenafil citrate.

The aim of this prospective, non-interventional post-marketing surveillance study is to obtain data on safety and efficacy of Levitra in routine treatment of erectile dysfunction. Furthermore, the data collection particularly focuses on the experience of the patient and his satisfaction with the treatment. Treatment naive patients as well as pre-treated patients will be included in the study.The maximum observation period per patient is 12 months.Besides the physician's documentation, the patient should fill out a questionnaire at every visit. The questionnaires will be handed out and collected by the physician. Furthermore, an additional questionnaire for the patient's partner can be distributed at each visit in case the partner is willing to participate.

The purpose of this study is to assess functional outcomes post operatively after the use of BioDFence® G3 during robotic radical prostatectomy.

The study will address the role of internal pudendal artery disease in erectile dysfunction (ED), and whether it might eventually be amenable to intervention with stenting. There is currently a small trial investigating the potential benefit of stenting for erectile dysfunction, but the relationship between pelvic arterial stenoses and erectile dysfunction is not yet proven. The investigators intend to perform angiography on patients both with and without erectile dysfunction, to see whether internal pudendal artery disease is more common in the population with erectile dysfunction. In addition to angiography, stenoses will be examined using fractional flow reserve. The degree of internal pudendal artery disease will then be correlated with the degree of erectile dysfunction using a validated questionnaire, the International Index of Erectile Function (IIEF). Patients will then complete IIEF questionnaires for 5 years to assess the relationship between internal pudendal artery disease and progression of erectile dysfunction.

Patients with diabetes are three times more likely to develop erectile dysfunction (ED), and longer duration of diabetes is strongly associated with ED. The possibility of pharmacokinetic interactions may occur as the two drugs are metabolized by hepatic CYP3A4 and their co administration may affect their plasma concentrations. the aim of work is to investigate the effect of sildenafil a CYP3A4 substrate and inhibitor on the pharmacokinetics and safety of Saxagliptin, a CYP3A4 substrate Subjects and Methods: Eighteen healthy volunteers will be recruited in Sequential, single center study to determine pharmacokinetic parameters of Saxagliptin, and sildenafil,(AUC0→∞), (AUC0→t); Cmax; tmax; t½, k; ka) will be measured using validated LC-MS/MS method. Therapeutic doses will be given to volunteers as follows: Sildenafil 50 mg single dose on day 1, then washout period from day 2 till day 8. Saxagliptin 5 mg once/day will be given from day 9 till day 12, then on day 13 the two drugs will be co-administered. Blood samples (5ml) for pharmacokinetic analysis will be collected on days 1 and 13 for Sildenafil as well as on days 12 and 13 for Saxagliptin.

We are investigating the chronic effect of daily assumption of Viagra on the blood vessels function in patients with impotence. The study will include 2 groups: 1- patients with multiple risk factors, e.g. hypertension 2- patients with no cardiovascular risk factors

A Prospective, First in Human Study to Evaluate the Safety and Performance of a Flow Modification System

Observational study to evaluate the effect of Tadalafil 5mg once daily on Erectile Dysfunction and QOL in Andropause patients with Erectile Dysfunction. Patients will be observed for 8weeks.

To evaluate the level of NGF,TrKA and p75NTR in patientd with erectile dysfunction and diabetes with or without metabolic syndrome
