Clinical Trials Related to Revatio (Sildenafil)

A Multicenter, Double-Blind Study to Evaluate the Effect of Pretreatment With a Daily Dose of Sildenafil on the As-Needed Efficacy of Viagra in Men With Erectile Dysfunction and Type 2 Diabetes [Completed]
To determine the effect on erectile function in a population of type 2 diabetic men with erectile dysfunction who have undergone the following treatment regimen: pre-treatment with a daily dose of double-blind sildenafil versus placebo for 4 weeks (Phase I) followed by an as-needed, flexible-dose, open-label treatment phase with sildenafil for 12 weeks (Phase II). To assess safety and tolerability of this dosing regimen and to investigate its effects on endothelial function and subject's responses to the Self-Esteem And Relationship (SEAR) questionnaire.

A Placebo-Controlled Single-Dose Trial of Sildenafil in Schizophrenia [Completed]
The study is a double-blind, placebo-controlled, random-order, single-dose crossover trial of sildenafil 50 & 100 mg added to stable antipsychotic treatment in schizophrenia patients to assess whether this PDE5 inhibitor improves cognitive functioning (including verbal memory, fluency, attention, spatial memory, motor speed, and executive function) and clinical symptoms (psychotic, negative, mood symptoms, and self-reports of side-effects).

Sildenafil (Viagra) Treatment of Subacute Ischemic Stroke [Recruiting]
Stroke is the third leading cause of death in the United States and the leading cause of serious long-term disability. Approximately 50% of the 750,000 people affected by stroke each year have residual physical impairment. Treatment options for recovery are limited at this time. Sildenafil (Viagra) has demonstrated the capability of significantly improving recovery in several animal experiments of stroke. This study is aiming to establish the safety of treatment with sildenafil in people with stroke with the ultimate aim of testing its usefulness to improve recovery.

Revatio for Heart Disease in Duchenne Muscular Dystrophy and Becker Muscular Dystrophy [Recruiting]
This study, supported by Charley's Fund, Inc., is being done to determine if the drug RevatioŽ(also known as Sildenafil), as compared to placebo (an inactive substance that looks like the study drug, but contains no medication), improves heart function in people with Duchenne Muscular Dystrophy and Becker Muscular Dystrophy (DBMD).

In people with DBMD, dystrophin is not present or lacking in heart and muscle. This is associated with abnormalities in an enzyme called "neuronal nitric oxide synthase" or nNOS, and leads to decreases in "cyclic GMP," which is necessary for proper function of those muscles. Revatio blocks an enzyme called phosphodiesterase 5 (PDE5), and helps to restore the normal amounts of cyclic GMP. The purpose of this research is to determine if Revatio is safe for people with DBMD and if it can improve heart function.

Hypothesis : PDE5 inhibition, with the use of Revatio, will improve cardiac function in patients with DBMD.

Effect of Tadalafil on Exercise Capacity in Pediatric Fontan Patients [Recruiting]
This pilot study is aimed at assessing the short-term effects of Tadalafil on the hemodynamic response to exercise and exercise capacity in patients with Fontan circulation. Data regarding effect size and drug tolerability will be used in the design of a randomized multicenter trial. The long-term goal of this investigation is to systematically evaluate the effect of tadalafil therapy on exercise performance, quality of life, and delay of functional deterioration in patients with single ventricle physiology.
