Sildenafil, a phosphodiesterase-5 inhibitor sold as Viagra, is a cardioprotector against myocardial ischemia/reperfusion (I/R) injury. Our study explored whether sildenafil protects against I/R-induced damage in a porcine cardiac arrest and resuscitation (CAR) model via modulating the renin-angiotensin system. Male pigs were randomly divided to three groups: Sham group, Saline group, and silden...
INTRODUCTION Sildenafil citrate is a type 5 phosphodiesterase inhibitor, which has demonstrated excellent results in the treatment of erectile dysfunction. The effect of sildenafil citrate in the cavernous arteries of patients with erectile dysfunction has not been established yet. The objective of this study was to assess the effect of sildenafil citrate in the cavernous arteries of patients w...
AIM To assess the efficacy of sildenafil and continuous positive airway pressure (CPAP) in the treatment of concurrent erectile dysfunction (ED) with obstructive sleep apnea (OSA), and to gauge the level of treatment satisfaction in patients and their partners. METHODS Forty men were treated for 12 weeks with sildenafil 100 mg (20 men) or CPAP during nighttime sleep (20 men). Treatment effica...
objective(s) sildenafil citrate is a new drug and has special properties that bring about nitric oxide effects on vascular smooth muscle. the aim of this study was to assess the effects of ovarian stimulation and sildenafil citrate injection on pinopode expression in mice. materials and methods thirty adult female mice were randomly divided into three groups: control, hyperstimulated and hypers...
Pulmonary hypertension frequently complicates the postoperative management of patients after congenital cardiac surgery. Inhaled nitric oxide is an effective treatment option, but rebound pulmonary hypertension can occur upon its withdrawal. Sildenafil may facilitate its withdrawal by restoring cyclic guanosine monophosphate availability via phosphodiesterase-5 inhibition. The purpose of this s...
The phosphodiesterase-5 inhibitor sildenafil is an established and approved drug to treat symptoms of a variety of human diseases. In the context of cystic fibrosis (CF), a genetic disease caused by a defective CFTR gene (e.g. ΔF508-CFTR), it was assumed that sildenafil could be a promising substance to correct impaired protein expression. This study focuses on the molecular mechanisms of silde...
OBJECTIVE This study had 2 goals: (1) to identify clinical and demographic characteristics associated with sildenafil exposure for infants with bronchopulmonary dysplasia (BPD)-associated pulmonary hypertension (PH); and (2) to characterize hospital-specific treatment frequency, age at first administration, and length of sildenafil treatment. METHODS This retrospective cohort study used data ...
BACKGROUND Mitochondrial large-conductance Ca2+-sensitive potassium (mBKCa) channels are involved in myocardial ischemic preconditioning. Their role in sildenafil-induced cardioprotection is unknown. We investigated whether sildenafil-induced acute cardioprotection is mediated by activation of mBKCa channels in the rat heart in vitro. METHODS Male Wistar rats (n = 8 per group) were randomized...
BACKGROUND The prognosis of patients with severe pulmonary hypertension (PHT) is poor. To determine prognosis and guide therapy, an acute hemodynamic trial of selective pulmonary vasodilators, usually inhaled nitric oxide (iNO), was performed. We hypothesized that oral sildenafil, a phosphodiesterase-5 inhibitor, is a safe and effective alternative to iNO. METHODS AND RESULTS We studied 13 co...
چکیده : زمینه و هدف : امروزه در بسیاری از محیط های شغلی نظیر صنایع هسته ای، نظامی و شیمیایی بروز یک خطای انسانی می تواند به حادثه ای فاجعه بار منتهی شود. ویژگی عمومی سیستم های تکنولوژیکی بزرگ این است که مقادیر عظیمی از مواد بالقوه خطرناک در یک واحد متمرکز هستند و توسط چند اپراتور اتاق کنترل، کنترل می شوند. اتاق کنترل به عنوان قلب تپنده یک سیستم می باشد و هر گونه خطا در وظایف اپراتورها می توان...
