Morbi-mortality in cystic fibrosis (CF) is mainly related to chronic lung infection and inflammation, uncontrolled tissue rearrangements and fibrosis, and yet the underlying mechanisms remain largely unknown. We evaluated inflammatory and fibrosis responses to bleomycin in F508del homozygous and wild-type mice, and phenotype of fibroblasts explanted from mouse lungs and skin. The effect of vard...

PURPOSE To investigate the effect of vardenafil in kidney of rats submitted to acute ischemia and reperfusion. METHODS Twenty-eight rats were randomly distributed into two groups. Right nephrectomy was performed and the vardenafil group received vardenafil solution (at a concentration of 1 mg/ml in 10 mg/kg) while the control group received 0.9% saline solution (SS) one hour prior to the liga...

OBJECTIVES The effect of vardenafil, a potent and highly selective phosphodiesterase-5 (PDE5) inhibitor, on symptom-limited exercise time, time to first awareness of angina, and time to ischemic threshold (ST-segment depression > or =1 mm from baseline) during exercise tolerance testing (ETT) was examined in patients with stable coronary artery disease (CAD). BACKGROUND Erectile dysfunction (...

BACKGROUND Chemotherapeutic drugs and newly developed therapeutic monoclonal antibodies are adequately delivered to most solid and systemic tumors. However, drug delivery into primary brain tumors and metastases is impeded by the blood-brain tumor barrier (BTB), significantly limiting drug use in brain cancer treatment. METHODOLOGY/PRINCIPAL FINDINGS We examined the effect of phosphodiesteras...

A valid, sensitive and rapid spectrofluorimetric method has been developed and validated for determination of both tadalafil (TAD) and vardenafil (VAR) either in their pure form, in their tablet dosage forms or spiked in human plasma. This method is based on measurement of the native fluorescence of both drugs in acetonitrile at λem 330 and 470 nm after excitation at 280 and 275 nm for tadalafi...

Sildenafil and vardenafil, two selective inhibitors of phosphodiesterase type 5 (PDE5) are able, when applied by intraperitoneal injection, to activate chloride transport in cystic fibrosis (CF) mice homozygous for the F508del mutation. Oral treatment with the drugs may be associated with adverse haemodynamic effects. We hypothesised that inhaled PDE5 inhibitors are able to restore ion transpor...

OBJECTIVE To explore the drug treatment for temporary ejaculation failure in couple undergoing assisted reproductive technologies (ART). DESIGN Case report. SETTING Andrology unit, center for reproductive medicine. PATIENT (S) Five patients suffering from temporary ejaculation failure during ART. INTERVENTION(S) Assisted reproductive technology. Semen samples were collected by masturbat...

OBJECTIVES To assess whether vardenafil would improve erectile function irrespective of etiology, baseline severity, or patient age. The consistency of the response over time was also evaluated. METHODS A multicenter, randomized, double-blind, placebo-controlled at-home study of vardenafil treatment (5, 10, and 20 mg) was performed. This secondary analysis compared the mean International Inde...

Erectile dysfunction (ED) is a condition that affects approximately 18 million American men. Phosphodiesterase-5 inhibitors (PDE5i’s) have revolutionized the treatment of erectile dysfunction by providing the first highly-effective oral medication. Vardenafil is one of 3 PDE5i’s commercially available for the treatment of ED in the United States. It has demonstrated therapeutic efficacy in the ...
