The introduction of orally administered phosphodiesterase-5 inhibitors into clinical practice 10 years ago has been a revolution in the field of urology. The availability of a convenient to use, safe -despite initial concerns- and effective treatment for erectile dysfunction of varying severity and etiology, has radically changed the way that physicians, but most importantly patients, approach this condition. Most of the expectat Read More

PDE5 inhibitors have been clearly established as first-line therapy for the treatment of erectile dysfunction (ED). Three PDE5 inhibitors - sildenafil (Viagra®), vardenafil (Levitra®) and tadalafil (Cialis®) - are currently approved by the FDA and the EMEA for use in ED, whereas sildenafil is also marketed under a different proprietary name (Revatio®) for the treatment of pulmonary arterial hypertension (PAH). A forth PDE5 inhibi Read More

Erectile dysfunction (ED) has been revolutionized during the last two decades, as several treatment options are available today. Phosphodiesterase type 5 (PDE5) inhibitors (sildenafil, tadalafil, vardenafil) are currently the first choice treatment option for ED by most physicians and patients due to their high efficacy rates and favourable safety profiles. Despite the fact that more than 50 million ED patients have been treated succes Read More

Erectile dysfunction (ED) is a common medical condition that has a negative impact on men and their partners. The field has revolutionised over the last two decades and more treatment options are available now for the treatment of ED than ever before. Among available treatment options, the most commonly prescribed therapies are oral phosphodiesterase type 5 (PDE5) inhibitors. The first drug in this class, sildenafil citrat Read More

Erectile dysfunction (ED) is one of the most challenging complications associated with radical prostatectomy (RP) for clinically localized prostate cancer. Currently, a broad spectrum of therapeutic options are available to improve sexual health after surgical treatment. Several basic science reports highlighted a potential role for phosphodiesterase type 5 inhibitors in the prevention of endothelial damage related to ischemia r Read More

Both lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) have a negative impact on patients' quality of life. The co-prescription of two active agents for these conditions will improve each condition and the addition of one drug to the other may potentiate the primary response of the first treatment and thereby improve the QoL of patients. Several epidemiological studies have indicated that the association betw Read More

This review study refers to the possibility to employ PDE5 inhibitors as an adjunct tool for the therapeutic management of male infertility. The literature tends to suggest that PDE5 inhibitors enhance the Leydig cell secretory function and play a role in the regulation of the contractility of the tunica albuginea and the epididymis. In addition, the literature suggests that PDE5 inhibitors increase the prostatic secretory function th Read More

Phosphodiesterase type-5 (PDE5) inhibitors are widely used as first-line therapy for erectile dysfunction (ED). Their efficacy and safety combined with an increasing understanding of cyclic guanosine monophosphate (cGMP)- regulated mechanisms, have triggered a number of attempts to determine their effects and potential benefits in nonurological conditions. In recent years, extensive and diverse preclinical and clinical e Read More

PDE-5 inhibitors were originally studied in cardiovascular indications but were later developed and approved for on-demand treatment of erectile dysfunction (ED). A few years ago sildenafil was approved for the treatment of pulmonary hypertension, thus renewing interest in cardiovascular applications, and tadalafil became available in oncedaily formulations for erectile dysfunction management. Given the wide distribution Read More

Recent progresses in the development of fluorescent technologies become a reliable device for drug discovery research. The fluorescence tools offer attractive options for an opportunity to visualize the effects of drug candidates in the cells. The fluorescent tools, such as fluorescent protein, are regularly used in a range of drug discovery processes. A better understanding and use of fluorescent technologies facilitate drug dis Read More

Calcitonin gene-related peptide (CGRP) is a polypeptide produced by alternative processing of calcitonin gene transcripts and is endowed with important systemic physiological effects. The recent characterization of its receptor and the discovery of stable antagonists has addressed them in the indication migraine. Beside this, several studies have been focused on role of CGRP at gastric level. CGRP is considered a marker of Read More

Angiogenesis and inflammation are closely integrated processes. Fibroblast growth factor-2 (FGF2) is a prototypic angiogenesis inducer belonging to the family of the heparin-binding FGF growth factors. FGF2 exerts its proangiogenic activity by interacting with various endothelial cell surface receptors, including tyrosine kinase receptors, heparan-sulfate proteoglycans, and integrins. A tight cross-talk exists between FGF2 and t Read More
