Tadalafil is an effective drug in treating erectile dysfunction (ED), and its clinical efficacy has been confirmed by a great many researches. Tadalafil is distinguished from sildenafil and vardenafil by its prolonged action lasting 36 hours for a sigle dose, compared with about 4 hours for sildenafil. Furthermore, this drug is effective in improving the erectile function of ED patients including those with various comorbid conditions. Tadalafil can help ED patients to regain morning erection and recover the confidence as a man. More and more ED patients choose tadalafil as the first line therapy because of its long efficacy and its conformability to the therapeutic requirement by restoring ED patients to normal, natural and pleasurable sexual life.

A new type of phosphodiesterase 5 inhibitor, Tadalafil, has been used clinically to treat erectile dysfunction (ED). In this review, we analyzed the recent findings from the clinical trials on tadalafil in ED treatment. All data showed that oral tadalafil was an effective and well-tolerated therapeutic for ED, with many potential pharmacological actions. All this may help to give full play to the clinical value of tadalafil.

Erectile dysfunction(ED) is a common ailment in middle-aged and old men. Since tadalafil was introduced into the treatment of ED in October, 2002, more and more ED patients have chosen tadalafil due to its efficacy and safety. The action mechanism, pharmacokinetics, efficacy and safety of tadalafil have been reported in many basic and clinical research documents. This review is to address the safety of tadalafil in treating ED, and provide further guidance for clinicians' choice and safer use of the drug.

OBJECTIVETo explore the correlation between the results of the nocturnal penile tumescence (NPT) test and the efficacy of tadalafil in the treatment of ED.

METHODSA total of 188 ED patients were divided into a normal NPT group (n = 136) and an abnormal NPT group (n = 52) according to the results of the NPT test. All of them were treated with tadalafil at 20 mg 3 times a week. The IIEF-5 score, SEP2, SEP3 and GAQ score were compared between the two groups before and 1 month after the treatment.

RESULTSTadalafil treatment significantly improved IIEF-5 score, SEP2 and SEP3 of both groups of the patients (P < 0.01). Compared with the abnormal NPT group, the normal NPT group showed a remarkable increase in the IIEF-5 score, SEP2, SEP3 (P < 0.05) and GAQ score (P < 0.01).

CONCLUSIONAfter 1 month of tadalafil treatment, the normal NPT group achieved a more significant improvement of erectile function and sexual satisfaction than the abnormal NPT group, suggesting that tadalafil has a better therapeutic effect for ED patients with normal NPT.

OBJECTIVETo investigate the efficacy of tadalafil on nocturnal penile tumescence (NPT).

METHODSThirty-four patients with organic erectile dysfunction (ED) were treated with oral tadalafil at the dose of 10 mg/3 d before bedtime. A month later, 14 of the patients were observed for NPT by nocturnal electrobioimpedance volumetric assessment (NEVA).

RESULTSThe parameters of erectile function significantly improved in the 14 patients (P < 0.05).

CONCLUSIONOral administration of minute dose of tadalafil can improve NPT in organic ED patients.

The benefit of tadalafil should be justified by its safety and tolerance in the chronic treatment of erectile dysfunction (ED) in general and high-risk population. The main treatment-emergent adverse events, chiefly induced by the interactions of tadalafil with PDE5 and isoforms, are mild or moderate in severity, transient and reversible, which may disappear without drug withdrawal. Tadalafil does not add to the risk and severity of cardiovascular problems, and can be safely co-administered with antihypertensives and selective a-receptor blockers.

Phosphodiesterase type 5 (PDE5) inhibitors, sildenafil, tadalafil and vardenafil, are the first-line drugs for the treatment of erectile dysfunction (ED). Giving ED patients the opportunity to try all the three inhibitors can greatly improve the treatment compliance of the patient, whereas the majority of ED patients prefer one specific drug to the others, frequently tadalafil, irrespective of the severity and etiology of the disease, dosing sequence, age of the patient, or dose of medication. Female partners exhibit a similar preference for tadalafil, which has a significant impact on patients' choice. Due to a 36-hour action of tadalafil, patients are allowed to achieve erection within a flexible window of treatment, and not required to schedule the interval between dosing and sexual attempt. The simultaneously decreased time concern will improve the psychological well-being of ED patients and their interpersonal relationship with female partners. Partners who prefer tadalafil feel a return to relaxed and natural sexual activity and the overall improvement in quality of sexual life. The preference of patients and their partners for a specific PDE5 inhibitor should be considered for the purpose of prescription in clinical practice.

ED treatment has changed fundamentally since phosphodiesterase type 5 inhibitor (PDE5-I) came into clinical use. There are three kinds of PDE5-I available at present, Sildenafil, Vardenafil and Tadalafil. Tadalafil distinguishes from the other two by its uniquely long half-life, which lasts 17.5h, which a pharmacodynamic duration of 36h and not influenced by food and alcohol. Thus it may enable ED patients to accomplish a spontaneous intercourse without the need of prior preparation without, which can boost their confidence and self-esteem and, the most important, improve the relationship with their partner. To know patient preference counts quite a lot in optimizing the medication ED treatment.

Erectile dysfunction (ED) seriously affects the quality of men's sexual life. Recent studies have shown that ED is closely related with cardiovascular diseases, and they have many similar pathogenic mechanisms and common risk factors. A great many researches have confirmed the clinical efficacy of tadalafil in the treatment of ED associated with cardiovascular diseases. With its prolonged action of 36 hours, tadalafil can not only increase the self-confidence of ED males but also improve the quality of life of both the patients and their partners.

As a novel phosphodiesterase type 5 (PDE5) inhibitor, tadalafil is administered orally for the treatment of erectile dysfunction (ED). In addition to its outstanding efficacy that lasts 36 hours, tadalafil shows an excellent safety and tolerance, with only a few transient mild to moderate adverse events. Usually ED patients are concomitantly afflicted with multiple pre-existing medical conditions or receive a range of drugs at the same time. Therefore, it is essential to understand its safety in general population and some special high-risk cohorts.
