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.

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.

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.

Objective: To observe the clinical effect and safety of Shanhaidan Granules (SHDG) combined with tadalafil tablets (TT) in the treatment of ED. METHODS: In this open multi-center case-control clinical trial, we enrolled 247 ED patients according to the designed criteria, and treated them orally with SHDG at 10 g per time tid (n = 74), TT at 5 mg per time bid (n = 52), or SHDG + TT at the above doses (n = 121), all for 8 weeks. Before and after medication, we recorded the IIEF-6, erection hardness scores (EHS), traditional Chinese medicine syndromes (TCMS) scores, penile cavernous blood flow parameters and adverse reactions, and compared them between the 3 groups of patients. RESULTS: After 8 weeks of treatment, all the patients showed significantly increased IIEF-6, EHS and TCMS scores in comparison with the baseline (P < 0.05). The total effectiveness rates in the SHDG, TT and SHDG + TT groups were 60.8%, 67.3% and 69.4% respectively based on the IIEF-6 scores, remarkably higher in the TT and SHDG + TT groups than in the SHDG group (P < 0.05), and 40.5%, 32.7% and 63.6% respectively according to the TCMS scores, markedly higher in the SHDG and SHDG + TT groups than in the TT group (P < 0.05). Single-center data manifested significantly increased peak systolic velocity (PSV) of the penile artery in the SHDG + TT and TT groups (P < 0.05). The improvement values of relevant parameters were remarkably higher in the SHDG + TT group than in the TT and SHDG groups, so were IIEF-6 scores in the TT than in the SHDG group, and TCM syndromes in the SHDG than in the TT group. No medication-related adverse events were found in any of patients after treatment, except for some mild side effects including muscle soreness and gastrointestinal reactions in a few cases, all soon relieved, none with abnormalities in blood and urine routine tests or hepatic and renal function indicators. CONCLUSIONS Shanhaidan Granules combined with tadalafil can significantly improve the erectile function and reduce TCM syndromes in ED patients, and therefore can be applied effectively and safely in clinical practice./.

As a long-acting phosphodiesterase type 5 (PDE5) inhibitor, tadalafil is administered orally as the first line therapy for erectile dysfunction (ED). Its efficacy and safety have been confirmed by many clinical studies in the treatment of ED in general patients, elderly patients and those with diabetes mellitus or spinal cord injury or after prostate cancer surgery. With its prolonged action of 36 hours, tadalafil can not only increase the self-esteem of ED men but also improve the quality of life of both the patients and their partners.

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.

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.
