Observation of safety and efficacy of tadalafil for men with erectile dysfunction
Abstract
OBJECTIVE: To observe the safety and efficacy of tadalafil in the treatment of erectile dysfunction in clinical research. METHODS: Eighty patients with ED, before and after 20 mg tadalafil administered orally, received respectively the rigiscan examination with aural and visual sexual stimulation at the same time, and then Bphallic circumference variation, stiffness index, duration were compared before and after the treatment. RESULTS: Phallic stiffness index, duration revealed a statistically (P < 0.05) obvious improvement before and after the treatment for all patients. A significant difference (P < 0.01) on the phallic stiffness index, duration were found between the patients with psychogenic ED and others with organic or mixed ED after the treatment. Overall satisfaction with tadalafil was 82.5%. There was an obvious difference on the curative rates between the patients with psychogenic ED (92.3%) and others with organic ED (68.7%) or mixed ED (58.3%). All adverse events (11 cases of headache and dizziness, 8 cases of digestive canal unwell, 5 cases of flushing, 2 cases of back muscle pain) associated with tadalafil were mild and recovered without any treatment. CONCLUSION: Tadalafil improves erectile function significantly in most patients. Adverse reactions are generally transient and mild to moderate in nature.
