Objectives. To evaluate the efficacy of sildenafil and selective serotonin reuptake inhibitor in alleviating premature ejaculation (PE) in patients in whom other treatments had failed. Methods. Healthy men evaluated for primary PE graded their ejaculation on a scale of 0 to 8 (0 = almost never, 8 = almost always). The intravaginal ejaculatory latency time (IVELT) was graded on a scale of 0 to 3 (0 = longer than 5 minutes, 3 = shorter than 1 minute). The 138 men who scored their PE as 4 or greater and IVELT as 2 or greater comprised the study group. Psychological and behavioral counseling was provided during the study. PE was graded using the same scales 3 months after the initiation of each treatment. Topical 5% lidocaine ointment comprised the initial treatment: dissatisfied patients (PE grade 4 or greater, IVELT 2 or greater), took one tablet of paroxetine 20 mg for 30 days and then one tablet 7 hours before intercourse. Sildenafil was added to the treatment of patients dissatisfied with paroxetine alone. Results. The mean initial PE grade was 5.67 ± 0.13 and that for IVELT was 2.9 ± 0.19 for all participants (mean age 28.7 years). Thirty-eight reported improvement (PE grade 2.0 ± 0.8, P <0.01; IVELT 0.13 ± 0.34, P <0.001) after local lidocaine application. Of the 100 treated with paroxetine, 42 reported improvement (PE grade 2.5 ± 0.1, P <0.01; IVELT 0.28 ± 0.46, P <0.001), and 56 of the remaining 58 who were treated with a combination of paroxetine and sildenafil reported improvement (PE grade 1.78 ± 0.23, P <0.001; IVELT 0.16 ± 0.37, P <0.001). Two patients remained dissatisfied with all treatment modalities. Conclusions. Sildenafil combined with paroxetine and psychological and behavioral counseling alleviated PE in patients in whom other treatments failed. © 2003, Elsevier Science Inc.
