In clinical practice it is quite common to have sexually active male patients with mild/normal erectile function that are not satisfied with their sexual function. The aim of this study is to evaluate the effect of sildenafil on the quality of sexual function in this group of patients.
The endpoint of this study is to define another, different group of patients that may respond positively to treatment with sildenafil.
|Condition or disease||Intervention/treatment||Phase|
|Erectile Dysfunction||Drug: sildenafil (viagra)||Phase 4|
This will be a prospective, placebo-controlled, double blind crossover study. One hundred males between 35-70 years of age in good general health will be included. Recruitment of patients will be done through patient referral to the “male sexual dysfunction clinic” at Rambam Medical Center, as well as by other necessary ways for optimal and rapid recruitment (media advertisement, direct contact with primary clinics etc.).
For each patient, the study will terminate after a maximal period of 4 months from initiation and will include 4 visits:
On inclusion (Visit I), a thorough explanation will be given to each patient on the aims and course of the study, as well as a full explanation on dosage, mode of administration, safety and efficacy of Viagra. After reading and signing an informed consent, each patient will be asked to fill a questionnaire regarding his sexual function (IIEF-ED Domain). If the patient fits inclusion criteria, he will be referred to the urologist to initiate the study. On the second encounter (Visit II), medical history and physical exam will be performed. The subject will then fill out 3 questionnaires: IIEF (full version), QVS (quality of sexual life questionnaire) and the SEARS questionnaire. Administration of medication will be performed in a double-blinded crossover fashion. Each patient will be provided, at random either 6 tablets of placebo or Viagra 50mg. The patient will be advised to use them on demand. After consuming all 6 tablets, a third visit will be scheduled. On the third visit (Visit III) each patient will be provided with new IIEF (full version), QVS (quality of sexual life questionnaire), the SEARS questionnaire and an EDITS questionnaire. A few other questions on satisfaction will be asked and recorded (questions on the quality of the erection, duration of intercourse, number of sexual acts per night, frequency of intercourse/week, satisfaction from intercourse etc). Each subject will receive another 6 tablets (Viagra/ placebo). Finally, at the last visit (Visit IV) subjects will again fill out the same questionnaires as on visit III. At the end of the study, double-blind codes will be opened and multi-variant analysis of the data will be performed using chi square and annova.
