CERRADA CERRADA, E. et al. Effectiveness of sildenafil in Primary Health Care. Medifam [online]. 2001, vol.11, n.7, pp.25-33. ISSN 1131-5768.

Backgrounds: there aren´t studies about efectiveness of sildenafil in Primary Health Care.  Objectives: to evaluate the effectiveness of sildenafil citrate (ViagraTM) in men with erectile dysfunction (ED) through a questionnaire and a global efficacy question, and their couples' satisfaction degree.  Design: non-aleatory before-after interventional study.  Location: urban primary care center.  Patients: men = 18 years with ED of 6 months or longer.  Methods: socio-demographical variables, associated diseases, ED degree -through the administration before and after treatment of the erectile function field of the International Index of Erectile Function (IIEF) and an after treatment global efficacy question- and a before and after treatment question about their couples' satisfaction degree, were measured. The Wilcoxon test was used to evaluate the improvement at the questionnaire score.  Results: initially, 45 men accepted to participate in the study, with a mean age of 56,8 years (CI 95%: 32,6-81); 11 with mild ED, 21 moderate and 13 severe. Twelve rejected to follow the treatment; five of them were afraid of adverse effects. The 33 subjects that finished the study presented an initial IIEF mean value of 12,73 (CI 95%: 11,22-14,24) and at the end an IIEF score of 24 (CI 95%: 21,47-26,53). This improvement was statistically significant (p<0,0001). Twenty-eight experienced subjective improvement. Three patients suffered headache and 2 flush. Twenty of the 23 mates (all women) that participated in the study referred increase in their sexual satisfaction degree.  Conclusions: sildenafil has demonstrated to be effective in our study population, as it was in other studies though the limitations of the design and size of the study.
