Sildenafil (Viagra) in the treatment of male erectile dysfunction in Nairobi
Abstract
OBJECTIVE: To evaluate the effectiveness of sildenafil (Viagra) in the treatment of male erectile dysfunction in Nairobi.
DESIGN: Prospective open label extension study.
SETTING: Urology clinics at the Nairobi Hospital, Kenyatta National Hospital and the author's private clinic in Hurlingham, Nairobi.
PARTICIPANTS: Two hundred and nineteen adult male patients with erectile dysfunction.
RESULTS: The age range was 33-80 years with a mean of 62.5 years and a peak incidence in the 60-69 year age group. One hundred and nineteen patients (54.34%) had organic causes, 85 patients (38.81%) had psychogenic causes and 15 patients had mixed causes. Two hundred patients (91.32%) had improved sexual function after treatment with viagra. This improvement was sustained during the study period of sixteen weeks and included improved erectile and orgasmic functions and overall sexual satisfaction. One hundred and fifty seven of these patients responded to therapy with 50 mg of viagra; 40 patients with 25 mg and three patients with 100 mg of therapy. Nineteen patients (8.68%) had no improvement in sexual function after viagra administration. Seven patients (3.2%) had adverse effects which were mild and transient. They included mild headaches in three patients, mild dyspepsia in two patients and facial flushing and nausea and vomiting in one patient, respectively.
CONCLUSION: Oral sildenafil (Viagra) is an effective well tolerated and simple treatment for male erectile dysfunction in the…
