title: [Dose correcting factors in the treatment of erectile dysfunction with viagra].
abstract: 28 patients with erectile dysfunction of different origin received viagra (25, 50 or 100 mg depending on the effect and tolerance). The examination on the treatment week 4, 8 and 12 stated a 85% response. It was found that patients with body mass more than 90 kg benefited most in the dose 100 mg. Maximal single dose 100 mg is recommended for patients over 65 years of age. A 100% response was observed in patients with psychogenic and arteriogenic erectile dysfunction. Low effectiveness of viagra in patients with neurogenic erectile dysfunction can be explained by damaged parasympathetic nerve fibers. Thus, in the decision on viagra dose it is advisable to consider the patient's body mass, age and etiology of erectile dysfunction.
