title: [Prediction of clinical efficacy of levitra (vardenafil) in patients with arteriogenic erectile dysfunction].
abstract: Oral inhibitors of phosphodiesterase of type 5 (PDE-5) are drugs of choice in therapy of erectile dysfunction (ED). However, 20-30% patients do not respond to them. We studied potentialities of ultrasonic investigation (UI) of postcompression increase in cavernous arteries diameter (PICAD) after intake of vardenafil (levitra, Bayer&GlaxoSmithKline) which is a PDE-5 inhibitor in prediction of clinical efficacy of this medicine. A total of 75 males with ED participated in the study. Significant correlations were found between PICAD after vardenafil administration and clinical efficacy of the drug in patients with arteriogenic ED. The highest response to the drug was observed at PICAD value > or = 50%. High sensitivity and specificity of the PICAD threshold value obtained indicate high potentialities of the method in decision making on treatment policy in patients with organic ED.
