The possibility of the participation of this system in the effect of these pyrazolone derivatives on GE was investigated and it was found that acute iv adrenergic blockade with guanitidine or iv pretreatmentwith propranolol (anon-selective [beta]-adrenergicantagonist) abolished the effect of dipyrone and antipyrine on GE (41).
Diagnosis prior to the patient's IOL would have been ideal, as the patient could have been optimized with alpha adrenergic blockade prior to delivery.
Priapism is also exacerbated by alpha 2 adrenergic blockade stimulating the release of a nitric oxide-like substance, which further stimulates erections (10).
