A case of priapism following oral intake of papaverine hydrochloride (
300 mg) is reported. The priapism persisted after coitus. It resisted
conservative treatment, but responded to aspiration of the corpora cav
ernosa and irrigation with phenylephrine solution. We found no earlier
report of priapism induced by oral papaverine. The possible therapeut
ic role of oral papaverine in impotence merits study.
