[Metaraminol--an antidote in corpus cavernosum autoinjection therapy-induced prolonged erection]

Up to now 65 patients with erectile dysfunction were treated by means of corpus cavernosum-autoinjection-therapy (CAT). The only side effect observed were 6 prolonged erections, which could successfully be treated in 3 cases by puncture and aspiration of the corpora cavernosa. In another 3 cases prolonged erection subsided after an intracavernous injection of 2 mg metaraminol. Erection induced by CAT was immediately interrupted by metaraminol in 10 other patients.
