title: Nitric oxide donor, linsidomine chlorhydrate (SIN-1), in the diagnosis and treatment of erectile dysfunction: critical appraisal and review of the literature.
abstract: Recent experimental work has demonstrated that nitric oxide (NO) is the neutrotransmitter responsible for cavernous smooth muscle relaxation. Different studies on the performance of the direct NO-donor linsidomine chlorhydrate (SIN-1) in patients with erectile dysfunction have come to conflicting results ranging from highest praise to complete dismissal. We reviewed all published studies on the use of SIN-1 for intracorporeal injection in erectile failure including our own. To this date, 3 groups published their data. Only the uncontrolled data from Hannover claim good results. The controlled data from Hamburg and Berlin on patients with erectile failure due to venous leakage, to a mixed aetiology in a double-blind fashion and to mixed aetiology with drug increase (1 mg versus 2 mg of SIN-1) showed a significantly worse performance of SIN-1 compared to the standard drug for penile injection, prostaglandin E1. We conclude that there is no place for linsidomine chlorhydrate in either the diagnosis or the treatment of erectile dysfunction.
