Linsidomine (3-morpholinosydnonimine or SIN-1^[1]) is a vasodilator. It is a metabolite of the antianginal drug molsidomine and acts by releasing NO from the endothelial cells nonenzymatically. It also hyperpolarizes the cell membrane through influencing the sodium-potassium pump and thereby rendering it less responsive to adrenergic stimulation. Linsidomine injection at a dose of 1 mg produces usable erection^[2] in about 70% of patients and full erection in up to 50% of patients. Linsidomine does not appear to be associated with priapism.^{[citation needed]}

Linsidomine is neurotoxic and promotes oxidative stress on neurons.^[3] Linsidomine is a peroxynitrite-generating compound involved in the pathogenesis of neurodegenerative diseases.^[4]
