What is the relationship?
Demadex and Alprostadil are different things: Demadex is a branded medication whose active ingredient is Torsemide (in the Diuretics class), whereas Alprostadil is in the Prostaglandin E1 (PGE1) class. They belong to different therapeutic classes and are chosen for different indications.

Mechanisms compared
Demadex: Torsemide blocks the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, producing potent natriuresis and diuresis. Alprostadil: Alprostadil binds prostaglandin E receptors on smooth muscle of the corpus cavernosum, triggering cAMP-mediated relaxation of cavernosal smooth muscle independent of the nitric oxide pathway used by PDE5 inhibitors.
