What is the relationship?
Priligy and Alprostadil are different things: Priligy is a branded medication whose active ingredient is Dapoxetine (in the Erectile Dysfunction (ED) class), whereas Alprostadil is in the Prostaglandin E1 (PGE1) class. They belong to different therapeutic classes and are chosen for different indications.
When Priligy is used

Mechanisms compared
Priligy: Ejaculation is controlled by serotonergic pathways in the central nervous system. 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.
