Mechanism and action
Ativan: Lorazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance. Caverject: 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.
