Mechanism and action
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. Lexapro: Lexapro acts by selectively inhibiting the serotonin reuptake transporter (SERT) at the synapse, increasing serotonin availability for postsynaptic receptors.
