Sertraline and Caverject are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Sertraline belongs to Anti-Depressants while Caverject belongs to Erectile Dysfunction (ED). Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Sertraline: Sertraline selectively blocks the serotonin transporter on the presynaptic neuron, preventing reuptake of serotonin from the synaptic cleft. 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.
When Sertraline is preferred
Generic sertraline shares the indications of the originator: major depressive disorder, panic disorder, OCD, PTSD, social anxiety disorder, and premenstrual dysphoric disorder, all in adults.
When Caverject is preferred
Caverject is approved for erectile dysfunction of vasculogenic, neurogenic, psychogenic or mixed aetiology in adult men.
