What's the same
Caverject and Vardenafil both belong to the Erectile Dysfunction (ED) class and are used for partially overlapping indications. The active ingredients — Alprostadil vs Vardenafil — share the same therapeutic approach, so many safety and management points carry across both.
Key differences
Meaningful differences are in active ingredient (Alprostadil vs Vardenafil), strengths (10mcg, 20mcg, 40mcg vs 5mg, 10mg, 20mg), forms (injection vs tablet), and the mechanism, half-life and side-effect nuances that distinguish members of the class.
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. Vardenafil: The mechanism is identical to original Levitra: vardenafil selectively inhibits PDE5 in penile smooth muscle, allowing cyclic GMP produced during sexual arousal to accumulate.
When Caverject is preferred
Caverject is approved for erectile dysfunction of vasculogenic, neurogenic, psychogenic or mixed aetiology in adult men.
When Vardenafil is preferred
Generic vardenafil shares the indication of the originator: erectile dysfunction in adult men.
