What is Levitra?
Levitra (vardenafil) is an FDA-approved oral therapy for erectile dysfunction (ED). Unlike hormonal treatments, it targets the physiological processes required for an erection by enhancing blood vessel relaxation in the penis. This temporary effect occurs only when combined with sexual stimulation.
Active Ingredient and Mechanism
Vardenafil inhibits the PDE5 enzyme, which regulates blood flow in erectile tissue. By blocking PDE5, it promotes the accumulation of cyclic GMP—a molecule that relaxes penile blood vessels—improving circulation during arousal. This mechanism is inactive without sexual excitement.
Brand vs. Generic
Levitra is the original brand-name product. Generic versions (e.g., Vardenafil Hydrochloride) are bioequivalent and rigorously tested for consistency in potency and safety.
Available Forms
The medication is supplied as orange, film-coated tablets. The 20 mg dose is standard for most patients, though lower strengths are available for those with health concerns like cardiovascular issues.
Unique Features
- Faster onset (as early as 25 minutes) compared to some ED medications.
- Less impacted by moderate-fat meals than older PDE5 inhibitors.
- Shorter half-life (4–5 hours) reduces the risk of prolonged side effects.
