Levitra (vardenafil) is a medication used to treat erectile dysfunction (ED). It belongs to a class of drugs called phosphodiesterase-5 (PDE5) inhibitors.
Levitra works by increasing blood flow to the penis. This happens when a man becomes sexually stimulated; Levitra enhances this process. Specifically, it inhibits PDE5, an enzyme that breaks down cyclic GMP, a molecule crucial for achieving and maintaining an erection.
By blocking PDE5, Levitra allows cyclic GMP levels to remain high, leading to smooth muscle relaxation in the blood vessels of the penis. This relaxation allows increased blood flow, resulting in a firmer, longer-lasting erection.
Remember to consult a doctor before using Levitra, as it may interact with other medications or be unsuitable for individuals with certain health conditions. They can help determine the appropriate dosage and assess any potential risks.
Levitra typically takes effect within 30 to 60 minutes and its effects can last for up to 4-5 hours. The duration and intensity of the effects may vary depending on individual factors and dosage.
