The operation method and expected timing
Vardenafil is a member of the phosphodiesterase type 5 inhibitor class. When sexual stimulation occurs, it helps preserve cyclic GMP levels in penile tissue, supporting smooth muscle relaxation and increased blood flow needed for an erection.
- Typical onset: many men notice an effect within 30 to 60 minutes; some report a faster onset compared with sildenafil.
- Duration: effects can last several hours but vary by individual, dose, and whether taken with a heavy meal.
- Visual effects: some users may experience changes in color perception or increased light sensitivity; these are generally less common than with some other agents.
Remember that sexual stimulation is required for the drug to facilitate an erection.
