Both Vardenafil and Viagra treat erectile dysfunction by inhibiting phosphodiesterase-5 (PDE5), an enzyme that breaks down cyclic GMP. Increased cyclic GMP levels relax smooth muscles in the penis, allowing increased blood flow and facilitating an erection. Vardenafil, however, shows a higher selectivity for PDE5 than Viagra (sildenafil).
Vardenafil’s Advantages
This higher selectivity may translate to fewer side effects for some men. Studies suggest Vardenafil’s onset of action is quicker than Viagra’s, potentially leading to faster results. The duration of effect can vary depending on individual factors but is generally comparable.
Dosage and Efficacy
Vardenafil HCL 20mg is a common dosage, often showing high efficacy rates in clinical trials. However, individual responses vary significantly. Efficacy depends on factors like overall health, age, and the severity of erectile dysfunction. Direct comparison of efficacy needs consideration of various clinical trial methodologies and patient populations. Always consult a doctor before initiating treatment. They can help determine the optimal dosage and monitor for side effects.
Side Effects and Considerations
Common side effects for both drugs include headache, flushing, nasal congestion, and visual disturbances. Rare but serious side effects are possible; a doctor should be contacted immediately if these occur. Men with heart conditions, low blood pressure, or certain eye problems should discuss use with their physician before taking either medication.
