Filitra 20 mg contains vardenafil, a PDE5 inhibitor used to treat erectile dysfunction (ED). Current healthcare information increasingly emphasizes not only whether an ED medicine works, but also medication safety, cardiovascular health, drug interactions, and the underlying causes of ED. One important healthcare trend is greater attention to cardiovascular risk assessment before prescribing ED medicines. Vardenafil can temporarily lower blood pressure, and people with certain cardiovascular conditions may require medical evaluation before treatment.
