Sildenafil and Tadalafil

Inability to have or keep the erection long enough for performing a coitus means that a man suffers from impotence. To help this situation, one may try either sildenafil or tadalafil.

Sildenafil and Tadalafil belong to PDE5 inhibitors. They improve the flow of blood to the penile area due to the influence on the smooth muscles of the blood vessels. They relax and let the cavernous bodies of the penis fill with blood. It helps to get a firm and durable erection. Yet the pills themselves cannot make the penis erected: a man needs to feel sexual arousal to get the effect.

Both preparations have a common mechanism of action though the onset and the durability of their impact differ. Besides, they have the same contraindications to usage:

  • Intake of nitrate-containing drugs (for example for angina treatment);
  • Heart ailments like arrhythmia, pain in chest and heart failure;
  • Uncontrolled hypertension or too low blood pressure;
  • Allergy to any active or inactive component of the drug;
  • A stroke or a heart attack in the last 6 months.
