Vardenafil is a PDE5 inhibitor that is approved by the FDA to treat erectile dysfunction or impotence in men. It is an effective ED medicine that helps to enable erection within 30 to 60 minutes of intake. It allows men to enjoy intimate relations for a desired time by helping to keep an erection. The peak plasma concentration of the ED medicine reaches 30 minutes to 2 hours.
The half-life of Vardenafil is 4 to 5 hours. It means that after this time, half of the concentration of the medicine wears out. Therefore, in most cases, Vardenafil lasts for 4 to 5 hours.
Various factors such as the age of the person, dosage, alcohol intake, drug interaction, and health issues can affect the duration of action of the medicine.
