Filitra 40 mg is a medication primarily used for treating erectile dysfunction (ED). It contains Vardenafil as its active ingredient, which works by relaxing the muscles in the walls of blood vessels and increasing blood flow to certain areas of the body, particularly the penis, thereby helping men to achieve and maintain an erection.

In comparison to other medications for ED, such as Viagra (Sildenafil), Cialis (Tadalafil), and Levitra (Vardenafil), Filitra 40 mg shares a similar mechanism of action as Levitra since both contain Vardenafil. However, there are some differences in terms of onset of action, duration of effectiveness, and potential side effects.

Viagra (Sildenafil): This medication typically starts working within 30 to 60 minutes and its effects can last for up to four hours. It's often taken as needed, about 30 minutes to one hour before sexual activity. Common side effects include headache, flushing, indigestion, and nasal congestion.

Cialis (Tadalafil): Known for its longer duration of action, Cialis can start working within 30 minutes to 2 hours and its effects can last for up to 36 hours. It's often referred to as the "weekend pill" because of its prolonged duration of action. Side effects are similar to those of Viagra but can also include back pain and muscle aches.

Levitra (Vardenafil): Like Filitra, Levitra also contains Vardenafil as its active ingredient. It typically starts working within 30 minutes and its effects can last for up to five hours. Common side effects are similar to those of Viagra and Cialis.

The choice between these medications often depends on individual preferences, such as onset and duration of action, tolerability, and potential interactions with other medications.
