The primary and active ingredient in Tadalista 10 mg is the PDE 5 inhibitor tadalafil. Rather than applying a Band-Aid fix, it tackles the underlying source of the issue to give you long-term relief. It controls blood flow, which is necessary to maintain an erection and a robust penis during the duration of sexual activity. Because the penis stays firm and erect for the time that it receives a continuous supply of blood, you can enjoy it worry-free.
