Is atomoxetine the same as Vyvanse?

Excuse me, could you clarify for me if atomoxetine and Vyvanse are one and the same? I've heard about both of them in the context of treating attention deficit hyperactivity disorder, but I'm not entirely sure if they're interchangeable or if they serve distinct purposes. It would be great if you could elaborate on their similarities and differences, if any. Thank you in advance for your time and expertise.
