Ibuprofen and aspirin share some similarities but are different molecules. Both ibuprofen and aspirin are available in the US, both are also available in Europe. It's not the same as - for example - Tylenol which is called Doliprane or Dafalgan in Europe. In that case the active molecule is the exact same, just the name is changing; but you will have a hard time finding a box with Tylenol written on it in France.
