Are there any new/recomended medications for ADD?


I am the wife of my ADD Husband. We live in New Zealand and therefore why I am asking for advice on what medications have been found that may work better than Ritalin. My husband has not taken anything since us shifting to a rural town, but he is now keen to get back on track. I have read a bit about Wellbutrin, is this a common medication? Any advice would be greatly appreciated :-) Thank you, Melita
