Which Among Febutaz And Zyloric Is Better To Control Uric Acid?

I was taking Zyloric tab 100 OD for last 3 years. Uric acid which was around 8.2 before is around 4.5 for the last 2 years. Now the doctor has prescribed tab febutaz 40 OD in place of Zyloric. Have i to take either of it as my uric acid is OK? If yes, which one is better?
