Introduction: Hyperuricemia is an abnormally high quantity of uric acid in the blood. Allopurinol is a type of xanthine oxidase inhibitor commonly used to lower uric acid levels in the general population. However, large doses of allopurinol can produce harmful effects, one of which being hepatotoxicity. The antioxidant activity of beetroot powder is high, and it has an antihyperuricemic effect. Giving beetroot powder and allopurinol together is intended to minimize allopurinol's adverse effects and give a positive increase in lowering uric acid levels. This study aims to evaluate the anti hyperuricemia effect of beetroot powder (Beta vulgaris L.) and allopurinol combination in white rats (Rattus novergicus strain Sprague Dawley) induced by potassium oxonate.
Methods: This an experimental study with a randomized pre and post-test control group design. In this experiment, twenty rats were placed into four treatment groups; KP = Positive Control (hyperuricemic rats) + standard feed and drink; G1 = hyperuricemic rats + allopurinol 1,8 mg/Kg BW/day); G2 = Hyperuricemic rats + beet powder 1.56 g/Kg BW/day; G3 = hyperuricemic rats + allopurinol 1,8 mg/Kg BW/day and beetroot powder 1,56 g/Kg BW/day. On day 0 and day 28, the amounts of uric acid were measured. Data obtained were analyzed using SPSS version 23 for windows.
Results: The mean pre-post changes in uric acid levels in each group were KP = 8.97 ± 0.48 mg/dl, G1 = 2.06 ± 0.15 mg/dl, G2 = 2.24 ± 0.10 mg/dl, and G3 = 2.11 ± 0.86 mg/dl. The mean pre-post changes in MDA levels in each group were KP = 8.14 ± 0.39 nmol/mL, G1 = 2.01 ± 0.38 nmol/mL, G2 = 3.13 ± 0.30 nmol/mL, and G3 = 2.35 ± 0.19 nmol/mL.
Conclusion: Beetroot powder and allopurinol combination given for 28 days significantly reduced uric acid and MDA levels in potassium oxonate-induced white rats.
