Besides the role of treating HF, drugs in the group of Sodium-Glucose Transport Protein 2 (SGLT2) inhibitors, Angiotensin-Converting Enzyme Inhibitors (ACEi), and Angiotensin II Receptor Antagonists (ARBs) also have the effect of reducing serum uric acid (Doehner et al., 2022; Kim et al., 2020; Masajtis-Zagajewska, Majer & Nowicki, 2021; McDowell et al., 2022; Schmidt et al., 2001).
