Could Sodium-Glucose Co-Transporter-2 Inhibitors and Glucagon-like Peptide-1 Receptor Agonists Play a Role in Gout Treatment?
Abstract
Gout, a metabolic and autoinflammatory disease, is the most common form of inflammatory arthritis worldwide. Hyperuricemia may result in monosodium urate (MSU) crystals forming and depositing in joints and surrounding tissues, triggering an autoinflammatory response. Effective urate-lowering therapies, as well as anti-inflammatory medications, are used to treat gout. Over the past few decades, new antihyperglycemic drug classes with different modes of action have been added to treat hyperglycemia in type 2 diabetes mellitus (T2DM). Two of these drug classes, sodium-glucose co-transporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists (RAs), have reduced cardiovascular and renal events and mortality. Several clinical studies have demonstrated that SGLT2 inhibitors possess urate-lowering properties, which may be beneficial for treating gout patients, particularly those with comorbid T2DM. Regarding SGLT2 inhibitors, some researchers have suggested that their benefits are partly explained by their ability to reduce serum urate (SU) levels, probably through increased urinary uric acid excretion. The effect of GLP-1 RA on SU levels and urinary excretion of uric acid in humans is unclear. This paper reviews the mechanisms of action of SGLT2 inhibitors and GLP-1RA, both approved and in development. Additionally, it examines what is known about their structure-activity relationships, uricosuric effects, pharmacokinetic profiles, and adverse effects.
