About Urinary Alkalinizers.

Urinary alkalinizers are a therapeutic class of systemic agents—predominantly composed of citrate salts such as potassium citrate or sodium bicarbonate—that reduce the acidity of urine.

Following systemic absorption and metabolic conversion, these agents promote base excretion by the kidneys, raising urinary pH and augmenting urinary citrate levels to inhibit crystalline precipitation and improve the solubility of poorly soluble weak acids.

Clinically, they are primary therapies in nephrology and urology for preventing and managing recurrent nephrolithiasis, including uric acid, cystine, and hypocitraturic calcium oxalate stones, as well as managing renal tubular acidosis.

They are also utilized in clinical toxicology and oncology to enhance the renal elimination of weak-acid toxins, such as salicylates, and to prevent crystal nephropathy during high-dose methotrexate therapy.
