Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Theophylline relaxes bronchial smooth muscle by inhibiting phosphodiesterase, increasing intracellular cAMP, and antagonizing adenosine receptors.
Selective inhibitor of the sodium-glucose cotransporter 2 (SGLT2) in the proximal renal tubules, reducing glucose reabsorption and lowering blood glucose levels.
100 mg orally every 6 hours; adjust based on serum theophylline concentrations and clinical response (target 5-15 mcg/mL).
XTRELUS (luseogliflozin) 2.5 mg orally once daily, increased to 5 mg once daily if needed.

Terminal elimination half-life is approximately 8-12 hours in healthy adults. In smokers, half-life is reduced by 50%; in patients with hepatic cirrhosis or heart failure, half-life is prolonged to 24-36 hours.
The terminal elimination half-life is approximately 12 hours in patients with normal renal function. In patients with moderate renal impairment (CrCl 30-50 mL/min), half-life is prolonged to 20-24 hours, necessitating dose adjustment.
Renal excretion accounts for approximately 10% of the administered dose as unchanged drug. The remainder is hepatically metabolized, with metabolites excreted renally. Biliary/fecal elimination is negligible (<5%).
Renal excretion accounts for approximately 65% of the administered dose as unchanged drug, with an additional 20% as metabolites. Biliary/fecal excretion accounts for the remaining 15%, primarily as metabolites.
