Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Arginine is a semi-essential amino acid that serves as a substrate for nitric oxide (NO) synthesis via nitric oxide synthase (NOS), leading to vasodilation. It also stimulates growth hormone release and is involved in the urea cycle for ammonia detoxification.
Xylose is a pentose sugar that is absorbed in the small intestine via passive diffusion and active transport. It is used to assess intestinal mucosal integrity; its absorption reflects the function of the enterocytes. After absorption, it is not metabolized and is excreted unchanged in urine, making it a marker for intestinal absorption and renal function.
10 mg intravenously over 1-2 minutes, once daily for 5 days, repeat course after 2-3 weeks if needed.
Adults: 25 g orally in 500 mL water, administered as a single dose for D-xylose absorption test.

Terminal elimination half-life is 2-4 hours (mean 3 hours) in adults with normal renal function; prolonged to 8-18 hours in renal impairment.
Terminal elimination half-life: 1.2-2.5 hours in adults with normal renal function; prolonged in renal impairment (up to 10 hours).
Primarily renal (approximately 80-90% unchanged). Biliary/fecal elimination accounts for <5%.
Renal: approximately 85-90% eliminated unchanged in urine; biliary/fecal: negligible (<5%).
