PORCINE SECRETIN vs R-GENE 10
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Stimulates exocrine pancreatic secretion by acting on secretin receptors on pancreatic ductal cells, increasing bicarbonate and water secretion. Also stimulates bile and gastric acid secretion.
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.
0.2 mcg/kg intravenous bolus over 1 minute, maximum 20 mcg.
10 mg intravenously over 1-2 minutes, once daily for 5 days, repeat course after 2-3 weeks if needed.

The terminal elimination half-life is approximately 4-6 minutes, reflecting rapid degradation by plasma proteases; this short half-life limits its systemic duration of action and necessitates continuous infusion for sustained secretory testing.
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.
Primarily renal, with over 90% of the administered dose eliminated via glomerular filtration and tubular reabsorption; fecal and biliary excretion are negligible.
Primarily renal (approximately 80-90% unchanged). Biliary/fecal elimination accounts for <5%.
