PORCINE SECRETIN vs PRE-PEN
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.
Benzylpenicilloyl polylysine is a skin test reagent that elicits a wheal-and-flare response in penicillin-allergic individuals by binding to penicillin-specific IgE antibodies on mast cells, triggering histamine release.
0.2 mcg/kg intravenous bolus over 1 minute, maximum 20 mcg.
0.25 mL intradermal injection of a 1:100 dilution (0.25 mg/mL) for skin testing; if negative, proceed to 0.05 mL intradermal injection of 1:10 dilution (2.5 mg/mL).

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: 0.5-1.0 hour in patients with normal renal function. Clinical context: Rapid elimination allows for short duration of action; half-life is prolonged 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 excretion (60-80% as unchanged drug and metabolites). Biliary/fecal elimination accounts for <10%.
