Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antimuscarinic agent; competitively blocks acetylcholine at muscarinic receptors, reducing gastrointestinal motility and secretions.
Antimuscarinic; competitively blocks acetylcholine at postganglionic muscarinic receptors, inhibiting parasympathetic nerve impulses.
5 mg orally three times daily, before meals. May be increased to 20 mg per day if necessary.
15 mg orally 3 times daily before meals and 30 mg at bedtime; initial dose may be 15 mg 3 times daily.

Terminal elimination half-life is approximately 1.5 to 2 hours in adults, requiring frequent dosing for sustained anticholinergic effect.
Terminal half-life 2.5-4 hours; clinically, dosing every 6 hours maintains therapeutic levels.
Renal: ~50% unchanged; biliary/fecal: ~50% as metabolites and unchanged drug.
Approximately 70% renal (tubular secretion) as metabolites and unchanged drug; 30% biliary/fecal.
