CANTIL vs GLYCOPYRROLATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CANTIL (mepenzolate bromide) is a quaternary ammonium anticholinergic agent that blocks muscarinic acetylcholine receptors, reducing gastrointestinal motility and gastric acid secretion.
Glycopyrrolate is a quaternary ammonium anticholinergic agent that competitively antagonizes acetylcholine at muscarinic receptors in the autonomic nervous system, thereby reducing salivary, gastric, and bronchial secretions. It also exhibits antispasmodic effects on gastrointestinal smooth muscle.
50 mg orally three times daily, may increase to 100 mg three times daily if needed
1-2 mg orally 2-3 times daily; maximum 8 mg/day. For parenteral use: 0.1-0.2 mg IV/IM every 4-6 hours as needed.

Terminal elimination half-life is approximately 10-12 hours; clinically, this supports twice-daily dosing in patients with normal renal function.
Terminal elimination half-life: 0.6-1.2 hours (IM/IV), with prolonged duration in elderly and renal impairment.
Primarily renal excretion of unchanged drug and metabolites; approximately 60-70% eliminated renally, with about 30-40% excreted in feces via biliary elimination.
Primarily renal excretion of unchanged drug (85-90%) with biliary/fecal elimination accounting for <10%.
