Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glycopyrrolate is a quaternary ammonium anticholinergic that inhibits muscarinic acetylcholine receptors, thereby reducing salivary secretion and blocking vagally mediated bronchoconstriction.
Trospium is an antimuscarinic agent that competitively inhibits acetylcholine at muscarinic receptors, reducing bladder detrusor muscle contractions.

60 mg orally once daily, taken with a full glass of water at least 1 hour before meals. Extended-release capsule.

Terminal elimination half-life of 4-6 hours; prolonged to 10-12 hours in renal impairment.
Terminal elimination half-life is approximately 7-10 hours in patients with normal renal function; prolonged to 20-30 hours in moderate to severe renal impairment.
Primarily renal excretion of unchanged drug (70-80%) and metabolites; minor biliary excretion (<10%).
Primarily renal excretion (70-80% as unchanged drug and active metabolite); approximately 10% fecal; 5-10% biliary.
