ATROPINE (AUTOINJECTOR) vs PAMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3, M4, M5), blocking the effects of acetylcholine and other cholinergic agonists.
Antimuscarinic; competitively blocks acetylcholine at muscarinic receptors, reducing smooth muscle spasm and secretions.
2 to 4 mg intramuscularly (lateral thigh) or intravenously, repeated every 10-20 minutes if needed until muscarinic signs abate, maximum 3 doses.
2.5 mg orally or subcutaneously 30-60 minutes before meals and at bedtime; maximum 10 mg/day.

Terminal elimination half-life: 2-4 hours (adults); prolonged to 6-12 hours in elderly or hepatic impairment.
1.5-2 hours, necessitating dosing every 4-6 hours for sustained therapeutic effect.
Renal: ~30-50% unchanged; hepatic metabolism: ~50%; fecal: minor.
Primarily renal (70-80% unchanged), with 20-30% fecal via biliary elimination.
