ANTRENYL vs DICYCLOMINE HYDROCHLORIDE (PRESERVATIVE FREE)
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antrenyl (oxyphenonium bromide) is a quaternary ammonium anticholinergic agent that competitively blocks acetylcholine at muscarinic receptors in smooth muscle, exocrine glands, and the CNS, leading to reduced gastrointestinal motility and secretion.
Competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3) in the gastrointestinal tract, producing antispasmodic effects by reducing smooth muscle contractions.
50 mg orally 3 times daily initially, then adjust to 50-100 mg 3 times daily; 20 mg intramuscularly or intravenously every 4-6 hours as needed.
20 mg intramuscularly every 4-6 hours.
