DICYCLOMINE HYDROCHLORIDE (PRESERVATIVE FREE) vs HICON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3) in the gastrointestinal tract, producing antispasmodic effects by reducing smooth muscle contractions.
Unknown; possibly involves modulation of hypothalamic thermoregulatory center.
20 mg intramuscularly every 4-6 hours.
HICON (norepinephrine) 0.05-0.5 mcg/kg/min IV continuous infusion, titrated to blood pressure.
