Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcium chloride dissociates to provide calcium ions, which are essential for myocardial contractility, nerve impulse transmission, and blood coagulation. It antagonizes the cardiotoxic effects of hyperkalemia by stabilizing cardiac cell membrane potential.
Hemichlor (HEMICLOR) is a brand name for a combination product containing chlorpheniramine and pseudoephedrine. Chlorpheniramine is a first-generation antihistamine that antagonizes histamine at H1 receptor sites, reducing allergic symptoms. Pseudoephedrine is a sympathomimetic amine that directly stimulates alpha-adrenergic receptors, causing vasoconstriction and decongestion.
IV: 500 mg to 1 g (5-10 mL of 10% solution) administered slowly at a rate not exceeding 0.5-1 mL/min; may be repeated every 1-3 days based on serum calcium levels.
50-100 mg intravenously every 6 hours or 100 mg orally every 12 hours.

Terminal half-life ~4-6 hours for rapid distribution phase; prolonged in renal impairment (up to 24-48 hours).
Terminal elimination half-life 18–24 hours in normal renal function; prolonged to 36–48 hours in moderate renal impairment (CrCl 30–50 mL/min); adjust dosing interval in renal disease.
Primarily renal (>80% as ionized calcium); minor fecal elimination (10-20%) via endogenous secretion; negligible biliary excretion.
Primarily renal (85–90% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal < 5%.
