Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ammonium chloride is an acidifying agent. It dissociates into ammonium and chloride ions. The ammonium ion is metabolized in the liver to urea and hydrogen ions, leading to metabolic acidosis. This reduces blood pH and increases renal excretion of alkaline urine.
FLOWTUSS (guaifenesin) is an expectorant that increases respiratory tract fluid secretions, reducing mucus viscosity and facilitating clearance.
For metabolic alkalosis: 1.5 to 3 g (approximately 280 to 560 mEq) intravenously over 4 to 6 hours; adjust based on serum chloride and pH.
10 mg orally every 4-6 hours as needed for cough; maximum 60 mg/day.

4-6 hours; prolonged in renal impairment (up to 12-15 hours).
Terminal elimination half-life is 4–6 hours in adults with normal renal function; prolonged to 8–12 hours in moderate renal impairment (CrCl 30–50 mL/min).
Renal: >99% as ammonium ion and chloride; minimal biliary/fecal elimination.
Renal elimination of unchanged drug accounts for 60–70%; hepatic metabolism (30–40%) with fecal excretion of metabolites via bile (20–25%) and urine (10–15%).
