AMMONIUM CHLORIDE vs FLOWTUSS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ammonium chloride is an acidifying agent. It dissociates to ammonium and chloride ions. The ammonium ion is converted to urea in the liver, releasing hydrogen ions, which lower blood and urinary pH. It also increases chloride concentration, promoting excretion of bicarbonate and other bases.
FLOWTUSS (guaifenesin) is an expectorant that increases respiratory tract fluid secretions, reducing mucus viscosity and facilitating clearance.
For metabolic alkalosis: 1-2 g orally 3-4 times daily; or 1 g (as 2 mmol/kg) intravenously over 4-6 hours, repeat as needed based on blood gas analysis.
10 mg orally every 4-6 hours as needed for cough; maximum 60 mg/day.

Terminal elimination half-life is approximately 8-12 hours in normal renal function; prolonged in renal impairment (up to 30 hours) due to reliance on renal acid excretion.
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 (NH4+) and chloride (Cl-), with acid excretion via conversion of NH4+ to urea in liver; minimal biliary/fecal.
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%).
