ALUMINUM HYDROXIDE AND MAGNESIUM TRISILICATE vs ELIPHOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aluminum hydroxide and magnesium trisilicate act as antacids by neutralizing gastric hydrochloric acid, increasing gastric pH, and inhibiting pepsin activity. Aluminum hydroxide forms aluminum phosphate in the intestine. Magnesium trisilicate reacts with HCl to form magnesium chloride and silicic acid, which may provide additional protective coating.
ELIPHOS is a phosphate binder that works by binding dietary phosphate in the gastrointestinal tract, forming non-absorbable complexes that are excreted in the feces, thereby reducing serum phosphate levels.
10-20 mL (of suspension containing 200 mg aluminum hydroxide and 200 mg magnesium trisilicate per 5 mL) orally 1 hour after meals and at bedtime, up to 4 times daily.
10 mg orally once daily, with or without food.

Aluminum: terminal half-life in patients with normal renal function is approximately 8 hours for absorbed fraction, but may extend to days in renal failure. Magnesium: half-life of absorbed magnesium is 4-6 hours. Clinical context: accumulation risk in chronic kidney disease.
Terminal elimination half-life is 3-5 hours in patients with normal renal function; prolonged in renal impairment.
Aluminum and magnesium ions are minimally absorbed. Absorbed aluminum is primarily excreted renally (elimination half-life prolonged in renal impairment); unabsorbed components are eliminated in feces. Magnesium trisilicate may dissociate; absorbed magnesium is excreted renally. Fecal elimination accounts for >95% of the dose.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; approximately 10% is metabolized.
