Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Recombinant human α-galactosidase A enzyme that hydrolyzes globotriaosylceramide (Gb3) and other glycosphingolipids with terminal α-galactosyl groups, thereby reducing accumulation in tissues.
Human recombinant tissue-nonspecific alkaline phosphatase (TNSALP) that hydrolyzes inorganic pyrophosphate (PPi), a natural inhibitor of hydroxyapatite crystal growth, thereby promoting bone mineralization.
1 mg/kg intravenously over 2 hours every 2 weeks.
6 mg/kg administered subcutaneously once weekly.

Terminal elimination half-life approximately 0.5–1 hour; short half-life necessitates twice-weekly intravenous dosing.
Terminal elimination half-life approximately 5.1 days (123 hours) in adults; supports once-weekly subcutaneous dosing for sustained pharmacodynamic effect.
Primarily eliminated via renal excretion as intact protein; minimal biliary/fecal elimination (<1%).
Renal (primarily via proteolytic catabolism into small peptides and amino acids); negligible biliary or fecal elimination.
