Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Recombinant human iduronate-2-sulfatase (idursulfase) replaces deficient or absent iduronate-2-sulfatase enzyme, which hydrolyzes the 2-sulfate groups from the heparan sulfate and dermatan sulfate GAGs, preventing their accumulation in lysosomes.
SUCRAID (sacrosidase) is a yeast-derived enzyme that hydrolyzes sucrose into glucose and fructose, facilitating absorption in patients with congenital sucrase-isomaltase deficiency.
Intravenous infusion: 1 mg/kg once weekly.
Adults: 1 mL (5 mg/mL) as an oral drop taken with the first bite of each meal. Maximum 5 mL per meal.

Terminal elimination half-life is approximately 100-120 hours. This long half-life supports weekly dosing and maintains therapeutic concentrations throughout the dosing interval.
Intravenous administration: terminal half-life approximately 2.6 hours. Clinical context: Sacrosidase acts locally in the small intestine; systemic absorption is minimal. The short half-life reflects rapid clearance from plasma but does not correlate with intraluminal activity.
Primarily hepatic metabolism; less than 1% excreted unchanged in urine. Biliary/fecal elimination accounts for >90% of the administered dose.
Primarily renal (minimal, as the drug acts locally in the GI tract). Less than 2% of the absorbed dose is excreted unchanged in urine; the majority is metabolized locally and excreted in feces.
