Terminal half-life approximately 7.6 days (range 5-12 days) after multiple doses; supports monthly dosing.
Terminal half-life approximately 24.6 days (range 23-27 days) in patients with Alzheimer's disease; supports monthly intravenous dosing.
Primarily catabolized to amino acids; not excreted renally or hepatically in unchanged form.
Primarily proteolytic catabolism to amino acids; renal elimination of intact drug is negligible (<1%). Biliary/fecal excretion is not a major route.
