ADLARITY vs EXELON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADLARITY is a transdermal formulation of donepezil, a reversible acetylcholinesterase inhibitor that increases acetylcholine levels in the central nervous system, improving cholinergic neurotransmission in the cerebral cortex.
Exelon (rivastigmine) is a reversible, non-competitive acetylcholinesterase and butyrylcholinesterase inhibitor, increasing acetylcholine levels in the brain.
10 mg transdermal patch applied once daily to clean, dry, hairless skin on the back, chest, or upper arm.
Initial: 1.5 mg orally twice daily; after 2 weeks increase to 3 mg twice daily; then after 2 weeks increase to 4.5 mg twice daily; then after 2 weeks increase to 6 mg twice daily (maximum). For transdermal patch: initial 4.6 mg/24 hr applied once daily; after 4 weeks increase to 9.5 mg/24 hr; may increase to 13.3 mg/24 hr after additional 4 weeks.

Terminal half-life approximately 70 hours (range 50-100 hours); steady-state achieved within 14-21 days; once-daily dosing due to long half-life.
Terminal half-life: ~1.5 hours; clinical context: tid dosing recommended due to rapid elimination.
Renal: ~60% as unchanged donepezil and metabolites (primarily donepezil, 6-O-desmethyl donepezil, and donepezil-N-oxide); fecal: ~15-20% (biliary excretion of metabolites); minor via urine as conjugates.
Renal (97%) with unchanged drug <1%; biliary/fecal as metabolites.
