ADLARITY vs MYTELASE
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.
Mytelase (ambenonium chloride) is a reversible acetylcholinesterase inhibitor that increases acetylcholine concentration at cholinergic synapses by inhibiting its hydrolysis. This enhances neuromuscular transmission and improves muscle strength.
10 mg transdermal patch applied once daily to clean, dry, hairless skin on the back, chest, or upper arm.
Oral: 5–25 mg three times daily; maximum 100 mg/day. IV: 2–5 mg every 2–4 hours as needed for myasthenic crisis.

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.
3-4 hours (short; requires frequent dosing every 3-4 hours for myasthenia gravis management).
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.
Primarily renal (80-90% as unchanged drug via glomerular filtration and tubular secretion); minor biliary/fecal excretion (<5%).
