Alzheimer's disease is a chronic neurodegenerative disorder that is characterized by memory impairment, cognitive dysfunction, behavioral disturbances, and deficits in activities of daily living. A consistent observation in these patients is that cholinergic neurons are affected and deteriorate over time

Arzneimittel-Forschung, 49(7), 557-565 (1999-08-12)
A systematic analysis of the existing literature has been undertaken to compare the therapeutic and operational profiles of metrifonate (CAS 52-68-6), and praziquantel (CAS 55-268-74-1), two anti-schistosomal compounds. The criteria evaluated were therapeutic efficacy against Schistosoma haematobium and other helminths

Metrifonate, administered orally to patients with probable Alzheimer's disease in a once-daily dose, readily enters the brain and inhibits brain acetylcholinesterase (AChE) activity in a dose-dependent fashion. Metrifonate is a prodrug, converted non-enzymatically to 2,2-dichlorovinyl dimethyl phosphate, a long-acting inhibitor
