Metrifonate is an excellent drug for the treatment of urinary schistosomiasis in areas with S. haematobium monoinfection. Toxicity apparently is negligible. Side effects due to the inhibition of acetylcholinesterase are usually scarce, light and transient in nature. At the recommended

The Cochrane database of systematic reviews, (2)(2), CD003155-CD003155 (2006-04-21)
Metrifonate is a long-acting irreversible cholinesterase inhibitor, originally used to treat schistosomiasis. Its potential to enhance central nervous system cholinergic neurotransmission led to clinical trials for the treatment of people with Alzheimer's disease (AD). Although low incidence of serious side

The pharmacology, pharmacokinetics, clinical efficacy, and adverse effects of metrifonate, a long-acting cholinesterase inhibitor, are discussed. Attempts to correct the central cholinergic deficits associated with Alzheimer's disease have included administration of cholinergic precursors, cholinergic agonists, and cholinesterase inhibitors. To date
J L Cummings
Pharmacotherapy, 18(2 Pt 2), 43-46 (1998-04-16)
Metrifonate is a cholinesterase inhibitor with a long-lasting inhibition that raises brain acetylcholine levels. It is well-absorbed and has limited binding to serum proteins. In preliminary studies of its utility in the treatment of Alzheimer disease's (AD), it led to
P N Tariot
The Journal of clinical psychiatry, 59 Suppl 9, 33-37 (1998-08-28)
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
