Charlie, you probably also noticed that some researchers (Rabey, J. et al:
Neur 1995;45:432-434; Gonski et al: Lancet 1995;345:517-518) are still pushing
Clozaril as an antipsychotic in "low doses" to avoid the dangerous adverse
effect you mention. Personally, I don't think anyone who troubles to read
the package info in the PDR would opt for this drug despite its
admitted effectiveness.
Cheers, Joe
