Re: Udate on Clozaril
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 J. R.
