Clozapine and the Treatment of Schizophrenia Essay -- Biological Psych

Clozapine and the Treatment of Schizophrenia Clozapine, marketed by the trade name of "Clozaril," is a member of the dibenzodiazepine class of antipsychotic medication, and is one of many types of neuroleptic drugs. Clozapine is an atypical medication because it differs from the older conventional drugs such as Halodol or Lithium. The difference between atypical and the older drugs is because there less neuroleptic activity as a result of more specific receptors utilized. The atypical drugs work effectively to treat psychotic illnesses and tend to have fewer side effects than their predecessors. Clozapine has been found to be the most effective antipsychotic drug for treatment resistant schizophrenia. Clozapine is used on a limited basis because of the risk of agranullocytosis, where white blood cells are destroyed faster than they are produced, causing the individual to be prone to other illnesses. Two other drugs, either one typical and one atypical, or two atypical medications are used and deemed ineffective before clozapine is used due to the this serious side effect, agranullocytosis. Even thought this risk happens to be small, 1% to 2%, the drug is normally viewed in the psychiatric field as a method of last resort.(Kentridge, 1995) The most common explanation for what occurs in the brain of a schizophrenic is the dopamine hypothesis, where certain areas of the brain have excessive activity at certain dopamine receptors.(Kalat, 2004) This theory will be a reoccurring theme when explaining how clozapine interacts with the body. There are also explanations dealing with clozapine's interaction with the serotonin 5HT2 receptors and the glutamate receptors. ... ...hin a week levels will increase with treatment of colazopine.(Naheed & Green, 2000) Andreasen, N.C.
