schizophrenia - antipsychotics -phenothiazines: adverse effects -\_\_\_\_\_\_\_\_\_ effects -\_\_\_\_\_\_\_\_, \_\_\_\_\_\_\_\_, \_\_\_\_\_\_, \_\_\_\_\_\_\_\_ may be due to blockage of \_\_\_\_ receptors present in the \_\_\_\_\_\_\_ -sedation -anticholinergic effects -orthostatic hypotension -adverse effects need to be managed
extrapyramidal akathisia pseudoparkinsonism dystonia tardive dyskinesia sigma red. nucleus
schizophrenia - antipsychotics
Thioxanthenes

schizophrenia - antipsychotics Butyrophenones - \_\_\_\_\_\_\_\_\_ (Haldol) -first drug used for schizophrenia -significant \_\_\_\_\_\_\_ effects -extensively metabolized in the \_\_\_\_ -excreted in \_\_\_\_\_ and \_\_\_\_ -used to manage \_\_\_\_\_\_ syndrome -facial and vocal tics, coprolalia, echolalia
haloperidol extrapyramidal liver urine, bile Tourette's
Schizophrenia - antipsychotics Azepines (Atypical) -\_\_\_\_\_\_\_\_, \_\_\_\_\_\_\_\_, \_\_\_\_\_\_\_\_\_ -atypical antipsychotic -\_\_\_\_\_ extrapyramidal effects -therapeutic effects via blocking \_\_\_. and \_\_\_\_\_. receptors -has ability to block \_\_\_\_\_\_\_\_\_ receptors. -may also cause \_\_\_\_\_\_
clozapine, loxapine, olanzapine fewer D2, 5HT2 histamine toxicity
schizophrenia - antipsychotics Clozapine (Clozaril) -\_\_\_\_ extrapyramidal effects -significant \_\_\_\_\_\_ and \_\_\_\_\_\_\_ effects --due to its ability to block \_\_\_\_\_\_, \_\_\_\_\_\_ and \_\_\_\_\_ adrenergic receptors --\_\_\_\_\_ gain -potentially fatal \_\_\_\_\_\_\_\_\_. (1-3%) -require weekly monitoring during the first _ months followed by _ months of biweekly \_\_\_\_\_\_\_ counts
