Chapter 13 Flashcards
akathisia
continuous body movement in which an individual is restless or constantly paces about
antianxiety drug
drug used to treat anxiety these drugs are also referred to as anxiolytics
anxiety
a state of anxiousness and hyperemotionalism that occurs with uncertainty, stress and fearful situations
increased by high levels of serotonin
prolonged anxiety causes behavioral and emotional changes
dystonic reaction
reaction characterized by muscle spasms, twitching, facial grimacing, or toticollis
extrapyramidal syndrome (EPS)
movement disorders such as akathisia,dystonia,and parkinsonism caused by anti psychotic drug therapy
neuroleptic malignant syndrom (NMS)
toxic syndrome associated with the use of anti psychotic durgs
parkinsonis
disease or drug induced condition characterized by muscular rigidity, tremors, and disturbances of movement
psychosis
form of mental illness that produces bizarre behavior and deterioration of the personality
schizophrenia
major form of psychosis; behavior is inappropriate
tardive dyskinesia
drug induced involuntary movements of the lips, jaw, tongue, and extremities
antipsychotics
used to treat psychotic behavior
most produce varying degrees of anticholinergic, alpha adrenergic blocking, and antihistaminic effects
what are the “typical” anti psychotic drugs
primarily block D2 receptors. they also produce a higher incidence of EPS because they block dopamine
ex-phenothiazine/ butyrophenone/ thixanthine
what is an “atypical” anti psychotic drug
block 5HT2A receptor
reduce serotonin activity more than they reduce the activity of dopamine, and for that reason they cause a significantly lower incidence of EPS (still may cause EPS tardive dyskinesia, and neuroleptic maligant syndrom)
associated with metabolic disturbances-
weight gain
elevated trigylcerieds
development of diabetes melitius
ex- aripiprazole
clozapine
risperidone
olanzapine
phenothiazines (typical anti psychotic)
refers to the basic chemical structure of a large number of drugs similar in structure and pharmacological action.
block D2 receptors to a greater degree than 5HT2A
posses anti pyschotic,anti cholinergic, antihistaminic,alpha adrenergic blocking and antiemetic effects
reduce symptoms of psychosis without depressing intellectual functions
reduce nausea and vommiting
usually takes several weeks to develop
administered orally
ex-chlorpromazine
fluphenazine
trifluoperazine
Adverse effects of Phenothiazine
dry mouth, consstipation, visual disturbances and seddation
-reduce blood pressure and postural hypotension
-affect the bascal ganglia and cause movement disorder-EPS dystonic reactions akathisa parkinsonism tardive dyskineasia neuroleptic malignant syndrome
drug allergies that can cause skin rashes, photo sensitivity, blood disorders, and liver toxicity
skin pigmentation, ocular deposits, and endocrine disturbances
