Biological Therapy Flashcards
What does drug therapy aim to do?
Manipulate a patients bodily processes with the goal of reducing the symptoms of their mental health disorder
What is the first component of drug therapy?
Anti-psychotics
What are the two types of anti-psychotic?
Conventional and Atypical
How do conventional anti-psychotics worK?
They bind to dopamine receptors in the brain and block them without stimulation them which reduces the flow of dopamine in the brain
How do atypical anti-psychotics work?
Similarly to conventional, however only temporarily blocking the dopamine receptors, which will then dissociate and allow for normal flow
What is an example of a conventional anti-psychotic?
Chlorpromazine
What are the side effects to Chlorpromazine?
Tardive Dyskinesia
Drowsiness
Light headedness
What is an example of an atypical anti-psychotic?
Clozarrl
What are the side effects to Clozarrl?
Headache
Drowsiness
Less Tardive Dyskinesia
What is Tardive Dyskinesia?
Irregular involuntary bodily movements
What is the second component of drug therapy?
Anti-depressants
What are anti-depressants also known as?
SSRI’s
How do anti-depressants work?
They bind to post-synaptic receptor sites in the neuron, which stops the reuptake of serotonin therefore less is absorbed. This allows more serotonin to be built up in the synaptic cleft to be available in the brain
What are examples of anti-depressants?
Sertraline and Prozac
What are side effects of Prozac?
Seizures
Confusion
Unusual dreams
What are side effects of Sertaline?
Nausea
Headaches
Insomnia
What is the third component of drug therapy?
Anti-anxiety drugs
What are the two types of anti-anxiety drugs?
Benzodiazepines (BZ’s) and Beta-blockers (BB’s)
How do BZ’s work?
Slows the activity of the central nervous systems (CNS) by enhancing the activity of GABA (stress reliever) e.g. slow heart rate, blood pressure etc.
How do BB’s work?
Binding to the receptors on the cells on the areas of the body that become aroused and blocking them to slow their function e.g. heart rate, blood pressure etc.
What are the side effects of BZ’s?
Slurred speech
Nausea
Muscle weakness
What are the side effects of BB’s?
Cold fingers and toes
Sickness
Tiredness
What are the effectiveness evaluation points of drug therapy?
Research to support
Comparison to other therapies
Treating the symptom not the cause
Side effects
Research against
What are the ethics evaluation points of drug therapy?
Use of placebos
Informed consent
Protection from serious harm
