Psychopharmacology 2 Flashcards
What are antidepressants?
Antidepressants work by balancing chemicals in your brain called neurotransmitters to address deficiencies in key areas of the brain
What is the biomedical explanation for depression?
That depression stems from a deficiency of norepinephrine (NE), dopamins, or serotonin in key areas of the brain.
What are the 3 ways an antidepressant addresses deficiencys in the brain?
- They inhibit the effects of monoamine oxide thus increasing serotonin and norepinephrine in the synaptic cleft
- They block the reuptake of specific neurotransmitters leading to a build up of these in the synaptic cleft
- They are involved in regulation at receptor sites and the breakdown of neurotransmitters
What are some mild symptoms of serotonin syndrome?
Increased heart rate, shivering, sweating, dilated pupils, myoclonus, and over-responsive reflexes.
What do Selective serotonic reuptake inhibitors (SSRIs) and related drugs do? (Antidepressants).
Simply, they are the first line of treatment for depression and have less side-effects than others. Common side effects include: Drowsiness, insomnia, sexual dysfunction, nausea, and vomiting.
What is serotonin syndrome?
Serotonin syndrome is a serious drug reaction. It is caused by medications that build up high levels of serotonin in the body. The onset is often rapid and can be life-threatening
What are the common side effects from Tricyclic antidepressants (TCAs)?
dry mouth, blurred vision, constipation, urinary retention, drowsiness, and weight gain
What are the common side effects from Monoamine oxidase inhibitors (MAOIs)?
Postural hypotension, constipation, drowsiness, dry mouth, fatigue, headache, insomnia, and sexual dysfunction
What are mood stabilisers?
Drugs used for the treatment of bipolar affective disorders and schizo-affective disorders - they may also treat manic episodes
What is the drug of choice for treatment of acute mania and ongoing maintenance?
Lithium
How does Lithium work to treat acute mania?
It mimics the affects of sodium and compromises the ability of neurons to release, activate and respond to neurotransmitters.
What are some common side affects of lithium?
Tremor, stomach upset, polyuria, and polydipsia
What do Anticonvulsants do?
Anticonvulsants work by calming hyperactivity in the brain in various ways (Stabilising nerve membranes throughout the CNS)
What are Anxiolytic (Anti-anxiety) medications?
Anxiolytics are a class of medications used to prevent or treat anxiety symptoms or disorders
What do Benzodiazepines (Anxiolytics) do?
They are sedatives / anxiolytics (relieve anxiety) that act in the limbic system to treat anxiety disorders, agitation, insomnia, muscle spasm, and alcohol withdrawl.
