-azine
Haloperidol, Trifluoperazine, Fluphenazine, Chlorpromazine, Thioridazine
1. What kind of drugs are these?
2. MOA
- First generation anitpsychotics
- Blocks D2 receptors in CNS - mesolimbic system
in psychotic disorders what are the levels of dopamine in
1. mesolimbic system
2. mesocortical system
- increased
- decreased
Typical/First generation antipsychotics
1. High potency means what type of binding on D2 receptors + what generalized side effects
2. Low potency means what type of binding on D2 receptors + what generalized side effect
- high potency -> greater D2 receptor binding -> more extrapyramidal effects (motor)
- low potency -> less D2 receptor binding but more histamine and muscarinic binding -> leading to sedation and anti-cholinergic effects
What are Typical and Atypical Antipsychotics used for? (5)
- Schizophrenia (typical antipsychotics primarily treat positive symptoms; atypical antipsychotics treat both positive and negative symptoms)
- Disorders with concomitant psychosis (eg, bipolar
disorder) - Tourette syndrome
- OCD
- Huntington disease.
What are side effects of low potency typical/first generation antipsychotics?
- anticholinergic effects
- Orthostatic hypotension (alpha 1 block)
- Sedation (H1 block)
- Chlorpromazine can cause corneal deposits
- Thiordazine can cause retinal deposits
What are side effects of high potency typical/first generation antipsychotics?
- extrapyramidal symptoms (EPS) - ADAPT (acute dystonia, akathisia, parkinsonism, tardive dyskinesia)
- hyperprolactinemia
- Neuroleptic malignant syndrome (NMS) - generalized rigidity, fever, rhadbdomyolysis
