Study Notes
Antipsychotic Drugs Overview
- Typical antipsychotic drugs primarily target dopamine neurotransmitters, specifically D2 receptors.
- Atypical antipsychotics are noted for having increased efficacy for negative symptoms of schizophrenia, which include lack of emotion and motivation.
Tardive Dyskinesia (TD)
- Symptoms of Tardive Dyskinesia may include involuntary movements, facial grimacing, and tongue movements.
- Tardive Dyskinesia is characterized by abnormal, repetitive movements that can occur as a long-term effect of antipsychotic use.
Neuroleptic Malignant Syndrome (NMS)
- The onset period for Neuroleptic Malignant Syndrome can develop within days to weeks after initiation of antipsychotic medication.
- NMS is a potentially life-threatening condition marked by muscle rigidity, fever, and autonomic instability due to dopamine receptor blockade.
Antipsychotic Efficacy and Side Effects
- Clozapine is considered a first-line treatment for treatment-refractory schizophrenia but is associated with the risk of agranulocytosis, a potentially serious decrease in white blood cells.
- Aripiprazole is recognized for having the least metabolic syndrome effects and may lead to fewer extrapyramidal symptoms compared to other antipsychotics.
Compliance and Safety in Treatment
- Long-acting injectable antipsychotics can enhance treatment compliance by reducing the risk of unintentional or intentional overdose due to their sustained release formulations.
- These medications mitigate the risks associated with oral formulations, which may be improperly taken by patients.
