Study Notes
Symptoms of Schizophrenia
- Hallucinations, delusions, and disorganized thinking are hallmark symptoms.
- Cognitive impairments and negative symptoms like lack of motivation and social withdrawal may also occur.
Maintenance Dose of Haloperidol
- Recommended maintenance dose varies but typically ranges from 5 to 20 mg/day for severe cases.
Mechanisms of Action of Classical Antipsychotics
- Primarily block dopamine D2 receptors in the brain.
- Modulate neurotransmission pathways to alleviate psychotic symptoms.
Adverse Effects of Antipsychotics
- Common adverse effects include sedation, weight gain, and anticholinergic effects.
- Extrapyramidal symptoms (EPS) such as tremors, rigidity, and tardive dyskinesia can occur with prolonged use.
Endocrine Effects of Antipsychotics
- May cause hyperprolactinemia leading to menstrual irregularities and galactorrhea.
- Weight gain can contribute to metabolic syndrome.
Instructions for Outdoor Activities
- John should practice sun protection and hydration, as some medications increase sensitivity to sunlight.
Motor Disturbances to Monitor
- Monitor for tremors, dystonia, akathisia, and tardive dyskinesia due to long-term antipsychotic use.
Possible Causes of Schizophrenia
- Genetic predisposition, environmental triggers, and neurodevelopmental factors may contribute to the onset.
Side Effects of Antischizophrenic Medications
- Potential side effects include sedation, dry mouth, and blurred vision.
Formulations of Antischizophrenic Medications
- Available preparations include oral tablets, liquid formulations, and long-acting injectable depot forms.
Advantages of Depot Injections
- Enhance compliance by reducing the frequency of administration.
- Provide stable plasma levels, minimizing the risk of relapse.
Assessment Before Prescribing Antidepressants
- The GP should evaluate potential contraindications, history of manic episodes, and any current medications to prevent interactions.
Adverse Reactions of SSRIs
- Common adverse reactions include gastrointestinal disturbances, sexual dysfunction, and insomnia.
Instructions for Managing Insomnia with Medication
- Georgia should be advised on relaxation techniques and to avoid taking medications close to bedtime to enhance sleep quality.
Symptoms of Serotonin Syndrome
- Symptoms may include agitation, confusion, rapid heart rate, and muscle rigidity.
Cause of Serotonin Syndrome
- Occurs due to excessive serotonergic activity, often from drug interactions or overdose.
Conditions Increasing Risk of Serotonin Syndrome
- Co-occurring use of multiple serotonergic drugs (e.g., SSRIs, SNRIs, or MAOIs) raises the risk.
Medications Precipitating Serotonin Syndrome
- Other medications like tricyclic antidepressants, certain anti-migraine medications, and some opioids can trigger the condition.
Advice for Increasing Serotonin Levels
- Users should be monitored for signs of serotonin syndrome and advised to communicate any symptoms to healthcare providers.
Class of Antidepressant Medications
- SSRIs, SNRIs, and atypical antidepressants are common classes listed.
Possible Causes of Unipolar Depression
- Life stressors, genetic factors, and chemical imbalances in the brain may contribute to unipolar depression.
Drugs Not Found in Heath Ledger's System
- Specific details on which drugs were not present are necessary for clarity.
Class of Drugs for Temazepam
- Temazepam belongs to the benzodiazepine class, used primarily for insomnia.
Common Anti-Anxiety Medication
- Benzodiazepines, such as diazepam and lorazepam, are widely used for anxiety relief.
Mechanism of Action of Oxycodone
- Oxycodone acts as an opioid analgesic, binding to mu-opioid receptors in the brain to relieve pain.
Indications for Hydrocodone
- Used for moderate to severe pain management and often in combination with acetaminophen.
Common Side Effect Across Drugs in Ledger's System
- Sedation or respiratory depression is a common side effect associated with opioids and benzodiazepines.
Multiple Prescription Medications
- Prescriptions for various medications with similar effects can sometimes occur due to lack of communication between healthcare providers.
Prevention of Multiple Prescription Medications
- Implementing comprehensive patient medication reviews and a centralized electronic health record system can help prevent this issue.
Alternative Treatments for Insomnia
- Cognitive-behavioral therapy for insomnia (CBT-I), lifestyle modifications, and mindfulness techniques are effective alternatives.
