Study Notes
Headache and Migraine Management
- Indications: Effective for cluster headaches and acute migraine attacks.
-
Contraindications:
- Coronary artery disease (CAD) increases risk of coronary vasospasm.
- Cerebrovascular diseases and conditions like basilar or hemiplegic migraine.
- Ischemic bowel, pregnancy, peripheral vascular disease (PVD).
- Uncontrolled hypertension increases risk.
Ergotamine Derivatives
- Usage Restrictions: Avoid within 24 hours of ergotamine use or within 2 weeks of MAOI usage to prevent vasospasm risks.
-
Adverse Effects (AE):
- Serious: Coronary vasospasm, myocardial infarction (MI), ventricular arrhythmias, subarachnoid hemorrhage, serotonin syndrome.
- Common: Dizziness, nausea, jaw/neck pain, temperature sensations, dry mouth, chest pain, diaphoresis, vertigo.
Ergots Overview
- Source: Derived from the fungus Claviceps purpurea.
- Mechanism of Action (MOA): Inhibits acetylcholinesterase, increasing cholinergic concentrations for enhanced neurotransmission.
- Dose Considerations: Effects are dose-dependent; titration to maximum-tolerated doses recommended.
- Cautions: Potential for dizziness, bradycardia, gastrointestinal (GI) issues, insomnia, and vivid dreams.
-
Drug Interactions:
- Anticholinergics may reduce efficacy of cholinesterase inhibitors.
- Caution when mixed with amiodarone, beta-blockers leading to worsened bradycardia.
- NSAIDs may heighten GI bleed risk.
Anticonvulsants - Carbamazepine
- Indications: Treats various seizure types and mood stabilization.
- MOA: Blocks voltage-gated sodium channels, stabilizing overactive neuronal impulses.
- Contraindications: Severe heart/liver disease, bradycardia, hypersensitivity.
-
Adverse Effects:
- Common: Dizziness, rash, GI symptoms, sedation.
- Serious: Cardiac arrhythmias, CNS effects, GI toxicity.
Succinimides
- Indication: Specifically used for absence seizures characterized by brief episodes of unresponsiveness.
- MOA: Reduces T-Type calcium channel activity in thalamic neurons, preventing hyperexcitability.
- Contraindications: Hypersensitivity and severe liver or kidney impairment.
-
Adverse Effects:
- Common: GI distress, drowsiness, and fatigue.
- Serious: Blood dyscrasias leading to bone marrow suppression, systemic lupus erythematosus (SLE), psychiatric effects.
- Monitoring: Regular CBC and hepatic/renal function tests recommended.
Parkinson’s Disease Treatment
- Pathophysiology: Characterized by progressive loss of dopaminergic neurons leading to tremors, bradykinesia, and motor complications.
-
Dopaminergic Drug Types:
- Levodopa: Converts to dopamine in the CNS, improving motor symptoms but may increase dyskinesias with prolonged use.
- Carbidopa: Inhibits peripheral conversion of levodopa, enhancing CNS delivery and reducing nausea.
- Dopamine Agonists: Directly stimulate dopamine receptors; examples include pramipexole and ropinirole.
COMT Inhibitors
- Function: Prolong the action of levodopa by inhibiting its peripheral breakdown.
- Adverse Effects: Abdominal pain, diarrhea, orthostatic hypotension, and rhabdomyolysis can occur.
General Considerations
- Long-term Risks: Increased risk of dyskinesias with prolonged dopamine treatment.
- Special Precautions: Monitor for side effects across all treatment classes and adjust dosages appropriately based on individual tolerance and response.
