Format: Q&A Guide with Clinical Rationale | Evidence-Based Practice | Verified Accurate Solutions
Instructions: Each question includes the verified correct answer and a detailed clinical pharmacology rationale
covering neurology, psychiatry, endocrinology, men's/women's health, and infectious disease.
1: What adverse effect of dopamine agonists for Parkinson's disease should patients be educated about?
Correct Answer: May cause excessive daytime sleepiness in 50% of PD patients; sudden sleep attacks are
potentially dangerous during driving.
1. Dopamine agonists (pramipexole, ropinirole) can cause sudden onset of sleep without warning.
2. Patients must be advised not to drive or operate heavy machinery until they know how the medication affects them.
3. Risk persists throughout treatment; report any episodes of daytime sleepiness.
2: What is the most effective medication for Parkinson's disease (PD)?
Correct Answer: Levodopa, a dopamine precursor, is the most effective medication for PD. Patients
experience approximately 50% improvement in motor function with levodopa compared to 30% with
dopamine agonists.
1. Levodopa crosses blood-brain barrier and converts to dopamine, replenishing depleted striatal dopamine.
2. Combined with carbidopa to prevent peripheral metabolism and reduce side effects.
3. Long-term use associated with motor fluctuations and dyskinesias; initiate at lowest effective dose.
3: What is the effect of food and medications on levodopa absorption?
Correct Answer: Increased gastric acid, food, or anticholinergic medications delay gastric emptying and
decrease levodopa absorption. Antacids improve absorption whereas iron products bind levodopa and
reduce bioavailability.
1. High-protein meals compete with levodopa for intestinal absorption and blood-brain barrier transport.
2. Take levodopa on empty stomach (30-60 minutes before meals) for optimal absorption.
3. Separate iron supplements by at least 2 hours.
4: What are MAO-B inhibitors and their benefits in Parkinson's disease?
Correct Answer: MAO-B inhibitors (rasagiline, selegiline) are recommended for treatment of PD in
conjunction with levodopa to inhibit dopamine breakdown in the brain, increasing levodopa effect.
Combining with levodopa in early treatment may delay motor complications. Neuroprotection is an
additional benefit when initiated early.
1. Selective MAO-B inhibitors have fewer dietary tyramine restrictions than nonselective MAOIs.
2. Selegiline should not be combined with SSRIs due to serotonin syndrome risk.
3. May allow levodopa dose reduction and reduce "off" time.
5: What is amantadine (Symmetrel) used for in Parkinson's disease?
Correct Answer: Amantadine is an NMDA-receptor antagonist that blocks glutamate transmission,
promotes dopamine release, and blocks acetylcholine. Effective as monotherapy and adjunct therapy for off
time and dyskinesias; extended-release version (Gocovri) is FDA-approved specifically for dyskinesias in
PD.
1. Only approved option specifically for levodopa-induced dyskinesias.
2. Antiviral properties but used primarily for motor symptoms in PD.
3. Side effects: livedo reticularis, ankle edema, confusion (especially in elderly).
, 6: Which medication is the most effective for Parkinson's disease - true or false: Dopamine agonists are the most
effective medications for PD?
Correct Answer: False. Levodopa, a dopamine precursor, is the most effective medication for PD. Patients
experience approximately 50% improvement in motor function with levodopa compared to 30% with
dopamine agonists.
1. Levodopa remains gold standard for symptomatic treatment of PD.
2. Dopamine agonists are effective but less potent; used as initial therapy in younger patients to delay levodopa-related
complications.
3. Combination therapy often used in advanced disease.
7: Combining which medications with levodopa in early treatment may delay motor complications?
Correct Answer: MAO-B Inhibitors (rasagiline, selegiline).
1. MAO-B inhibitors reduce dopamine metabolism, providing more stable dopaminergic stimulation.
2. May allow lower levodopa doses and reduce risk of dyskinesias.
3. Clinical trials suggest neuroprotective properties, though not definitively proven.
8: What is dopamine dysregulation syndrome (DDS) and how does it manifest?
Correct Answer: Impulse control disorder (compulsive gambling, hypersexuality, binge eating,
compulsive shopping, punding).
1. Associated with dopamine agonist use more than levodopa.
2. Patients may take excessive medication doses despite dyskinesias.
3. Screen regularly for impulse control disorders; reduce or discontinue dopamine agonists if symptoms develop.
9: What is the therapeutic goal for patients with Parkinson's disease?
Correct Answer: Symptom management. No drugs prevent neuronal damage or reverse damage; drugs can
only provide symptomatic relief, not cure PD.
1. Treatment focuses on maintaining quality of life and functional independence.
2. Multidisciplinary approach including physical, occupational, and speech therapy.
3. Advanced options: deep brain stimulation for refractory symptoms.
10: How should the family understand the pharmacological approach to symptom management in PD?
Correct Answer: Medications increase dopamine levels and decrease acetylcholine levels in CNS;
responses can take several months to occur. Treatment restores functional balance between dopamine and
acetylcholine using dopaminergic agents and anticholinergic agents.
1. PD results from dopamine deficiency and relative acetylcholine excess.
2. Anticholinergics (benztropine) more effective for tremor than bradykinesia.
3. Realistic expectations: improvement not cure.
11: What effect does carbidopa have on levodopa therapy?
Correct Answer: Carbidopa reduces cardiovascular responses to levodopa. By reducing peripheral
dopamine production, carbidopa reduces cardiovascular responses (hypotension) as well as nausea and
vomiting.
1. Carbidopa does not cross blood-brain barrier; prevents peripheral conversion of levodopa to dopamine.
2. Allows more levodopa to reach brain and reduces peripheral side effects.
3. Standard combination: carbidopa/levodopa (Sinemet).
