Parkinson's Disease: Pharmacology and Therapy Quiz

Which type of drugs are used to treat Parkinson's disease?

• Dopaminergic drugs

• Antibiotics

• Antihistamines

• Beta-blockers

What is the main imbalance in the motor pathways in Parkinson's disease?

• Too much Ach and not enough Dopamine

• Too much Dopamine and not enough Ach

• Equal levels of Ach and Dopamine

• Too much Serotonin and not enough Dopamine

What is the primary goal of therapy for Parkinson's disease?

• To increase or enhance the action of dopamine in the brain

• To decrease serotonin levels

• To increase acetylcholine levels

• To reduce blood pressure

Which agents are used to inhibit the action of Ach in Parkinson's therapy?

• Anticholinergic agents

• Antibiotic agents

• Antihistamine agents

• Beta-adrenergic agents

What is the result of inhibiting the action of Ach in Parkinson's therapy?

• Restoring the balance between dopamine and Ach

• Increasing serotonin levels

• Decreasing dopamine levels

• Increasing blood pressure

Why can't dopamine itself be used directly to treat Parkinson's disease?

• It cannot cross the blood-brain barrier

• It is too expensive

• It causes severe allergic reactions

• It is not effective in the body

What is used to replace lost dopamine or enhance what remains in the brain?

• Exogenous dopamine

• Serotonin inhibitors

• Antibiotics

• Beta-blockers

Where do dopaminergic drugs increase the effects of dopamine?

• At receptor sites in substantia nigra

• In the liver

• In the heart

• In the lungs

What do dopaminergic brain structures facilitate?

• Dopamine related activity

• Serotonin production

• Acetylcholine breakdown

• Blood pressure regulation

For how long are dopaminergic drugs effective in treating Parkinson's disease?

• As long as intact neurons remain in the substantia nigra

• For a lifetime regardless of neuron health

• Only for one week

• Only in children
