Which of the following statements best describes the effect of Donepezil on Alzheimer’s disease?
Donepezil cures Alzheimer's disease
Donepezil prevents the progression of Alzheimer’s disease
Donepezil reverses Alzheimer’s disease
Donepezil provides symptom relief for Alzheimer’s disease
The Correct Answer is D
A. Donepezil cures Alzheimer's disease: There is currently no cure for Alzheimer's disease. Donepezil does not halt or reverse the disease process; it only manages symptoms for a limited period in some patients.
B. Donepezil prevents the progression of Alzheimer’s disease: Donepezil does not prevent the neurodegenerative progression of Alzheimer’s. The disease will continue to advance despite treatment, although symptoms may be temporarily improved.
C. Donepezil reverses Alzheimer’s disease: Alzheimer's-related brain damage is irreversible, and Donepezil cannot regenerate lost neurons or restore lost function. It may slightly improve cognitive function but cannot reverse the disease process.
D. Donepezil provides symptom relief for Alzheimer’s disease: Donepezil is a cholinesterase inhibitor that increases acetylcholine levels in the brain, temporarily improving cognitive symptoms like memory and awareness. It is approved for symptom management, especially in mild to moderate stages.

Correct Answer is B
Explanation
A. Second-generation antihistamines have shorter half-lives and require more frequent dosing compared to first-generation antihistamines: Second-generation antihistamines typically have longer half-lives, allowing once-daily dosing. They are designed for sustained action with improved compliance and fewer side effects.
B. First-generation antihistamines block both histamine and muscarinic receptors, while second-generation antihistamines primarily block histamine receptors: First-generation agents, such as diphenhydramine, cross the blood-brain barrier and exert anticholinergic effects by blocking muscarinic receptors. Second-generation antihistamines are more selective for peripheral H1 receptors, resulting in fewer CNS and anticholinergic side effects.
C. First-generation antihistamines are less likely to cause sedation compared to second-generation antihistamines: First-generation antihistamines are more likely to cause sedation because they easily penetrate the blood-brain barrier and affect central H1 receptors, unlike second-generation agents.
D. Second-generation antihistamines cross the blood-brain barrier, causing significant central nervous system effects: These medications are designed not to cross the blood-brain barrier significantly, which is why they are much less sedating and have minimal CNS effects compared to first-generation antihistamines.
