What is the primary purpose of administering entacapone?

• A. To enhance dopamine receptor activity
• B. To prolong the action of levodopa
• C. To reduce side effects of dopamine agonists
• D. To inhibit MAO enzymes

Answer: (B)

The primary purpose of administering entacapone is to prolong the action of levodopa. Entacapone functions as a catechol-O-methyltransferase (COMT) inhibitor, which is important in the management of Parkinson's disease. By inhibiting the COMT enzyme, entacapone prevents the breakdown of levodopa, thereby increasing its bioavailability and extending its therapeutic effects. This is particularly beneficial because levodopa is converted to dopamine in the brain, helping to alleviate the cardinal symptoms of Parkinson's disease such as rigidity, bradykinesia, and tremors. In the context of Parkinson's disease treatment, the use of entacapone alongside levodopa can help minimize the wearing-off effect that patients may experience as their levodopa doses begin to diminish in effectiveness. This improved management of symptoms can lead to a better quality of life for individuals with the condition. Other options, while relevant to the treatment of Parkinson's disease, do not reflect the specific role of entacapone. Enhancing dopamine receptor activity pertains more to other types of medications like dopamine agonists, while reducing side effects of dopamine agonists or inhibiting MAO enzymes involves different pharmacological approaches not directly related to entac
