Which medication will affect the activity of any drug utilizing the cytochrome p450 enzyme system?

• A. Selegiline
• B. Benztropine
• C. Entacapone
• D. Ropinirole

Answer: (D)

Cytochrome P450 enzymes handle the metabolism of a wide range of drugs. When a medication is processed by these enzymes, it can compete with or influence the metabolism of other drugs that use the same enzyme, changing how quickly they are cleared and how strong their effects are. Ropinirole is mainly broken down by CYP1A2. Because it relies on this enzyme, it can affect the activity of other drugs that are also metabolized by CYP1A2 through competitive interaction at the enzyme. The other medications listed do not primarily modulate or rely on the CYP450 system in the same way, so they are less likely to alter the activity of other drugs metabolized by CYP enzymes.
