Selegiline is used alone or in conjunction with __________ in the early stages of the disease to help with symptom fluctuations.

Explanation:
Selegiline works by inhibiting MAO-B, which slows the breakdown of dopamine in the brain. In the early stages of Parkinson’s, fluctuations in response to levodopa (wearing-off) can develop. Adding selegiline to carbidopa-levodopa helps sustain dopamine levels for a longer period, improving motor control and reducing fluctuations. This combination is a common strategy to enhance and extend the effect of levodopa, making symptoms more stable. Rasagiline is another MAO-B inhibitor but isn’t the pairing described here; entacapone is a COMT inhibitor that can extend levodopa’s effect, and levodopa is the therapy whose benefit is amplified by selegiline.
