Multiple Choice

Selegiline is given to __________ the needed dose of levodopa.

Explanation:
Selegiline works by slowing the breakdown of dopamine in the brain. It is a monoamine oxidase-B inhibitor, so when you give it with levodopa, the dopamine released from levodopa lasts longer. That means you can achieve the same motor control with a lower dose of levodopa, which is why the needed dose is decreased. This also helps reduce wearing-off and fluctuations. (Note: MAO-B inhibition is selective at typical doses, but always be mindful of potential interactions with other drugs or foods at higher doses.)
