Anipryl works by inhibiting monoamine oxidase B in the brain. MAO-B's job is to break down dopamine, so blocking this enzyme increases dopamine availability in dopaminergic pathways. In Canine Cognitive Dysfunction Syndrome, boosting dopamine helps improve cognition and activity, making this mechanism particularly effective. At therapeutic doses, the drug is relatively selective for MAO-B, which means it mainly enhances dopamine with fewer issues related to other monoamines. The other options relate to different targets (acetylcholine, glutamate, or amyloid processing) and do not describe how Anipryl works.
