Dopamine Agonists: Mimicking Dopamine
Dopamine agonists trick the brain into thinking it's receiving dopamine. They can be used early in the disease or later to complement levodopa. Common options include pramipexole, ropinirole, and rotigotine patches. While generally less potent than levodopa, they may have a lower risk of causing dyskinesias.
MAO-B Inhibitors: Preserving Dopamine
These medications, such as selegiline and rasagiline, work by blocking an enzyme that breaks down dopamine in the brain. This helps preserve the brain's natural dopamine and can enhance the effects of levodopa. They're often used in early Parkinson's or as an add-on therapy.
Amantadine: Multi-Purpose Helper
Amantadine has a unique role in Parkinson's treatment. It can be used early in the disease to help with symptoms, particularly tremor. Later on, it's often used to help manage dyskinesias caused by long-term levodopa use. Its exact mechanism isn't fully understood, but it appears to affect multiple brain systems.
