39
Q

Trihexyphenidyl Brand

40
Q

Amantadine brand class, use, side effects

A

Symmetrel
NMDA receptor antagonist
Primarily tremor, mild symptoms
Not in older pts due to renal elimination and CNS effects
SE: dizziness, sedation confusion, vivid dreams, delirium

41
Q

DA replacement + Selegiline or Rasagiline

A

Selegiline: extends the interval of levodopa and can actually lead to a 25% reduction in dose
Rasagiline: gives an extra hour of “on” time

42
Q

DA replacement + DA agonists

A

DA agonists improve the response to levodopa and decrease “wearing off” and “freezing” (motor complications)

43
Q

DA replacement + DA agonist + COMT inhibitor

A

COMT- Extends the duration of levodopa and can reduce the dose so good for motor complications

44
Q

COMT drugs

Entacapone

Tolcapone
