Study Notes
Galantamine
- May augment the action of acetylcholine at nicotinic receptors in the CNS.
- Provides a modest reduction in the rate of loss of cognitive functioning in Alzheimer patients.
Rivastigmine
- Only agent approved for the management of dementia associated with Parkinson’s disease.
- Only AChE inhibitor available as a transdermal formulation.
- Should be used with caution in patients with PD.
### Treatment Strategy
- Symptoms of parkinsonism reflect an imbalance between excitatory cholinergic neurons and the greatly diminished number of inhibitory dopaminergic neurons.
CNS Neurotransmission
- Unlike the peripheral ANS, the CNS contains powerful networks of inhibitory neurons that are constantly active in modulating the rate of neuronal transmission.
- CNS communicates through the use of multiple neurotransmitters, whereas the ANS uses only two primary neurotransmitters, acetylcholine and norepinephrine.
- Receptors at most synapses in the CNS are coupled to ion channels.
- Devastating illnesses in the CNS are characterized by the progressive loss of selected neurons in discrete brain areas ( neurodegeneration), resulting in characteristic disorders of movement, cognition, or both.
