o As you begin to learn about these prototype drugs, always consider the following
questions:
1. Why is this drug useful as therapy for a specific condition?
2. How does this drug work to achieve its intended response?
3. What critical actions and assessments should be done before and after administering
this drug?
- Allergies

4. Which points must be highlighted when teaching clients about this drug?
* Strategies for Learning Medications

* Remember
o Almost all neuro pharmacologic drugs work by altering synaptic transmission.
o The end result of synaptic transmission is an alteration in behavior of the postsynaptic, or
target cell.
, o The impact of a drug on a nervous system process depends on that drug's ability to
directly or indirectly alter receptor activity on target cells.
o Drugs can do one of two things to receptor function:
• A- they can increase receptor activation (Agonist) or
• B- they can decrease receptor activation (Antagonist).
o The presence of multiple receptor types increases our ability to produce selective drug
effects.
* Remember
o Agonist Drugs INCREASE receptor activation
▪ Drugs that...
- Increase transmitter synthesis
- Promote "super" transmitters
- Promote transmitter release
- Enhance the natural transmitter
- Inhibit transmitter degradation
o Antagonist drugs DECREASE receptor activation
▪ Drugs that...
- Decrease transmitter synthesis
- Impede transmitter storage
- Suppress transmitter release
- Block transmitter reuptake
* Consider this
o When studying a disease process consider this….
▪ What is the disease
▪ Nursing considerations
▪ How does it affect an individual's life/family’s life
▪ Pt teaching
▪ Medications
▪ Common Labs/Diagnostics
▪ Anything peculiar about this disease
* Parkinson’s and Alzheimer’s
o Cause a progressive loss of neuron function
o Degenerative disorder of the CNS
o Caused by death of neurons that produce the neurotransmitter dopamine
o Resulting in overactivity of acetylcholine
o S/s:
▪ Tremors
▪ Muscle rigidity
▪ Bradykinesia – Difficulty chewing, swallowing and speaking
▪ Postural instability – Easily lose balance. Fall risk!
* Pharmacotherapy for Parkinson’s
