Antagoists to mu receptors = analgesia, euphoria, resp depression,
sedation, dependance and decresed GI. Agonist to kappa = analges
ia, sedation and decreased GI.
Agonist- antagonist opioids are used for
Mild to mod pain

Abstinence syndrome (cramping, hypertension, and vomiting)
Example of opioid antagonist
Narcan
What is the action of Narcan?
Competes for opioid receptor sites
What is narcan used for?
To reduce effects of opioids such as resp depression, treatment of
opioid overdose

Why are neuromuscular blocking agents used?
Used as adjuncts to general anesthesia to promote muscle relaxatio
n. Used to control spontaneous resp movements in clients on the ve
nt.
Succinylcholine is the preferred agent for (3)
Seizure control during electroconvulsive therapy, ET intubation, end
oscopy
Side effects of succs
Low pseudocholinesterase leads to apnea, malignant hypothermia,
hyperkalemia and after 12-24 hours post op may result in muscle p
ain in upper body and back.
Med/food interactions for neuromuscular blocking agents
General anesthesia, aminoglycosides, tetracycline, neostigmine and
other cholinesterase inhibitors.
Examples of dopaminergics
Levodopa, Sinmet, Levodopa Carbidopa
What does Levadopa do?
Crosses blood brain barrier and is taken up by dopaminergic nerve
terminals and is converted to dopamine. DA is then released into sy
naptic space and causes stim of DA receptors.
What does carbidopa do?
Inhibits conversion of levadopa to DA in intestine and periphery and
allows more levadopa to reach the CNS.
Examples of Dopamine agonists
Mirapex, Requip, Parlodel

What do dopamine agonists do?
Act directly on DA receptors
Examples of centrally acting muscle relaxants
Valium (Diazepam) Baclofen Flexeril Skelaxin
Action of centrally acting muscle relaxants
Acts in the CNS to enhance GABA and produce sedative effects
Examples of peripherally acting muscle relaxants
Valium Baclofen Dantrium
Action of peripherally acting muscle relaxants
Depresses spacticity
What are side effects of lidocaine?
Spinal headaches and urinary retention
Action of clozaril, risperdal, zyprexa, seroquel, abilify
Blocks serotonin and dopamine receptors. Also blocks receptors for
norepi, histamine, and acetylcholine.
