5
New cards
CNS
Non-narcotic analgesics inhibits prostaglandin production in the ________.
6
New cards

what does the Peripheral Nervous System do

detects temperature, pressure, touch, pain

7
New cards
Sensation
Heat, cold, pressure, or chemical stimulus to sensory receptors and nerve endings in the peripheral nervous system
8
New cards
Pain Receptors
Perceive the sensation of pain when stimulated
9
New cards
Pain
as physically or emotionally sensed discomfort that is associated with acute tissue damage or a sensory system malfunction
10
New cards
how to combination opioids works
by relieving pain both centrally and peripherally
11
New cards
Inflammation
causes a cascade of events that untimely forms prostaglandins
12
New cards

what kind of pain involves bones, muscles and ligamant

nociceptive (Somatic)

13
New cards

what kind of pain involves kidneys, liver and intestines

nociceptive (Visceral)

14
New cards

what kind of pain involves nerve damage

neuropathic

15
New cards

what kind of pain involves dysregulated pain processing in the central nervous system

centralized

16
New cards
Somatic Pain
originates from injury to body tissue
17
New cards
Visceral Pain
originates from problems with internal organs
18
New cards
Neuropathic Pain
from damage of nerve tissue
19
New cards

Patient feels pain when there is no obvious stimulus for it

Sympathetic-mediated pain; centralized

20
New cards
Background pain
describes a constant level of pain
21
New cards
Breakthrough pain
describes when pain of greater intensity occurs intermittently for no particular reason
22
New cards
Provoked pain
describes pain that is more intense than background pain but has a clear cause
23
New cards
dependence
A physical and emotional reliance on a drug; Withdrawal when drug is discontinued or dose is reduced
24
New cards
addiction
Compulsive disorder leading to continued use of drug despite harm
25
New cards
what do nonnarcotic analgesics do
Inhibits prostaglandin production in the CNS
26
New cards
what does aspirin do
inhibits cyclooxygenase, the enzyme that converts arachidonic acid to prostaglandins
27
New cards
anesthesia
an intervention for intentional loss of feeling in a person’s body or part of the body when pain relief, anxiety relief, or muscle relaxation is required for patient care
28
New cards
neuraxial anesthesia
blocks sensation through injection of an anesthetic into the CNS without making the patient unconscious
29
New cards
local anesthesia
is used for local pain reduction
30
New cards
general anesthesia
causes reversible unconsciousness and absence of response to painful stimuli.
31
New cards
what are the most potent anethetics
gases and vapors
32
New cards
malignant hyperthermia
a rare disease; A sudden and rapid rise in body temperature with irregularities in heart rhythm and breathing Fever of __110°F__ or more
33
New cards
what is sufentanil
5-10 times more potent than fentanyl
34
New cards
Name 3 benzodiazepines induction agents
* diazepam (Valium)
* lorazepam (Ativan)
* midazolam
35
New cards
esters
are short-acting and are metabolized by pseudocholinesterase in the plasma
36
New cards
Amides
are longer-acting and are metabolized by liver enzymes
37
New cards
what is a migraine
A severe, throbbing, unilateral headache accompanied by symptoms such as nausea, vomiting, photophobia, phonophobia, hyperesthesia
38
New cards
Aura
Visual or sensory disturbances such as seeing flashing lights; shimmering heat waves; bright lights; dark halos in visual field; blurred, cloudy vision; transient loss of vision
39
New cards
pathophysiology
Dilation of cerebral surface vessels
40
New cards
Caffeine
A CNS stimulant used in combination with other analgesics to treat headache
41
New cards
what is nitrous oxide (N2O) used for
Memory loss, mildly slowed breathing
42
New cards
what is Capsaicin used for
topical pain treatment
43
New cards
Principles of OAT
must be treated with respect and dignity
44
New cards
What is Buprenorphine-Naloxone
therapeutic agent has been shown to be lower risk to patients in terms of safety. The potential for diversion exists however overdose is less likely to be fatal.

\
45
New cards
what is Sustained Release Oral Morphine (SROM)
Due to the risks of toxicity associated with bolus absorption and diversion, extra safeguards need to be in place and are referred to in the NBCP directive.
46
New cards
what is iOAT
not considered first line of therapy, however, injectable hydromorphone is a newer agent considered for use in OUD. It is considered to have high potential for diversion and risk to patient outcomes
47
New cards
**Dispensing documentation**
Pharmacists and pharmacy technicians must document each step in dispensing of OAT. Given that medication used in OUD may require dilution, and that the agents are desirable for purposes of diversion, the documentation required is greater than that required for dispensing of typical (non-OAT) oral dosage forms
48
New cards
Clinical Documentation
Pharmacists must document patient assessment. Pharmacists or pharmacy technicians must document follow-up of patients for observed dosing or take-home dispensing
49
New cards
* **College documentation**
The COllege must know who is providing OAT
50
New cards
what is a carry audit
they may be asked at any time to appear in the pharmacy and bring with them the remainder of their take-home doses and empty bottles, in their own lock box.
51
New cards
SROM
To limit potential for diversion, slow-release oral morphine is only to be provided via daily observed ingestion
52
New cards
iOAT
To limit potential for diversion and encourage safe injection technique, iOAT is only to be provided via daily observed self-administration in accordance with policy and practice guidelines
53
New cards
E**ducation and Training Documentation**
Pharmacy professionals must document within the pharmacy’s QMP that they have established and maintained competency for providing OAT for patients with OUD
