Analgesics
1. Drug Classes
3. Nonopioid Analgesics
Medications used to treat pain are either
Nonopioids inhibit prostaglandin synthesis
nonopioid, opioid, or adjuvant analgesics:
Block pain and fever signals in the central or
1. Nonopioid analgesics: peripheral nervous systems (CNS or PNS)
For mild to moderate pain Medications (see TABLE 3):
Most are available over the counter
(OTC). Acetaminophen (works in the CNS)
Treats pain and fever
2. Opioid analgesics:
Aspirin and other NSAIDs (work in the PNS)
For moderate to severe pain
Treat pain, fever, and inflammation (e.g.,
Have potential for tolerance,
from arthritis, sprains)
dependence, and abuse
Aspirin has additional antiplatelet effects
3. Adjuvant drugs: and is used to prevent stroke and MI.
Medications from other classes that also
have analgesic properties (e.g., 4. Acetaminophen
antidepressants, muscle relaxants).
FIGURE 1. ACETAMINOPHEN AT A GLANCE
2. Nursing Considerations
For better pain control with fewer adverse
effects,
alternate analgesics from different classes.
Pain is easier to prevent than to treat:
Premedicate before painful procedures
(wound care, physical therapy).
Treat chronic pain with scheduled
analgesics given around the clock rather
than Acetaminophen (FIGURE 1):
“as-needed” only. Preferred analgesic in clients at risk for

6 hours around the clock plus IV Has no anti-inflammatory effects

nonpharmacologic interventions (ice, heat). Monitor forin liver enzymes (AST, ALT, ALP).
Never administer a placebo (like saline) for pain.
, Avoid acetaminophen in clients with liver disease or alcoholism due to the risk for hepatotoxicity.
