Study Notes

Pain Management

Two categories of pain relievers: opioid and non-opioid analgesics
Opioid analgesics: derived from opium, act on opioid receptors in the brain to relieve pain (e.g., morphine)
Non-opioid analgesics: work independently of opioid receptors to relieve pain (e.g., ibuprofen)

Non-Opioid Analgesics

Include over-the-counter drugs (e.g., aspirin, acetaminophen) and some prescription medications
Provide low potential for misuse or withdrawal, but adverse effects can be serious
Act by inhibiting the enzyme cyclooxygenase (COX)

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

Largest class of non-opioid analgesics
Possess analgesic, antipyretic, and anti-inflammatory properties
Common examples include aspirin, ibuprofen, and naproxen
Work by inhibiting prostaglandin synthesis
Well absorbed, metabolized by CYP450 enzymes, and excreted via kidneys

Adverse Effects of NSAIDs

CNS effects: headache, tinnitus, dizziness
Pulmonary effects: higher risk of allergic reactions in asthmatics
Cardiovascular effects: fluid retention, edema, hypertension
Hepatic effects: liver function abnormalities, liver failure
Renal effects: renal insufficiency, renal failure
Gastrointestinal effects: abdominal pain, nausea, vomiting, ulcers
Skin effects: rashes

Non-Selective NSAIDs

Acetylsalicylic acid (aspirin): can be used for mild to moderate pain and fever, helps prevent stroke and myocardial infarctions. Important adverse effect is associated with Reye's Syndrome in children
Ibuprofen: more effective than aspirin in various conditions, clinically useful for closing patent ductus arteriosus in preterm infants, and postoperative dental pain; works by reversibly inhibiting COX-1 and COX-2 enzymes.
Naproxen: most recent addition to over-the-counter analgesics, used for rheumatic conditions, and available as an ophthalmic solution and topical preparation; works by reversibly inhibiting COX-1 and COX-2 enzymes.

Selective NSAIDs

Diclofenac: available by prescription primarily for ophthalmic preparations.
Celecoxib: more selective for COX-2 than COX-1, clinically used for pain and inflammation caused by arthritic conditions.
Meloxicam: preferentially inhibits COX-2.

Other Non-Prescription Drugs: Acetaminophen

Aka Tyleenol or Paracetamol, used as an analgesic and antipyretic
Not an NSAID; differs significantly in mechanism of action, inhibiting prostaglandin formation
Can cause liver injury in overdose or over prolonged use
Mechanism involves the inhibition of COX-1 and COX-2 prostaglandin formation.

Opioid Analgesics

Derived from opium poppy
Alleviate pain for millennia
Examples include morphine and codeine; considered valuable in pain management, with known potential for addiction, use disorders, and withdrawal symptoms.

Opioid Receptors

Mu (μ) receptors involved in pain suppression, respiratory depression, and euphoria, associated with the majority of opioid effects.
Kappa (κ) receptors involved in analgesia and dysphoria.
Delta (δ) receptors also involved in analgesia, are associated with various opioid mechanisms.

Short-Term Effects of Opioids

Analgesia (pain relief)
Sedation
Endocrine effects
Suppression of cough
Miosis (constriction of pupils)
Respiratory depression

Therapeutic Uses of Opioid Drugs

Relief of severe pain
Treatment of diarrhea
Suppression of cough
Treatment of opioid use disorder

Opioid Use Disorder

Tolerance, withdrawal, and addiction can develop.
Cross-tolerance to other opioid analgesics occurs.

Neonatal Drug Withdrawal and Opioid Overdose

Neonatal drug withdrawal may occur in infants exposed to opioids during pregnancy, associated with symptoms such as irritability, sleep disturbance, and feeding problems.
Opioid overdose results in significant respiratory depression, potential for fatality, requiring immediate medical intervention.

Opioid Overdose and Treatment

Overdose results in profound respiratory depression, poses a medical emergency.
Treatment includes opioid antagonists such as naloxone for reversing respiratory depression. Other management includes support of respiration and other essential functions.

Treatment of Opioid Use Disorder

Preferred first-line treatment is buprenorphine/naloxone
Buprenorphine is a partial mu (μ) receptor agonist, preventing withdrawal symptoms while minimizing euphoric effects.
Methadone is a second-line treatment, a long-lasting synthetic opioid.
