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.
