Questions and Answers

Which of the following is a characteristic of non-steroidal anti-inflammatory drugs (NSAIDs)?

  • They induce numbness and loss of consciousness as a side effect.
  • They are also known as narcotics due to their analgesic effects.
  • They have uricosuric effects, decreasing uric acid excretion.
  • They provide weaker anti-inflammatory effects compared to glucocorticoids. (correct)

    • What is the main purpose of using narcotics over NSAIDs?

  • To provide anti-inflammatory effects for rheumatic diseases.

    • What distinguishes the analgesic effects of NSAIDs from narcotics?

  • NSAIDs are known for their uricosuric effects.
  • Narcotics are more effective in reducing inflammation.

    Study Notes

    Analgesics and Antipyretics Summary

    • NSAIDs are preferred in minor musculoskeletal trauma, soft tissue inflammation, superficial surgical intervention, minor gynecological procedures, acute pain of mild to moderate severity, ureteral colic, and dysmenorrhea.
    • There are two types of pain mediators: algesic mediators and hyperalgesic pain mediators, which increase the sensitivity of nerve endings to algesic agents.
    • The analgesic effect of NSAIDs is largely due to their peripheral effects, reducing the synthesis of prostaglandins and preventing pain through anti-inflammatory action.
    • COX enzyme types include COX-1, which has a protective function, COX-2, responsible for pro-inflammatory prostaglandins, and COX-3 present in the central nervous system.
    • Prerequisites for the use of analgesics include understanding the drug's mechanism of action, side effects, drug interactions, and detailed knowledge of doses.
    • The purpose of pain treatment is to produce the strongest analgesic effect with the fewest side effects, optimal dose, and easiest application.
    • An ideal analgesic should be effective when used orally, have a sufficient analgesic effect, not be tolerant or addictive, have a specific effect in the central nervous system, and have an antidote.
    • Antipyretics reduce fever due to infection and inflammation by reducing the synthesis of prostaglandins and increasing heat loss by vasodilation.
    • Situations in which fever needs to be reduced include elderly people with coronary insufficiency, pregnant women, young children with convulsions, and hyperthermia.
    • Medicines that can cause fever include phenothiazine, anticholinergic drugs, and cocaine use, while malignant hyperthermia is characterized by hypermetabolism and muscle rigidity.
    • The mechanisms of anti-inflammatory action of NSAIDs include cyclooxygenase inhibition, reduction in the synthesis of cytokines and active oxygen radicals, and stabilization of lysosome membrane.
    • Physicochemical properties that increase anti-inflammatory activity include weak acidity of both analgesics and their metabolites.

    Summary of Analgesic Drug Groups

    • Profens (phenylpropionic acid derivatives) are a commonly used analgesic drug group after aspirin and paracetamol.
    • Ibuprofen is the most used drug in the profens group, with antipyretic, analgesic, and anti-inflammatory properties.
    • Naproxen, with the longest duration of action, is used for rheumatoid arthritis, osteoarthritis, and mild to moderate pain.
    • Ketoprofen inhibits cyclooxygenase and has analgesic, antipyretic, and anti-inflammatory effects, similar to indomethacin.
    • Flurbiprofen, a profen drug, may cause rigidity, ataxia, tremor, and myoclonus as rare side effects.
    • Tiaprofenic acid is used for osteoarthritis, rheumatoid arthritis, and soft tissue inflammation, but can cause cystitis.
    • Diclofenac sodium is administered via the intramuscular route and has been found effective against rheumatoid arthritis and osteoarthritis.
    • Indomethacin is used for its anti-inflammatory effect and in conditions like ankylosing spondylitis, osteoarthritis, and rheumatoid arthritis.
    • Ketorolac tromethamine is now prohibited due to causing GI bleeding, acute kidney failure, and anaphylactic shock.
    • Sulindac, a prodrug, converts to a sulfur derivative in the liver and has little interaction with antihypertensive drugs.
    • Etodolac is selective for COX-2 at low doses and causes fewer upper GI adverse events in clinical trials.
    • Oxicams and others like piroxicam, tenoxicam, and meloxicam are long-acting analgesics with specific uses and characteristics.
