Study Notes
Analgesics Overview
- Analgesics are medications that relieve pain without inducing loss of consciousness.
- They function through multiple mechanisms to reduce or block pain sensations.
Classification of Analgesics
- Non-opioid analgesics: Include NSAIDs and acetaminophen (paracetamol).
- Opioid analgesics: Another class not detailed in this segment.
- Adjuvant analgesics: Additional supportive medications included but not elaborated here.
Non-opioid Analgesics
- Primarily composed of NSAIDs and acetaminophen.
NSAIDs
- Used to manage pain, fever, and inflammation.
Classification of NSAIDs:
-
Non-selective COX inhibitors:
- Include aspirin, diclofenac, etodolac, flurbiprofen, ibuprofen, indomethacin, ketoprofen, ketorolac, mefenamic acid, meloxicam, and naproxen.
-
Selective COX-2 inhibitors:
- Celecoxib and etoricoxib.
Mechanism of Action:
- NSAIDs work by inhibiting prostaglandin synthesis through non-selective inhibition of COX-1 and COX-2 enzymes, decreasing inflammation and pain.
Indications for NSAIDs:
- Effective for muscle pain, dysmenorrhea, arthritis, fever, gout, and migraine relief.
Adverse Effects:
- Possible side effects include gastrointestinal ulcers, peripheral edema, myocardial infarction, gastrointestinal bleeding, and bronchoconstriction.
Contraindications:
- Should be avoided in individuals with NSAID hypersensitivity, urticaria, asthma, recent CABG surgery, and during the third trimester of pregnancy.
Drug-Drug Interactions:
- Potential interactions with ACE inhibitors, ARBs, anticoagulants, and corticosteroids.
Acetaminophen (Paracetamol)
- An over-the-counter drug used for pain relief (analgesic) and fever reduction (antipyretic).
Mechanism of Action:
- The precise mechanism remains unclear, but it inhibits cyclooxygenase (COX) pathways, similar to NSAIDs.
