Pain and Inflammation Management Agents Flashcards
Phases of Inflammation
Vascular phase
Delayed phase
a reaction to tissue injury caused by the release of chemical mediators that trigger both a vascular response and the migration of fluid and cells to the injured site
Inflammation
occurs 10-15 minutes after an injury
Vascular phase
vasodilation and increased capillary permeability 🡪 fluid shift to the injured site
Vascular phase
leukocytes infiltrate the inflamed tissue
Delayed phase
Chemical Mediators
Histamine
Kinin
Prostaglandin
first mediator
Histamine
causes dilation of the arterioles and increases capillary permeability 🡪 fluids shift to the injured area
Histamine
-increase capillary permeability and the sensation to pain
Kinins
increase in vasodilation, capillary permeability, pain, and fever
Prostaglandins
Antiinflammatory Agents aka
Prostaglandin Inhibitors
Relieve pain, reduce elevated body temperature, and inhibit platelet aggregation
Antiinflammatory Agents
Oldest anti-inflammatory drug
ASPIRIN
First used as analgesic and antipyretic
ASPIRIN
Aspirin and aspirin-like drugs that inhibit the COX enzyme
NONSTEROIDAL ANTIINFLAMMATORY DRUGS
Not suggested for use in alleviating mild headaches and mildly elevated temperature
NONSTEROIDAL ANTIINFLAMMATORY DRUGS
More appropriate for reducing swelling, pain, and stiffness in joints
NONSTEROIDAL ANTIINFLAMMATORY DRUGS
only OTC NSAIDs
Ibuprofen and naproxen
1st generation
- Salicylates
- Para-chlorobenzoic acid derivatives/ indoles
- Phenylacetic acids
- Propionic acid derivatives
- Fenamates
- Oxicams
Aspirin aka
acetylsalicylic acid (ASA)
Also considered as an antiplatelet drug for patients with cardiac or cerebrovascular disorders
Aspirin
a rare disorder that typically occurs after a viral illness that results in brain and liver damage.
Reye’s Syndrome
The proposed mechanism for aspirin contributing to the development of Reye’s syndrome is related to __________________________ that can be caused by salicylates, which may be intensified during viral illness by endotoxins and cytokines
mitochondrial damage
- used for rheumatoid arthritis, gouty arthritis an osteoarthritis
- potent prostaglandin inhibitor
- 90% protein-bound
- very irritating to the stomach, should be taken with food
Indomethacin
Similar to the analgesic and anti-inflammatory effects of aspirin, but minimal to no antipyretic effects
Diclofenac
first injectable NSAID
Ketorolac
used acute and chronic arthritis
Meclofenamate sodium and Mefenamic acid
