LAB_Anti-Inflam and Analgesics Flashcards
a response intended to eliminate the initial cause of cell injury,
remove the damaged tissue, and generate new tissue
Inflammation
Cardinal signs of inflammation:
- rubor (redness)
- tumor (swelling)
- calor (heat)
- dolor (pain)
- functio laesa (loss of function)
Materials needed for inflammatory activity
- Plethysmometer
- Tuberculin syringes
- Intubation needles
- Individual Observation Cages
- 24 or 26 gauge 1” syringes
Anti-inflamm drugs
Diclofenac
Carrageenan
It is a highly sensitive and reproducible test for nonsteroidal antiinflammatory drugs and has long been established as a valid model to
study new anti-inflammatory drugs
Carrageenan-Induced Paw Edema
The development of edema induced by carrageenan injection causes
an _____ and ______ inflammatory response
acute and local
In the early phase (0-1h), ________, ________, and _________ are
the first mediators involved
histamine, serotonin, and bradykinin
In the second phase - ________ and various _______ such as
IL-1β, IL-6, IL-10, and TNF-α are implicated
Prostaglandins ; cytokines
Used to suppress the symptoms of inflammation and relieve pain
(analgesic action) and fever (antipyretic action)
Non-Steroidal Anti-inflammatory Drugs
(NSAIDS)
Anti-inflammatory effect of nsaids:
inhibition of COX-1 and COX-2
NSAID that inhibits COX-1 and COX-2
Aspirin
Inhibit COX-2>COX-1
COX-2 selective agents
_____ reduce the inflammatory response and pain but not the cytoprotective action of
prostaglandins in the stomach
COX-2
Analgesic effect of NSAIDs
Inhibition of PGE2 and PGI2
: inhibition of production of prostaglandins induced by IL1 and IL-6 in the hypothalamus and the ‘resetting’ of the thermoregulatory
system leading to vasodilation and increased heat loss
Antipyretic effect of NSAIDs
First-line drugs to arrest inflammation and accompanying pain of
rheumatic and non-rheumatic diseases
NSAIDs
NSAIDs alleviate __________ pain
mild-moderate
T/F: NSAIDs reduce elevated body temperature
T
Ibuprofen, fenoprofen, ketoprofen flurbiprofen, oxaprozin, naproxen
Propionic acid derivatives
Indomethacin, tolemtin, sulindac, ketorolac
Acetic acid derivatives
Piroxicam, tenoxicam
Oxicam
Celecoxib, parecoxib etoricoxib
Selective Cox-2 Inhibitors
better tolerated than ASA
Ibuprofen
Analgesic, antipyretic, anti-inflammatory efficacy less than ASA
Ibuprofen
T/F: Ibuprofen is well-absorbed, >90% bound to plasma proteins and cross BBB
T
Ibuprofen is metabolized in the ______, excreted in ________
liver; bile and kidneys
Ibuprofen dosage forms
Oral, parenteral, topical use (gel, cream)
available as patch, capsule, tablet
Ketoprofen
used in the eye for anti-inflammatory property
Flurbiprofen
longer acting
Naproxen
Propionic Acid ADR
nausea, vomiting, GI discomfort, fluid retention
