3. 1. Introduction
Pain: An unpleasant sensory & emotional experience associated with actual or potential
tissue damage
Analgesic :A drug that selectively relieves pain by acting in the CNS or on peripheral pain
mechanisms, without significantly altering consciousness
Classes of analgesic drugs
⢠Nonsteroidal anti-inflammatory drugs (NSAIDS)
⢠Enzyme derived analgesics derived from natural products (natureceuticals)
⢠Opioid analgesics
5. Eicosanoids (prostaglandins, thromboxanes,leukotrienes, lipoxins)
Eicosanoids are involved in most types of Inflammation
PGI2 (prostacyclin) is located predominantly in vascular endothelium.
Main effects:â˘vasodilatation â˘inhibition of platelet aggregation
TxA2 is found in the platelets.
Main effects:â˘platelet aggregation â˘vasoconstriction
PGE2 causes:⢠inhibition of gastric acid secretion â˘contraction of pregnant uterus â˘contraction of GI
smooth muscles
PGF2Îą â main effects:â˘contraction of bronchi â˘contraction of miometrium
6. Mechanism of Action of NSAIDs
Inhibition of the enzyme cyclooxygenase (COX).
Cyclooxygenase is required to convert arachidonic acid into thromboxanes,
prostaglandins, and prostacyclins.
COX-1 gets constitutively expressed in the body, and it plays a role in maintaining
gastrointestinal mucosa lining, kidney function, and platelet aggregation.
COX-2 is not constitutively expressed in the body; and instead, it inducibly expresses
during an inflammatory response.
COX-3 (in brain)

11. PHARMACOLOGICAL ACTIONS OF SALICYLATES
⢠Analgesic: 600mg equivalent to 60mg codeine.
⢠Antipyretic: promotes heat loss, resets hypothalamic thermostat.
⢠Anti-inflammatory: 3-6gm/day; quenching of free radicals.
⢠Respiration is stimulated; dose dependant.
⢠Metabolic: inflammatory doses; may decrease blood sugar in diabetics. Increased utilization of
Glucose
⢠CVS: no direct effect in therapeutic doses. Larger doses increase cardiac output to meet increased
peripheral O2 demand caused by direct vasodilation
⢠GIT: irritate gastric mucosa. causes epigastric distress, nausea & vomiting,Promotes the local back
diffusion of the acid acute ulcers, erosive gastritis, microscopic haemorrhages
⢠Blood: irreversibly inhibits thromboxane synthesis. Interferes with Platelet aggregation (BT)
12. Side effects

retention.

Celecoxib, Etoricoxib and
Parecoxib
Coxibs are selective COX-2 inhibitors. They exert antiinflammatory, analgesic, and antipyretic
action with low ulcerogenic potential. Coxibs can cause infertility. They have
prothrombotic cardiovascular risk. It does not affect platelet aggregation at usual
doses.
Etoricoxib
a second-generation COX-2-selective inhibitor with the highest selectivity ratio of any coxibs.
It is extensively metabolized by hepatic CYP450 enzymes followed by renal excretion and has an
elimination t1/2 of 22 h.
90 mg daily of etoricoxib has superior efficacy compared with 500 mg of naproxen twice daily in the
treatment of rheumatoid arthritis over 12 weeks.
has a GI safety profile similar to other coxibs.

48. Analgesic clinical efficacy and safety in dental pain
management
Common reported adverse events of NSAIDs from COX-1 inhibitors, are dyspepsia, gastric ulceration-bleeding,
diarrhea
cardiovascular disease (congestive heart failure, atherothrombosis, myocardial infarction, ischemic stroke), reduced
renal perfusion, or nephrotic syndrome accompanied with edema, acute kidney failure in rare cases from COX-2
inhibitors.
Ibuprofen use in normal doses is one of the drugs with least risk or alternative option as selective COX-2 inhibitors.
Acetaminophen adverse effects resulting from their higher dosage, chronic use, or in patient with liver disease
Ibuprofen and naproxen are considered the safest NSAIDs. Overall risk from analgesic used in dentistry is low
49. it is recommended to suppress NSAID medication from 1â2 to 4â5 days, which also depends on the drug type
and dose regimen. NSAID usage for more than 10 days should be consulted with the practitioner.
Even though they are considered relatively safe within the recommended dosage for use of up to 10 days,
cautions should be exercised in NSAIDs-exacerbated respiratory disease, asthma, patients with prior
myocardial infarction who are receiving antithrombotic therapy and those with a history of renal disease
Due to safety concerns COX-2 selective inhibitors have been introduced as a safe alternative in dentistry
practice with superior analgesic and inflammatory conditions in periodontal diseases and after oral surgery
procedures. Etoricoxib and celecoxib groups were shown to be comparable to ibuprofen on its efficacy in the
dental pulpal pain or postoperative pain relief, third molar surgery but superior toacetaminophene
50. Naproxen is indicated in toothache and its pain relief efficacy is comparable with ibuprofen. It is comparable
with etodolac, but less effective in swelling when compared with diclofenac when they were used in oral
surgical procedures, including postoperative third molar surgery or orthodontic pain
Diclofenac is used in moderate to severe pain following third molar extraction and it could be used in an
intravenous form in risk population groups such as the elderly and renal insufficiency, postoperative
anticoagulation which uses ketorolac as the only choice for the moderate to severe acute pain. Very similar
effects were shown when transdermal diclofenac patches were used compared to oral administration .
