Dental Pain Flashcards
(36 cards)
What are the two main types of pain?
1-Musculoskeletal (somatic, inflammation)
2-Visceral
Which 3 groups of neurotransmitters have a direct pain modulation on the brain?
1-Opioid narcotics
2-Glu, GABA
3-Antidepressants (5HT/NE)
What two Neurotransmitters have descending modulation effects in the spinothalamic tract?
- Serotonin drugs
- Neuropeptides
Which three groups of drugs have an effect on pain in the dorsal horn?
1-Local anesthetic
2-Opioids
3-NSAIDs
Which two drugs affect peripheral nerves to modulate pain?
1-Local anesthetic
2-Opioids
Which 4 drug groups modulate pain by acting on peripheral nociceptors?
1-Local anesthetic
2-NSAIDs (COX 1/2 inhib)
3-Acetaminophen
4-Capsaicin
Arachidonic acid is converted by COX1 into PGE2 and Thromboxane A2 and has side effects in what 4 areas?
1-Gastric mucosal barrier
2-Renal function
3-Platelet Aggregation
4-Vasoconstriction
Arachidonic acid is converted by COX2 into Prostaglandins and Prostacyclin and has side effects in what 3 areas?
1-Pain, inflammation, fever
2-Renal function
3-Vasodilation
*COX-1 can contribute to this as well
What two drugs are Non-selective COX-1 and COX-2 inhibitors?
1-Salicylates (aspirin)
2-Ibuprofen-like
*Others as well
Which drug is a Selective Cox 2 inhibitor?
Celebrex (Celecoxib)
Which drug is NOT and NSAID but in a non-opioid analgesic?
Acetaminophen
*does not help with inflammation
Salicylates are Cox-1 and Cox-2 inhibitors that are often combined with caffeine, acetaminophen or opioids for mild-moderate somatic pain. What are 3 dose dependent effects of these drugs?
1-Analgesia (600 mg)
2-Antiinflammation (1 gm)
3-Antipyretic (300-600 mg)
*4 hour duration
What are the 4 side effects of salicylates?
1-G.I. Irritation and erosion
2-Reyes syndrome in children (Cold/flu)
3-Anti-clotting (lasts 1-2 weeks)
4-RInging in ears (tinnitis, at higher doses)
Ibuprofen is a cox-1 and cox-2 inhibitor that is often a little better for mild-moderate pain and has what 3 effects?
1-Analgesia (400 mg)
2-Anti-inflammation (800 mg)
3-Antipyretic (400 mg)
*4 hour duration
What are 3 side effects of ibuprofen?
1-GI ulcers (less than aspirin)
2-Anti-clotting (less than aspirin)
3-Cardiovascular effects
Which Ibuprofen-like drug is more potent and has lower doses (50 mg/Capsule)?
Ketoprofen (Orudis)
Which Ibuprofen-like drug is longer-lasting and slower acting?
Naproxen (Naprosyn)
*Aleve is also one of the longer lasting ones
Which drug has the same analgesic potency as ibuprofen, lacks GI and anti-clotting action, has been linked with CV side effects and is a Cox-2 selective antagonist?
Celecoxib (Celebrex)
*Rx only
Which drug is a potent non-selective NSAID used for arthritis but is not a common analgesic due to its side effects?
Indomethacin
*good for inflammation
Which alternate drug preferentially inhibits Cox-2 over Cox-1 resulting in less GI problems?
Meloxicam
Which drug is related to salicylates and is good for bone pain?
Diflunisal (Dolobid)
*Oral surgeons use frequently
Which drug is not a Cox 1 or 2 inhibitor, is not an anti-inflammatory and has a mysterious mechanism (COX 3/Serotonin?)?
Acetaminophen
Though acetaminophen does not achieve the same analgesia or anti-inflammation that aspirin can, what are 5 advantages to it?
1-Good antipyretic 2-Stable in solution (for kids) 3-No GI problem 4-No effect on clotting 5-No Reye's syndrome
What is the main serious side effect of acetaminophen?
Liver toxin in high doses
*Do not use in those with compromised livers
