Use caution with Analgesics/NSAIDs
Ulcer dz
Renal Dz
Cardiac Dz
Hypersensitivity
Analgesic/NSAID DOC for migraines
Ibuprofen and naproxen
Aspirin
Combination: Acetaminophen, aspirin, caffeine
2nd Line:
Acetaminophen, isometheptene, dichloralphenazone
Acetaminophen, butabital, caffeine
Analgesic/NSAID MOA
Inhibition of prostaglandin synthesis
Ergot Alkaloids MOA
5HT1 agonists – constrict intracranial blood vessels
Inhibition of the trigeminovascular system
-Activation of 5-HT1 receptors on sensory nerve endings of
the trigeminal system results in the inhibition of pro-
inflammatory neuropeptide release
-Prevention of neurogenic inflammation
Severity of migraine to use Analgesics/NSAIDs
Mild - Moderate
Severity of migraine to use Ergot Alkaloids
Moderate - Severe
Analgesic/NSAID ADE’s
Renal, GI (bleeding, dyspepsia, nausea), CNS (dizziness)
Ergot Alkaloids used in migraines
Ergotamine Tartrate (more potent arterial constrictor) Dihydroergotamine (DHE) - (less potent)
Ergotamine Tartrate routes
Oral
SL
Rectal
Dihydroergotamine (DHE) routes
Nasal
Parenteral
Ergotamine Tartrate can be combined with:
Caffeine
- Enhances absorption
- Aides in analgesia
