- tx: Postpartum bleeding and labor induction when oxytocin resistant - Important Side Effects: ergotism (vasoconstriction) leading to gangrene and bowel infarction - Important Interactions: Contraindicated in CV disease and pyschosis Amine Ergots: small ergots and better absorbed; more selective parial for serotonin prob less impt drug other CI: obstructive vascular or collagen disease; HTN, preg, psychosis |
|
ergots side effects
|
nl dose-diarrhea and N/V
high doses- CNS stim and hallucination think LSD |
|
contraindications of amine ergots
|
obstructive vascular or collagen disease; HTN, preg, psychosis
|
|
Amino Acid Ergots
|
alkaloids most effective given early in migraine attack; SE: N/V, diarrhea, mm cramps, cold skin, paresthesias, and vertigo; CI in CV disease; may casued cerebral VC, ischemia, and rebound VD and headache for several days; intx w/ BB for peripheral ischemia; large, bad bioavailability, low potency; less selective; more widespread effects; can become additive
can add caffiene |
|
Dihydroergotamine
|
intranasal and injectable
- Ergot Alkaloid (5HT agonist) Non-selective; - Tx: ACUTE Moderate to severe migraine; DHE often w/ antiemetic drugs such as metoclopramide to prevent drug-induced N/V; in VD; pot fo rdependance, given for withdrawel w/ dysphria - Important Side Effects: diarrhea, mm cramps, cold skin; - Important Interactions: Contraindicated in CV disease and pyschosis amino acid ergot |
|
Ergotamine
|
(ergomar, ergostat, medihaler-ergotamine) parenteral, oral, and rectal (may stim nausea center); may have caffeine for VC too
- Class: ergot alkaloid (5HT ) agonist Nonselective - tx: ACUTE Moderate to Severe Migraine; pot for dependance in VD phase; may b egiven to combat withdrawel in dysphoria - Important Side Effects: ergotism (vasoconstriction) leading to gangrene and bowel infarction; stim a1-adrenoceptor to stim vascular smNOT use in CAD or peripheral vascular disease - Important Interactions: Contraindicated in CV disease and pyschosis AA ergot |
|
Ergotamine Tartrate
|
AA ergot
- Class: Ergot agonist at 5HT Rc (5HT-1D/B) - tx: acute treatment of moderate to severe migraine - Important Side Effects: ergotism (vasoconstriction) leading to gangrene and bowel infarction - Important Interactions: Contraindicated in CV disease and pyschosis ??? impt??? |
|
Bromocriptine
|
(first ergot that was truly DA selective)
- Used in Hyperprolactinemia (DA inhibits prolactin secretion), Parkinsons, and Acromegaly - This is a DA D2 Rc Agonist, so it inhibits prolactin secretion w/ little effect on other pituitary hormones, replaces lost DA in Parkinson’s patient, and lowers blood levels of growth hormone in patients w/ acromegaly. AA ergot; SE: N/V, diarrhea, mm crmaps, cold skin ect |
|
lithium
|
used to prevent headaches at the 1st phase that reduces VC; used to treat cluster headaches
|
|
cluster headaches
|
primary headache;
severe, unilateral retro-orbital; cluster over time, min sensory input impacts; searing burning pain behind one eye w/ fast onset; 15 min-3 hrs at same time each day; agitated w/ pressure to orbit or hurt them selves to distract form pain; lithium, methy sergide and verapamil prevent these and DHE, ergotamin, glucocorticoids, lidocains, O2 and sumatriptan abort them |
|
2 phases of migraines
|
2 phases:
Cerrebral VC (and ischemia; release serotonin (anti plt drugs work)) followed by cerebral VD (long cerebral VD and pain; trigeminal neruovascular system release vasoactive peptides like substance P and calitonic gene) (primary headache) |
|
migraine is
|
Moderate or severe, often unilateral, usually pulsatile; occur with or without aura; often w/ powerful sensory input impacts
|
|
drugs to prevent migraine as prophylaxis
|
β-Adrenoceptor antagonists, anticonvulsants, antidepressants, calcium channel blockers, NSAIDs, and serotonin 5-HT2 receptor antagonists
|
|
drugs to abort migraines
|
DHE, ergotamine, isometheptene, NSAIDs, tramadol, and triptans
|
|
Tension headaches
|
Mild or moderate, bilateral, nonpulsatile; exert band-like pressure; correct cervical or dental alignment or visual error
|
|
treat tension headaches to prophylax
|
amitriptyline
|
|
treat tension headaches to abort w/
|
mm relaxants and NSAIDs
|
|
secondary headaches
|
vary depend on underlying cause; disease; no drugs to treat
|
|
serotonin Rc agonists treat
|
sumatriptan and ergotamine; treat migraine to abort in 2nd phase
|
|
propanolol tx
|
prevnet migraines as BB
|
|
timolol
|
prevents migrains BB
|
|
NSAIDs
|
prevent and abort migraines; naproxen and fenoprofen
|
|
