Migraine - Acute drug treatment

17 important questions on Migraine - Acute drug treatment

When are OTC drugs used for migraines? And what are they?

Try for mild-mod migraines
acetaminophen, aspirin, naproxen, Advil Migraine (only has ibuprofen).
combos: Excedrin Migraine (aspirin, acetaminophen, caffeine)

What drugs are not recommended for migraines due to decreased efficacy, abuse/dependence potential and risk of rebound headache (MOH)?

Butalbital products, opioids, tramadol and tapentadol

1st line for acute treatment of migraines

Triptans- selective 5-HT1 (serotonin) receptor agonists- they vasoconstrict cranial blood vessels, inhibit neuropeptide release and decrease pain transmission.

Triptan warnings and side effects

Increased BP, serotonin syndrome if used with another serotonergic drug
Paresthesia (tingling/numbess), "triptan sensations" (pressure or heaviness in chest or pressure in the neck region)

Sumatriptan SC dosing

Imitrex, Imitrex STATdose: 4 or 6 mg, can repeat x1 after 1 hr (max 12mg/day)
Zembrace: can repeat up to 4x/day

Preferred site is lateral thigh or upper arm  

Sumatriptan intranasal dosing

Spray: in 1 nostril, can repeat x1 after 2 hrs
Powder
: 11 mg in each nostril using nosepiece, can repeat x1 after 2 hrs (max 44 mg/day)

Which triptans are approved for >/= 12 years old?

Almotriptan tabs, zolmitriptan nasal spray, RizaFilm and Treximet

Which triptans are approved for >/= 6 years old?

Rizatriptan tabs and ODT

Which triptan has the longest half life? Considered long acting? Shorter half life?

Longest half life- frovatriptan
Long acting, slower onset
- frovatriptan, naratriptan [choose if headache recurs after dosing, lasts long time or can be anticipated]
Shorter half life, faster onset- all other triptans

Which triptans are CI with MAO inhibitors (or within 2 weeks of stopping) due to increased triptan conc when used together?

Sumatriptan, rizatriptan, zolmitriptan

What type of drug is an option for patients that do not benefit from a triptan?

Ergotamine- nonselective serotonin receptor agonist- causes vasoconstriction

Ergotamine BBW and CI

Life threatening peripheral ischemia [CI w/ potent CYP3A4 INhibitors (protease inhibitors, macrolides)]
CI- uncontrolled htn, ischemic heart disease, pregnancy, use w/in 24 hrs of serotonin agonists (triptans) or other ergotamine drugs

Whats the difference in priming triptan nasal sprays and ergotamine nasal sprays?

Triptans only have 1 dose- do not prime
Ergotamines- prime by pumping 4 times

Which CGRP is approved to prevent and treat acute migraine attacks?

Rimegepant (Nurtec ODT)

Which CGRPs are only approved to treat acute migraine attacks?

Ubrogepant (Ubrelvy) and Zavegepant (Zavzpret)

Why is Lasmiditan (Reyvow) not CI in patients with CVD?

C-V: It is a serotonin agonist selective for 5-HT1F receptor subtype, so it does not cause vasoconstriction

Why are butalbital products NOT recommended for treating acute migraines, even though they are popular?

Abuse/dependence issues (schedule 3) and lower efficacy
