Episodic Migraine; How to manage?

Identify any obvious triggers

Infrequent attacks


Acute treatment only
Frequent attacks

Acute and Preventative treatments
High Percentage of Migraine Patients Report
Triggers
76% to 95% of patients report triggers*,1
The mean number of triggers per patient is 6.71
Stress has been shown to be even
more important in chronic migraine
than in episodic migraine2

Acute Rx: Key Message



Avoid opiates or combination analgesics with
barbiturates, caffeine
Restrict the use to no more than two
days/doses per week
NSAID has the lowest potential for medication
overuse
New Rx on the Horizon





CGRP antagonists or Gepants
Glutamate Receptor Antagonists
Vanilloid (TRPV1) receptor antagonists
Nitric Oxide Synthetase inhibitors
Prostanoid Receptor Antagonist
New ways of Established Rx


Inhaled version of DHE (MAP-004 - LEVADEX©)
Triptans




Melts and sprays
Needle free injection (intraject)
Transdermal patches (Zelrix)
Sumnap (sumatriptan Naproxen combination)
MIGRAINE PROPHYLAXIS
 When
should I give migraine prophylaxis?
 Prophylaxis is used to reduce the number
of attacks in circumstances when acute
therapy, used appropriately, gives
inadequate symptom control. (BASH GUIDELINES
2010)
09/04/2015
13
Consensus view on migraine prophylaxis

Should be offered to patients with 6 or more headache days
per month; 4 or more days with some impairment; or 3 or
more days with severe functional impairment

Should be considered with 4–5 days per month with
normal functioning; 3 days with some impairment and 2
days with severe impairment

Should not be given to patients with <4 days of headache
per month with normal functioning; or no more than 1 day
per month regardless of impairment

Migraine prophylaxis treatment options

Non-pharmacological1,2
Behavioural lifestyle changes
 Anxiety management, psychotherapy and
physiotherapy


Pharmacological
 Few agents specifically licensed for migraine
prophylaxis

Non-drug interventions




Acupuncture has little benefit, if any at all
Physiotherapy for the neck as an adjunctive treatment may
be useful
 Indian head massage may be useful but the evidence is
anecdotal
Relaxation therapy, stress reduction and coping strategies
are helpful
 These interventions are in need of formal evaluation
 Yoga and meditation are said to enhance stress
management and appeal to some people1
Homeopathy offers no value2

Pharmacological options for migraine
prophylaxis1,2




Amine modulation:
 Beta blockers
 5-HT blockers (pizotifen, methysergide)
Channel modulation:
 Anticonvulsants (topiramate, epilim*)
Tricyclic Antidepressants
 Amitriptyline*
ACE inhibition:
 Lisinopril*
* Currently not licensed for migraine prophylaxis in the UK

Beta blockers

First-line if not contraindicated by asthma, heart failure,
peripheral vascular disease or depression

Use of propranolol in migraine prophylaxis1:
 58 propranolol studies met the inclusion criteria, of which
26 were placebo controlled
 Overall relative risk of response to treatment was 1.94
(95% CI 1.61 to 2.35)
 17 trials showed a significant superiority over placebo, 7 a
trend for propranolol and 2 no difference

Commonly reported adverse events include cold extremities,
reduced exercise tolerance, nightmares and dizziness

18
Amitriptyline





Used widely second only to beta-blockers
3 small trials of amitriptyline (all before 1987) show 21–42%
reduction in number of attacks
May be used first-line when migraines co-exist with
troublesome tension-type headache, another chronic pain
condition, disturbed sleep or depression
Commonly reported adverse events include dry mouth,
sedation, dizziness and nausea1
Dose used ranges between 10 and 150 mg per day1
 Individual tolerance to dosages varies and titration is highly
dependent on side-effects experienced

Topiramate





Clinical trials suggest efficacy equal to sodium valproate1
Use of topiramate in migraine prophyalxis2:
 6 (of 6) topiramate studies showed overall superiority to
placebo in the combined analysis (OR 3.34; 95% CI 2.36 to
4.73) with noticeable variation in the odds ratio across the
studies2
A dose of 100 mg reports a 50% response rate3
Cognitive side effects and tingling sensation in fingers and
toes often limit its use
Around a quarter of patients report loss of weight of
around 10% and can act as a mood stabiliser

Valproate






Sodium valproate has a response rate of around 44%1
It does not reduce the efficacy of hormonal contraception
Use of valproate in migraine prophyalxis2:
 4 (of 4) valproate studies showed active treatment was superior to
placebo in reduction in migraine frequency
(OR 3.34; 95%CI 1.46 to 7.67)2
Adverse events reported include nausea, asthenia, somnolence, weight gain
and alopecia
Blood cell count, platelet count, bleeding time and coagulation tests are
recommended prior to starting treatment and in case of spontaneous
bruising or bleeding
Liver dysfunction is reported rarely

TRANSCRANIAL MAGNETIC
STIMULATION
 TMS
devices deliver a brief magnetic pulse to
the scalp and underlying cortex, altering firing
patterns
 targets cortical spreading depression (CSD)

CSD is a wave of
excitation followed
by a wave of
inhibition
