Definitions

  • the invention relates to migraine headaches, sometimes simply called migraine. More particularly, the invention relates to preventing, arresting, or reducing the frequency or severity of migraine.
  • Migraine is a neurological disease with a strong genetic component. It is characterized by episodes of disabling headache, often called migraine attacks. They are clinically quite different from regular headaches which are non-migrainous. There are about 100 million people with headaches in the U.S. and about 37 million of these people have migraines. The World Health Organization estimates that approximately 18 percent of Women and 7 percent of men in the U.S. suffer from migraines. People who suffer from migraine are known as “migraineurs”. Migraine ranks in the top 20 of the World's most disabling medical illnesses. (See Global Burden of Disease Study, updated 2004, World Health Organization)
  • Migraines are called primary headaches because the pain isn't caused by another disorder or disease such as a brain tumor or head injury. Some cause pain on just the right side or left side of the head (hemicrania), others result in generalized head pain. Migraine sufferers may have moderate or severe pain and usually can't participate in normal activities during the duration of the attack, because of the pain. Often when a migraine strikes, people can't think beyond trying to find a quiet, dark room. More than 90% of sufferers are unable to function normally during their migraine attacks. Because of migraine-induced disability, American employers lose more than $13 billion each year as a result of 113 million lost Work days.
  • migraine attacks lasting for at least four hours and the maigraine may last for days.
  • the range of time someone is affected by an attack is actually longer than the full-blown attack itself, as there is a pre-monitory, or build-up phase, and a post-dromal phase that can last one to two days.
  • An estimated 14 million individuals in the U.S. are classified as “chronic migraneurs”, meaning that they suffer a migraine episode a minimum of 15 days each month. For all intents and purposes, this means that with migraine symptoms usually lasting multiple days, these sufferers may experience the impact of migraine on their lives virtually every day.
  • Medication-overuse headaches occur when medications not only stop relieving pain but themselves also cause headaches. Patients then use more pain medication, which may lengthen the duration of pain of the migraine sufferer.
  • these treatments pose additional, specific risks such as drug sensitivities, cognitive symptoms and negative physiological effects, some of which are further elucidated below.
  • N SAIDs non-steroidal anti-inflammatory drugs
  • ibuprofen and naproxofen are commonly used.
  • regular use of these medications can result in abdominal pain and intestinal ulcers-often associated with hemorrhage, and they are generally not effective against more severe migraine.
  • Front-line treatments for more severe migraine include the triptans, such as sumatriptan (Imitrex), rizatriptan (Maxalt), almotriptan (Axert), naratriptan (Amerge), zolmitriptan (Zomig), frovatriptan (Frova) and eletriptan (Relpax).
  • triptans such as sumatriptan (Imitrex), rizatriptan (Maxalt), almotriptan (Axert), naratriptan (Amerge), zolmitriptan (Zomig), frovatriptan (Frova) and eletriptan (Relpax).
  • these medications can cause a condition called “serotonin syndrome” when used together with selective serotonin reuptake inhibitors (SSRIs), including Prozac, Celexa, Luvox, Zoloft, Paxil and Lexapro; or serotonin and norepinephrine inhibitors (SNRIS), including Effexor, Pristiq and Cymbalta, all of which are commonly prescribed for depression and/or anxiety.
  • SSRIs selective serotonin reuptake inhibitors
  • SNRIS serotonin and norepinephrine inhibitors
  • Serotonin syndrome is a rare, potentially life-threatening condition that occurs when an excess of serotonin-a neurotransmitter of major importance in the central nervous system (CNS) accumulates in the brain.
  • ergotamines less effective than triptans are ergotamines, such as ergotamine and dihydroergotamine. Ergotamines appear to be most useful for people who have migraines that last a long period of time, but don't have frequent migraine attacks. Side effects of ergotamines include dizziness, nausea and vomiting, cold, clammy hands and feet, muscle pain, numbness, and feelings of discomfort or anxiety. Ergotamines also can have serious interactions with a large number of drugs.
  • Medications containing narcotics, particularly codeine, are sometimes used to treat migraine headache pain for people who can't take triptans or ergotamines. Narcotics are seriously habit-forming and are usually used only as a last resort.
  • Glucocorticoids such as prednisone and dexamethasone may be used in conjunction with other medications to improve pain relief Because of the risk of adverse side effects, glucocorticoids should not be used frequently or for prolonged periods, which presents problems for chronic migraneurs.
  • beta blockers One front line treatment for reducing frequency of migraine onsets is beta blockers, which are normally and usually prescribed for high blood pressure and heart problems.
  • beta blockers produce their own, often severe side effects, including fatigue, nausea, reduced ability to exercise, insomnia, sleep problems, nightmares and vivid dreams, memory problems, depression, weight gain, and exacerbation of asthma.
  • Calcium channel blockers which are also normally prescribed for high blood pressure and heart problems, are sometimes prescribed to reduce frequency of migraine onset.
  • these drugs carry their own side effect profile, including dizziness, drowsiness, constipation, nausea, headache, rash, pitting edema of the feet, ankles and lower legs (owing to water retention), low blood pressure, tachycardia (rapid heartbeat), and flushing (reddening) of the face, neck and/or upper chest.
  • Tricyclic antidepressants are sometimes used to reduce frequency of migraine onset.
  • these drugs have a wide range of undesirable side effects, including disturbances in heart rhythm, increased sensitivity to sunlight, drowsiness, dry mouth, painful urination, sexual dysfunction, weight gain, dizziness, lightheadedness, and headaches.
  • antidepressants come with the U.S. Food and Drug Administration's strongest “black box” warning that the use of antidepressants has been associated with an increased risk of suicidal thoughts and behaviors in children, adolescents and young adults. Tricyclic antidepressants can be fatal in overdose.
  • Anticonvulsants are sometimes prescribed to reduce frequency of migraine onset. Only Depakote (gen. valproic acid) and Topamax (gen. topiramate) have been approved for this purpose. However, some anticonvulsant medications may reduce the effectiveness of oral contraceptives, since their induction of the hepatic cytochrome P450 (CYP45 0) isoenzyme causes decreased sex hormone levels in women taking oral contraceptives, thus raising the potential for decreased effectiveness of oral contraceptives and increased risk of unplanned pregnancy. In addition, more than half of people who take anticonvulsant drugs report experiencing at least one side effect, the most common of which are dizziness, nausea and sleepiness. Some people who take newer drugs in this class also experience swelling in the feet and hands, weight gain, blurry vision, trouble concentrating, and lapses in memory.
  • Botox® botulinum toxin
  • Botox's side effects include headache, facial loss of movement, eyelid drooping, lung inflammation, neck pain, muscle stiffness and weakness, muscle pain and spasms, pain at injection site, and high blood pressure.
  • the paralyzing effect of Botox can spread to other areas of the body and can cause general weakness, double vision, difficulty swallowing, voice and speech disorders, loss of bladder control and difficulty breathing.
  • ketogenic diet for this purpose (see Maggioni. F. et al. Cephalalgia 31. 1150-1).
  • ketogenic dieting as potentially causing severe headaches, and low glucose levels, among a number of other physiological effects of ketogenic dieting, which might complicate its use.
  • adherence to a ketogenic diet can be difficult and compliance problems frequently arise.
  • the invention provides effective, safer treatments to prevent or reduce frequency of migraine onset and reduce migraine symptoms.
  • the present inventors have surprisingly discovered that providing ketogenic medium chain triglycerides (KMCT) to patients suffering from frequent migraine attacks can reduce frequency of migraine onset and reduce migraine symptoms, without the side effects of medications currently used for this purpose.
  • KMCT are metabolized in the liver to provide a rich source of ketone bodies, which can be metabolized as a carbon and energy source for the body, especially the brain.
  • ketone bodies can be metabolized as a carbon and energy source for the body, especially the brain.
  • providing exogenous KMCT does not result in reduced glucose concentrations or other physiological effects associated with ketogenic dieting, and does not suffer from similar patient compliance issues.
  • Ingestion of KMCT has no reported serious side effects and only minor and transitory reported effects of gastro-intestinal distress or sensitivity in some users, which has been shown to usually diminish with continued use.

Description

    RELATED APPLICATIONS
  • This is a divisional of U.S. application Ser. No. 15/743,448 entitled “Prophylaxis and Mitigation of Migraine Headache Using Medium Chain Triglycerides Ketone Esters, and Other Ketogenic” filed on Jan. 10, 2018, which has now been granted a Notice of Allowance.
  • FIELD OF THE INVENTION
  • The invention relates to migraine headaches, sometimes simply called migraine. More particularly, the invention relates to preventing, arresting, or reducing the frequency or severity of migraine.
  • BACKGROUND OF THE INVENTION
  • Migraine is a neurological disease with a strong genetic component. It is characterized by episodes of disabling headache, often called migraine attacks. They are clinically quite different from regular headaches which are non-migrainous. There are about 100 million people with headaches in the U.S. and about 37 million of these people have migraines. The World Health Organization estimates that approximately 18 percent of Women and 7 percent of men in the U.S. suffer from migraines. People who suffer from migraine are known as “migraineurs”. Migraine ranks in the top 20 of the World's most disabling medical illnesses. (See Global Burden of Disease Study, updated 2004, World Health Organization)
  • Migraines are called primary headaches because the pain isn't caused by another disorder or disease such as a brain tumor or head injury. Some cause pain on just the right side or left side of the head (hemicrania), others result in generalized head pain. Migraine sufferers may have moderate or severe pain and usually can't participate in normal activities during the duration of the attack, because of the pain. Often when a migraine strikes, people can't think beyond trying to find a quiet, dark room. More than 90% of sufferers are unable to function normally during their migraine attacks. Because of migraine-induced disability, American employers lose more than $13 billion each year as a result of 113 million lost Work days.
  • Many people experience migraine attacks lasting for at least four hours and the maigraine may last for days. The range of time someone is affected by an attack is actually longer than the full-blown attack itself, as there is a pre-monitory, or build-up phase, and a post-dromal phase that can last one to two days. An estimated 14 million individuals in the U.S. are classified as “chronic migraneurs”, meaning that they suffer a migraine episode a minimum of 15 days each month. For all intents and purposes, this means that with migraine symptoms usually lasting multiple days, these sufferers may experience the impact of migraine on their lives virtually every day.
  • Recent research has highlighted the potential importance of neurogenic inflammation in migraine pathophysiology and pharmacology. Extravasation (inflammatory leakage of white blood cells from the capillaries), vasodilatation (widening of blood vessels resulting in lowered blood pressure), mast cell activation, and the release of pro-inflammatory mediators may activate trigeminal afferents (the nerve fibers of the fifth cranial nerve governing sensation in the face and certain facial motor activity), thus leading to sensitization in the migraineur. There are indications that blockading vasodilatation in inflammation may be effective in the treatment of migraine. It has been shown that the ketone body [3-hydroxybutyrate has beneficial effects on inflammation, with significant potential for addressing aspects of a variety of metabolic related diseases.
  • Current Treatments of Migraine:
  • A number of different medications have been used to treat migraine, with varying levels of effectiveness. All of these treatments, however, with increased frequency of use can lead to a condition called medication overuse headache (MOH). Medication-overuse headaches occur when medications not only stop relieving pain but themselves also cause headaches. Patients then use more pain medication, which may lengthen the duration of pain of the migraine sufferer. In addition, these treatments pose additional, specific risks such as drug sensitivities, cognitive symptoms and negative physiological effects, some of which are further elucidated below.
  • For pain associated with mild or moderate migraine, aspirin or non-steroidal anti-inflammatory drugs (N SAIDs, such as ibuprofen and naproxofen) are commonly used. Unfortunately, regular use of these medications can result in abdominal pain and intestinal ulcers-often associated with hemorrhage, and they are generally not effective against more severe migraine.
  • Front-line treatments for more severe migraine include the triptans, such as sumatriptan (Imitrex), rizatriptan (Maxalt), almotriptan (Axert), naratriptan (Amerge), zolmitriptan (Zomig), frovatriptan (Frova) and eletriptan (Relpax). In addition to MOH, these medications can cause a condition called “serotonin syndrome” when used together with selective serotonin reuptake inhibitors (SSRIs), including Prozac, Celexa, Luvox, Zoloft, Paxil and Lexapro; or serotonin and norepinephrine inhibitors (SNRIS), including Effexor, Pristiq and Cymbalta, all of which are commonly prescribed for depression and/or anxiety. These are mental health conditions for which migraneurs already may be receiving treatment with some frequency. The front-line medications, discussed above, are often serotonin agonists whose nature it is to raise serotonin levels. When taken in combination, they can cause serotonin levels in the CNS (central nervous system) to rise to especially high levels. “Serotonin syndrome” is a rare, potentially life-threatening condition that occurs when an excess of serotonin-a neurotransmitter of major importance in the central nervous system (CNS) accumulates in the brain.
  • Less effective than triptans are ergotamines, such as ergotamine and dihydroergotamine. Ergotamines appear to be most useful for people who have migraines that last a long period of time, but don't have frequent migraine attacks. Side effects of ergotamines include dizziness, nausea and vomiting, cold, clammy hands and feet, muscle pain, numbness, and feelings of discomfort or anxiety. Ergotamines also can have serious interactions with a large number of drugs.
  • Medications containing narcotics, particularly codeine, are sometimes used to treat migraine headache pain for people who can't take triptans or ergotamines. Narcotics are seriously habit-forming and are usually used only as a last resort.
  • Glucocorticoids, such as prednisone and dexamethasone may be used in conjunction with other medications to improve pain relief Because of the risk of adverse side effects, glucocorticoids should not be used frequently or for prolonged periods, which presents problems for chronic migraneurs.
  • Due to the severity and frequency of the side effects caused by many of these medications that treat symptoms of migraine, another strategy is to utilize medications that reduce the frequency of migraine attacks.
  • One front line treatment for reducing frequency of migraine onsets is beta blockers, which are normally and usually prescribed for high blood pressure and heart problems. Unfortunately, beta blockers produce their own, often severe side effects, including fatigue, nausea, reduced ability to exercise, insomnia, sleep problems, nightmares and vivid dreams, memory problems, depression, weight gain, and exacerbation of asthma.
  • Calcium channel blockers, which are also normally prescribed for high blood pressure and heart problems, are sometimes prescribed to reduce frequency of migraine onset. However, these drugs carry their own side effect profile, including dizziness, drowsiness, constipation, nausea, headache, rash, pitting edema of the feet, ankles and lower legs (owing to water retention), low blood pressure, tachycardia (rapid heartbeat), and flushing (reddening) of the face, neck and/or upper chest.
  • Tricyclic antidepressants are sometimes used to reduce frequency of migraine onset. Unfortunately, these drugs have a wide range of undesirable side effects, including disturbances in heart rhythm, increased sensitivity to sunlight, drowsiness, dry mouth, painful urination, sexual dysfunction, weight gain, dizziness, lightheadedness, and headaches. In addition, antidepressants come with the U.S. Food and Drug Administration's strongest “black box” warning that the use of antidepressants has been associated with an increased risk of suicidal thoughts and behaviors in children, adolescents and young adults. Tricyclic antidepressants can be fatal in overdose.
  • Anticonvulsants are sometimes prescribed to reduce frequency of migraine onset. Only Depakote (gen. valproic acid) and Topamax (gen. topiramate) have been approved for this purpose. However, some anticonvulsant medications may reduce the effectiveness of oral contraceptives, since their induction of the hepatic cytochrome P450 (CYP45 0) isoenzyme causes decreased sex hormone levels in women taking oral contraceptives, thus raising the potential for decreased effectiveness of oral contraceptives and increased risk of unplanned pregnancy. In addition, more than half of people who take anticonvulsant drugs report experiencing at least one side effect, the most common of which are dizziness, nausea and sleepiness. Some people who take newer drugs in this class also experience swelling in the feet and hands, weight gain, blurry vision, trouble concentrating, and lapses in memory.
  • More recently, injections of botulinum toxin (Botox®) have been used to reduce frequency of migraine onset. However, Botox's side effects include headache, facial loss of movement, eyelid drooping, lung inflammation, neck pain, muscle stiffness and weakness, muscle pain and spasms, pain at injection site, and high blood pressure. In addition, the paralyzing effect of Botox can spread to other areas of the body and can cause general weakness, double vision, difficulty swallowing, voice and speech disorders, loss of bladder control and difficulty breathing. Given the frequency and severity of side effects of both medications to treat symptoms of migraine and to reduce frequency of migraine onset, there clearly is a need for safer treatments to prevent or reduce frequency of migraine onset and reduce migraine symptoms. Although not yet a medically accepted treatment for migraine, some references have suggested the use of a ketogenic diet for this purpose (see Maggioni. F. et al. Cephalalgia 31. 1150-1). However, some authors have described ketogenic dieting as potentially causing severe headaches, and low glucose levels, among a number of other physiological effects of ketogenic dieting, which might complicate its use. In addition, adherence to a ketogenic diet can be difficult and compliance problems frequently arise.
  • SUMMARY OF THE INVENTION
  • The invention provides effective, safer treatments to prevent or reduce frequency of migraine onset and reduce migraine symptoms. The present inventors have surprisingly discovered that providing ketogenic medium chain triglycerides (KMCT) to patients suffering from frequent migraine attacks can reduce frequency of migraine onset and reduce migraine symptoms, without the side effects of medications currently used for this purpose. KMCT are metabolized in the liver to provide a rich source of ketone bodies, which can be metabolized as a carbon and energy source for the body, especially the brain. Unlike ketogenic dieting, providing exogenous KMCT does not result in reduced glucose concentrations or other physiological effects associated with ketogenic dieting, and does not suffer from similar patient compliance issues. Ingestion of KMCT has no reported serious side effects and only minor and transitory reported effects of gastro-intestinal distress or sensitivity in some users, which has been shown to usually diminish with continued use.
