Definitions

• the present formulation relates to the field of pharmaceutical treatments for pain and in particular to severe headache such is produced by a migraine episode.
• migraine is used herein to mean both common migraine headache and classic migraine headache, and also any human severe headache condition although some such conditions may be referred to by other terminology in the field of medicine or by the general public.
• Migraine is a painful, sometimes debilitating disorder, which is frequently associated with various neurological symptoms. Its prevalence in the population is higher than that of any other neurological disorder, thus the burden of this disease on society is considerable. Although the introduction of triptans nearly two decades ago revolutionized the treatment of the disease there is still a strong need for a more effective pharmacology.
• migraine therapy primarily aimed at treating the pathological alterations of meningeal blood vessels that are thought to directly initiate migraine.
• abnormal neural function may be a greater cause in the development of the disease and also in triggering an episode.
• Migraine is now believed to be associated with an increased neuronal excitability and episodes of cortical spreading depression.
• a migraine may include intense throbbing pain, nausea, and sensitivity to light (aura) and sound. The condition is relatively common in adults aged 25 through 55 and is more prevalent in women. Triptans have been used in medications for the treatment of migraine. Included are: Sumatriptan®, Rizatrptan®, Naratriptan®, Zolmitriptan®, Eletriptan®, Almotriptan®, Frovatriptan®, and Avitriptan®. While effective in treating the occurrence of migraine, they have not proven effective for preventive treatment and do not provide long term relief. They act by temporarily constricting the brain's blood vessels relieving swelling. The etiology of migraine is not yet fully understood although a body of scientific research shows that certain biochemical mechanisms are repeatedly found in the pathophysiology of migraine including migraine with and also without aura.
• a medication is needed that can be taken orally, and which allows accelerated delivery of medication to the central nervous system so as to reduce or eliminate the pain associated with migraine.
• An effective remedy, described herein, has been found to be effective in treating migraine headache from onset to completion.
• Figures 1 and 2 are example line graphs of subjective levels of migraine pain intensity plotted against time (minutes).
• Figure 3 is a typical filled-out data sheet by a subject of the clinical study upon which this application is based and is signed by the Director of the study Ms. Christine Mack, PhD.
• the presently described remedy includes a medication formulation and a proposed delivery method for treating migraine.
• the formulation may include active ingredients: nicotine, tryptophan, phenylalanine, tyrosine, and caffeine, incorporated into a two fluid ounce aqueous solution to be consumed as a beverage. Other ingredients may be added as well such as preservatives and flavorings.
• the liquid portion of the solution is not active and may be water or almost any other fluid.
• Fig. 1 shows migraine pain intensity plotted against time, with each data point representing the mean of five subjects, and also shows plus/minus standard error of the mean. No adverse side-effects were reported by the subjects during the study.
• Fig. 2 again shows migraine pain intensity plotted against time for a single subject. The graph shows the average pain intensity of 11 migraine episodes in 15 minute intervals experienced over a two month period.
• the active ingredients in the beverage may be formulated in the following weight percentages: nicotine 0.11% tryptophan 18.1%
• Nicotine acts as an anti-inflammatory agent in multiple cell types and may be beneficial in central nervous system disorders associated with inflammatory responses such as Alzheimer's and Parkinson's disease. As migraine is also believed to be the result of inflammation of blood vessels in the brain, it is hypothesized that nicotine may alleviate migraine pain through an anti-inflammatory mechanism.
• Tryptophan is known to treat stress which is an environmental trigger for migraine and, as mentioned above, a low serotonin level may be a factor in developing migraine.
• a low serotonin level may be a factor in developing migraine.
• the combination of these two chemicals act to provide an anti-inflammatory effect and reduce stress, both mechanisms which may mitigate migraine pain.
• the formulation may also contain non-essential amino acids such as serine, aspartic acid, and glutamic acid which act as excitatory neurotransmitters to the central nervous system including, the brain and the spinal cord.
• non-essential amino acids such as serine, aspartic acid, and glutamic acid which act as excitatory neurotransmitters to the central nervous system including, the brain and the spinal cord.
• the formulation may theoretically be inhaled, ingested, injected, received trans- dermally or by any other transport means. Ingestion by drinking the beverage has been shown to be effective.
• the medication formulation for treating migraine comprises an aqueous solution, the beverage, containing active ingredients including an effective amount of: nicotine, tryptophan, phenylalanine, tyrosine and caffeine, wherein the nicotine comprises not less than 0.222 mg.
• active ingredients including an effective amount of: nicotine, tryptophan, phenylalanine, tyrosine and caffeine, wherein the nicotine comprises not less than 0.222 mg.
• the formulation of an effective amount of nicotine and tryptophan alone provides many of the benefits of the full formulation. Adding an effective amount of phenylalanine improves results for some subjects. Further adding an effective amount of tyrosine improves results for further subjects, and further adding an effective amount of caffeine improves results even further for some subjects.
• the solution may have 0.222 mg nicotine, 40 mg tryptophan, 20 mg phenylalanine, 60 mg tyrosine, and 85 mg caffeine in two liquid ounces of water or equivalent liquid. Additionally, it has been found that a non-essential amino acid for example: serine, aspartic acid, and glutamic acid may have beneficial results.
