Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] FIG. 1 is a diagram showing sleep apnea patient's oxygen saturation levels (SpO2). Oxygen saturation levels (SpO2) in the blood during sleep were monitored using Wellure's O2Ring.

[0018] FIG. 2 is a diagram showing sleep apnea patient's oxygen saturation levels (SpO2) when a patient took 25 mg of ephedrine one hour before going to bed along with a sleeping pill Avinol PM just before going to bed. Oxygen saturation levels (SpO2) in the blood during sleep were monitored using Wellure's O2Ring.

[0019] FIG. 3 is a diagram showing sleep apnea patient's oxygen saturation levels (SpO2) when a patient took 25 mg of ephedrine one hour before going to bed along with one tablet of the sleeping pill Avinol PM just before going to bed. The patient took another 25 mg of ephedrine three hours after going to bed. Oxygen saturation levels (SpO2) in the blood during sleep were monitored using Wellure's O2Ring.

DETAILED DESCRIPTION OF EMBODIMENTS

[0020] Ephedra (ma huang) has been used as a respiratory bronchodilator in Chinese medicine since ancient times (>2,000 years). Ephedrine is the main active ingredient of ephedra. In 1885, Japanese organic chemist Nagai Nagayoshi chemically synthesized ephedrine, and its industrial manufacturing in China began in the 1920s, when Merck began marketing and selling the drug as ephetonin.

[0021] Ephedrine belongs to a class of compounds called a catecholamine (neurotransmitter) and is chemically and structurally related to norepinephrine, a sympathetic nervous system (SNS) stimulant similar to amphetamines. Ephedrine interacts with the adrenergic receptors (alpha and beta receptors), increases the activity of norepinephrine, and helps release noradrenaline and dopamine in the substantia nigra. Since the adrenergic receptors are prevalent and found not only in the SNS (brain) but also in many cells throughout the body, ephedra or ephedrine affects many cells throughout the body.

[0022] Ephedrine is a potentially dangerous natural compound. As of 2004 the US Food and Drug Administration (FDA) had received over 18,000 reports of adverse effects in people using it. Cardiovascular problems, hypertension, flushing, sweating, nausea, difficulty urinating, restlessness, confusion, insomnia, hallucination, agitation, and many other problems are reported. Because of this, in 2004, the FDA created a ban on ephedrine alkaloids marketed for reasons other than asthma, colds, allergies, other diseases, or traditional Asian use. Subsequently, ephedrine was banned by the NCAA, MLB, NFL, and PGA. Ephedrine is, however, still legal in many applications outside of dietary supplements. Purchasing is currently limited and monitored, with specifics varying from state to state. George W. Bush signed the Combat Methamphetamine Epidemic Act of 2005. The federal statute includes these requirements for merchants who sell ephedrine: [0023] A retrievable record of all purchases identifying the name and address of each party to be kept for two years [0024] Required verification of proof of identity of all purchasers [0025] Required protection and disclosure methods in the collection of personal information

[0026] Legality of ephedrine use (and purchase) varies from country to country. Canada, Australia, South Africa, Germany, and Japan have restrictions, but Japan has eased restrictions this year.

[0027] It has been found that a sleeping pill or a kit including the pill that contains a therapeutically effective amount of ephedrine can significantly improve apnea patient's oxygen saturation levels (SpO2), and thus is useful in effectively treating the sleep apnea.

[0028] As shown in FIG. 1, sleep apnea patient's oxygen saturation levels (SpO2) were wildly fluctuated during sleep. A few breathing interruptions like these are enough to ruin a good night's sleep.

[0029] As shown in FIG. 2, the sleep apnea patient's oxygen saturation levels (SpO2) were improved when the patient took 25 mg of ephedrine one hour before going to bed along with a sleeping pill Avinol PM (trademark) just before going to bed. Breathing problems observed in FIG. 1 were greatly reduced in the first three hours but came back when the ephedrine was metabolized in about four hours.

[0030] As shown in FIG. 3, the sleep apnea patient's oxygen saturation levels (SpO2) were improved when the patient took 25 mg of ephedrine one hour before going to bed along with one tablet of the sleeping pill Avinol PM (trademark) just before going to bed. The patient took another 25 mg of ephedrine three hours after going to bed.

[0031] FIGS. 2 and 3 indicate that ephedrine can preferably be taken in the sustained or extended release form to keep it active throughout the night.

[0032] The ephedrine may be administered in combination with other ingredients or medications. For example, at least one ingredient selected from chamomile, hops, passionflower, lemon balm, valerian, melatonin, GABA, L-theanine, L-tryptophan, 5-HTP, ashwagandha, schizandra, reishi, maitake, Ganoderma lucidum, lion's mane, chaga, or Cordyceps, and any combination thereof may be administered in appropriate combinations with ephedrine and amounts to counter (reduce) stimulatory (agitating) effects of the ephedra or ephedrine on sleep.

[0033] The sleep apnea treatment with ephedrine may be provided in the form of a kit. The kit may include the sleeping pill that contains a therapeutically effective amount of ephedrine and appropriate instructions for a patient who needs sleep apnea treatment to take the pill in the manner disclosed in the present application.

[0034] In another aspect, a pharmaceutical composition for treating sleep apnea is provided which includes a therapeutically effective amount of ephedrine, for example, 5.0 mg to 100.0 mg, or preferably 12.5 mg to 25.0 mg of the ephedrine, and optionally any pharmaceutically acceptable carrier, and optimally any other ingredients disclosed in the present application. In another aspect, use of the ephedrine for the manufacture of the pharmaceutical composition for treating sleep apnea is provided.
