Description

DETAILED DESCRIPTION OF THE INVENTION

[0031] While the present invention is susceptible of embodiment in various forms, there is shown and will hereinafter be described a presently preferred, albeit not limiting, embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention and is not intended to limit the invention to the specific embodiments illustrated.

[0032] An embodiment of the invention provides a composition for preventing or minimizing sleep related conditions, such as snoring or sleep apnea. An embodiment of the invention further provides a method of preventing or minimizing sleep related conditions, such as snoring or sleep apnea. Preferably, the embodiment of the invention is formulated as a nasal spray with an effective amount of oxymetazoline, or pharmaceutical acceptable salts thereof. The nasal spray is configured for long term use, i.e. more than 5-7 days, without suffering one or more adverse side effects typically associated with using oxymetazoline at standard adult dosages, including rebound congestion typically seen after 5-7 days usage, or side effects such as burning/stinging, bleeding, sneezing, runny nose, headaches, or nasal obstruction.

[0033] As used herein, the term “about” or “approximately” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, i.e., the limitations of the measurement system. For example, “about” or “approximately” can mean within 1 or more than 1 standard deviation, per the practice in the art. Alternatively, “about” or “approximately” can mean a range of up to 20%, preferably up to 10%, more preferably up to 5%, and more preferably still up to 1% of a given value. Where particular values are described in the application and claims, unless otherwise stated, the term “about” meaning within an acceptable error range for the particular value should be assumed.

[0034] As used herein, the term “effective amount” or “effective concentrations” includes a sufficient amount of the nasal spray composition, when referring to the nasal spray composition in general, to provide the desired local or system effect, preferably without adverse side effects (i.e. unwanted or adverse effects of active ingredients or the composition as a whole), or to at least partially attain the desired effect. When referring to the individual component(s) of the nasal spray composition, “effective amount” may be defined as a sufficient amount of the individual component(s) to provide its intended or desired effect.

[0035] As used herein, the term “active ingredient” or “physiologically active ingredient” may be defined as ingredients, agents, compounds, individually or in combination, which exert a physiological effect.

[0036] As used herein, the term “pharmaceutically acceptable salt(s)” may be defined as those salts of compounds of the invention that are safe and effective for topical use in mammals, and that possess the desired biological activity. Pharmaceutically acceptable salts include salts of acidic or basic groups present in compounds of the invention. Pharmaceutically acceptable acid addition salts include, but are not limited to, hydrochloride, hydrobromide, hydroiodide, nitrate, sulfate, bisulfate, phosphate, acid phosphate, isonicotinate, acetate, lactate, salicylate, citrate, tartrate, pantothenate, bitartrate, ascorbate, succinate, maleate, gentisinate, fumarate, gluconate, glucuronate, saccharate, formate, benzoate, glutamate, methanesulfonate, ethanesulfonate, benzensulfonate, p-toluenesulfonate and pamoate (i.e., 1,1′-methylene-bis-(2-hydroxy-3-naphthoate)) salts. Certain compounds of the invention can form pharmaceutically acceptable salts with various amino acids. Suitable base salts include, but are not limited to, aluminum, calcium, lithium, magnesium, potassium, sodium, zinc, and diethanolamine salts.

[0037] In an embodiment of the nasal spray composition, the nasal spray composition may include effective amounts of a decongestant or vasoconstrictor, such as oxymetazoline, or pharmaceutical acceptable salts thereof, such as oxymetazoline hydrochloride. In an illustrative embodiment, the effective amount of oxymetazoline or pharmaceutical acceptable salts thereof, is less than 0.050%, between less than 0.050% and 0.010%, and more preferably, 0.025% or about 0.025%. Oxymetazoline, a member of the imidazole group, binds and activates alpha-2 adrenergic receptors. Upon nasal administration, imidazole group compounds constrict the arterioles in the nose, resulting in decreasing congestion. Concentrations of oxymetazoline (0.050%) utilized in the over-the-counter sprays have been proven to return symptoms to a degree stronger than present initially upon discontinuation of the drug. This is called the rebound effect, or rebound congestion (rhinitis medicamentosa, chemical rhinitis, or nasal spray addiction). The rebound effect may occur in as early as 3 days of use, but typically occurs in 3-5 days and sometimes 5-7 days of use. Use of oxymetazoline, or pharmaceutical acceptable salts thereof, at less than 0.050%, and preferably at 0.025%, has been determined to be effective at reducing or minimizing snoring or sleep apnea while preventing the rebound effect. As such, the nasal spray according to the present invention can be used for a time period greater than 5-7 days without the risk of suffering from any rebound effect. In use, the nasal spray was used for more than 7 days, more than 30 days, and at least six (6) months without individuals suffering from the rebound effect.

[0038] In an embodiment of the nasal spray composition, the nasal spray composition may include effective amounts of one or more essential oils, such as but not limited to tea tree oil (Melaleuca Alternifolia Leaf Oil), rosemary oil, eucalyptus oil, ginger oil, lemon oil, oregano oil, lavender oil, marjoram oil. In certain embodiments, an essential oil, such as tea tree oil, can be used at effective concentrations to do one or more of, lubricate the nose and decrease side effects, destroys germs and irritants that block airways and cause breathing difficulty, be antiseptic, anti-inflammatory, antiviral, anti-bacterial, anti-fungal, fight off yeast and other microbes, immune stimulator, reduce sinus congestion and red and itchy eyes, or reduce cold and congestion symptoms. In certain embodiments, an essential oil, such as rosemary oil, can be used at effective concentrations to do one or more of, relieve respiratory disorders, expel excess phlegm and mucous, clear the sinuses and decrease nasal congestion, lubricate the nose and decrease side effects, help fight resistant strains of bacteria that cause chronic congestion (strep pneumonia, E. coli), provide anti-fungal properties that inhibit pathogens, or disrupt fungal cell membranes. In certain embodiments, an essential oil, such as eucalyptus oil, can be used at effective concentrations to clear nasal congestion and open airways. In certain embodiments, an essential oil, such as ginger oil, can be used at effective concentrations to strengthen the immune system and fight inflammation. In certain embodiments, an essential oil, such as lemon oil, can be used at effective concentrations to help relieve cough and cold symptoms. In certain embodiments, an essential oil, such as oregano oil, can be used at effective concentrations for fighting viral infections. In certain embodiments, an essential oil, such as lavender oil, can be used at effective concentrations to sooth the respiratory tract and help with sore throat, cough and cold symptoms. In certain embodiments, an essential oil, such as marjoram oil, can be used at effective concentrations to ease respiratory disorders such as sinusitis.

[0039] In an embodiment of the nasal spray composition, the nasal spray composition may include effective amounts of a saline solution, such as a salt solution made using ANCIENT SECRETS nasal cleaning salt (a non-iodized pure salt, sodium chloride).
