Description

DETAILED DESCRIPTION OF THE INVENTION

[0014] The present invention provides for a method of treating obesity, by administering an effective amount of 18-MC to an individual and treating obesity.

[0015] The free base 18-methoxycoronaridine (18-MC) is a synthetic coronaridine congener and a specific negative allosteric modulator (antagonist) of α3β4 nicotinic cholinergic receptors; it indirectly modulates the dopaminergic mesolimbic pathway via blockade of α3β4 nicotinic receptors in the habenulo-interpeduncular pathway and the basolateral amygdala (Glick et al., 2008).

[0016] 18-MC in the present invention can also be in the form of salts thereof, tartrates thereof, solvates thereof, isomers thereof, analogs thereof, homologues thereof, or deuterated forms thereof.

[0017] 18-MC can be administered as a single dose or as repeat doses over multiple days, weeks, months, or years. 18-MC can be administered in a dose from 0.01-10 mg/kg.

[0018] 18-MC can reduce craving for food, especially foods containing sucrose, and other related carbohydrates, thus reducing weight gain in the individual and obesity.

[0019] The present invention also provides for a method of treating binge eating, by administering an effective amount of 18-MC to an individual and treating binge eating. With binge eating disorder, an individual frequently consumes large amounts of food, and they feel unable to stop eating. A binge eating episode is defined as an individual eating in a discrete period of time (e.g., within any 2-hour period) an amount of food that is definitely larger than what most people would eat in a similar period of time under similar circumstances, and a sense of lack of control overeating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating). The binge eating episodes are associated with three (or more) of eating much more rapidly than normal, eating until feeling uncomfortably full, eating large amounts of food when not feeling physically hungry, eating alone because of feeling embarrassed by how much one is eating, or feeling disgusted with oneself, depressed, or very guilty afterward. A binge eater also does not regularly use unhealthy compensatory measures (e.g., purging) to counter the binge eating. 18-MC reduces the need to consume large amounts of food.

[0020] The present invention further provides for a method of treating behavioral addictions, by administering an effective amount of 18-MC to an individual and treating the behavioral addiction. Behavioral addictions are behaviors that often occur in response to a feeling of anxiety, urge, or negative feelings, and the behaviors can create a calming feeling in the individual and stimulate reward areas in the brain in a way that is understood to be similar to substances of misuse or abuse. The behavioral addiction can be, but is not limited to, gambling, sex, food, plastic surgery, social media, internet, risks, shopping, or pornography. 18-MC can reduce and/or eliminate the need to do the relevant behaviors when suffering from a behavioral addiction in the individual.

[0021] The compounds of the present invention are administered and dosed in accordance with good medical practice, considering the clinical condition of the individual patient, the site and method of administration, scheduling of administration, patient age, sex, body weight and other factors known to medical practitioners. The pharmaceutically “effective amount” for purposes herein is thus determined by such considerations as are known in the art. The amount must be effective to achieve improvement including but not limited to improved survival rate or more rapid recovery, or improvement or elimination of symptoms and other indicators as are selected as appropriate measures by those skilled in the art.

[0022] In the method of the present invention, the compounds of the present invention can be administered in various ways. It should be noted that they can be administered as the compound and can be administered alone or as an active ingredient in combination with pharmaceutically acceptable carriers, diluents, adjuvants, and vehicles. The compounds can be administered orally, transcutaneously, subcutaneously or parenterally including sublingual, buccal, inhalation, intravenous, intramuscular, and intranasal administration. The patient being treated is a warm-blooded animal and, in particular, mammals including man. The pharmaceutically acceptable carriers, diluents, adjuvants, and vehicles as well as implant carriers generally refer to inert, non-toxic solid or liquid fillers, diluents or encapsulating material not reacting with the active ingredients of the invention.

[0023] The doses can be single doses or multiple doses or a continuous dose over a period of several hours, days, weeks, months, or years.

[0024] When administering the compound of the present invention orally, it will generally be formulated in an immediate release capsule, immediate release tablet, modified release capsule or tablet (including enteric coatings), solution, or suspension. When administering the compound of the present invention parenterally, it will generally be formulated in a sublingual or buccal orally dissolving tablet, dissolving film, intranasal powder, intranasal solution, inhaled powder, inhaled solution, transdermal patch, transdermal patch with microneedles or other permeation enhancers, or as a unit dosage injectable form (solution, suspension, emulsion). The pharmaceutical formulations suitable for injection include sterile aqueous solutions or dispersions and sterile powders for reconstitution into sterile injectable solutions or dispersions. The carrier can be a solvent or dispersing medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, liquid polyethylene glycol, and the like), suitable mixtures thereof, and vegetable oils.

[0025] Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Nonaqueous vehicles such a cottonseed oil, sesame oil, olive oil, soybean oil, corn oil, sunflower oil, or peanut oil and esters, such as isopropyl myristate, may also be used as solvent systems for compound compositions. Additionally, various additives which enhance the stability, sterility, and isotonicity of the compositions, including antimicrobial preservatives, antioxidants, chelating agents, and buffers, can be added. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. In many cases, it will be desirable to include isotonic agents, for example, sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin. According to the present invention, however, any vehicle, diluent, or additive used would have to be compatible with the compounds.

[0026] Sterile injectable solutions can be prepared by incorporating the compounds utilized in practicing the present invention in the required amount of the appropriate solvent with various of the other ingredients, as desired.

[0027] A pharmacological formulation of the present invention can be administered to the patient in an injectable formulation containing any compatible carrier, such as various vehicle, adjuvants, additives, and diluents; or the compounds utilized in the present invention can be administered parenterally to the patient in the form of slow-release subcutaneous implants or targeted delivery systems such as monoclonal antibodies, vectored delivery, iontophoretic, polymer matrices, liposomes, and microspheres. Examples of delivery systems useful in the present invention include: U.S. Pat. Nos. 5,225,182; 5,169,383; 5,167,616; 4,959,217; 4,925,678; 4,487,603; 4,486,194; 4,447,233; 4,447,224; 4,439,196; and 4,475,196. Many other such implants, delivery systems, and modules are well known to those skilled in the art.
