Abstract
A nicotine method and solution which utilizes an acidic solution containing nicotine. The solution is for use to treat various medical conditions, such as to reduce the need of a user of smoking tobacco to smoke tobacco, to reduce attention deficit disorder symptoms in a person who has attention deficit disorder, and/or to reduce Alzheimer's disease symptoms in a person who has Alzheimer's disease. The solution is palatable and may be introduced into the person by the person drinking it. Subsequent to drinking, the blood plasma levels are sufficient to reduce the need to smoke tobacco, to reduce attention deficit disorder symptoms, and/or to reduce Alzheimer's disease symptoms.
Claims26
A method for providing nicotine to a person by administration to the upper gastro-intestinal tract of a selected amount of nicotine, said method comprising:
- (a) providing a palatably acceptable solution containing a therapeutically effective amount of nicotine, having an acidic pH, and being adapted for introduction into the person's upper gastrointestinal tract, and including a flavoring in the nicotine solution wherein the flavoring is selected from the group consisting of sugar, coffee, beer, wine, whiskey, fruit juice, milk, soda, and combinations thereof;
- (b) administering the nicotine solution to the person's upper gastro-intestinal tract so as to introduce the nicotine to the metabolism of the person, wherein the administering is free of buccal administering and free of sublingual administering;
- and
- (c) periodically repeating (b), so as to administer a selected amount of the nicotine to the person's metabolism after the first-pass absorption to the liver so that the nicotine achieves a selected blood level in the person.
A method for reducing the incidence of tobacco smoking in a human user by administration to the upper gastro-intestinal tract of a therapeutically effective amount of nicotine, said method comprising:
- (a) providing a palatably acceptable solution containing a therapeutically effective amount of nicotine, having an acidic pH, and being adapted for introduction into the user's upper gastro-intestinal tract, and including a flavoring in the nicotine solution wherein the flavoring is selected from the group consisting of sugar, coffee, beer, wine, whiskey, fruit juice, milk, soda, and combinations thereof;
- (b) administering the nicotine solution to the user so as to introduce the nicotine to the metabolism of the user, wherein the administering is free of buccal administering and free of sublingual administering;
- and
- (c) periodically repeating (b), so as to administer a therapeutically effective amount of the nicotine to the user's metabolism after the first-pass absorption to the liver so that the nicotine achieves a sufficient blood level in the user in order to reduce the need of the user to smoke tobacco.
A method for providing nicotine to a person by administration to the upper gastro-intestinal tract of a selected amount of nicotine, said method comprising:
- (a) providing a palatably acceptable solution containing a therapeutically effective amount of nicotine, having a pH less than about 5.5, and being adapted for introduction into the person's upper gastro-intestinal tract;
- (b) administering the nicotine solution to the person's upper gastro-intestinal tract so as to introduce the nicotine to the metabolism of the person;
- and
- (c) periodically repeating (b), so as to administer a selected amount of the nicotine to the person's metabolism after the first-pass absorption to the liver so that the nicotine achieves a selected blood level in the person.
A method for providing nicotine to a person by swallowing a selected amount of nicotine, said method comprising:
- (a) providing a palatably acceptable aqueous solution containing about 0.5 to about 42 milligrams of nicotine per about 300 milliliters of nicotine solution and having a pH less than about 5.5;
- (b) drinking the solution so as to introduce the nicotine to the metabolism of the person;
- and
- (c) periodically repeating (b) at least 1 time per day, so as to achieve a blood level of at least 1.5 nanograms of the nicotine per about 1 milliliter of blood in the person within about 30 to about 80 minutes of each repeating of (b).
A method for reducing the incidence of tobacco smoking in a human user by administration to the upper gastro-intestinal tract of a therapeutically effective amount of nicotine, said method comprising:
- (a) providing a palatably acceptable solution containing a therapeutically effective amount of nicotine, having a pH less than about 5.5, and being adapted for introduction into the user's upper gastro-intestinal tract;
- (b) administering the nicotine solution to the user so as to introduce the nicotine to the metabolism of the user;
- and
- (c) periodically repeating (b), so as to administer a therapeutically effective amount of the nicotine to the user's metabolism after the first-pass absorption to the liver so that the nicotine achieves a sufficient blood level in the user in order to reduce the need of the user to smoke tobacco.
A method for reducing the incidence of tobacco smoking in a human user by swallowing a therapeutically effective amount of nicotine, said method comprising:
- (a) providing a palatably acceptable aqueous solution containing about 0.5 to about 42 milligrams of nicotine per about 300 milliliters of nicotine solution and having a pH less than about 5.5;
- (b) drinking the solution so as to introduce the nicotine to the metabolism of the user;
- and
- (c) periodically repeating (b) at least 1 time per day, so as to achieve a blood level of at least about 1.5 nanograms of the nicotine per about 1 milliliter of blood in the user within about 30 to about 80 minutes of each repeating of (b).
