  • Publication number: 20040087479
    Abstract: Elevated levels of homocysteine have been implicated as an important risk factor for cardiovascular and other diseases. A composition for decreasing levels of plasma homocysteine and a method for administering the composition are provided, the composition containing dextromethorphan (DM), folic acid and vitamins B6 and B12. The composition provides a synergistic therapeutic effect so that lower amounts of the above ingredients may be employed to minimize any undesirable side effects caused by the use of high levels of a component such as DM. Preferred compositions for cardiovascular diseases further include lecithin, vitamin E, betacarotene, procyanidins/flavonoids, trimethylglycine, garlic oil and minerals. Other compositions for treating glaucoma include bilberry, bioflavonoids and beta-carotene and for treating tardive dyskinesia include an antioxidant such a grape seed extract and pine bark extract, lecithin and oligomeric proanthocyanidins.

  • Publication number: 20030114673
    Abstract: Compounds of formula (E) (wherein X and Y, which may be the same or different, each represents Cl, Br or F) and tautomers thereof have been found to have enhanced platelet count reducing properties. Also provided are methods for synthetically making the compounds of formula (E) and pharmaceutically acceptable addition salts thereof and a method of reducing the platelet count in patient by administering to the patient a platelet reducing effective amount of a compound of formula (E) preferably together with a pharmaceutically acceptable carrier. A pharmaceutical composition is also provided which contains a compound of formula (E) as the active ingredient together with pharmaceutically acceptable excipients. Further provided is a compound of formula (E) for use in therapy and the use of a compound of formula (E) for preparing a medicament for reducing platelet count in a patient.

  • Patent number: 6541043
    Abstract: A composition and method for treating Attention Deficit/Hyperactivity Disorder (ADHD) is provided which can be used both with and without ethical drugs now used to treat ADHD. The composition contains dimethylaminoethanol (DMAE), omega 3-fatty acids, betaine, oligomeric proanthocyanidins (OPC), folic acid, vitamins C, E, B12, B6, B5 and beta-carotene and minerals (calcium, magnesium, zinc and selenium). Ethical drugs such as amphetamines, methylphenidate HCl and pemoline are known to control ADHD, but each has significant side effects when used in their therapeutic dose. When combining the composition with such ethical drugs, the amount of the ethical drug can be lowered below a level which causes undesirable side effects which is an important feature. Preferred compositions contain one or more of lecithin, choline, 5-hydroxytryptophan, tyrosine, Reishi Extract, Kava Extract, Gingko, Ginseng and St. John's Wort.
