The present invention is drawn to combinations of pharmaceutical agents having similar chemical and/or pharmacological properties, wherein the combinations maximize the therapeutic effect of the drug while minimizing their adverse effects. The methods and compositions of the invention are particularly useful in the treatment of obesity and related conditions which involves treating a subject with a sympathomimetic agent (e.g., phentermine or a phentermine-like drug) or bupropion in combination with an anti-epileptic agent (e.g., topiramate, zonisamide), CB1 antagonists (e.g., rimonabant), or a 5HT_2C-selective serotonin receptor agonist, (e.g., lorcaserin) for the treatment of obesity and related conditions. The invention also features kits for use in the practice of these novel therapies.

Compositions, and methods of use thereof, are provided for the prevention or treatment of side effects associated with the use of drugs that act as 5HT2/5HT3 serotonin receptor antagonists and alpha-2 adrenergic receptor antagonists (5HT2/5HT3 antagonist/alpha-2 antagonist). The method involves using dopamine-releasing compounds, such as amantadine, anticonvulsants, such as zonisamide, or dopamine/norepinephrine reuptake inhibitors, such as bupropion, in combination with 5HT2/5HT3 antagonist/alpha-2 antagonists, such as mirtazapine, to reduce the excessive daytime drowsiness and/or weight gain associated with 5HT2/5HT3 antagonist/alpha-2 antagonist use for the treatment of disorders, such as, depression, schizophrenia, anxiety disorders, sleep-related breathing disorders, insomnia, migraine headache, chronic tension-type headache, hot flashes, lower back pain, neuropathic pain and functional somatic syndromes. Formulations of dopamine-releasing compounds or anticonvulsants with 5HT2/5HT3 antagonist/alpha-2 antagonists are provided. In particular embodiments, combination therapy with mirtazapine and zonisamide provides relief from chronic low back pain, while reducing or avoiding side effects associated with monotherapy with mirtazapine or zonisamide.

The present invention relates generally to methods of treating obesity and minimizing metabolic risk factors associated therewith using, for example, zonisamide or other weight loss-promoting anti-convulsant either alone or in combination with bupropion or metabolites thereof or other compound that enhances the activity of norepinephrine and/or dopamine via uptake inhibition or other mechanism.

The present invention is directed to novel codrugs comprising bupropion or hydroxybupropion and an opioid antagonist or an opioid agonist joined together by chemical bonding. The codrugs provide a significant increase in the transdermal flux across human skin, as compared to the basic opioid antagonist or opioid agonist.

Described are pharmaceutical compositions comprising bupropion, metformin, and at least one pharmaceutically acceptable carrier or excipient. Another aspect of the present invention relates to a method of treating a patient suffering from obesity or needing to lose weight, comprising the step of co-administering to said patient a therapeutically effective amount of bupropion and metformin. In certain embodiments, an aforementioned method is practiced in conjunction or tandem with a medical procedure or the use of a medical device or both.

The present invention is drawn to novel topiramate compositions as well as methods for effecting weight loss, e.g., in the treatment of obesity and related conditions, including conditions associated with and/or caused by obesity per se. The present invention features an escalating dosing regimen adapted for the administration of topiramate and optionally a sympathomimetic agent such as phentermine or bupropion, in the treatment of obesity and related conditions.

The present invention discloses the application of bakuchiol compound in preparing medicine for treating psychogenic diseases and neurogenic diseases. Extracorporeal experiment and animal experiment show that the bakuchiol compound can suppressing dopamine transport protein, noradrenalin transport protein and 5-hydroxy tryptamine transport protein selectively, and no influence on gamma-aminobutyric acid transport protein and L-glytamic acid transport protein, no cytotoxicity, and antidepressant effect higher than available antidepressant medicine amfebutamoe hydrochloride. Therefore, the bakuchiol compound has excellent marketability in preparing medicine for treating psychogenic diseases and neurogenic diseases.

Methods and compositions are disclosed utilizing the optically pure (+)-isomer of bupropion to assist in smoking cessation, for treating smoking and nicotine addiction, and for treating pain, including, but not limited to, chronic pain, neuropathetic pain and reflex sympathetic dystrophy, and other disorders such as narcolepsy, chronic fatigue syndrome, fibromyalgia, seasonal affective disorder and premenstrual syndrome, while avoiding adverse affects associated with racemic bupropion.

The invention provides a kit for detecting anti-depressant drugs in serum and plasma by liquid chromatography tandem mass spectrometry.
