  • Publication number: 20040132826
    Abstract: A once-a-day oral milnacipran modified release formulation has been developed. The formulation comprises an extended release dosage unit (optionally containing the immediate release portion) coated with delayed release coating. The milnacipran composition, when administered orally, first passes through the stomach releasing from zero to less than 10% of the total milnacipran dose and then enters the intestines where drug is released slowly over an extended period of time. The release profile is characterized by a 0.05-4 hours lag time period during which less than 10% of the total milnacipran dose is released followed by a slow or extended release of the remaining drug over a defined period of time. The composition provides in vivo drug plasma levels characterized by Tmax at 4-10 hours and an approximately linear drop-off thereafter and Cmax below 3000 ng/ml, preferably below 2000 ng/ml, and most preferably below 1000 ng/ml.

  • Publication number: 20040106681
    Abstract: The present invention provides a method to treat neurological disorders. The method includes, e.g., administering higher daily dosages of anti-depressant. The higher daily dosages result in an improved efficacy of the drug, the maintenance of a positive patient toleration, the maintenance of a positive patient safety profile (e.g., dose limiting toxicity), a suitable peak plasma concentration (Cmax) of drug, and/or a once-a-day (QD) as opposed to twice-a-day (BID) administration. Applicant have discovered that increased daily dosages anti-depressant that would normally evoke adverse effects can be administered without the negative patient tolerability (i.e., adverse reactions) by escalating dosages over time. Such escalation dosages provide more efficacious amounts of anti-depressant than would otherwise be permitted. Similarly, higher levels of circulating drug are possible in patients by administering the compound in divided doses over the course of a day rather than once a day.

  • Publication number: 20040034101
    Abstract: Methods for the prevention or treatment of a typical depression secondary to pain (DSP) have been developed. The method generally involves administering an effective amount of a monoamine re uptake inhibitor to treat or prevent symptoms of DSP. In a preferred embodiment, a therapeutically effective amount of a dual serotonin norepinephrine reuptake inhibitor (SRNI) compound of a specific type, or a pharmaceutically acceptable salt thereof is administered. The most preferred SNRI compounds are non-tricyclic SNRIs, wherein serotonin reuptake inhibition is greater than norepinephrine reuptake inhibition; and NSRIs, wherein norepinephrine reuptake inhibition is greater than serotonin reuptake inhibition. The most preferred compound is milnacipran or a bioequivalent or pharmaceutically acceptable salt thereof. Other preferred compounds are duloxetine and venlafaxine or a bioequivalent or pharmaceutically acceptable salt thereof.
