  • Publication number: 20090163457
    Abstract: The invention relates to codrugs having improved properties, methods for preparing and administering them, and methods of formulating and administering the codrugs as pharmaceutical preparations. In certain embodiments, the codrugs can be locally administered to deliver the constituent biologically active compound in a sustained-release fashion, reducing systemic concentrations of the biologically active compound.

  • Publication number: 20080107720
    Abstract: The present invention provides pharmaceutical compositions for topical delivery comprising a suitable carrier and a codrug capable of penetrating, or being transported across, the dermis. The codrug according to the invention comprises a first constituent moiety linked to a second constituent moiety, wherein the second constituent moiety is the same as, or different from, the first constituent moiety. The first and second constituent moieties are so linked that they are easily transported into or across the dermis, into the skin, or into the blood or lymphatic system, and are reconstituted in vivo to form the first and second constituent moieties.

  • Publication number: 20070213390
    Abstract: A compound that contains at least two independently active pharmacological moieties, either covalently conjoined through a physiologically labile linker or ionically associated. One pharmacological moiety is an HMGCoA reductase inhibitor (such as a statin). Another pharmacological moiety is an angiotensin converting enzyme inhibitor.

  • Publication number: 20070112050
    Abstract: The invention provides a compound comprising a first pharmacological moiety connected to at least a second pharmacological moiety through a physiologically labile linker, or a salt thereof. The invention also provides a method of reducing cardiovascular disease or cardiovascular disease-related conditions in an individual. The method involves administering to an individual with cardiovascular disease an effective amount of a compound, in which the compound has a first pharmacological moiety linked to a second pharmacological moiety, and the compound or either or both of the constituent pharmacological moieties acts to reduce, treat, or prevent cardiovascular disease. The compounds of the invention can be delivered in a drug delivery device.

  • Publication number: 20030022876
    Abstract: A pharmaceutically active inventive compound comprises two independently active analgesic moieties covalently conjoined through a physiologically labile linker. A preferred embodiment comprises an opioid, such as morphine, covalently linked to at least one analgesic compound selected from the group consisting of an opioid or a non-opioid compound through a physiologically labile linker. Suitable covalent linkers are covalently bonded to the two independently active analgesic compounds through one or more lactone, lactam, or sulfonamido linkages. Suitable linkers include endogenous carboxylate, amido, and sulfonamido moieties, and exogenous moieties that form the aforementioned lactone, lactam or sulfonamido linkages.
