  • Patent number: 8802656
    Abstract: A new pharmaceutical composition is disclosed comprising a purified phospholipid-selective and/for nonselective non-steroidal, anti-inflammatory drug associated complex and methods for making and using same. A screening method for identifying compounds that form phospholipid associated complexes is also disclosed.
    Type: Grant

  • Publication number: 20080051373
    Abstract: Parenteral preparations of phospholipid-associated anti-inflammatories (PL-AIs) are described to treat pain/inflammation, with reduced gastrointestinal (GI) toxicity. The PL-AIs can be composed of phosphatidylcholine (“PC”) associated with non-steroidal anti-inflammatory drugs (“NSAIDs”). To prepare the PL-AIs, a phospholipid is mixed with an NSAID in a polar solvent, solvent is removed, suspended in an aqueous medium and sterilized by filtration or other acceptable method. Alternatively, the phospholipid can be mixed with an injectable preparation of an NSAID. The PL-AIs, and particularly PC associated with the NSAIDs, indomethacin, ibuprofen or diclofenac are useful for treating Patent Ductus Arteriosus in low birth weight infants to reduce the incidence of GI injury that may be manifest as Necrotizing Enterocolitis (NEC) or Spontaneous Intestinal Perforation (SIP).

  • Publication number: 20080020056
    Abstract: A unique composition of a 5-amino salicylic acid (5ASA) and a phospholipid is disclosed for treating Inflammatory Bowel Disease (IBD), where the composition can be a mixture, a molecular association complex or a covalent compound of 5ASA and a reactive phospholipid covalently bonded together via a diazo linkage and to methods for administering the compositions to treat symptoms of IBD.

  • Publication number: 20050058699
    Abstract: A filter sterilized composition of a phospholipid and an anti-inflammatory pharmaceutical is disclosed, where the anti-inflammatory pharmaceutical is a nonsteroidal, anti-inflammatory drug (NSAID), a cyclooxygenase 2 (COX-2) inhibitor or a mixture thereof. A method for preparing these sterile compositions is also disclosed and includes a filtration step through a sterilizing filtration membrane. Methods for using these sterilized compositions to treat accident and battle field injuries or treatment of injuries to the nerve system especially in unconscious patients via injection, topical administration, or according to an administration protocol.

  • Publication number: 20040077604
    Abstract: A novel pharmaceutical composition is provided by which nonsteroidal anti-inflammatory drugs (NSAIDs) are added directly to phospholipid-containing oil such as lecithin oils or to a bio-compatible oil to which an phospholipid has been added to make a NSAID-containing formulation that possess low gastrointestinal (GI) toxicity and enhanced therapeutic activity to treat or prevent inflammation, pain, fever, platelet aggregation, tissue ulcerations and/or other tissue disorders. The composition of the invention are in the form of a non-aqueous solution, paste, suspension, dispersion, colloidal suspension or in the form of an aqueous emulsion or microemulstion for internal, oral, direct or topical administration.

  • Patent number: 5955451
    Abstract: Disclosed are compositions comprising non-steroid anti-inflammatory drugs (NSAID'S) complexed with zwitterionic, neutral phospholipids, or both, having reduced gastrointestinal irritating effects and enhanced antipyretic, analgesic, and antiinflammatory activity. Also disclosed are improved methods of using the complexes for treating fever, inflammation, and preventing platelet aggregation. In some embodiments, the anti-pyretic activity of sub-therapeutically used amounts of NSAID's are enhanced to elicit anti-pyretic activity in vivo when associated (noncovalently) with zwitterionic phospholipids, such as dipalmitoyl phosphatidyl choline. Methods and compositions useful for enhancing the therapeutic activity of non-steroidal anti-inflammatory agents in the presence of anti-secretory agents are also discussed.
