##STR00003##

wherein R.sup.6 and R.sup.7 each represents a hydrogen atom or the like, and n.sup.4 represents an integer from 1 to 6; n.sup.1 represents an integer from 0 to 4; and n.sup.2 represents an integer from 1 to 4, provided that the case where n.sup.1 is 0 and n.sup.2 is 1 is excluded, and a composition which contains the cationic lipid and a nucleic acid, or the like.

The invention relates to the compounds of formula I and formula II or its pharmaceutical acceptable polymorphs, solvates, enantiomers, stereoisomers and hydrates thereof. The pharmaceutical compositions comprising an effective amount of salts of formula I or formula II; and methods for treating or preventing multiple sclerosis may be formulated for oral, buccal, rectal, topical, transdermal, transmucosal, intravenous, parenteral administration, syrup, or injection. Such compositions may be used to treatment of neurodegenerative diseases and psoriasis.

Provided are an oral delivery composition including oxaliplatin, a water-soluble anticancer agent, and a preparation method thereof, including forming an ionic complex with a bile acid derivative, which is an oral absorption promoter, and oxaliplatin, and incorporating it into the inner aqueous phase of a water-in-oil-in-water (w/o/w) multiple nanoemulsions, thereby obtaining the oral delivery composition with improved oral bioavailability of oxaliplatin, a water-soluble anticancer agent, avoiding the inconvenience and problems of injection, improving patient compliance, and reducing medical costs.

Complexes of neridronic acid, in an acid or a salt form, with amino acids, can be used to treat or alleviate pain or related conditions, such as complex regional pain syndrome.

Treatment of neurodegenerative diseases with copper nanoclusters (CuNCs), where the neurodegenerative diseases include Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), spinocerebellar ataxia (SCA), and glaucoma.

The present invention relates to compounds of Formulas I-IV, which are salts of special lipid mediators of inflammation, compositions containing same, and methods of using same in the treatment of various diseases and disorders characterized by chronic or excessive inflammation, or both. Provided are pharmaceutical compositions adapted to deliver the compounds the lower gastrointestinal tract and methods of using same as monotherapy in the treatment of inflammatory diseases or disorders of the lower gastrointestinal tract, and in combination therapy with 5-aminosalicylate.

The present disclosure provides a chlorhexidine-cyclamate complex having a formula [C.sub.22H.sub.32Cl.sub.2N.sub.10][C.sub.6H.sub.12NO.sub.3S].sub.2 having antibacterial and antiplaque properties, together with oral care compositions comprising the complex, and methods of making and using these complexes and compositions.

Pharmaceutical formulations containing lipoic acid derivatives and ion pairs thereof are described. The pharmaceutical formulations are useful in the treatment of medical disorders, such as cancer.

The present invention relates to an ionic complex comprising a cationic polypeptide and an anionic excipient selected from: a PEG-carboxylic acid; a fatty acid having 10 or more carbon atoms; an anionic phospholipid; and a combination thereof. The invention also relates to a pharmaceutical composition comprising the ionic complex of the invention and a pharmaceutically acceptable carrier. The cationic polypeptide of the ionic complex has pharmacological activity and the complex can provide a more desirable pharmacokinetic profile for the cationic polypeptide of the complex as compared to the cationic polypeptide alone following administration. As such, the invention also relates to the use of the ionic complex and pharmaceutical composition comprising same to treat a subject suffering from a disease or disorder that is responsive to the cationic polypeptide of the ionic complex.

Disclosed are a pharmaceutical composition for anionic drug delivery, and a preparation method therefor, the pharmaceutical composition for anionic drug delivery containing: an anionic drug as an active ingredient; a cationic compound; an amphiphilic block copolymer; and a polylactate, wherein the anionic drug formed a complex with the cationic lipid, and the complex is encapsulated within a micelle structure formed by the amphiphilic block copolymer and the polylactate.
