Patent number: 6649187Abstract: The invention provides a method and device for administering an amine drug, such as [S-(R,S)]-2-[4-[[(4-methyl)piperazin-1-yl]carbonyl]phenoxy]-3,3-diethyl-N-[1-(3,4-methylenedioxyphenyl)butyl]-4-oxo-1-azetidinecarboxamide), in a sustained release dosage form. The invention includes a pharmaceutical composition and dosage form containing a polyalkylamine polymer and an amine drug. The polyalkylamine polymer is a hydrogel that forms hydrated particles when exposed to an aqueous environment. When mixed with the amine drug in the core of a coated tablet, the polyalkylamine polymer controls the release of the amine drug into an aqueous environment of use. The hydrated particles of the polymer together with the amine drug are released from the tablet core through plural apertures in the surrounding coat.Type: GrantFiled: February 12, 2002Date of Patent: November 18, 2003Assignee: Bristol-Myers Squibb Pharma CompanyInventors: Munir A. Hussain, Arnold J. Repta

Patent number: 6185453Abstract: This invention relates to novel methods and devices for iontophoretically administering therapeutic doses of integrin receptor antagonists in a controlled manner through the skin. Such integrin receptor antagonists include but are not limited to antagonists of the IIb/IIIa and &agr;v&bgr;3 integrins and related cell surface adhesive protein receptors. The present invention includes iontophoretic delivery devices comprising integrin inhibitors. Such methods and devices are useful, alone or in combination with other therapeutic agents, for the treatment of thromboembolic disorders, angiogenic disorders, inflammation, bone degradation, cancer metastasis, diabetic retinopathy, restenosis, macular degeneration, and other conditions mediated by cell adhesion and/or cell migration and/or angiogenesis.Type: GrantFiled: June 18, 1997Date of Patent: February 6, 2001Assignee: DuPont Pharmaceuticals CompanyInventors: Munir A. Hussain, Arnold J. Repta

Patent number: 5376383Abstract: The instant invention is directed to a method for enhancing the lowering of plasma cholesterol level in a subject in need thereof which comprises the time-controlled administration of a nontoxic therapeutically effective amount of an HMG-CoA reductase inhibitor to said subject which surprisingly affords an equivalent or improved reduction of plasma cholesterol levels while significantly reducing the amount of HMG-CoA reductase inhibitor circulating in the bloodstream of the subject as compared to the same parameters when the oral administration of a conventional rapid release dosage form is utilized.Type: GrantFiled: February 1, 1993Date of Patent: December 27, 1994Assignee: Merck & Co., Inc.Inventors: Alfred W. Alberts, Edward M. Scolnick, Arnold J. Repta
