  • Patent number: 6649187
    Abstract: 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.

  • Patent number: 5376383
    Abstract: 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.

  • Patent number: 4837166
    Abstract: A method of assaying primary amines or cyanide is disclosed. The process is carried out by reacting a substituted or unsubstituted naphthalene-2,3-dicarboxaldehyde or o-phthalaldehyde, reactive with primary amines and cyanide, with cyanide ions and at least one primary amine to form an adduct amenable to fluorometric or electrochemical assaying techniques. The adduct is then fluorometrically or electrochemically assayed.Also disclosed are 1-cyano-benz[f]isoindole adducts.
