  • Patent number: 6117447
    Abstract: A percutaneous absorption type preparation comprising a support and a plaster layer laminated thereon, which composes tulobuterol in a proportion of not less than 5 wt % in a dissolution state and an adhesive. The preparation of the present invention retains the active ingredient, tulobuterol, at a high concentration in a complete dissolution state in the plaster layer. Therefore, it is free of time-course changes in drug releasing property and adhesive property caused by precipitation of drug crystals with the lapse of time. The inventive preparation is superior in percutaneous absorption of the drug, particularly percutaneous absorption rate at the initial stage of the administration; shows superior duration of efficacy by maintaining effective blood concentration for a long time; and is associated with less changes with the lapse of time in adhesive property such as adhesion to the skin.

A gelling agent may be optionally added at up to 20% by volume. The chemical system is preferably administered via a multidose transdermal drug patch assembly which includes a drug-impervious support impressed to form a series of compartments. Each compartment is a reservoir for a unit dose of a drug active to be transdermally administered. The support is adhesively secured to the skin of a patient.

The inventive method comprises administering a lipophilic compound in conjunction with a structured glyceride component characterized in that at least 40% of the glyceride species have: (i) about 33 to 70 wt. % of acyl moieties having 4 to 12 carbon atoms; (ii) about 30 to 67 wt. % of acyl moieties having more than 12 carbon atoms; and (iii) an equivalent carbon number greater than 30 and less than 48. This invention also relates to compositions suitable for administrating to an animal comprising a lipophilic compound and a structured glyceride component characterized in that at least 40% of the glyceride species have: (i) about 33 to 70 wt. % of acyl moieties having 4 to 12 carbon atoms; (ii) about 30 to 67 wt. % of acyl moieties having more than 12 carbon atoms; and (iii) an equivalent carbon number greater than 30 and less than 48.

  • Patent number: 6011022
    Abstract: The invention is directed to methods and pharmaceutical compositions for the topical administration of analgesic drugs which affects peripheral muscarinic receptors such as neostigmine. In particular, the invention relates to topical administration of an analgesic agent, e.g., neostigmine, optionally in admixture with a skin- or mucosal-specific penetration enhancer, to produce a localized analgesic effect in inflamed or non-inflamed skin or mucosal tissue, and without a transdermal or transmucosal migration of the agent, e.g., into the central nervous system.

  • Patent number: 6004927
    Abstract: A method for increasing bioavailability of an orally administered hydrophobic pharmaceutical compound, which comprises orally administering the pharmaceutical compound to a mammal in need of treatment with the compound concurrently with a bioenhancer comprising an inhibitor of a cytochrome P450 3A enzyme or an inhibitor of P-glycoprotein-mediated membrane transport, the bioenhancer being present in sufficient amount to provide bioavailability of the compound in the presence of the bioenhancer greater than the bioavailability of the compound in the absence of the bioenhancer.

  • Patent number: 6004578
    Abstract: The present invention is directed to the transdermal administration of at least one drug together with a suitable amount of a permeation enhancer comprising monoalkyl ethers of polyethyleneglycol and their alkyl or aryl carboxylic acid esters and carboxymethyl ethers. The invention includes a transdermal drug delivery device comprising a matrix adapted to be placed in drug- and- permeation enhancer- transmitting relation with a skin site. The matrix contains sufficient amounts of the permeation enhancer and drug, in combination, to continuously administer drug to the systemic circulation of a patient at a therapeutically effective rate. The invention is also directed to compositions and methods for transdermal administration of at least one drug together with a permeation enhancer of this invention, alone or in combination with other enhancers.

  • Patent number: 5998483
    Abstract: Methods are provided to prepare a variety of tissues in a pathology-stable form keyed to the use of an aqueous solution of C.sub.2-6 dialdehyde and/or dialdehyde addition products, including the group consisting of glyoxal and/or glutaraldehyde in an amount sufficient to prevent autolysis and other degradative changes in various tissues. The said solution is capable of treating a tissue so as to maintain the tissue in a condition suitable for pathology and/or other experimental observation. The stabilizing solution is also useful to prepare parts or whole animals and plants in an anatomically preserved state for a prolonged period of time, and compositions useful in that method.
