20110056863 | ADHESIVE PREPARATION CONTAINING DONEPEZIL, AND PACKAGE OF THE SAME - [Object] An adhesive preparation containing donepezil is provided in which adhesive layer discoloration over time is inhibited. | 03-10-2011 |
20110243998 | PATCH PREPARATION AND PRODUCTION METHOD THEREOF - The invention provides a patch preparation containing (a) a support and (b) an adhesive layer containing a drug on the surface of the support, wherein a crystal of the drug is formed in the adhesive layer immediately after application of a physical stimulation to the adhesive layer, while a crystal of the drug is formed during preservation after the physical stimulation. The patch preparation which does not require an increase in the area and thickness of an adhesive layer, achieves a sufficiently high skin permeation amount of the drug, shows good adhesiveness to skin, and permits a long-term adhesion to skin. The invention also provides a method of producing the patch preparation. | 10-06-2011 |
20120027840 | ADHESIVE PATCH AND PATCH PREPARATION - The present invention provides an adhesive patch including a backing and a pressure-sensitive adhesive layer formed on at least one surface of the backing, in which (a) a surface of the pressure-sensitive adhesive layer has a logarithmic decrement, as determined by the rigid-pendulum free-damped oscillation method, in the range of 0.03 to 0.35, and (b) the pressure-sensitive adhesive layer has a maximum shear displacement in the range of 18 μm to 1,000 μm. The present invention further provides a patch preparation containing a drug. The adhesive patch and the patch preparation according to the present invention are reduced in skin irritation during wear. | 02-02-2012 |
20130064868 | COMPOSITION FOR ENHANCING TRANSDERMAL ABSORPTION OF A DRUG AND PATCH PREPARATION - The problem of the present invention is to provide a composition for enhancing transdermal absorption of a drug, which shows a sufficiently high enhancing effect on transdermal absorption of a drug, particularly, a composition for enhancing transdermal absorption of a drug, which shows a sufficiently high enhancing effect on transdermal absorption of an acidic drug. | 03-14-2013 |
20130064869 | COMPOSITION FOR ENHANCING TRANSDERMAL ABSORPTION OF A DRUG AND PATCH PREPARATION - The problem of the present invention is to provide a composition which shows a sufficiently high enhancing effect on transdermal absorption of a drug, particularly, a composition which shows a sufficiently high enhancing effect on transdermal absorption of a drug in a patch preparation. | 03-14-2013 |
20130064875 | COMPOSITION FOR ENHANCING TRANSDERMAL ABSORPTION OF A DRUG AND PATCH PREPARATION - The problem of the present invention is to provide a composition for enhancing transdermal absorption of a drug, which shows a sufficiently high enhancing effect on transdermal absorption of an acidic drug. | 03-14-2013 |
20130084325 | MANUFACTURING METHOD OF PATCH PREPARATION - The invention provides a method of manufacturing a patch preparation comprising (a) pouring a composition for forming an adhesive layer into a container having a concave part with a shape corresponding to a patch preparation to be manufactured, wherein the composition contains a drug, an adhesive polymer, and an organic solvent; (b) removing the organic solvent from the composition through drying to form a drug-containing adhesive layer in the concave part; and (c) laminating a support on the drug-containing adhesive layer to provide the patch preparation comprising a support and the drug-containing adhesive layer formed on one surface of the support. | 04-04-2013 |
20140083890 | PACKAGING MATERIAL AND PACKAGE STRUCTURE USING THE SAME - An object of the present invention is to provide a packaging material that is capable of long term storage by preventing adsorption or transfer of an easily oxidizable component and an oily component in an adhesive of a patch to the packaging material, and also preventing discoloration and decrease in drug effect due to oxidization. The present invention provides the packaging material for a patch including: an inner layer made of polyethylene terephthalate having heat sealing properties; an oxygen-absorbing layer that includes an oxygen-absorbing resin having an unsaturated alicyclic structure as an oxygen-absorbing part; and an oxygen barrier layer made of aluminum foil as an outer layer. | 03-27-2014 |
20140255466 | COMPOSITION FOR ENHANCING TRANSDERMAL ABSORPTION OF DRUG AND PATCH PREPARATION - The present invention relates to a composition for enhancing transdermal absorption of a drug, containing a polyvalent alcohol having 3 to 8 carbon atoms, an organic acid having 2 to 20 carbon atoms, and a higher alcohol having 12 to 20 carbon atoms, and a patch preparation containing a support and a drug-containing adhesive layer containing the composition on one surface of the support. | 09-11-2014 |
