摘要:
The following invention introduces a patch preparation for treating plants, whereas the patch preparations comprise a chemical layer composed of at least one agrochemically active compound, at least one adhesive and optionally, one or more additives. The components are dispersed in a matrix state on a substrate which are then introduced on the roots of the plant to be treated.

An ophthalmic solid pharmaceutical preparation for external use is disclosed which can be used to continuously administer with ease a pharmacologically active agent to ocular local tissues. The pharmaceutical preparation is a solid pharmaceutical preparation containing a pharmacologically active ingredient in a base, which may comprise an oily base, and designed to be applied by being rubbed on the surface of the skin including the surface of either of the eyelids to deliver, through the skin of the eyelids, the pharmacologically active ingredient to the local tissues of the eye located on the backside of the eyelids.
摘要:
A transdermal drug delivery device for administering 5-[(3,4-dimethoxyphenethyl) methylamino]-2-(3,4-dimethoxyphenyl)-2-isopropylvaleronitrile comprising a permeable matrix of silicone elastomer or other bioacceptable lipophilic polymer material having an effective cardiovascular affecting amount of active drug and an effective drug release promoting amount of a transport enhancing agent dispersed therein. The back of the matrix is covered with an occlusive backing and the face of the matrix is covered with a biocompatible adhesive such as a silicone adhesive also having a transport enhancing agent dispersed therein. A supply of skin permeation enhancing agent may be provided adjacent the adhesive layer such that the skin of a patient to whom the device is applied is pretreated with permeation enhancing agent. Particularly preferred skin permeation and transport enhancing agents include N,N-diethyl-m-toluamide, isopropyl myristate and similar compounds.
摘要:
A method for producing compression-melt molded product using polylactic acid powder is described. The method comprises the steps of: 1) heat-melting polylactic acid having a weight-average molecular weight of 3,000-40,000 at 140-220° C., 2) allowing the melted polylactic acid to cool down to solidify at an ordinary or a lower temperature, 3) pulverizing the solidified polylactic acid at an ordinary temperature into powder, and 4) compressing the powder or a mixture powder prepared by addition of another ingredient, e.g., a biologically active compound, to the carrier powder in a mold at an ordinary temperature to cause the polylactic acid to melt into a molded product of a predetermined shape.
摘要:
Ophthalmic adhesive preparations for percutaneous absorption to be used in treating diseases in the posterior parts of eye characterized by having a drug-containing layer which contains a drug to be delivered to the posterior parts of eye including the crystalline lens, the vitreous body, the uvea and the retina, together with a percutaneous sorbefacient comprising polyoxyethylene oleyl ether and/or isopropyl myristate uniformly dispersed in a base matrix.
