    • A compound with topical anesthetic properties is incorporated in polymeric material suitable for forming products useful in the medical arts. A hydrophobic anesthetic compound is used which is more soluble in the polymer than in water so that a quantity of anesthetic compound can be stored in solution in the polymer and not be washed out by aqueous bodily fluid. This results in metered diffusion of drug to the local tissue in an amount sufficient to maintain effective anesthesia of the local tissue while avoiding the associated problems of systemic drug delivery. Examples of medical products include anesthetizing cuffs, films or balloons disposed on catheters or tubes; anesthetic (122) coated sutures (120) or the like; adherent anesthetizing bandages, strips or patches, or in the form of an anesthetizing plastisol or foam suitable for topical application. Methods of manufacturing the compound/polymer are also disclosed.
    • 具有局部麻醉剂性质的化合物掺入适于形成有用于医学领域的产品的聚合物材料中。 使用比在水中更易溶于聚合物的疏水麻醉化合物,使得一定量的麻醉化合物可以储存在聚合物中的溶液中,并且不会被水体液洗掉。 这导致药物对局部组织的计量扩散,其量足以维持局部组织的有效麻醉,同时避免了全身药物递送的相关问题。 医疗产品的实例包括麻醉袖口,设置在导管或管上的膜或气囊; 麻醉剂(122)涂层缝合线(120)等; 粘附麻醉绷带,条或贴片,或以适于局部应用的麻醉增塑溶胶或泡沫的形式。 还公开了制备化合物/聚合物的方法。

    • Drug delivery polymer systems include hydrophobic polymer and a drug that has an aromatic ring. The system comprises, on a carrier (10), a layer (12) comprising the pressure sensitive adhesive having solids in which a drug is substantially soluble, a non-adhesive polymeric resin distributed uniformly in non-particulate manner through the adhesive, in which the drug is substantially soluble, and drug. Another delivery system comprises a non-adhesive layer (14) of polymeric resin in which a drug component is substantially soluble and an adjoining adhesive band (18) arranged to hold the non-adhesive layer against the skin. In both, the drug comprises at least 10 % by weight of the drug-containing layer, preferably in excess of 20 %, or 30 % or 40 % by weight. It is discovered that concentrations in excess of 50 % and 60 % can be achieved in effective formulations. The layer can be thin so that, despite high concentration no more than about 30mg drug per inch square is present, preferably less than 20mg or 10 mg per inch square. In embodiments that achieve a high concentration, the drug component comprises at least two drugs, one of which is soluble in the other, a solution of the drugs in the quantities present in the layer having a melting temperature below room temperature, and lower than the melting temperature of either drug alone. A congealed plastisol layer comprising tetracaine, lidocaine and polyvinyl chloride, is particularly effective for topical anesthetic. Methods of manufacture and preparatory compositions have now been disclosed.
    • 药物递送聚合物体系包括疏水性聚合物和具有芳香环的药物。 该系统在载体(10)上包括包含具有药物基本可溶于其中的固体的压敏粘合剂的层(12),非粘合剂聚合物树脂以非颗粒状方式均匀分布通过粘合剂,其中 该药物是基本可溶的和药物。 另一种输送系统包括其中药物组分基本可溶的聚合物树脂的非粘合层(14)和布置成将非粘附层保持在皮肤上的邻接粘合带(18)。 在两种药物中,药物含有至少10重量%的含药层,优选超过20重量%,或者30重量%或40重量%。 发现在有效制剂中可以达到超过50%和60%的浓度。 该层可以是薄的,使得尽管高浓度,每平方英寸不超过约30mg药物,优选小于20mg或10mg每平方英寸。 在达到高浓度的实施方案中,药物组分包含至少两种药物,其中一种可溶于另一种,药物溶液存在于熔点低于室温的层中,并且低于 只有任一种药物的解链温度。 包含丁卡因,利多卡因和聚氯乙烯的凝胶增塑溶胶层对局部麻醉剂特别有效。 现在已经公开了制造方法和制备组合物。
