81 results about "Aprotinin" patented technology

The drug aprotinin (Trasylol, previously Bayer and now Nordic Group pharmaceuticals), is a small protein bovine pancreatic trypsin inhibitor (BPTI), or basic trypsin inhibitor of bovine pancreas, which is an antifibrinolytic molecule that inhibits trypsin and related proteolytic enzymes. Under the trade name Trasylol, aprotinin was used as a medication administered by injection to reduce bleeding during complex surgery, such as heart and liver surgery. Its main effect is the slowing down of fibrinolysis, the process that leads to the breakdown of blood clots. The aim in its use was to decrease the need for blood transfusions during surgery, as well as end-organ damage due to hypotension (low blood pressure) as a result of marked blood loss. The drug was temporarily withdrawn worldwide in 2007 after studies suggested that its use increased the risk of complications or death; this was confirmed by follow-up studies. Trasylol sales were suspended in May 2008, except for very restricted research use. In February 2012 the European Medicines Agency (EMA) scientific committee reverted its previous standpoint regarding aprotinin, and has recommended that the suspension be lifted. Nordic became distributor of aprotinin in 2012.

Method and Kit for the Early Detection of Impaired Renal Status

A method and kit for identifying the presence of an early biomarker of impaired renal status following a renal event in a mammalian subject. The method typically comprises (a) providing a body fluid sample obtained from a mammalian subject following a renal event; and (b) detecting in the provided sample the presence of a protein selected from the group consisting of aprotinin, alpha-1-microglobulin (A1M), alpha-1-acid-glycoprotein (A1AG), microalbumin, and combinations thereof, the presence thereof serving as an early biomarker of a change in renal status. The method can include a kit for point-of-care detection of the early biomarker of impaired renal status. Identification of the presence or absence of the early biomarker typically directs a caregiver's therapeutic decision regarding managing treatment of the subject for impaired renal status The invention also includes a method of assessing the administration of aprotinin during cardiopulmonary bypass surgery and provides for methods where the level of aprotinin in the subject's urine directs a caregiver's therapeutic decision regarding the intra-operative administration of aprotinin.

Aprotinin-like polypeptides for delivering agents conjugated thereto to tissues

Based on our identification of a polypeptide (Angiopep-7) that is efficiently transported to cells such as liver, lung, kidney, spleen, and muscle, the invention provides polypeptides, conjugates including the polypeptides, and methods for treating diseases associated with these cell types. Unlike other aprotinin related polypeptides identified herein (including Angiopep-3, Angiopep-4a Angiopep-4b Angiopep-5, and Angiopep-6) which efficiently cross the blood-brain barrier (BBB), Angiopep-7 is not efficiently transported across the BBB.

Method of preparing a collagen sponge, a device for extracting a part of a collagen foam, and an elongated collagen sponge

A method of preparing a collagen sponge comprises mixing air into a collagen gel, so as to obtain a collagen foam which is dried. From the dried product thereby obtained, collagen sponge is obtained by isolating parts of sponge with a chamber diameter of more than 0.75 mm and less than 4 mm, or parts with an average chamber diagonal dimension of 3 mm. The collagen sponge may be used as a material for sealing wounds, possibly with a coating comprising a fibrin glue, such as a combination of fibrinogen, thrombin and aprotinin. A device for extracting a part of a collagen foam and for degenerating another part of the collagen foam to a collagen gel is disclosed. An elongated collagen sponge having a through-going hole or bore and a flexible wall may be used for re-establishing walls in a mammalian gastrointestinal funnel or trachea system.
