Definitions
- the invention relates to a new medical use of ⁇ l-acidic glycoprotein (AAG) or orosomucoid.
- AAG ⁇ l-acidic glycoprotein
- ⁇ l-acidic glycoprotein (AAG) or orosomucoid is a protein found in plasma with a molecular weight of approx.40,000 and an isoelectric point of 2.7. It is the most soluble and stable of all plasma proteins, which is probably due to its extremely high carbohydrate content of around 40% (30-50%).
- AAG consists of a single polypeptide chain with 183 amino acids and has 2 disulfide bridges. Localized in the first half of the peptide chain are 5 carbohydrate chains, which consist of approximately 14% hexoses, 14% hexosamines, 1% fucose and 11-15% N-acetylneuraminic acid (sialic acid). AAG occurs in different forms (2 A, I S, 1 FI), both in terms of the polypeptide chain and in terms of the carbohydrate chains.
- AAG ⁇ l-acidic glycoprotein
- orosomucoid The properties and biological functions of ⁇ l-acidic glycoprotein (AAG) or orosomucoid are described in review articles by Schmid (in “The Plasma Proteins: Structure Function and Genetic Control”, Vol. 1 (1975), Academic Press, Ed. Frank A. Putnam , 2 nd Edition, pages 193-228) and Kremer et al. (Pharmacological reviews 40 (1988), pages 1-47).
- a positive effect of ⁇ l-acidic glycoprotein (AAG) in inflammatory reactions has been described in medicine (Denko et al., Agents and Actions 15, 5/6 (1984), 539-540).
- Libert et al. J. Exp. Med. 180 (1994), 1571-1575
- Muchitsch et al. (WO 98/40087) showed "the use of human ⁇ l-acid glycoprotein for the production of a pharmaceutical preparation" for the treatment of disorders of the blood circulation or the microcirculation of a non-inflammatory type.
- the role of ⁇ l-acidic glycoprotein in the transport of predominantly basic drugs in plasma is also described (see Kremer et al.).
- ⁇ l-acidic glycoprotein therefore functions alongside human serum albumin (HSA) as one of the most important transport proteins, whereby the state of charge of the drug is decisive for binding: basic substances are preferably transported by ⁇ l-acidic glycoprotein, e.g. Methadone, diisopyramide, dipyridamole, lignocaine, progesterone, warfarin, chlorpromazine, quinidine, etc.
- AAG is also proposed for the acute detoxification of drug poisoning, e.g. for the treatment of overdoses on quinine, lignocaine, propanolate or tricyclic anti-depressants, such as amitriptyline, desipramine or nortriptyline (W097 / 32893).
- Detoxification treatments of this type use the strong binding of such drugs to AAG, but have the disadvantage that they significantly prolong the actual elimination of the drugs from the body. This includes also described for AAG:
- methadone binds to both human serum albumin (HSA) and ⁇ -acid glycoprotein (AAG) (see, for example, Romach et al. In Clin. Pharmacol. Ther. 29: 2 (1981), 211-217), it is assumed that since methadone is not only free in the plasma but also bound to these proteins, the plasma exchange thus removes both fractions.
- HSA human serum albumin
- AAG ⁇ -acid glycoprotein
- Garrido et al. J. Pharm Pharmacol. 48: 3 (1996) 281-284 showed an increase in the AAG concentration in plasma after oral administration of morphine to rats, as well as in acute inflammation (Gomez et al., Gen. Pharmacol 26: 6 ( 1995) 1273-1276). In both cases, the methadone binding also changed, which is why the authors recommend adjusting the methadone dose both during the weaning process and when acute inflammation occurs.
- Albumin has the ability to accelerate drug elimination whether or not it binds to albumin.
- ⁇ l-acidic glycoprotein slows down the elimination of drugs that it can bind, while it has no influence on the elimination of non-binding drugs.
- PA plasma exchange
- Methadone 15 3 1.9 0.5 0.5 0.4 0.3 0.5
- the object of the present invention is therefore to provide a medicament with which drug withdrawal is decisively improved over the measures known in the prior art. can be set.
- Such medication therapy should at least bring about a comparable - if not better - favorable influencing and acceleration of the weaning process than the sole plasmapheresis, while keeping the patient in good physical and mental condition if possible.
- This object is achieved according to the invention by the use of AAG for the manufacture of a medicament for influencing and accelerating drug withdrawal.
- HSA was to be regarded as an essential protein for such withdrawal modulation.
- the treatment could be ended after a total of 3 days. If one compares the course of the two treatments, it is noticeable that the withdrawal symptoms of the 1st treatment could be almost completely avoided in the 2nd patient - which was already greatly alleviated and shortened compared to usual weaning procedures. The one-time plasmapheresis and hemodilation could also have been omitted, since they were only a product of the original treatment plan.
- Preparations of individual subclasses of ⁇ l-acid glycoprotein fall under this invention as well as genetically engineered ⁇ l-acid glycoprotein.
- the preparation is prepared as an isotonic, storage-stable infusion solution and is released as such or as a lyophilisate.
- the dose for the indicated indication depends on the general condition of the patient.
- the total amount of 10 mg to 1 g / kg, preferably 50-250 mg / kg body weight, can be administered either as a single dose or divided into several doses.
- the application can be done in all ways, preferably diluted infusions IV.
- Human AAG which is produced from plasma, is preferably used according to the invention, but recombinant human AAG also has advantageous properties compared to other AAG preparations which can be used according to the invention, in particular if it has been produced in cells which are capable of a suitable one To provide glycosylation patterns at the AAG (e.g. mammalian cells).
- compositions with more than 10% pure ⁇ l-acid glycoprotein, preferably more than 75%, preferably those in which more than 90% of the total protein is present as ⁇ l-acid glycoprotein, are preferably used.
- the rest can consist of human serum albumin (HSA) and other plasma proteins.
- the pharmaceutical preparation is preferably stabilized, i.e. stabilizers, in particular sodium caprylate, are added to increase the storage stability and stability during heat treatment.
- Fig. 1 drug withdrawal by means of plasma exchange
- Fig. 2 Drug withdrawal using AGG
- methadone drug is taken because drug addicts are very sensitive to pain and restless after taking their drug.
- the patient signs a declaration of consent to the cessation therapy and only then is he admitted to the intensive care unit.
- a central venous catheter is placed in the intensive care unit and blood is drawn.
- the mild hypoxia was corrected with the addition of oxygen using a mask.
- Intensive care measures mean that the patient is restless, sweaty, disoriented and additionally contaminated. This threatening picture of the condition took about 10 hours with the constant use of nursing staff and doctors. After these difficult hours, the patient's condition is stable and he was able to sleep through the night unobtrusively.
- the patient is in a very good general condition, mobile, completely normal and walks in the park.
- Parenteral therapy midazolam and clonidine, was switched to oral.
- Clonidine 0.5 mg and midazolam 7.5 mg for 6 hours.
- the additional parenteral nutrition is switched off and the cava catheter is removed.
- Glycoprotein (according to the invention): 19.9.97 / ZO
- the patient is stable in circulation, cooperative, placement of a venous cannula and a peripheral venous catheter on the left.
- a venous cannula Immediately after admission start sedation with Dormicum 0.4 mg / kg / d, clonidine 0.02 mg / kg / d. Dormicum bolus on admission.
- the patient is stable in circulation, afebrile, cooperative, no physical withdrawal symptoms. Only the nicotine withdrawal worries him.
- the Dormicum-Clonidine dosage is reduced to half; it only needs to be increased slightly in the night after midnight due to chest problems; afterwards the patient is free of symptoms again.
