Die Erfindung betrifft eine pharmazeutische Zusammensetzung mit verbesserter Wirkung und Nerträglichkeit zur Behandlung von Typ-II-Diabetes mellitus, welche eine Kombination von Metformin und/ oder dessen pharmazeutisch unbedenklichen Salzen und Glimepirid und/ oder Acarbose und wahlweise Poly(dimethyl)siloxan als wirksame Komponente enthält.The invention relates to a pharmaceutical composition with improved activity and tolerability for the treatment of type II diabetes mellitus, which contains a combination of metformin and / or its pharmaceutically acceptable salts and glimepiride and / or acarbose and optionally poly (dimethyl) siloxane as an effective component .
Diabetes mellitus Typ II (ΝIDDM = non-insulin-dependent diabetes mellitus) zeigt sich in einer verminderten Insulinwirkung bzw. in einer Insulinunempfindlichkeit. Hauptsächlich tritt diese Diabetes-Form im Erwachsenenalter auf und wird unterschieden in Typ A mit normalem und Typ B mit erhöhtem Körpergewicht. Diese Krankheit hat eine erbliche Grundlage und wird durch überkalorische Ernährung begünstigt. Gewichtsreduktion kann zu einer Verbesserung der Stoffwechsellage führen (Typ IIB). Die Behandlung wird bisher mittels Diät und/ oder Einnahme oraler Antidiabetika, bei Komplikationen und Sekundärversagen mittels der Verabreichung von Insulin durchgeführt.Type II diabetes mellitus (ΝIDDM = non-insulin-dependent diabetes mellitus) manifests itself in a reduced insulin effect or insulin insensitivity. This type of diabetes mainly occurs in adulthood and is divided into type A with normal and type B with increased body weight. This disease has a hereditary basis and is favored by over-caloric nutrition. Weight loss can lead to an improvement in the metabolism (type IIB). The treatment has hitherto been carried out by diet and / or by taking oral antidiabetic agents, in the case of complications and secondary failure by means of the administration of insulin.
Die Aufgabe der vorliegenden Erfindung ist es nun, eine in der Wirksamkeit und Verträglichkeit verbesserte pharmazeutische Zusammensetzung zur Behandlung von Typ II Diabetes mellitus bereitzustellen, welche bei Sekundärversagen, Komplikationen und erfolgloser Diätbehandlung mit Erfolg eingesetzt werden kann und die Patienten-Compliance durch eine geringere Einnahmehäufigkeit verbessert.The object of the present invention is now to provide a pharmaceutical composition for the treatment of type II diabetes mellitus which is improved in efficacy and tolerability and which can be used successfully in the event of secondary failure, complications and unsuccessful diet treatment and improves patient compliance through a lower frequency of ingestion .
Es wurde nun überraschenderweise gefunden, daß die Kombination von Metformin und/ oder dessen pharmazeutisch unbedenklichen Salzen mit Glimepirid und/ oder Acarbose und wahlweise Poly(dimethyl)siloxan bei Sekundärversagen, Komplikationen und/ oder einer erfolglosen Diätbehandlung eine überlegene therapeutische Wirksamkeit aufweist. Die häufig bei der Monotherapie dieser Wirkstoffe und bei der Verwendung der anderen gängigen Antidiabetika auftretenden gastrointestinalen Nebenwirkungen sowie die Gefahr der Hypoglykämie und der Gewichtszunahme werden durch Verwendung der erfindungsgemäßen Zusammmensetzung wesentlich verringert bzw. vermieden, wobei die antidiabetische Wirkung verstärkt wird. Gegenüber den, gemäß dem Stand der Technik, bekannten und eingesetzten Antidiabetika wird durch die erfindungsgemäße Kombination eine vereinfachte, erfolgsversprechendere Therapie mit einer verbesserten Wirksamkeit auch für kompliziertere Diabetes-Fälle vom Typ II gewährleistet.It has now surprisingly been found that the combination of metformin and / or its pharmaceutically acceptable salts with glimepiride and / or acarbose and optionally poly (dimethyl) siloxane has superior therapeutic efficacy in the event of secondary failure, complications and / or unsuccessful dietary treatment. The often with the monotherapy of these active ingredients and with the use of the other common antidiabetic gastrointestinal side effects and the risk of hypoglycemia and weight gain are significantly reduced or avoided by using the composition according to the invention, the antidiabetic effect being enhanced. Compared to the antidiabetic agents known and used according to the prior art, the combination according to the invention ensures simplified, more promising therapy with improved effectiveness, even for more complicated type II diabetes cases.
Metformin, ein lJ-Dimethylbiguanid, ist ein orales Antidiabetikum, welches zur Behandlung von NIDDM verwendet wird. Metformin reduziert den Blutzuckerspiegel schwe unktmäßig durch Hemmung der hepatischen Gluconeogenese sowie durch Reduktion der Glucoseresorption und durch Verringerung der peripheren Insulinresistenz. Im Gegensatz zu den ebenfalls sehr häufig verwendeten Sulfonylharnstoffen stimuliert Metformin nicht die Insulinfreisetzung aus den ß-Zellen in der Bauchspeicheldrüse, sondern verbessert die Sensibilität des Gewebes für Insulin. Zusätzlich reduziert dieser Wirkstoff den Lipid- und Cholesterinspiegel im Serum. Die Bioverfügbarkeit beträgt 50-60 %. Gastrointestinale Beschwerden sind die üblichen Nebenwirkungen, die bei der Einnahme von Metformin mehr oder weniger stark auftreten.Metformin, a 1J-dimethylbiguanide, is an oral anti-diabetic used to treat NIDDM. Metformin reduces the blood sugar level swiftly by inhibiting hepatic gluconeogenesis as well as by reducing glucose absorption and by reducing peripheral insulin resistance. In contrast to the sulfonylureas, which are also used very frequently, metformin does not stimulate the release of insulin from the ß cells in the pancreas, but rather improves the sensitivity of the tissue to insulin. This active ingredient also reduces serum lipid and cholesterol levels. The bioavailability is 50-60%. Gastrointestinal complaints are the usual side effects that occur more or less strongly when taking metformin.
Glimepirid ist ein Sulfonylharnstoff, der zur Behandlung von Typ II Diabetes mellitus verwendet wird. Er senkt den Blutzuckerspiegel, indem er die Insulinfreisetzung aus den ß- Zellen der Bauchspeicheldrüse und den Glucosetransport und die Glucosemetabolisierung. in den Muskel- und Fettzellen außerhalb der Bauchspeicheldrüse anregt. Eine Dephosphorylierung und Aktivierung des Schlüsselenzyms des Glucosetransportes und der Glucosemetabolisierung, verursacht durch die Glycosylphosphatidylinositol-spezifische Phospholipase C, stellt den außerhalb der Bauchspeicheldrüse stattfindenden Wirkmechanismus von Glimepirid dar. Relativ häufig tretenden Hypoglykämie und Gewichtszunahme sowie gastrointestinale Beschwerden als Nebenwirkungen auf.Glimepiride is a sulfonylurea used to treat type II diabetes mellitus. It lowers blood sugar levels by reducing insulin release from the ß cells of the pancreas and the glucose transport and metabolism. stimulates in the muscle and fat cells outside the pancreas. Dephosphorylation and activation of the key enzyme of glucose transport and glucose metabolism, caused by the glycosylphosphatidylinositol-specific phospholipase C, is the mechanism of action of glimepiride that takes place outside the pancreas. Hypoglycaemia and weight gain, which occur relatively frequently, and gastrointestinal side effects and gastrointestinal effects.
Acarbose wirkt als α-Glykosidasehemmer, d.h. durch Acarbose wird mittels einer kompetitiven Hemmung der α-Glykosidase die enzymatische Aufspaltung von Kohlehydraten verzögert. Es wird somit die Resorption von Glucose aus dem Darm verzögert. Bauchschmerzen, Durchfälle und Verdauungsstörungen sind die sehr häufig auftretenden unerwünschten Nebenwirkungen.Acarbose acts as an α-glycosidase inhibitor, ie acarbose delays the enzymatic breakdown of carbohydrates by means of a competitive inhibition of α-glycosidase. The absorption of glucose from the intestine is thus delayed. Abdominal pain, diarrhea and indigestion are the very common side effects.
