Definitions

  • the invention relates to a combination of acetylsalicylic acid (component A) with an alpha-glucosidase inhibitor (component B), for the prevention of cardiovascular diseases.
  • the compound of component A is well known to those skilled in the art. It is acetylsalicylic acid, which is primarily used for secondary (Antiplatelet Trialists' CoUaboration: CoUaborative overview of randomized trials of antiplatelet therapy. I: Prevention of death, myocardial infarction, and streike by prolonged antiplatelet therapy in various categories of patients. Brit. Med. J 1994, 308, 81-106) but also for primary prevention of cardiovascular diseases (US Preventive Services Task Force: Aspirin for the primary prevention of cardiovascular events: recornmendation and rationale. Ann. Intern. Med. 2002, 136, 157 -160).
  • Compounds of component B are known to the person skilled in the art as substances regulating blood sugar levels. They are alpha-glucosidase inhibitors that include acarbose. Acarbose has been described in many publications and textbooks as one of the standard therapies for the treatment of type 2 diabetes mellitus. (Lebovitz, et. Al, alpha-glucosidase inhibitors as agents in the treatment of diabetes, Diabetes Reviews 1998; 6 (2): 132-45)
  • the present invention relates to the combination of acetylsalicylic acid as component A with an alpha-glucosidase inhibitor as component B for the prevention of cardiovascular diseases.
  • Prevention means both primary and secondary prevention.
  • primary prevention is the protection of patients from a first cardiovascular disease that results in organ damage.

  • Combinations in the sense of the invention are not only dosage forms which contain all components (so-called fixed combinations) and combination packs which contain the components separately from one another, but also components which are applied simultaneously or at different times, provided that they are used for treatment or prophylaxis same disease.
  • components A and B can be converted into the customary formulations in a known manner, which can be liquid or solid formulations. Examples are tablets, dragées, pills, capsules, granules, aerosols, syrups, emulsions, suspensions, juices.
  • the combinations according to the invention are well tolerated and are effective even in low doses. the most diverse formulation variants can be implemented.
  • the two individual components A and B do not necessarily have to be taken at the same time, but a delayed intake can be advantageous in order to achieve optimal effects.
  • the two components are each in separate containers, which are e.g. can be tubes, vials or blister packs.
  • Such separate packaging of the two components in a common primary packaging means is also referred to as a kit.
  • Fixed combinations are also suitable as a further formulation variant for the combinations according to the invention.
  • “Fixed combination” is to be understood here to mean medicinal forms in which the two components are present together in a fixed quantitative ratio.
  • Such fixed combinations can be implemented, for example, as oral solutions, but are preferably solid oral medicinal preparations, for example capsules or tablets.
  • the combinations according to the invention are dosed up to 3 times a day; preference is given to those combinations which allow 1 ⁇ + 2 ⁇ daily application.

  • the active ingredients of components A and B are particularly suitable for being formulated in a fixed combination in the form of a fixed oral dosage form. It is generally known that the reliability of compliance (compliance) in patients is crucially dependent on the factors number of dosage forms per time of administration and size and weight of the (fixed oral) dosage form. Therefore, the number of different medicines to be taken separately should be as small as possible (advantage of a fixed combination), and the size and weight of a fixed oral dosage form should be as small as possible with full therapeutic potency in order to ensure that the patient can take the medication properly to be as comfortable as possible.
  • This enables fixed combinations in the form of solid oral pharmaceutical formulations to be implemented with a minimal size and minimal weight.
  • the fixed combinations according to the invention accordingly offer the highest possible patient compliance and thereby decisively improve the safety and reliability of a therapy.
  • the drug release can be controlled by combining the two components A and B and modifying the composition or functionality. For example, by delaying the release of active ingredient (retardation) of a component, the above-mentioned decoupling of the onset of action can also be achieved in fixed combinations.
  • the fixed oral dosage forms listed here are manufactured according to the general standard procedures. Ingredients are those that are pharmaceutically accepted and physiologically harmless, for example: as fillers cellulose derivatives (e.g. microcrystalline cellulose), sugar (e.g. lactose), sugar alcohols (e.g. ma nitol, sorbitol), inorganic fillers (e.g. calcium phosphates), binders (e.g.
