- the active ingredients of components A and B are particularly suitable to be formulated in a fixed combination in the form of a solid peroral dosage form. It is well known that patient compliance depends critically on the number of dosage forms per administration and the size and weight of the (solid peroral) dosage form. Therefore, both the number of different medicines to be taken separately should be as low as possible (the advantage of a fixed combination on), as well as the size and weight of a solid peroral dosage form to be as small as possible with full therapeutic potency, to make the intake as comfortable as possible for the patient. This allows fixed combinations in the form of solid peroral pharmaceutical formulations with minimal size and minimum weight realized. Accordingly, the fixed combinations according to the invention offer the highest possible patient compliance and thereby decisively improve the safety and reliability of a therapy.
