To provide effective and appropriate therapy, careful planning is necessary, or even mandatory. The therapeutic options have to be assessed with regard to the current state of knowledge about efficacy and safety as well as patient-specific individual factors. Planning should consider dosing scheme, combination of active substances and vehicles, safety control, off-label use if necessary, and include measures to insure patient compliance. This approach makes it possible to clearly explain the therapy with the patient, and therefore consolidates the acceptance of the therapy by patient and physician.
