Abstract
Increasing knowledge into personalized medicine has demonstrated the need for individual dosing. Drug dosage forms are urgently needed enabling an individual therapy, especially for oral drug delivery. This review is focusing on approaches for solid and liquid oral dosage forms for individual dosing. The proposed dosage forms and devices may be distinguished into assembling and partition concepts and have been categorized regarding their applicability, costs, dose flexibility and potential benefits. Opportunities, challenges and further unmet needs are elaborated and critically discussed.Liquid dosage forms can be accurately dosed by novel dropping tubes or oral syringes, but less precisely by dosing spoons and cups. Breaking scored tablets into fragments show major risks such as inaccurate dosing, formation of potent dust and stability issues of the residual segments. Novel approaches are proposed for solid dosage forms enabling a flexible and appropriate therapy such as various dispensers for multiparticulate drug formulations. However, most of the proposals still have to prove their applicability in practice. Promising concepts are the Solid Dosage Pen and drug-loaded oral films which can be cut in individual sections enabling freely selectable doses. Further research and development are required for novel dosage forms and medical devices appropriate for individualized therapy.
