Abstract

The invention relates to a device for use in the clinical/therapeutical field for the patient-individual optimization of the dosage and/or the dosage scheme of a drug based on rational, mathematical models which take into consideration possible physiological variations that are due to the illness or other particularities of the patient and the interaction with co-drugs that are administered at times close to each other. The invention also relates to the supply of said drug dose by means of a dosage device.

Claims

1. An apparatus for providing a medicament dose comprising an input unit (1) for inputting individual patient information (101);

a calculation unit (2) for calculating the medicament dose and, if appropriate, the optimum dose planned, and an automatic apparatus, connected thereto, for dosing of medicaments (3),

wherein the medicament dose is calculated in the calculation unit (2) by means of a rational mathematical simulation model (205) using physiological information (201), pathological information (202), medicament-specific information (203) and, if appropriate, information relating to additionally supplied medicaments (204) which information is available in the calculation unit (2).

2. The apparatus as claimed in claim 1, wherein the input unit (1) is a handheld device for manually inputting the individual patient information (101) or a smart-card reader for reading the individual patient information (101).

3. The apparatus as claimed in claim 1, wherein the rational mathematical model (205) is selected from allometric scaling functions of physiologically-based pharmacolinetic models.

4. The apparatus as claimed in claim 3, wherein the rational mathematical model (205) is a dynamically generated physiologically-based pharmacokinetic/pharmacodynamic simulation model.

5. The apparatus as claimed in claim 1, wherein the individual patient information (101) is selected from age, sex, race, body weight, body size, body mass index, lean body mass fat free body mass, gene expression data, debilitations, allergies, medication, kidney function and liver function.

6. The apparatus as claimed in claim 1, wherein the physiological information (201) is selected from age, sex, race, body weight, body size, body mass index, lean body mass fat free body mass, gene expression data, debilitations, allergies, medication, kidney function and liver function.

7. The apparatus as claimed in claim 1, wherein the pathological information (202) is selected from age, sex, race, body weight, body size, body mass index, lead body mass fat free body mass, gene expression data, debilitations, allergies, medication, kidney function and liver function.

8. The apparatus as claimed in claim 1, wherein the medicament-specific information (203) is selected from lipophilia, free plasma fraction, blood plasma ratio, distribution volume, clearance, type of clearance, clearance proportions, type of excretion, dose plan, transporter substrate, PD end point and side effects.

9. The apparatus as claimed in claim 1, wherein the information relating to additionally supplied medicaments (204) is selected from lipophilia, free plasma fraction, blood plasma ratio, distribution volume, clearance, type of clearance, clearance proportions, type of excretion, dose plan, transporter substrate, PD end point and side effects.

10. The apparatus as claimed in claim 1, wherein the information is transmitted from the input unit (1) to the calculation unit (2) and/or from the calculation unit (2) to the apparatus for dosing of medicaments (3) without the use of wires.

11. A method for calculating a medicament dose on the basis of individual patient information (101), wherein the calculation of the medicament dose is carried out in a calculation unit by a rational mathematical simulation model (205) using physiological information (201), pathological information (202), medicament-specific information (203) and, if appropriate, information relating to additionally supplied medicaments (204) which are available in the calculation unit (2).
