Abstract

Disclosed herein are novel procedures, systems and excipient solutions for in situ provision of a contrast media at a user defined concentrations. An automated procedure according to embodiments of the current invention provides increased user safety, flexibility and user friendliness.

First claim

The invention claimed is:

1. An automated system for the production of a patient-tailored dose of a contrast agent close to or next to a patient wherein said system comprises:
(i) one or more sealed containers comprising constituents for the preparation of said contrast agent in a dilutable form and wherein each of said one or more sealed containers comprises an information carrier providing data relating to said constituents and wherein said one or more sealed containers comprise a first container containing an API of said contrast agent, a second container containing one or more excipients and a third container containing a diluent;
(ii) a receiving device for receiving said one or more sealed containers;
(iii) a conduit for bringing the constituents of said one or more sealed containers together to result in diluted constituents;
(iv) a conduit for conveying said diluted constituents into a product sealed container;
(v) an electronic memory of a computing device for receiving data wherein said data comprises said data relating to said constituents and patient-specific data; and,
(vi) software instructions to calculate the amounts of each constituent required for said dose and to direct the preparation of said dose based on said data relating to said constituents and said patient-specific data.

2. The automated system as defined in claim 1 wherein said contrast agent is an X-ray contrast agent or a magnetic resonance imaging (MRI) contrast agent.

3. The automated system as defined in claim 1 wherein said contrast agent is an X-ray contrast agent.

4. The automated system as defined in claim 3 wherein said X-ray contrast agent is an iodinated x-ray contrast agent.

5. The automated system as defined in claim 4 wherein the active pharmaceutical ingredient (API) of said iodinated x-ray contrast agent is a 2,4,6-triiodinated-benzene ring.

6. The automated system as defined in claim 5 wherein said 2,4,6-triiodinated-benzene ring is a monomeric 2,4,6-triiodinated-benzene ring.

7. The automated system as defined in claim 5 wherein said 2,4,6-triiodinated-benzene ring is a dimeric 2,4,6-triiodinated-benzene ring.

8. The automated system as defined in claim 1 wherein said contrast agent is an MRI contrast agent.

9. The automated system as defined in claim 8 wherein the API of said MRI contrast agent is a metal chelate comprising a cheland or a derivative thereof and a paramagnetic metal ion.

10. The automated system as defined in claim 9 wherein said paramagnetic metal ion is an ion of a metal of atomic number 21 to 29, 42, 44 and 57 to 71.

11. The automated system as defined in claim 9 wherein said paramagnetic metal ion is selected from Cr, V, Mn, Fe, Co, Pr, Nd, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu.

12. The automated system as defined in claim 9 wherein said chelate is an acyclic or cyclic polyaminocarboxylate.

13. The automated system as defined in claim 12 wherein said chelate is one of DTPA, DTPA-BMA, DOTA and DO3A.

14. The automated system as defined in claim 1 wherein said sealed container is a capsule.

15. The automated system as defined in claim 1 wherein said information carrier is an electronic tag, a barcode, an RFID tag, a QR code, or an optically-readable code.

16. The automated system as defined in claim 1 wherein said system is fluidly connected to an injector system for the administration of the patient-tailored dose to a patient.

17. A method for the production of a patient-tailored dose of a contrast agent wherein said method comprises using the system as defined in claim 1 and said method comprises the following steps:
(a) providing data to said electronic memory of the computing device wherein said data comprises data relating to the constituents of said one or more sealed containers and patient-specific data; and,
(b) applying software instructions to said data to calculate the amounts of each constituent required for said patient-tailored dose and to direct said automated system to prepare said dose.
