an electronic control system for controlling the release of contents from the first and at least one further medicament container.

2. A medicament dispenser according to claim 1, wherein the first medicament component and the at least one further medicament component are non-identical.

3. A medicament dispenser according to claim 1, comprising the first medicament container and only one further medicament container.

4. A medicament dispenser according to claim 1, wherein said first release means and said at least one further release means are independently operable.

5. A medicament dispenser according to claim 1, wherein said first release means and said at least one further release means are operable in coupled fashion.

6. A medicament dispenser according to claim 1, wherein any or either of the first and the at least one further medicament containers are provided to the medicament dispenser as reversibly removable refills.

7. A medicament dispenser according to claim 1, wherein the electronic control system includes input means for inputting control commands thereto.

8. A medicament dispenser according to claim 1, wherein the electronic control system includes a diagnostic system for collecting diagnostic information relating to patient disease condition.

9. A medicament dispenser according to claim 8, wherein the electronic control system and diagnostic system are integral.

10. A medicament dispenser according to claim 8, wherein the diagnostic system is separate from the medicament dispenser and communication means are provided to enable communication of data between the diagnostic system and the electronic control system.

11. A medicament dispenser system according to claim 1, additionally comprising an electronic data management system integral with or in communication with the electronic control system.

12. A medicament dispenser according to claim 11, wherein the electronic data management system comprises a memory for storage of data;

a microprocessor for performing operations on said data; and

a transmitter for transmitting a signal relating to the data or the outcome of an operation on the data.

13. A medicament dispenser according to claim 11, wherein the electronic data management system additionally comprises a data input system for user input of data to the electronic data management system.

14. A medicament dispenser according to claim 11, additionally comprising a visual display unit for display of data from the electronic data management system to the patient.

15. A medicament dispenser according to claim 11, additionally comprising a datalink for linking to a local data store to enable communication of data between the local data store and the electronic data management system.

16. A medicament dispenser according to claim 1, wherein the first medicament container and/or the at least one further medicament container comprise a reservoir and a meter for metering medicament from said reservoir.

17. A medicament dispenser according to claim 16, wherein the meter comprises at least one metering cavity or chamber.

18. A medicament dispenser according to claim 17, wherein the or each metering chamber is reversibly moveable into fluid communication with the reservoir for metering therefrom.

19. A medicament dispenser according to claim 1 to 18, additionally comprising mixing means for mixing the released medicament components prior to their delivery to the patient as a combination product.

20. A medicament dispenser according to claim 19, wherein the mixing means comprises a mixing chamber including inlets for receiving medicament form the first medicament container and at least one further medicament container;

and an outlet for delivery of combination medicament product for delivery to the patient.

21. A medicament dispenser according to claim 1, additionally comprising variable release means responsive to the electronic control system for varying the amount of medicament product releasable from each medicament container.

22. A medicament dispenser according to claim 21, wherein the variable release means includes an timing control system for controlling the time of release of contents from the first and at least one further medicament container.
