10. Inhaler according to claim 7, further comprising an inhaler housing, wherein the actuating lever has a pressure position and a resting position between which the actuating lever is pivotable, and wherein the actuating lever is movable toward the housing from the resting position into the pressure position.

11. Inhaler according to claim 6, wherein the actuating lever is configured to increase a force that acts on an actuating section of the actuating lever such that the increased force tensions the tensioning device.

12. Inhaler according to claim 6, wherein the lever gear is configured such that, with a force acting on an actuating section, and with increasing movement of the actuating lever in an actuating direction of the actuating lever, an increasing force results that acts on the tensioning device.

13. Inhaler according to claim 6, wherein at least one of the lever gear and the actuating lever is configured in such a way that a force that acts on an actuating section results in an increased force on the tensioning device due to said at least one of the lever gear and the actuating lever.

14. Inhaler according to claim 4, wherein the actuating lever has a short load lever arm, and a long force lever arm, and wherein the short lever arm corresponds at least essentially to a lever arm of the elbow lever.

15. Inhaler according to claim 1, wherein the pressure generator is configured to at least one of pressurize and spray a pharmaceutical agent preparation by energy stored in the tensioning device.

16. Inhaler according to claim 1, wherein the pressure generator has a pump device, which is axially movable by the lever gear by which the tensioning device can be tensioned and which is configured to convey a pharmaceutical agent preparation out of a discharge nozzle in the case of a movement of the pump device caused by the tensioning device.

17. Inhaler according to claim 6, wherein the lever gear has an arm which is hinged on a first end of the actuating lever so as to form an elbow lever, and wherein the arm comprises a second end facing away from the first end which is configured to produce tensioning of the tensioning device.

18. Inhaler according to claim 6, wherein a first end of the lever gear has an arm which is hinged on the actuating lever and wherein the arm comprises a second end facing away from the first end and which is configured to produce tensioning of the tensioning device.

19. Inhaler according to claim 18, wherein the arm is hinged on the actuating lever in an area of the actuating lever between a pivot point of the actuating lever on a housing of the inhaler and an actuating section of the actuating lever such that the arm is one of fork-shaped and L-shaped.

20. Inhaler according to claim 16, wherein the lever gear has an arm is hinged on a first end of the actuating lever so as to form an elbow lever, and wherein the arm comprises a second end facing away from the first end which is configured to produce tensioning of the tensioning device;

wherein the pump device has a receptacle or a stop for the arm, wherein the tensioning mechanism is configured so that the arm acts on the pump device in a tensioning movement of the lever gear, so that a force can be introduced into the tensioning device.

21. Inhaler according claim 1, wherein the inhaler has a triggering device, wherein, when tensioning of the tensioning device is concluded, the tensioning device is securable against movement.

22. Inhaler according to claim 10, wherein the tensioning mechanism has a reset element which is configured to tension or move the actuating lever back into the rest position.

30. Inhaler according to claim 3, wherein at least one of the lever gear and the actuating lever is configured in such a way that a force that acts on an actuating section results in an increased force on the tensioning device due to said elbow lever.

23. Inhaler for insertion into a nostril of a horse, comprising:

a pressure generator having a tensioning device for driving the pressure generator, wherein the tensioning device is tensionable by moving a tensioning part from a first resting position of the tensioning part into a second pressurizing position of the tensioning part, and

wherein the inhaler is configured to at least one of release the tension device when tensioned, trigger the pressure generator and discharge of a pharmaceutical agent preparation by moving the tensioning part from the second position into the first position, and moving the tensioning part from the first position toward the second position again.

24. Inhaler according to claim 23, wherein the inhaler has a triggering device which is configured to enable or to prevent the releasing or triggering of the tensioning device depending on a tensioning state of the tensioning device.
