Title: Combination of a bronchodilator and a steroidal anti-inflammatory drug for the treatment of respiratory disorders
Abstract:Effective amounts of formoterol and/or a physiologically acceptable salt and/or solvate thereof and budesonide are used in combination for simultaneous, sequential or separate administration by inhalation in the treatment of an inflammatory respiratory disorder, such as asthma.
Inventor(s): Carling; Christer Carl Gustav (Dalby, SE), Trofast; Jan William (Lund, SE)
Assignee: Astra Aktiebolag (Sodertalje, SE)
Application Number:08/317,407
Patent Claims: 1. A medicament containing as active ingredients effective amounts of a physiologically acceptable salt of formoterol or a solvate thereof, and budesonide wherein the molar ratio of the formoterol component to the budesonide component is in the range from 1:4 to 1:60.

2. The medicament of claim 1 wherein the active ingredients are in dry powder form.

3. The medicament of claim 1 or 2 wherein the formoterol is in the form of the fumarate dihydrate.

4. A pharmaceutical composition which comprises effective amounts of a physiologically acceptable salt of formoterol or a solvate thereof, and budesonide wherein the molar ratio of the formoterol component to the budesonide component is in the range from 1:4 to 1:60, together with a pharmaceutically acceptable carrier.

5. The pharmaceutical composition of claim 4 wherein the formoterol is in the form of the fumarate dihydrate.

6. A pharmaceutical composition according to claim 4 wherein the pharmaceutically acceptable carrier is lactose.

7. A pharmaceutical composition according to claim 6 in dosage unit form.

8. A pharmaceutical composition according to claim 7 comprising 12 .mu.g formoterol fumarate dihydrate, 200 .mu.g budesonide and up to 25 mg lactose.

9. A medicament containing as active ingredients effective amounts of a physiologically acceptable salt of formoterol or a solvate thereof, and budesonide wherein the molar ratio of the formoterol component to the budesonide component is in the range from 1:1 to 1:60.

10. The medicament of claim 9 wherein the active ingredients are in dry powder form.

11. The medicament of claim 9 or 10 wherein the formoterol is in the form of the fumarate dihydrate.

12. A pharmaceutical composition which comprises effective amounts of a physiologically acceptable salt of formoterol or a solvate thereof, and budesonide wherein the molar ratio of the formoterol component to the budesonide component is in the range from 1:1 to 1:60, together with a pharmaceutically acceptable carrier.

13. The pharmaceutical composition of claim 12 wherein the formoterol is in the form of the fumarate dihydrate.

14. A pharmaceutical composition according to claim 12 wherein the pharmaceutically acceptable carrier is lactose.

15. A pharmaceutical composition according to claim 14 in dosage unit form.

16. A pharmaceutical composition according to claim 15 comprising 12 .mu.g formoterol fumarate dihydrate, 200 .mu.g budesonide and up to 25 mg lactose.

17. A method for the treatment of asthma and other inflammatory respiratory disorders which comprises administering by inhalation to a host in need of such treatment effective amounts of a physiologically acceptable salt of formoterol or a solvate thereof, and budesonide wherein the molar ratio of the formoterol component to the budesonide component is in the range from 1:4 to 1:60.

18. The method according to claim 17, wherein the effective amount of the physiologically acceptable salt of formoterol or solvate thereof is 6-100 .mu.g per day, and the effective amount of budesonide is 50-4800 .mu.g per day.

19. The method according to claim 18 wherein the effective amount of the physiologically acceptable salt of formoterol or solvate thereof is 6-48 .mu.g per day, and the effective amount of budesonide is 100-1600 .mu.g per day.

20. The method according to any one of claims 17, 18 and 19 wherein the administration is performed from a dry powder inhaler.

21. The method according to claim 20 wherein the inhaler is a Turbuhaler.TM..

22. The method according to any one of claims 17, 18 and 19 wherein the administration is performed from a metered dose inhaler.

23. The method according to any one of claims 17, 18 and 19 wherein the formoterol is in the form of the fumarate dihydrate.

24. The method according to any one of claims 17, 18 and 19 wherein the administration is performed with a nebulizer.

25. A method according to any one of claims 17, 18 and 19 wherein the formoterol component and the budesonide component are administered simultaneously.

26. The method according to any one of claims 17, 18 and 19, wherein the physiologically acceptable salt of formoterol or the solvate thereof is administered in admixture with the budesonide.

27. A method for the treatment of asthma and other inflammatory respiratory disorders which comprises administering by inhalation to a host in need of such treatment effective amounts of a physiologically acceptable salt of formoterol or a solvate thereof, and budesonide wherein the molar ratio of the formoterol component to the budesonide component is in the range from 1:1 to 1:60.

28. The method according to claim 27, wherein the effective amount of the physiologically acceptable salt of formoterol or solvate thereof is 6-100 .mu.g per day, and the effective amount of budesonide is 50-4800 .mu.g per day.

29. The method according to claim 28 wherein the effective amount of the physiologically acceptable salt of formoterol or solvate thereof is 6-48 .mu.g per day, and the effective amount of budesonide is 100-1600 .mu.g per day.

30. The method according to any one of claims 27, 28 and 29 wherein the administration is performed from a dry powder inhaler.

31. The method according to claim 30 wherein the inhaler is a Turbuhaler.TM..

32. The method according to any one of claims 27, 28 and 29 wherein the administration is performed from a metered dose inhaler.

33. The method according to any one of claims 27, 28 and 29 wherein the formoterol is in the form of the fumarate dihydrate.

34. The method according to any one of claims 27, 28 and 29 wherein the administration is performed with a nebulizer.
