5. A formulation as claimed in claim 3 wherein the anticholinergic medicament is ipratropium or a salt thereof.

6. A formulation as claimed in claim 4 wherein the anticholinergic medicament is ipratropium or a salt thereof.

7. A formulation according to claim 1 wherein the medicament is present in an amount of 0.1 to 1% w/w based on the weight of formulation.

8. A formulation according to claim 2 wherein the medicament is present in an amount of 0.1 to 1% w/w based on the weight of formulation.

9. A method of treating respiratory disorders which comprises administration by inhalation of an effective amount of a pharmaceutical aerosol formulation according to claim 1.

10. A method of treating respiratory disorders which comprises administration by inhalation of an effective amount of a pharmaceutical aerosol formulation according to claim 2.

11. A method of treating respiratory disorders which comprises administration by inhalation of an effective amount of a pharmaceutical aerosol formulation according to claim 5.

12. A method of treating respiratory disorders which comprises administration by inhalation of an effective amount of a pharmaceutical aerosol formulation according to claim 6.

13. A pharmaceutical aerosol formulation which consists essentially of particulate medicament which is salmeterol or a physiologically acceptable salt or solvate thereof and an anticholinergic medicament in combination and 1,1,1,2-tetrafluoroethane as propellant, which formulation contains less than 0.0001% w/w of surfactant.
