1-7. (canceled)
A method of administering a pharmaceutical product in the form of an aerosol, said method comprising:
- (a) generating a constant flow of air by a the use of a nebulization pump that is operative during inspiration and expiration phases of a respiratory cycle;
- (b) generating a pre-established flow of air by a resistant pump wherein said nebuluization pump and said resistant pump are connected to a common duct an said common duct adapted for conveying an air flow to aerial tracts of a patient;
- (c) providing a nebulization basin containing a pharmaceutical product to be nebulized by said pre-established flow of air in said common duct;
- (d) reducing said pre-established air flow at said resistant pump to provide a flow of air during all expiration phases of a respiratory cycle where said air flow is lower during the expiration phase than during the inspiration phase.
