Abstract

A device for the intranasal delivery of a medicament regimen to the nasal membranes for the treatment of such conditions as rhinitis.

Claims

1. A device for delivering medication to a patients'"'"' nasal membranes and minimizing systemic side effects from administering the same, comprising:

a housing having first and second chambers;

said first chamber having a first internal compartment and a first removable canister of a first medication housed in said first compartment;

said second chamber having a second internal compartment and a second removable canister of a second medication housed in said second compartment;

said housing further having at least one outlet nozzle selected from (a) at least one common outlet nozzle in fluid communication with said canisters of medication and means for independently allowing aerosol spray from either of said first or second canisters to be discretely released through an exit nozzle to said common outlet nozzle and (b) a separate outlet nozzle in fluid communication with each of said first and second canisters of medication and means for independently allowing aerosol spray from one of said canisters to be discretely released through an exit nozzle to said separate outlet nozzle associated therewith;

means for delivering aerosol directly onto a patient'"'"'s nasal membranes and minimizing systemic side effects from said administration; and

means for indicating at least one of (a) a prescribed dispensing sequence of medicament from said aerosol canisters received in said chambers, (b) the medicament contained in each of said canisters, and (c) patient symptoms to be treated by each of the medicaments released as aerosols from said canister.

2. The device as defined by claim 1, wherein said common outlet nozzle is positionally adjustable between each of said exit nozzles.

3. The device as defined by claim 1, wherein the canisters are oriented essentially parallel to each other, and further comprising toggle means rotatably mounted on said housing for selectively activating the dispensing of medicament from a particular canister.

4. The device as defined by claim 3, comprising indicia on said toggle of the prescribed dispensing sequence.

5. The device as defined by claim 1, wherein the canisters are disposed in a linear, parallel, angular, or circular relationship with respect to each other.

6. The device as defined by claim 1, further comprising a cap adapted to fit over and operably cover at least one of said outlet nozzles.

7. The device as defined by claim 1, comprising at least said indicia on the housing of the prescribed dispensing sequence.

8. The device as defined by claim 1, wherein the medicaments are selected from the group consisting of adrenergically acting decongestants, anti-cholinergic agents, topical buffering compounds and lavaging solutions, mast cell stabilizers, corticosteroid anti-inflammatory agents, and mixtures thereof.

9. The device as defined by claim 1, wherein the medicaments comprise a decongestant and an anti-inflammatory agent.

11. The device as defined by claim 9, wherein the medicaments are selected from the group consisting of adrenergically acting decongestants, anti-cholinergic agents, topical buffering compounds and lavaging solutions, mast cell stabilizers, corticosteroid anti-inflammatory agents, and mixtures thereof.

12. The device as defined by claim 9, wherein the medicaments comprise a decongestant and an anti-inflammatory agent.

10. A method for facilitating patient compliance in the equential intranasal administration of at least two medicaments to a patient in need thereof, which method comprises:

providing a housing having first and second chambers;

providing in said first chamber a first internal compartment and a first removable canister of a first medication housed in said first compartment;

providing in said second chamber a second internal compartment and a second removable canister of a second medication housed in said second compartment;

providing on said housing at least one outlet nozzle selected from (a) at least one common outlet nozzle in fluid communication with said canisters of medication and providing means for independently allowing aerosol spray from either of said first or second canisters to be discretely released through an exit nozzle to said common outlet nozzle and (b) a separate outlet nozzle in fluid communication with each of said canisters of medication and providing means for independently allowing aerosol spray from each of said first and second canisters to be discretely released through an exit nozzle to said separate outlet nozzle associated therewith;

providing means for delivering aerosol directly onto a patient'"'"'s nasal membranes and minimizing systemic side effects of said administration; and

providing means for indicating at least one of (a) a prescribed dispensing sequence of medicament from said aerosol canisters received in said chambers, (b) the medicament contained in each of said canisters, and (c) patient symptoms to be treated by each of the medicaments released as aerosols from said canister.
