Buccal swab delivery system
Described herein is a drug product delivery device and method of delivering a drug on a swab. The drug product delivery device may include an applicator platform housed within a rigid housing. The applicator platform may be in the form of a plunger. The foil drug reservoir cap creates a fluid storage chamber disposed between the foil drug reservoir cap and the plunger. A series of fluidic channels carry fluid from the fluid storage chamber to an applicator. A frangible seal is attached to the plunger between the fluid storage chamber and the applicator. The frangible seal blocks a fluid from moving from the fluid storage chamber into the series of fluidic channels. Actuation of the plunger causes the frangible seal to be ruptured, which causes the fluid to exit the fluid storage chamber and enter into the fluidic channels. The fluidic channels carry the fluid to the applicator.
1. A drug product delivery device comprising:
a housing;
a plunger comprising a molded component with a cover film that forms a series of fluidic channels on a first elongated surface of the plunger;
a foil drug reservoir cap bonded to a second elongated surface of the plunger, wherein the foil drug reservoir cap creates a fluid storage chamber disposed between the foil drug reservoir cap and the second elongated surface of the plunger;
a frangible seal component attached to the second elongated surface of the plunger, wherein the frangible seal component blocks a fluid from moving from the fluid storage chamber into the series of fluidic channels; and
an applicator positioned at a tip of the plunger and exposed to the series of fluidic channels, wherein actuation of the plunger pushes the plunger into the housing to rupture of the frangible seal component, which causes the fluid to exit the fluid storage chamber and pass through the ruptured frangible seal component into the series of fluidic channels and into contact with the applicator.
2. The drug product delivery device of claim 1 , further comprising:
a drug storage chamber arranged on the plunger between the frangible seal component and the series of fluidic channels, the drug storage chamber storing a dry drug; and
wherein activation of the plunger causes the frangible seal component to rupture and the fluid to exit the fluid storage chamber and pass through the ruptured frangible seal component and into the drug storage chamber for mixture with the dry drug before the fluid and dry drug mixture enters into the series of fluidic channels and into contact with the applicator.
3. The drug product delivery device of claim 2 , wherein the fluid comprises a carrier fluid and a dry drug comprises a small molecule drug.
4. The drug product delivery device of claim 1 , wherein the applicator is a flock swab.
5. The drug product delivery device of claim 4 , wherein the flock swab is a sterile flock swab.
6. The drug product delivery device of claim 1 , wherein the frangible seal component comprises an overmolded rigid polypropylene part with a thermoplastic elastomer (TPE) gasket.
7. The drug product delivery device of claim 1 , wherein the housing comprises a rigid plastic housing.
8. The drug product delivery device of claim 7 , wherein the rigid plastic housing comprises a plurality of molded parts attached together.
9. The drug product delivery device of claim 1 , wherein the fluid comprises a small molecule drug.
10. The drug product delivery device of claim 1 , wherein the fluid comprises a vaccine.
11. A method of delivering a drug on a swab, the method comprising:
actuating a plunger of a drug product delivery device to push the plunger into a housing of the drug product delivery device, wherein the drug product delivery device comprises:
the plunger, wherein the plunger comprises a molded component with a cover film that forms a series of fluidic channels on a first elongated surface of the plunger,
a foil drug reservoir cap bonded to a second elongated surface of the plunger to create a fluid storage chamber disposed between the foil drug reservoir cap and the second elongated surface of the plunger,
a frangible seal component attached to the second elongated surface of the plunger to block a fluid comprising a pharmaceutically active ingredient from moving from the fluid storage chamber into the series of fluidic channels, and
an applicator positioned at a tip of the plunger and exposed to the series of fluidic channels, wherein actuating the plunger causes the frangible seal component to rupture, and the fluid to exit the fluid storage chamber and pass through the ruptured frangible seal component into the series of fluidic channels and into contact with the applicator; and
delivering, using the applicator, the drug onto a buccal surface.
12. The method of claim 11 , wherein the pharmaceutically active ingredient comprises a small molecule drug.
13. The method of claim 11 , wherein the pharmaceutically active ingredient comprises a vaccine composition.
14. The method of claim 11 , the drug product delivery device further comprises:
a drug storage chamber arranged on the plunger between the frangible seal component and the series of fluidic channels, the drug storage chamber storing a dry drug; and
wherein activation of the plunger causes the frangible seal component to rupture and the fluid to exit the fluid storage chamber and pass through the ruptured frangible seal component and into the drug storage chamber for mixture with the dry drug before the fluid and dry drug mixture enters into the series of fluidic channels and into contact with the applicator.
15. The method of claim 11 , wherein the applicator is a flock swab.
16. The method of claim 11 , wherein the applicator is a sterile flock swab.
17. The method of claim 11 , wherein the frangible seal component comprises an overmolded rigid polypropylene part with a thermoplastic elastomer (TPE) gasket.
18. The method of claim 11 , wherein the housing comprises a rigid plastic housing.
19. The method of claim 18 , wherein the rigid plastic housing comprises a plurality of molded parts attached together.
20. The method of claim 11 , wherein the fluid comprises a carrier fluid and a dry drug comprises a small molecule drug.
