Filed:

Mar 29, 2001

Appl. No.:

09/819742

Inventors:

Cary Robinson - Radnor PA, US

International Classification:

A61C005/04
A61C017/02

US Classification:

433/089000, 433/080000

Abstract:

A single dose dental applicator which includes a capsule with a first end and a second is disclosed. Extending outwardly from the first end of the capsule is an elongated nozzle. The end of the nozzle has a tip which is frangible. The second end of the capsule has a flat portion which acts as a handle. A quantity of dental varnish is housed within the capsule. In order to use the applicator, the dentist breaks the tip of the nozzle and inserts the nozzle into the cavity. The dentist then holds the handle and squeezes the capsule, thereby releasing the varnish housed therein. The quantity of varnish housed within the capsule is sufficient to line one tooth. The capsule is then discarded.

International Classification:

A61K009/22
A61K009/26

US Classification:

424/468000, 424/470000

Abstract:

Provided is a slow-release delivery vehicle for delivering at least one active ingredient into a film coating, comprising a population of stable, homogeneously-dispersed, porous polymeric or co-polymeric beads having a network of pores, wherein the at least one active ingredient is held within the bead particles and within the network of pores and slowly released by internal flow, and wherein the network of pores is substantially non-collapsible upon removal of the active ingredient. The porous co-polymer bead preparation comprises a continuous aqueous phase solution containing a monomeric mixture of at least one polyvinylaromatic monomer and at least one porogen forming a network that comprising (i) macropores; (ii) mesopores; (iii) micropores; and (iv) gel porosity. Also provided are methods of preparing the porous co-polymer bead preparation; and for its use as a slow-release delivery vehicle.
