Gum pad for delivery of medication to mucosal tissues
First Claim
1. A gum pad for use in the mouth of a person comprising:
- (a) a nonporous first layer;
(b) a second layer adjacent said nonporous first layer having a medication capable of being liquified by saliva retained in said second layer;
(c) a semi-permeable third layer covering said second layer and sealed to said first layer to form a pocket enclosing said second layer, (d) wherein said semi-permeable third layer is permeable to saliva such that the saliva can penetrate therethrough to liquify the medication retained in said second layer and transport it by liquid diffusion back through said semi-permeable third layer; and
wherein said first layer is made of a stable and flexible material and has an outer surface adapted to be installed in place on the gum in the mouth of the person using the gum pad, with said third layer facing outwardly toward oppositely facing mucosal tissues in the mouth.

Abstract
The Gum Pad is a laminate composed of: (a) a synthetic base or backing layer which is configured to be held in place on the gingiva (gums) in the mouth; (b) an intermediate, reservoir layer for containing medication therein; and (c) a semi-permeable outer layer facing outwardly toward oral mucosal tissues in the mouth which will allow saliva to enter and dissolve the medication in the reservoir layer into solution and pass the diffused saliva-medication solution outwardly to the oral mucosal tissues. The backing layer is placed on the gum so that the semi-permeable outer layer faces outwardly toward the buccal mucosa. Saliva enters the semi-permeable layer and dissolves the medication in the reservoir layer, then diffuses outwardly through the semi-permeable layer to the mucosal tissues in the mouth where it is readily absorbed into the circulatory system. The Gum Pad can be used for the topical or systemic delivery of a wide range of pharmaceutical and nutritional agents, for the treatment of a variety of human disorders and diseases.

10. A medication delivery method of delivering medication into the human circulatory system from within the mouth of a person, said method comprising the steps of:
-
(a) providing a pad having a nonporous first layer, a second layer for retaining a medication therein, and a semi-permeable third layer covering the second layer and sealed to said first layer so as to form a sealed pocket enclosing said second layer;
(b) impregnating said second layer with medication to be delivered into the human circulatory system; and
(c) placing said pad on a supporting part within the mouth of the person with said semi-permeable third layer facing outwardly toward mucosal tissue in the mouth so as to permit saliva within the mouth to Penetrate into said semi-permeable third layer and liquify the medication in said second layer and transport it by diffusion through said semi-permeable third layer for absorption into the mucosal tissue, wherein the medication retained in said second layer is selected from the group consisting of;
anticonvulsants;
anxiolytics;
anesthetics;
analgesics;
peptides;
antiemetics; and
beta-adrenergic blockers.- View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of treating human systemic disease or disorder by delivery of medication into the human circulatory system through mucosal tissue within the mouth of a person, comprising the steps of:
-
(a) providing a pad having a medication soluble by saliva retained therein with a semi-permeable outer layer covering the medication retained in the pad, said semi-permeable outer layer facing outwardly toward mucosal tissue within the mouth of the person;
(b) placing said pad on a supporting part within the mouth of the person with said semi-permeable third layer facing outwardly toward mucosal tissue in the mouth so as to permit saliva within the mouth to penetrate into said semi-permeable third layer and liquify the medication in said second layer; and
(c) permitting saliva within the mouth to penetrate into the pad through said semi-permeable outer layer to liquify the medication retained therein; and
(d) transporting the medication dissolved in the saliva by diffusion through said semi-permeable outer layer for absorption into the mucosal tissue within the mouth of the person where it can enter into the human circulatory system. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
