Patent number: 7699609Abstract: A device for the treatment of periodontal disease. The device includes a handle that has a configuration familiar to dental professionals and a cartridge that is locked into the handle when use, typically delivery of a composition to a periodontal pocket, is desired. The cartridge provides for effective delivery of compositions, such as agents, as its tip is deformable, typically from a circular to an oval shape so as to flatten. The deformation may be made either manually, by the dental professional, or upon contact with teeth or other tissues, whereby this flattened tip can penetrate deeply into periodontal pockets for quick and direct application of the composition, for example, therapeutic agents.Type: GrantFiled: January 23, 2004Date of Patent: April 20, 2010Assignee: Orapharma, Inc.Inventors: James R. Lawter, Michael G. Lanzilotti, Mark Bates, Gregory H. Hunter

Patent number: 6946118Abstract: Mucositis is treated and/or prevented by administrating to a patient a formulation comprising a tetracycline that is poorly absorbed from the gastro-intestinal tract. The tetracycline may be in the form of a pharmaceutically acceptable salt or a base. The formulations may optionally also contain an antifungal agent to prevent fungal overgrowth due to reduction in the normal oral flora by the tetracycline. Such compositions have the advantage of treating the entire gastro-intestinal tract since the active ingredient is not removed from the tract via absorption. Further, such compositions minimize systemic exposure and accompanying side effects.Type: GrantFiled: September 14, 2000Date of Patent: September 20, 2005Assignee: Orapharma, Inc.Inventors: James Ronald Lawter, Stephen J.

Publication number: 20040167099Abstract: Mucositis is treated and/or prevented by administrating to a patient a formulation containing a tetracycline and at least one cationic polymer and/or mucoadhesive material. The tetracycline may be in the form of a pharmaceutically acceptable salt or a base. The formulations may optionally also contain an antifungal agent to prevent fungal overgrowth due to reduction in the normal oral flora by the tetracycline. The formulation can be formed into liquid or solid dosage forms such as mouth rinse or tablet. Such compositions have the advantage of prolonged retention of the tetracycline in the mucosa of the oral cavity.Type: ApplicationFiled: October 6, 2003Publication date: August 26, 2004Applicant: OraPharma, Inc.Inventor: James Ronald Lawter

Publication number: 20040029843Abstract: Mucositis is treated and/or prevented by administrating to a patient a rapidly disintegrating solid dosage form comprising a tetracycline. The dosage form may contain another agent such as an NSAID, an inflammatory cytokine inhibitor, a mast cell inhibitor, an MMP inhibitor, an NO inhibitor, or a mixture thereof. The dosage forms may optionally also contain an antifungal agent to prevent fungal overgrowth due to reduction in the normal oral flora by the tetracycline. The tetracycline is preferably one that is poorly absorbed from the gastrointestinal tract. Such compositions have the advantage of treating the entire gastrointestinal tract since the active ingredient is not removed from the tract via absorption. Further, such compositions minimize systemic exposure and accompanying side effects. The compositions can be formulated as solid dosage forms comprising a tetracycline which disintegrates in an aqueous medium or saliva within in a short period, for example, two minutes. .Type: ApplicationFiled: June 20, 2003Publication date: February 12, 2004Applicant: OraPharma, Inc.Inventor: James Ronald Lawter
