Publication number: 20090098203Abstract: 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: May 16, 2008Publication date: April 16, 2009Inventor: James Ronald Lawter

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. Comiskey

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

Patent number: 5942253Abstract: Formulations for controlled, prolonged release of GM-CSF have been developed. These are based on solid microparticles formed of the combination of biodegradable, synthetic polymers such as poly(lactic acid) (PLA), poly(glycolic acid) (PGA), and copolymers thereof with excipients and drug loadings that yield zero order or first order release, or multiphasic release over a period of approximately three to twenty one days, preferably one week, when administered by injection. In the preferred embodiment, the microparticles are microspheres having diameters in the range of 10 to 60 microns, formed of a blend of PLGA having different molecular weights, most preferably 6,000, 30,000 and 41,000. Other embodiments have been developed to alter the release kinetics or the manner in which the drug is distributed in vivo.Type: GrantFiled: October 12, 1995Date of Patent: August 24, 1999Assignees: Immunex Corporation, American Cyanamid CompanyInventors: Wayne Gombotz, Dean Pettit, Susan Pankey, James Ronald Lawter, W.
