Biguanide And Sulfonylurea Formulations For The Prevention And Treatment Of Insulin Resistance And Type 2 Diabetes Mellitus

US Patent:
6693094, Feb 17, 2004
Filed:
Mar 7, 2002
Appl. No.:
10/093476
Inventors:
Don C. Pearson - Lakewood WA
Kenneth T. Richardson - Anchorage AK
Assignee:
Chrono RX LLC - Anchorage AK
International Classification:
A61K 31555
US Classification:
514188, 51425506, 514456, 514458, 514494, 514505, 514565, 514593, 514635
Abstract:
The invention describes formulations that include either metformin, sulfonylurea or a biguanide-sulfonylurea combination as one active ingredient in addition to specific, other active ingredients. The compositions and dosage forms of the invention are clinically useful as methods for increasing the effectiveness, efficiency and safety of the included biguanide (metformin) and/or sulfonylurea in the prevention and treatment of insulin resistance and diabetes mellitus. The carefully chosen additional active ingredients of the invention are designed in a modular fashion to prevent and rectify adverse events associated with insulin resistance syndrome and diabetes mellitus, and those adverse incidences associated with the concurrent use of metformin and/or the sulfonylureas. When clinically administered, the invention will provide therapeutic levels of metformin and of a sulfonylurea, alone or in combination, and broaden their usefulness. The invention will retard the progression of insulin resistance to type 2 diabetes, and reduce the serious microvascular and macrovascular complications commonly associated with insulin resistance syndrome and diabetes mellitus.

Dosage Forms Useful For Modifying Conditions And Functions Associated With Hearing Loss And/Or Tinnitus

US Patent:
6524619, Feb 25, 2003
Filed:
Jan 19, 2001
Appl. No.:
09/765974
Inventors:
Don C. Pearson - Lakewood WA
Kenneth T. Richardson - Anchorage AK
Assignee:
Chronorx, Inc. - Anchorage AK
International Classification:
A61K 920
US Classification:
424472, 424464, 424468
Abstract:
The invention defines interdependent biofactors and biomolecules, and clinically useful formulations that are comprised of them. The active agents are demonstrated to be complementary in their physiologic functions especially as these relate to the quenching of free radicals and to the support of endothelial physiology, the reduction of hyperinsulinemia and improvements in vascular health. The active components of the invention are selected for inclusion in precise combinations specifically because they improve these various conditions and physiological functions, and by so doing reduce a variety of risks associated with hearing loss and tinnitus. The resulting enhancement of general systemic vascular health, improvement in local VIII nerve vascular health, modulation of conditions surrounding blood fluid dynamics, the consequences of hyperinsulinemia, and improvements in free radical defenses, all reduce the potential for cochlear hair cell death and VIII nerve atrophy, and the hearing loss and possible deafness that accompany them.

Formulations For The Treatment Of Insulin Resistance And Type 2 Diabetes Mellitus

US Patent:
6689385, Feb 10, 2004
Filed:
Nov 2, 2001
Appl. No.:
10/033730
Inventors:
Kenneth T. Richardson - Anchorage AK
Don C. Pearson - Lakewood WA
Assignee:
Chronorx LLC - Anchorage AK
International Classification:
A61K 920
US Classification:
424464, 451472, 451482, 451486, 451489
Abstract:
The compositions and dosage forms of the invention are clinically useful as methods for increasing the effectiveness, efficiency and safety of biguanides (metformin) and/or sulfonylureas in the prevention and treatment of insulin resistance and diabetes mellitus, alone or in combination, as a nutrient for humans. The carefully chosen active ingredients of the invention are designed in a modular fashion to prevent and rectify adverse events associated with insulin resistance syndrome and diabetes mellitus, and with the clinical use of biguanides (metformin) and/or the sulfonylureas. These modules are: (1) Mitochondrial Metabolic Group, (2) Plasma and Mitochondrial Membrane Integrity Group, (3) Nocturnal Group and, (4) Insulin Alternative Group. When used in concert with a biguanide, a sulfonylurea or with a combination of both, the invention will broaden the clinical usefulness of these drugs. The invention will retard the progression of insulin resistance to type 2 diabetes, and reduce the serious microvascular and macrovascular complications commonly associated with insulin resistance syndrome and diabetes mellitus.

Unit Dosage Forms For The Treatment Of Herpes Simplex

US Patent:
6455061, Sep 24, 2002
Filed:
Apr 5, 2001
Appl. No.:
09/828323
Inventors:
Kenneth T. Richardson - Anchorage AK
Don C. Pearson - Lakewood WA
Assignee:
ChronoRX, LLC - Anchorage AK
International Classification:
A61F 1300
US Classification:
424422, 424427, 424428, 514547, 514574
Abstract:
The components of this invention are chosen because of their complementarity for the prevention or treatment of diseases caused by the herpes simplex virus. L-Lysine favorably increases the physiologic immunomodulation necessary for defense against this virus. Zinc improves and maintains a normal immune response. 2-Deoxy-2-D-glucose and heparin sodium alter the surface interaction between the herpes virus and the cell, preventing fusion and infectivity. N-Acetyl-L-cysteine increases glutathione levels thereby creating a thiol redox barrier to the virus at the cell membrane. Quercetin reduces intracellular replication of the herpes virus and viral infectivity. Ascorbate, in concert with copper and D--tocopherol, provides an antioxidant defense against the herpes virus, which tends to lose latency during period of oxidative, free radical excess. Selenium and quercetin also participate in reducing various oxidative stresses. Together the components of this invention provide the potential for improved resistance to, improved recovery from, and a decreased frequency of recurrence of herpes simplex virus infection.

Dosage Forms For The Treatment Of The Chronic Glaucomas

US Patent:
6207190, Mar 27, 2001
Filed:
Aug 11, 1999
Appl. No.:
9/372362
Inventors:
Kenneth T. Richardson - Anchorage AK
Don C. Pearson - Lakewood WA
Assignee:
ChronoRX, LLC - Anchorage AK
International Classification:
A61K9/24;9/22
US Classification:
424472
Abstract:
Four interdependent functional groups of biofactors and biomolecules are identified and formulations are defined which are comprised of their members. The active agents are demonstrated to be complementary in their physiological functions especially as these relate to endothelial biochemistry and physiology, hyperinsulinemia and, ultimately, to vascular health. The active components of the invention are selected for inclusion in precise combinations that reduce a variety of risks of vasculopathy in addition to reducing intraocular pressure. Widespread systemic improvement associated with local, optic nerve betterment of vascular health, reduces the risk of optic nerve atrophy with its accompanying visual field loss and potential blindness. The reduction of this maximizes the potential clinical therapeutic success of current medical, IOP-lowering, anti-glaucoma mediations.
