Description
Technical field
The present invention relates to medical art, be specifically related to a kind of diabetes combination of oral medication.
Background technology
The metabolic disease of diabetes to be one group with hyperglycemia be feature.Hyperglycemia be then due to defect of insulin secretion or its biological agent impaired, or both have concurrently and cause.Long-standing hyperglycemia during diabetes, causes various tissue, particularly eye, kidney, heart, blood vessel, neural chronic lesion, dysfunction.
The generally acknowledged form of usual existence two kinds of diabetes.In type 1 diabetes or insulin-dependent diabetes (IDDM), patient produces seldom or does not have insulin, regulates the hormone of glucose application.In type 2 diabetes mellitus or noninsulindependent diabetes (NIDDM), still produce insulin in the body.There is in the stimulation glucose of the patient suffering from type 2 diabetes mellitus in main insulin-sensitive tissue (it is muscle, liver and fatty tissue) and lipid metabolism the toleration to insulin action.These patients have the insulin of common level usually, and may have hyperinsulinemia (plasma insulin level of rising), because they compensate by the insulin of secretion rise the insulin effects reduced.Insulin resistance can not be caused by the Insulin receptor INSR reducing quantity but be caused by the rear Insulin receptor INSR binding deficient understood not yet completely substantially.This lacks and to cause in the oxidation of glucose in the activation of the insulin-mediated of inadequate picked-up, muscle and storage and fatty tissue glucose in lipidolysis and liver to produce to the responding ability of insulin and the suppression of insufficient insulin-mediated of secretion.
Current Remedies for diabetes is maintaining treatment effect, many employing 100mg active matter oral doses, and needs daily repeatedly to take.Due to the side effect of active matter, other health hazards are caused to patient, meanwhile, due to the increase of dosage, also make medicine cost increase, cause the raising for the treatment of cost.
Summary of the invention
The object of the invention is to propose a kind of diabetes combination of oral medication, its composite by two kinds of dissimilar active matters, under the prerequisite reaching identical therapeutic effect, the use amount of the active matter of medicine is reduced at least 1/2.
For reaching this object, the present invention by the following technical solutions:
A kind of diabetes combination of oral medication, it comprises following component:
(1) 5-(3-hydroxyl-7-propoxyl group naphthalene-2-base)-1,1-dioxo-[1,2,5] thiadiazolidine-3-ketone potassium salt of 10-20mg
(2) 3-(2-(2', 6'-dimethyl-[1,1'-biphenyl]-3-base)-4, the 4-bis-fluoro chromane-6-base) propanoic acid of 20-30mg
(3) 200-300mg microcrystalline Cellulose,
(4) 10-25mg cross-linking sodium carboxymethyl cellulose, and
(5) 1-8mg magnesium stearate.
Described 5-(3-hydroxyl-7-propoxyl group naphthalene-2-base)-1,1-dioxo-[1,2,5] thiadiazolidine-3-ketone potassium salt and 3-(2-(2', 6'-dimethyl-[1,1'-biphenyl]-3-base)-4,4-bis-fluoro chromane-6-bases) ratio of propanoic acid is less than 1.
