Description

Pharmacological action

Pharmacotherapeutic group: Hypoglycemic agent for oral administration (second-generation sulfonylurea derivative + biguanide)

ATX:

A.10.BD02 Metformin and sulfonamides

Pharmacodynamics A fixed combination of two oral hypoglycemic agents of various pharmacological groups: glibenclamide and metformin.

Metformin belongs to the group of biguanides and reduces the concentration of both basal and postprandial glucose in blood plasma. Metformin does not stimulate insulin secretion, and therefore does not cause hypoglycemia. It has 3 mechanisms of action: it reduces the production of glucose by the liver by inhibiting gluconeogenesis and glycogenolysis increases the sensitivity of peripheral insulin receptors, the consumption and utilization of glucose by cells in the muscles delays the absorption of glucose in the gastrointestinal tract (GIT). The drug also has a beneficial effect on the lipid composition of the blood, reducing the concentration of total cholesterol, low density lipoproteins (LDL) and triglycerides.

Glibenclamide belongs to the group of sulfonylurea derivatives of the second generation. The glucose concentration when taking glibenclamide decreases as a result of stimulation of insulin secretion by beta cells of the pancreas.

Metformin and glibenclamide have different mechanisms of action, but mutually complement each other’s hypoglycemic activity. The combination of two hypoglycemic agents has a synergistic effect in lowering glucose concentrations.

Pharmacokinetics: Glibenclamide

Absorption of

When taken orally, absorption from the gastrointestinal tract is more than 95%. The time to reach maximum concentration is 4 hours, the volume of distribution is about 10 liters.

Distribution of

Communication with blood plasma proteins is high (99%).

Metabolism and excretion

Almost completely metabolized in the liver to form two inactive metabolites, which are excreted by the kidneys (40%) and through the intestines (60%). The elimination half-life is from 4 to 11 hours.

Metformin

Absorption of

After oral administration, it is absorbed from the gastrointestinal tract completely enough, the maximum plasma concentration is reached within 2.5 hours. Absolute bioavailability is from 50 to 60%.

Distribution

Metformin is rapidly distributed in tissues and practically does not bind to plasma proteins.

Metabolism and excretion

Metabolized to a very low degree and excreted by the kidneys. About 20-30% of metformin is excreted through the intestine unchanged. The elimination half-life is an average of 6.5 hours.

Pharmacokinetics in special patient groups

In case of impaired renal function, the renal clearance of metformin decreases, as does the clearance of creatinine, while the half-life increases, which leads to an increase in the concentration of metformin in blood plasma.

The combination of metformin and glibenclamide in one tablet has the same bioavailability as when taking tablets containing metformin or glibenclamide in isolation. The bioavailability of metformin in combination with glibenclamide is not affected by food intake, as well as the bioavailability of glibenclamide, however, the rate of absorption of glibenclamide increases with food intake.

Indications

Type 2 diabetes in adults:

with the ineffectiveness of diet therapy, exercise and previous monotherapy with metformin or sulfonylurea derivatives

to replace the previous therapy with two drugs (metformin and sulfonylurea derivative) in patients with stable and adequate glycemic control.

Contraindications

Hypersensitivity to metformin, glibenclamide or other sulfonylurea derivatives, as well as to other excipients of the drug, type 1 diabetes mellitus, diabetic ketoacidosis, diabetic precoma, diabetic coma renal failure or impaired renal function (creatinine clearance less than 60 ml / min) acute conditions that can lead to a change in renal function: dehydration, severe infection, shock, intravascular administration of iodine-containing contrast agents (see Special instructions) acute or chronic diseases that are accompanied by tissue hypoxia: heart or respiratory failure, recent myocardial infarction, liver porphyria failure, pregnancy, breastfeeding neous reception miconazole major surgery, trauma, extensive burns and other conditions requiring insulin therapy chronic alcoholism, acute alcohol intoxication lactic acidosis (including history) adherence to a low-calorie diet (less than 1000 kcal / day) children under 18 years of age.

It is not recommended to use the drug in people over 60 years old who perform heavy physical work, which is associated with an increased risk of developing lactic acidosis in them.

Caution: Fever syndrome, adrenal insufficiency, hypofunction of the anterior pituitary of the thyroid gland disease (with uncompensated impairment of its function) in the elderly due to the risk of hypoglycemia.

Use during pregnancy and lactation

During pregnancy, the use of a combination of glibenclamide and metformin is contraindicated. The patient should be warned that that during the treatment with Glibenfage, it is necessary to inform the doctor about the planned pregnancy and the onset of pregnancy. When planning pregnancy, as well as in the case of pregnancy during the period of taking the drug, it should be canceled and insulin therapy should be prescribed.

The combination of glibenclamide and metformin is contraindicated in breastfeeding, as there is no evidence of its ability to pass into breast milk. If it is necessary to use the drug during breastfeeding, you should switch to insulin therapy or stop breastfeeding.

Special instructions

Treatment with Glibenfage onlyunder the supervision of a doctor! When taking the drug, it is necessary to strictly follow the doctor’s recommendations on dieting and self-monitoring of glucose concentration in the blood. It is necessary to regularly monitor the concentration of glucose in the blood on an empty stomach and after eating.

Lactic acidosis

Lactic acidosis is an extremely rare, but serious (high mortality rate in the absence of emergency treatment) complication that may occur due to cumulation of metformin. Cases of lactic acidosis with the use of metformin occurred mainly in patients with diabetes mellitus and severe renal failure. Other associated risk factors should be considered, such as poorly controlled diabetes mellitus, ketosis, prolonged fasting, excessive alcohol consumption, liver failure, and any condition associated with severe hypoxia.

The risk of lactic acidosis should be considered when nonspecific symptoms such as muscle cramps accompanied by dyspeptic disorders, abdominal pain and severe malaise appear. In severe cases, acidotic shortness of breath, hypoxia, hypothermia, and coma may occur.

Diagnostic laboratory parameters are: low blood pH, plasma lactate concentration above 5 mmol / l, increased anionic interval and lactate / pyruvate ratio.

Hypoglycemia

Since the drug Glibenfage contains glibenclamide, taking the drug is associated with a risk of hypoglycemia in the patient. Gradual titration of the dose after the start of treatment can prevent the occurrence of hypoglycemia. This treatment can only be prescribed to the patient, adhering to a regular meal regimen (including breakfast). It is important that carbohydrate intake is regular, as the risk of developing hypoglycemia increases with a late meal, inadequate or unbalanced carbohydrate intake.

The development of hypoglycemia is most likely with a hypocaloric diet, after intense or prolonged physical activity, with alcoholic beverages, or with a combination of hypoglycemic agents. Due to compensatory reactions caused by hypoglycemia, increased sweating, a sense of fear, tachycardia, increased blood pressure, a feeling of palpitations, angina pectoris and arrhythmia can occur. The last symptoms may be absent if hypoglycemia develops slowly, in case of autonomic neuropathy or while taking beta-blockers, clonidine, reserpine, guanethidine, or sympathomimetics.

Other symptoms of hypoglycemia in patients with diabetes can include headache, hunger, nausea, vomiting, severe fatigue, sleep disorders, excited state, aggression, impaired concentration and psychomotor reactions, depression, confusion, speech impairment, visual impairment, trembling, paralysis and paresthesia, dizziness, delirium, cramps, doubt, unconsciousness, shallow breathing and bradycardia.

Cautious use of the drug, dosage selection and proper instructions for the patient are important to reduce the risk of hypoglycemia. If the patient recurs attacks of hypoglycemia, which are either severe or associated with ignorance of the symptoms, consideration should be given to treatment with other hypoglycemic agents. Factors contributing to the development of hypoglycemia: the simultaneous use of alcoholic beverages, especially during fasting, refusal or (especially for elderly patients) the patient ² „¢s inability to interact with the doctor and follow the recommendations in the instructions for use poor nutrition, irregular meals, fasting or changes in diet, imbalance between physical activity and carbohydrate intake: renal failure, severe liver failure, overdose of the drug Glibenfage individual endocrine disrupted ia: insufficiency of the thyroid gland, pituitary gland and adrenal glands at the same time taking certain medications.

Renal and Hepatic Insufficiency

Pharmacokinetics and / or pharmacodynamics may vary in patients with hepatic impairment or severe renal impairment. The hypoglycemia that occurs in such patients can be prolonged, in which case appropriate treatment should be started.

Instability of blood glucose

In case of surgical intervention or other cause of decompensation of diabetes mellitus, it is recommended to provide a temporary transition to insulin therapy. Symptoms of hyperglycemia are frequent urination, severe thirst, dry skin. 48 hours before the planned surgical intervention or intravenous administration of an iodine-containing radiopaque agent, the administration of the drug Glibenfage should be discontinued. Treatment is recommended to be resumed after 48 hours, and only after renal function has been evaluated and recognized as normal.

Kidney Function

Since metformin is excreted by the kidneys, before starting treatment and regularly thereafter, it is necessary to determine the creatinine clearance and / or serum creatinine concentration: at least once a year in patients with normal renal function, and 2-4 times a year in elderly patients, as well as in patients with creatinine clearance at the upper limit of normal.

It is recommended to be especially careful in cases where kidney function may be impaired, for example, in elderly patients, or in the case of initiation of antihypertensive therapy, diuretics or non-steroidal anti-inflammatory drugs (NSAIDs).

Other Precautions

The patient should inform the doctor if infectious diseases of the lower respiratory tract, genitals, kidneys, and urinary tract develop.

Impact on the ability to drive transp. Wed and fur .: Patients should be informed about the risk of hypoglycemia and should observe precautions when driving a vehicle and working with mechanisms that require an increased concentration of attention and speed of psychomotor reactions.

Side effects of

The following adverse reactions may occur during treatment with Glibenfage.

WHO classification of the incidence of adverse reactions: very often -? 1/10 appointments, often from? 1/100 to <1/10 appointments, infrequently - from? 1/1000 to <1/100 appointments, rarely - from? 1 / 10,000 to <1/1000 appointments, very rarely - <1/10000 appointments. Classification of unwanted adverse reactions according to damage to organs and organ systems (medical dictionary for regulatory activity Med-DRA). Disorders from the blood and lymphatic system: These adverse events disappear after discontinuation of the drug. Rarely: leukopenia and thrombocytopenia. Very rare: agranulocytosis, hemolytic anemia, bone marrow aplasia, and pancytopenia. Disorders of the immune system: Very rare: anaphylactic shock. Cross-hypersensitivity reactions to sulfonamides and their derivatives may occur. Metabolic and nutritional disorders: Hypoglycemia (See Overdose, Special Instructions). Rarely: attacks of porphyria (hepatic or cutaneous). Very rare: lactic acidosis (See Special Instructions). Decreased absorption of vitamin B12, accompanied by a decrease in its concentration in serum with prolonged use of metformin. If megaloblastic anemia is detected, the possibility of such an etiology must be considered. Disulfiram-like reaction with ethanol. Disorders of the nervous system: Often: taste disturbance (metallic taste in the mouth). Disorders of the organ of vision: At the beginning of treatment, a temporary visual impairment may occur due to a decrease in the concentration of glucose in the blood. Disorders of the gastrointestinal tract: Very often: nausea, vomiting, diarrhea, abdominal pain and lack of appetite. These symptoms are more common at the beginning of treatment and in most cases pass on their own. To prevent the development of these symptoms, it is recommended to take the drug in 2 or 3 doses, a slow increase in the dose of the drug also improves its tolerance. Disorders from the liver and biliary tract: Very rarely: impaired liver function or hepatitis requiring discontinuation of treatment. Disorders of the skin and subcutaneous tissue: Rarely: skin reactions, such as: itching, urticaria, maculopapular rash. Very rare: photosensitivity, skin or visceral allergic vasculitis, polymorphic erythema, exfoliative dermatitis. Laboratory and instrumental data: Infrequently: moderate increase in serum urea and creatinine concentrations. Very rare: hyponatremia. Overdose of In case of an overdose, hypoglycemia may occur due to the presence of the sulfonylurea derivative in the preparation (see Special instructions). Symptoms of mild to moderate hypoglycemia without loss of consciousness and neurological symptoms can be stopped by the immediate intake of easily digestible carbohydrates. Need to adjust the dose of the drug and / or change in diet. The occurrence of severe hypoglycemic reactions in patients with diabetes, accompanied by coma, convulsions or other neurological disorders, requires emergency medical care. Intravenous administration of a dextrose solution is necessary immediately after diagnosis or suspicion of hypoglycemia occurs, before the patient is hospitalized. After regaining consciousness, it is necessary to take food rich in easily digestible carbohydrates (in order to avoid the re-development of hypoglycemia). Plasma glibenclamide clearance may increase in patients with liver disease. Since glibenclamide is actively associated with blood proteins, the drug is not excreted during dialysis. An overdose or the presence of conjugated risk factors can provoke the development of lactic acidosis, as metformin is part of the drug (see. Special instructions). Lactic acidosis is a condition requiring emergency medical care treatment of lactic acidosis should be carried out in a hospital. The most effective treatment option to remove lactate and metformin is hemodialysis. Storage conditions In the original packaging of the manufacturer at a temperature not exceeding 25 ° C. Keep out of the reach of children. The Expiration of is 3 years. Deystvuyuschee Hlybenklamyd substances, Metformin Dosage form tablet
