A big request is to actively add their feedback on the drug: the medicine helped or did not help get rid of the disease, which were observed complications and side effects, possibly not declared by the manufacturer in the annotation. Analogues of Glucophage in the presence of existing structural analogues. Use for the treatment of type 2 diabetes in adults, children, as well as during pregnancy and lactation. Composition and interaction of the drug with alcohol.
Glucophage - oral hypoglycemic agent from the biguanide group.
Glucophage reduces hyperglycemia, without leading to the development of hypoglycemia. Unlike derivatives of sulfonylurea, it does not stimulate insulin secretion and does not have hypoglycemic action in healthy individuals.
Increases the sensitivity of peripheral receptors to insulin and the utilization of glucose by cells. Reduces the production of glucose by the liver by inhibiting gluconeogenesis and glycogenolysis. Delays the absorption of glucose in the intestine.
Metformin (the active substance of the drug Glucophage) stimulates the synthesis of glycogen, affecting glycogen synthetase. Increases the transport capacity of all types of membrane glucose transporters.
In addition, it has a beneficial effect on lipid metabolism: it reduces the content of total cholesterol, LDL and TG.
Against the background of taking Glucophage the body weight of the patient either remains stable or moderately decreases.
Composition
Metformin hydrochloride + excipients.
Pharmacokinetics
After taking the drug inside Glukofazh is completely absorbed from the digestive tract. With simultaneous intake of food, absorption of Metformin is reduced and delayed. Absolute bioavailability is 50-60%.Metformin is quickly distributed into the tissues of the body. Virtually does not bind to plasma proteins. To a very small extent, it is metabolized and excreted by the kidneys.
Indications
Diabetes mellitus type 2, especially in patients with obesity, with ineffectiveness of diet and exercise:
- in adults as a monotherapy or in combination with other oral hypoglycemic drugs, or with insulin;
- in children aged 10 years and older as a monotherapy or in combination.
Forms of release
Tablets coated with 500 mg, 850 mg and 1000 mg.
Long-acting tablets 500 mg and 750 mg (Long).
Instructions for use and reception scheme
The drug is taken orally.
Pills
Adults
Monotherapy and combination therapy with other oral hypoglycemic agents
The usual initial dose is 500 mg or 850 mg 2-3 times a day after or during meals. A further gradual increase in the dose is possible depending on the concentration of glucose in the blood.
The maintenance dose of the drug is usually 1500-2000 mg per day. To reduce side effects from the gastrointestinal tract, the daily dose should be divided into 2-3 doses.The maximum dose is 3000 mg per day, divided into 3 doses.
A slow increase in dosage can help improve gastrointestinal tolerance.
Patients receiving metformin at doses of 2-3 g per day can be transferred to receive Glucophage 1000 mg. The maximum recommended dose is 3000 mg per day, divided into 3 doses.
In case of planning the transition from taking another hypoglycemic drug: it is necessary to stop taking another drug and start taking Glucophage in the dose indicated above.
Combination with insulin
To achieve better control of glucose in the blood, metformin and insulin can be used as a combination therapy. The usual initial dose of Glucophage is 500 mg or 850 mg 2-3 times a day, while the insulin dose is selected based on the concentration of glucose in the blood.
Children and teens
In children aged 10 years and older, Glucophage can be used both as monotherapy and in combination with insulin. The usual initial dose is 500 mg or 850 mg once a day after or during a meal. After 10-15 days, the dose should be adjusted based on the blood glucose concentration.The maximum daily dose is 2000 mg, divided into 2-3 doses.
Elderly patients
Because of a possible reduction in renal function, the dose of metformin should be selected under regular monitoring of renal function (determine the creatinine content in serum at least 2-4 times per year).
Glucophage should be taken daily, without interruption. In the event of discontinuation of treatment, the patient should inform the physician about this.
Long tablets
The drug is taken orally. Tablets are swallowed whole, not liquid, squeezed with a small amount of water.
Long-acting tablets 500 mg
The drug is taken during dinner (1 time per day) or during breakfast and dinner (2 times a day). Tablets should be taken only during meals.
The dose of the drug is determined based on the glucose content in the blood plasma.
Monotherapy and combination therapy in combination with other hypoglycemic agents
The drug Glucophage Long is prescribed in an initial dose of 500 mg (1 tablet) 1 time per day during dinner.
When switching from Glucophage (tablets with the usual release of the active substance), the initial dose of Glucophage Long should be equal to the daily dose of Glucophage.
Dose titration: depending on the glucose level in the blood plasma, every 10-15 days the dose is slowly increased by 500 mg to the maximum daily dose.
The maximum daily dose of Glucophage Long is 2 g (4 tablets) once a day during dinner.
If glucose control is not achieved at the maximum daily dose taken once a day, then you can consider the possibility of dividing this dose into several doses per day as follows: 2 tablets at breakfast time and 2 tablets at dinner time.
When Glucophage Long is used together with insulin, the usual initial dose of the drug is 500 mg (1 tablet) once a day, and the insulin dose is selected based on the results of measuring the glucose content in the blood plasma.
Glucophage Long should be taken daily, without interruption. In the event of discontinuation of treatment, the patient should inform the physician about this.
If the next dose is missed, the next dose should be taken at the usual time. You can not double the dose of the drug.
Long-acting tablets 750 mg
The drug is taken during or after dinner (1 time per day).
Monotherapy and combination therapy in combination with other hypoglycemic agents
The initial dose is, as a rule, 1 tablet 1 time per day.
After 10-15 days of treatment, the dose should be adjusted based on the results of measuring blood glucose. Slow increase in dose helps reduce side effects from the digestive tract.
The recommended dose of the drug is 1.5 g (2 tablets) once a day. If the recommended dose does not manage to achieve adequate control of glycemia, it is possible to increase the dose to a maximum of 2.25 g (3 tablets) once a day.
If adequate glycemic control is not achieved when taking 3 tablets 750 mg once a day, then it is possible to switch to a metformin preparation with the usual release of the active substance with a maximum daily dose of 3 g.
For patients already receiving metformin tablets, the initial dose of Glucophage Long should be equivalent to the daily dose of tablets with normal release. Patients taking metformin in the form of tablets with a normal release in a dose exceeding 2 g do not recommend switching to Glucophage Long.
In case of planning a transition from another hypoglycemic agent: it is necessary to stop taking another drug and start taking Glucophage Long in the dose indicated above.
Combination with insulin
To achieve better control of blood glucose concentrations, metformin and insulin can be used as a combination therapy. The usual initial dose of Glucophage Long is 1 750 mg tablet once a day during supper, while the insulin dose is selected based on the results of measuring the glucose level in the blood.
Special patient groups
In elderly patients and patients with reduced renal function, the dose is adjusted based on the evaluation of renal function, which must be performed regularly at least 2 times per year.
The drug Glucophage Long should not be used in children and adolescents under 18 years due to lack of application data.

Application in pregnancy and lactation
The drug is contraindicated for use in pregnancy.
Decompensated diabetes mellitus during pregnancy is associated with an increased risk of congenital malformations and perinatal mortality.A limited amount of evidence suggests that the use of metformin in pregnant women does not increase the risk of congenital malformations in children.
When planning pregnancy, and also in case of pregnancy on the background of taking metformin, the drug should be canceled, and insulin therapy is prescribed. It is necessary to maintain the level of glucose in the blood plasma at the level closest to the norm in order to reduce the risk of fetal malformations.
Metformin is excreted in breast milk. Side effects in newborns with breastfeeding against metformin were not observed. However, due to the limited amount of data, the use of the drug in breastfeeding is not recommended. The decision to stop breastfeeding should be taken in consideration of the benefits of breastfeeding and the potential risk of side effects in the child.
Use in children
The diagnosis of Type 2 diabetes mellitus should be confirmed before the start of treatment with metformin.
In clinical studies lasting 1 year, it was shown that metformin does not affect growth and puberty.However, in view of the lack of long-term data, careful monitoring of the subsequent influence of metformin on these parameters in children, especially during puberty, is recommended. The most careful control is needed for children aged 10-12 years.
Published data, postmarketing data, as well as data from controlled clinical trials in a limited pediatric population in the 10 to 16 age group, show that the side effects in children are similar in nature and severity to those in adult patients.
special instructions
Lactacidosis
Lactacidosis is a rare but severe (high mortality in the absence of emergency treatment) complication that may occur due to the cumulation of metformin. Cases of lactic acidosis with metformin were mainly in diabetic patients with severe renal failure.
Other associated risk factors, such as decompensated diabetes mellitus, ketosis, prolonged fasting, alcoholism, liver failure and any condition associated with severe hypoxia, should be considered. This can help reduce the incidence of lactic acidosis.
The risk of developing lactic acidosis when nonspecific signs appear, such as muscle cramps, accompanied by dyspeptic symptoms, abdominal pain and severe asthenia, should be considered. Lactacidosis is characterized by acidotic dyspnea, abdominal pain and hypothermia followed by coma.
Diagnostic laboratory indicators are a decrease in blood pH (less than 7.25), a lactate content in the blood plasma above 5 mmol / l, an increased anion gap and a lactate / pyruvate ratio. If you suspect a metabolic acidosis, stop taking the medication and consult a doctor immediately.
Surgical operations
The use of Glucophage should be discontinued 48 hours before planned surgical operations and can be continued no earlier than 48 hours after, provided that during the examination the renal function was found to be normal.
Kidney function
Since metformin is excreted by the kidneys, before starting treatment and regularly thereafter, it is necessary to determine QC: 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 CC at the lower border of norm.
Special caution should be exercised in cases of possible impairment of kidney function in elderly patients, with the simultaneous use of antihypertensive drugs, diuretics or NSAIDs.
Other Precautions
Patients are encouraged to continue to follow a diet with an even intake of carbohydrates throughout the day. Patients with excessive body weight are recommended to continue to observe a hypocaloric diet (but not less than 1000 kcal per day).
It is recommended that regular laboratory tests be performed on a regular basis to control diabetes mellitus.
Metformin with monotherapy does not cause hypoglycemia, but it is recommended to use caution when used in combination with insulin or other hypoglycemic agents (including sulfonylurea derivatives, repaglinide).
Impact on the ability to drive vehicles and manage mechanisms
Monotherapy with Glucophage does not cause hypoglycemia, so it does not affect the ability to drive vehicles and mechanisms. Nevertheless, patients should be cautioned about the risk of hypoglycemia when using metformin in combination with other hypoglycemic drugs (including those with sulfonylureas, insulin, repaglinide).
Drug Interactions
Contraindicated combinations
Iodine-containing radiopaque means: on the background of functional renal failure in diabetic patients, a radiological study using iodine-containing radiocontrast agents can cause the development of lactic acidosis. Treatment with Glucophage should be canceled depending on the function of the kidneys 48 hours before or at the time of radiologic examination using iodine-containing radiopaque means and do not resume earlier 48 hours after, provided that during the examination the renal function was found to be normal.
Unrecommended combinations
Alcohol: with acute alcohol intoxication, the risk of developing lactic acidosis increases, especially in the case of:
- malnutrition, low-calorie diet;
- hepatic insufficiency.
During taking the drug, you should avoid drinking alcohol and drugs containing ethanol.
Combinations that require caution
It is not recommended simultaneous reception of danazol in order to avoid hyperglycemic action of the latter.If necessary, treatment with danazol and after discontinuation of the latter requires a correction of the dose of Glucophage drug under the control of the concentration of glucose in the blood.
Chlorpromazine when taken in high doses (100 mg per day) increases the concentration of glucose in the blood, reducing the release of insulin. When treating with neuroleptics and after stopping the intake of the latter, correction of the dose of the drug under the control of the concentration of glucose in the blood is required.
Glucocorticosteroids (GCS) for systemic and topical administration reduce glucose tolerance, increase the concentration of glucose in the blood, sometimes causing ketosis. In the treatment of GCS and after discontinuation of the latter, correction of the dose of Glucophage is required under the control of the glucose concentration in the blood.
Simultaneous reception of "loop" diuretics can lead to the development of lactic acidosis due to possible functional renal failure. Do not prescribe Glucophage if the SC is less than 60 ml / min.
Beta2-adrenomimetics in the form of injections increase the concentration of glucose in the blood due to stimulation of beta2-adrenoreceptors. In this case, it is necessary to monitor the concentration of glucose in the blood.If necessary, it is recommended to prescribe insulin.
With the simultaneous use of the above medicines, more frequent monitoring of the glucose level in the blood may be required, especially at the beginning of the treatment. If necessary, the dose of metformin can be adjusted during treatment and after its termination.
ACE inhibitors and other antihypertensive drugs can reduce the concentration of glucose in the blood. If necessary, the dose of metformin should be adjusted.
With the simultaneous use of the drug Glucophage with derivatives of sulfonylurea, insulin, acarbose, salicylates may develop hypoglycemia.
Nifedipine increases the absorption of metformin.
