Metformin 1000 mg is a fundamental pharmacological intervention designed to manage and regulate blood glucose levels in patients with Type 2 Diabetes Mellitus. Classified as a biguanide antidiabetic preparation, it is particularly effective for patients with excess body weight where lifestyle modifications, such as specialized diets and exercise, have not achieved glycemic targets. By targeting metabolic pathways without stimulating additional insulin secretion, Metformin 850 mg serves as a primary tool for reducing long-term diabetic complications and maintaining metabolic stability in both adults and adolescents.
Each film-coated tablet is formulated to provide consistent therapeutic release:
Active Substance: Metformin hydrochloride (as 100% substance) — 1000 mg.
Auxiliary Substances: Sodium starch glycolate (type A), povidone, corn starch, magnesium stearate, and colloidal anhydrous silicon dioxide.
Film Coating: Hypromellose, polyethylene glycol 6000, talc, titanium dioxide (E171), and propylene glycol.
Metformin hydrochloride exerts its antihyperglycemic effects through three primary mechanisms at the cellular and organ level:
Hepatic Regulation: It inhibits gluconeogenesis and glycogenolysis, effectively reducing the amount of glucose produced and released by the liver.
Muscle Sensitivity: It increases peripheral insulin sensitivity, allowing skeletal muscles to take up and utilize glucose from the bloodstream more efficiently.
Intestinal Absorption: It delays the absorption of glucose within the gastrointestinal tract.
Unlike many other antidiabetic agents, metformin does not cause hypoglycemia in monotherapy because it does not stimulate insulin secretion. Additionally, it has beneficial effects on lipid metabolism, helping to lower total cholesterol and triglycerides.
Type 2 Diabetes Mellitus: Primary treatment when diet and exercise are insufficient.
Adult Monotherapy & Combination: Used alone or alongside insulin and other oral hypoglycemic drugs.
Pediatric Care: Indicated for children aged 10 years and older and adolescents.
Complication Prevention: First-line preparation to reduce diabetes-related risks in overweight patients.
Hypersensitivity to metformin hydrochloride or any tablet components.
Acute Metabolic Acidosis: Including lactic acidosis or diabetic ketoacidosis.
Diabetic Precoma.
Severe Renal Impairment: Glomerular filtration rate (GFR) < 30 ml/min.
Acute Conditions: Dehydration, severe infection, or shock that may compromise renal function.
Adults:
Initial Dose: 500 mg or 850 mg administered 2–3 times daily.
Titration: After 10–15 days, the dose should be adjusted based on blood glucose monitoring.
Maximum Dose: Typically up to 3000 mg per day in divided doses.
Children (10 years and older):
Initial Dose: 500 mg or 850 mg once daily.
Titration: Adjustments based on glucose levels after 10–15 days.
Timing: Always take tablets during or after meals.
Gastric Protection: A slow increase in the dose is essential to minimize gastrointestinal side effects.
Gastrointestinal (Very Common): Nausea, vomiting, diarrhea, and abdominal pain, especially at the start of therapy.
Metabolic: Lactic acidosis (rare but serious).
Nervous System: Taste disturbances (metallic taste).
Skin: Reactions such as erythema (redness), itching, or urticaria.
Hepatobiliary: Rare reports of hepatitis or impaired liver function indicators, which resolve after stopping the drug.
Dietary Adherence: Patients must maintain a low-calorie diet and a uniform intake of carbohydrates throughout the day.
Lactic Acidosis: This is a medical emergency. Avoid excessive alcohol and be cautious during conditions that cause tissue hypoxia (e.g., heart failure).
Monitoring: Regular carbohydrate metabolism indicators and kidney function tests are mandatory.
Driving: Monotherapy does not affect reaction speeds; however, use caution if combined with insulin or sulfonylureas due to hypoglycemia risks.
Store in the original packaging at a temperature not higher than 25°C.
Keep out of the reach of children.
Shelf Life: Refer to the expiration date on the packaging (typically 3–5 years).
