Metformin-Astrafarm 1000 mg is a potent biguanide antihyperglycemic medication designed for the management of Type 2 Diabetes Mellitus. It is highly effective for patients with excess body weight who have not achieved adequate glycemic control through diet and exercise alone. By targeting hepatic glucose production and improving peripheral insulin sensitivity, Metformin-Astrafarm provides a robust clinical foundation for preventing diabetes-related complications. This high-dosage formulation is ideal for patients requiring significant glycemic regulation, either as a standalone therapy or as part of a complex regimen involving insulin or other oral hypoglycemic drugs.
(Note: While some clinical documents may list the strength as 1000 mg, always verify with the physical packaging as metformin is most commonly distributed in 500 mg, 850 mg, and 1000 mg increments.)
Each film-coated tablet contains:
Active Substance: Metformin hydrochloride — 1000 mg.
Inactive Ingredients: Povidone, magnesium stearate.
Coating: Hydroxypropylmethylcellulose 2910, 5sPz, PEG 6000, and titanium dioxide.
Metformin works via several sophisticated cellular mechanisms to lower blood sugar without increasing insulin secretion:
Hepatic Inhibition: It reduces the liver's production of glucose by inhibiting gluconeogenesis and glycogenolysis.
Peripheral Uptake: It enhances insulin sensitivity in skeletal muscles, facilitating more efficient glucose absorption and utilization.
Gastrointestinal Delay: It slows the absorption of dietary glucose from the intestines.
Metformin also contributes to cardiovascular health by favorably influencing lipid profiles, typically reducing total cholesterol and LDL levels.
Primary Treatment for T2DM: For adults and children over 10 years of age.
Overweight Patients: Specifically indicated as first-line therapy to reduce the risk of macrovascular complications.
Combination Protocols: Highly effective when paired with insulin or other hypoglycemic agents (e.g., sulfonylureas).
Hypersensitivity to any component of the medication.
Renal Dysfunction: Glomerular filtration rate (GFR) < 45 ml/min/1.73 m².
Acute Metabolic Disorders: Diabetic ketoacidosis or precoma.
Hypoxic Conditions: Recent myocardial infarction, shock, respiratory failure, or heart failure.
Severe Infections: Conditions predisposing to kidney damage or dehydration.
Liver Impairment: Hepatic failure or chronic alcoholism.
For Adults:
Standard Regimen: Initial doses often start at 500 mg or 850 mg, eventually titrating up to 1000 mg tablets based on glycemic targets.
Maximum Daily Dose: 3000 mg per day, divided into three separate doses.
Titration: Dose adjustments should occur every 10–15 days following blood glucose analysis.
For Children (10+ Years):
Standard Regimen: Initial dose is usually 500 mg or 850 mg once daily.
Maximum Daily Dose: 2000 mg per day, divided into 2–3 doses.
Food Interaction: Tablets must be taken during or after a meal to significantly reduce gastrointestinal side effects.
Swallowing: Tablets should be swallowed whole with water; do not crush or chew.
Gastrointestinal (Very Common): Nausea, diarrhea, abdominal pain, and loss of appetite. These are usually transient and occur at the start of treatment.
Metabolic: Lactic acidosis (very rare, requires emergency hospitalization). Long-term use may cause Vitamin B12 deficiency.
Sensory: A metallic taste in the mouth.
Skin: Rare instances of skin redness or itching.
Lactic Acidosis Risk: While rare, it is life-threatening. Symptoms include muscle cramps, severe fatigue, and abdominal pain.
Iodinated Contrast: Metformin must be paused 48 hours before and after imaging procedures using iodinated contrast media.
Pregnancy: It is recommended to use insulin instead of metformin during pregnancy to ensure the tightest possible control of blood sugar levels.
Lactation: Breastfeeding is not recommended as metformin is excreted in breast milk.
Store in the original package at temperatures below 25°C.
