Generic Glycomet

Introduction

Glycomet is a tablet formulation containing the biguanide drug metformin, prescribed primarily for the long‑term management of type 2 diabetes mellitus. In the United Kingdom, metformin is the first‑line oral hypoglycaemic recommended by the National Institute for Health and Care Excellence (NICE) because of its proven efficacy, safety profile, and favourable impact on cardiovascular risk factors. Glycomet is manufactured for distribution in the UK and is classified within the diabetes medication group. Although its main indication type 2 diabetes, metformin (and therefore Glycomet) is also used off‑label for conditions such as polycystic ovary syndrome (PCOS) and for pre‑diabetes management where lifestyle measures alone are insufficient.

What is Glycomet?

Glycomet is a solid oral dosage form that delivers a fixed dose of metformin hydrochloride. It is produced by a pharmaceutical company that complies with the UK Medicines and Healthcare products Regulatory Agency (MHRA) standards for quality, safety, and efficacy. Metformin is the active pharmaceutical ingredient (API); the tablets also contain excipients such as microcrystalline cellulose, magnesium stearate, and povidone, which aid in tablet formation and stability.

Metformin is available under several well‑known brand names worldwide, including Glucophage, Glucophage XR, and Glumetza. Glycomet offers the same active compound at a comparable potency, providing an alternative for patients seeking a reliable generic option.

How Glycomet

Metformin reduces hepatic glucose production (gluconeogenesis) and improves peripheral insulin sensitivity, especially in skeletal muscle and adipose tissue. The drug activates the enzyme AMP‑activated protein kinase (AMPK), a cellular energy sensor that promotes glucose uptake fatty‑acid oxidation while inhibiting lipogenesis. By lowering hepatic output and enhancing peripheral utilization, metformin decreases fasting plasma glucose and haemoglobin A1c (HbA1c) levels without directly stimulating insulin secretion.

Key pharmacokinetic points:

• Absorption: Approximately 50–60 % of an oral dose is absorbed from the small intestine; absorption is delayed but not reduced by food.
• Onset of action: Glycemic effects usually become apparent within 48–72 hours of the first dose.
• Elimination: Metformin is excreted unchanged by the kidneys; the renal clearance exceeds the glomerular filtration rate due to active tubular secretion.

Because metformin is not metabolised, drug–drug interactions are predominantly related to renal excretion or changes in gastrointestinal motility.

Conditions Treated with Glycomet

• Type 2 Diabetes Mellitus (T2DM): The principal indication. Glycomet is used to achieve target HbA1c levels in conjunction with diet, exercise, and other glucose‑lowering agents when required.
• Prediabetes (Impaired Fasting Glucose or Impaired Glucose Tolerance): NICE recommends metformin for individuals with a high risk of progression to T2DM when lifestyle modification alone is insufficient.
• Polycystic Ovary Syndrome (PCOS): Metformin improves insulin resistance, can restore ovulatory cycles, and may aid in weight management. Although not licensed specifically for PCOS in the UK, it is commonly prescribed off‑label based on clinical evidence.

In the UK, over 4 million adults live with diabetes, and metformin‑based regimens account for the majority of first‑line therapy, reflecting both clinical effectiveness and cost‑efficiency.

Suitable Candidates for Glycomet Treatment

• adults with newly diagnosed type 2 diabetes who have a body mass index (BMI) ≥ 25 kg/m² or who require glycaemic control without risk of hypoglycaemia.
• Patients inadequately controlled on diet and exercise alone (HbA1c ≥ 48 mmol/mol, 6.5 %).
• Individuals with pre‑diabetes who have confirmed impaired fasting glucose (6.1–6.9 mmol/L) or HbA1c 42–47 mmol/mol (6.–6.4 %) and who have not achieved normal glycaemia through lifestyle measures.
• Women with PCOS where insulin resistance contributes to anovulation, particularly when lifestyle changes fail to produce menstrual regularity.

Contra‑indications or situations where Glycomet should be avoided include:

• Severe renal impairment (eGFR < 30 mL/min/1.73 m²).
• Acute or chronic metabolic acidosis, including diabetic ketoacidosis.
• Known hypersensitivity to metformin or any tablet excipients.
• Pregnancy and breastfeeding, unless the benefits outweigh the risks and are agreed upon by a specialist.

Clinicians should assess renal function, hepatic status, and cardiac health before initiating therapy and periodically thereafter.

Risks, Side Effects, and Interactions

Common

• Gastro‑intestinal disturbances: nausea, diarrhoea, abdominal discomfort, and a metallic taste. These events typically occur during the first weeks of therapy and may be mitigated by dose titration and taking the tablet with meals.
• Vitamin B12 deficiency: long‑term use can reduce intestinal absorption of cobalamin, leading to mild anaemia or neuropathy. Annual B12 monitoring is advised for patients on metformin for more than three years.

Rare

• Dermatological reactions: rash, pruritus, or urticaria. Should these appear, the medication should be stopped and evaluated.
• Lactic acidosis: an uncommon but serious metabolic complication, characterised by rapid breathing, muscle pain, abdominal discomfort, and somnolence. The risk rises markedly in patients with renal insufficiency, hepatic disease, or conditions causing hypoxia.

Serious

• Severe hypoglycaemia: metformin alone does not cause hypoglycaemia; however, when combined with insulin or sulfonylureas, the risk may increase.
• Anaphylaxis: extremely rare. Immediate medical attention is required if signs of severe allergic reaction develop (e.g., swelling of the face, throat, or difficulty breathing).

Clinically Relevant Drug Interactions

• Renally cleared drugs: Cimetidine, trimethoprim, and pyrimethamine can reduce metformin elimination, increasing plasma concentrations.
• Contrast agents: Iodinated radiographic contrast can precipitate acute kidney injury, potentiating metformin‑associated lactic acidosis. Metformin should be withheld before and for 48 hours after contrast administration, with renal function reassessed before restarting.
• Alcohol: Excessive intake can potentiate lactic acidosis; patients should limit alcohol consumption.

Healthcare professionals must review the full medication list, including over‑the‑counter products and herbal supplements, before prescribing Glycomet.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dose: 500 mg taken once daily with the evening meal.
• Titration: Increase by 500 mg weekly or two‑weekly increments, aiming for the target dose of 150–200 mg per day divided into two or three doses, based on glycaemic response and tolerability.
• Maximum dose: 255 mg per day (commonly 850 mg three daily).

Missed dose:
If a dose is forgotten and it is less than 12 hours until the next scheduled dose, the missed tablet should be omitted. Do not double‑dose to compensate.

Overdose:
Acute ingestion of large amounts may cause severe gastrointestinal upset and, rarely, lactic acidosis. Immediate medical evaluation is required. Supportive care, including gastric lavage and activated charcoal, may be considered by clinicians.

Practical precautions:

• Take Glycomet with food to reduce GI upset.
• Avoid excessive alcohol consumption (no more than 14 units weekly).
• Maintain adequate hydration, especially in hot weather or during illness.
• Monitor renal function at baseline, after dose changes, and annually thereafter.

FAQ

• Is Glycomet available in both immediate‑release and extended‑release formulations?
  Glycomet is marketed as an immediate‑release tablet. Extended‑release metformin products, such as Glucophage XR, are sold under different brand names and may have distinct dosing schedules.

• Can Glycomet be stored in a refrigerator?
  No. Glycomet should be stored at controlled room temperature (15‑30 °C). Refrigeration is unnecessary and may cause condensation, potentially affecting tablet integrity.

• What does the Glycomet tablet look like?
  The tablets are round, white to off‑white, and bear the imprint “G‑500” (for the 500 mg strength). The appearance may vary slightly between manufacturers, but the imprint remains consistent for identification.

• Does Glycomet contain lactose or gluten?
  The standard formulation contains lactose as a filler. Patients with severe lactose intolerance should discuss alternatives with their healthcare provider. The tablets are gluten‑free.

• Are there any special customs rules when importing Glycomet for personal use in the UK?
  Personal import of a three‑month supply of a prescription medication for personal use is permitted under UK law, provided the product is for a legitimate medical need and the patient holds a valid prescription. Our service ensures that all documentation complies with HM Revenue & Customs regulations.

• Will taking Glycomet affect routine drug testing (e.g., for employment)?
  Metformin is not a controlled substance and does not appear on standard drug‑screening panels. It will not cause a positive result in typical employment or sports drug tests.

• Are there known formulation differences between EU and US metformin tablets?
  Both regions use the same active ingredient, but excipient profiles may differ slightly to meet local regulatory requirements. These differences do not usually affect clinical efficacy or safety.

• Why does long‑term metformin therapy sometimes lead to low vitamin B12 levels?
  Metformin interferes with calcium‑dependent membrane transport mechanisms in the ileum, reducing cobalamin absorption. Periodic monitoring of serum B12 is recommended, especially after several years of therapy.

• What historical milestone established metformin as the first‑line drug for type 2 diabetes?
  In 1998, the UK Diabetes Research Group published a meta‑analysis demonstrating metformin’s superior cardiovascular outcomes compared with sulfonylureas, leading NICE to recommend it as the initial pharmacologic treatment for newly diagnosed type 2 diabetes.

• How does metformin compare with sulfonylureas regarding hypoglycaemia risk?
  Metformin lowers glucose by improving insulin sensitivity and does not stimulate insulin secretion, making hypoglycaemia rare when used alone. Sulfonylureas directly increase insulin release, resulting in a higher incidence of low blood‑sugar episodes, especially in the elderly or those with irregular meals.

• Is it safe to take Glycomet while fasting for religious observances?
  Short‑term fasting (e.g., during Ramadan) may increase the risk of gastrointestinal side effects and, in rare cases, lactic acidosis in patients with reduced renal function. Patients should discuss dose timing and possible temporary dose reduction with their clinician before altering their regimen.
