Generic Micronase Information

Introduction

Micronase is a prescription medication used to improve blood‑glucose control in adults with type 2 diabetes mellitus (T2DM). Its active ingredient is glyburide, a member of the sulfonylurea class that stimulates insulin release from pancreatic β‑cells. In Hong Kong, Micronase is listed under the Department of Health’s Drug Formulary and is prescribed when diet, exercise, and first‑line agents such as metformin do not achieve target glycaemic levels. The drug is supplied by several manufacturers worldwide and is sometimes obtained through international pharmacies to supplement local availability.

What is Micronase?

Micronase is a tablet formulation containing the sulfonylurea glyglyburide (glyburide). It belongs to the second‑generation sulfonylureas, which are more potent and have a longer half‑life than first‑generation agents. The product is marketed by multiple pharmaceutical companies; the original brand name was registered by Boehringer Ingelheim. Generic versions containing the same active compound are widely available and are chemically identical to the branded product. In Hong Kong, the medication is classified as a prescription‑only medicine and is regulated by the Pharmacy and Poisons Board.

How Micronase Works

Glyburide binds to the sulfonylurea receptor (SUR1) on the pancreatic β‑cell membrane. This binding closes ATP‑sensitive potassium (K_ATP) channels, leading to cell depolarization. The depolarization opens voltage‑dependent calcium channels, causing an influx of calcium ions. Elevated intracellular calcium triggers exocytosis of insulin‑containing granules, thereby increasing circulating insulin levels independent of ambient glucose. The rise in insulin reduces hepatic glucose production and enhances peripheral glucose uptake, resulting in lower blood‑glucose concentrations. Onset of action typically occurs within 30–60 minutes after oral ingestion, with peak effects at 2–4 hours and a duration of 12–24 hours. Glyburide is metabolised primarily by hepatic cytochrome P450 enzymes (CYP2C9) and eliminated in urine.

Conditions Treated with Micronase

• Type 2 Diabetes Mellitus (T2DM): Micronase is approved as an adjunct to diet and exercise for adults whose glycaemic targets (HbA1c < 7 % or individualized goals) are not met with monotherapy.
• Gestational Diabetes (off‑label in selected cases): Some clinicians may consider low‑dose glyburide for gestational diabetes when insulin is not feasible, though close fetal monitoring is required.

In Hong Kong, the prevalence of T2DM is estimated at 9–10 % of adults, reflecting the region’s ageing population and lifestyle risk factors. Effective glycaemic control reduces the risk of microvascular complications (retinopathy, nephropathy, neuropathy) and macrovascular disease (heart attack, stroke), aligning with the Hong Kong Hospital Authority’s diabetes management guidelines.

Who is Micronase For?

Micronase is appropriate for adult patients with T2DM who:

• Have inadequate glycaemic control on metformin alone or metformin + another oral agent.
• Prefer an oral agent over injectable insulin when lifestyle measures are insufficient.
• Possess preserved β‑cell function, as sulfonylureas require functional insulin‑producing cells to be effective.

Contra‑indications include patients with a history of severe hypoglycaemia, type 1 diabetes, diabetic ketoacidosis, significant renal impairment (eGFR < 30 mL/min/1.73 m²), or known hypersensitivity to sulfonylureas. Caution is advised in the elderly, individuals with hepatic insufficiency, and those taking interacting medications (e.g., fluoroquinolone antibiotics, azole antifungals).

Risks, Side Effects, and Interactions

Common

• Hypoglycaemia: The most frequent adverse event, especially if meals are skipped, alcohol is consumed, or dosing is not adjusted.
• Weight gain: Approximately 1–3 kg may be added due to increased insulin‑mediated glucose storage.
• Gastrointestinal discomfort: Nausea, dyspepsia, or abdominal pain can occur but are usually mild.

Rare

• Skin reactions: Rash, pruritus, or urticaria may develop; discontinuation is advised if severe.
• Hepatotoxicity: Transient elevations in liver enzymes have been reported; routine monitoring is recommended for patients with pre‑existing liver disease.

Serious

• Severe hypoglycaemia: Can lead to loss of consciousness, seizures, or accidents; requires immediate medical attention.
• Allergic anaphylaxis: Rare but life‑threatening; manifested by swelling of the face/tongue, difficulty breathing, or hypotension.

Clinically Relevant Drug–Drug Interactions

• CYP2C9 inhibitors (e.g., fluconazole, trimethoprim‑sulfamethoxazole) may increase glyburide plasma concentrations, heightening hypoglycaemia risk.
• CYP2C9 inducers (e.g., rifampicin, carbamazepine) can reduce efficacy.
• Concurrent use with other hypoglycaemic agents (e.g., insulin, metformin, DPP‑4 inhibitors) requires dose adjustment and vigilant glucose monitoring.
• Alcohol potentiates hypoglycaemic episodes; patients should limit intake and avoid binge drinking.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dosing: Typically 2.5 mg to 5 mg once daily with the first main meal. The dose may be titrated every 1–2 weeks based on fasting plasma glucose and HbA1c, not exceeding 20 mg per day.
• Administration: Take the tablet whole with a full glass of water; food enhances absorption and reduces hypoglycaemia risk.
• Missed dose: If a dose is forgotten and the usual dosing time is within 12 hours, take the missed tablet as soon as remembered. Skip it if the next scheduled dose is imminent to avoid double dosing.
• Overdose: Symptoms include severe hypoglycaemia, dizziness, sweating, and possible loss of consciousness. Immediate treatment involves oral glucose (if the patient is conscious) or intravenous dextrose administered by healthcare personnel. Call emergency services without delay.

Precautions:

• Adjust dose in renal or hepatic impairment; reduce to the lowest effective dose.
• Monitor blood glucose regularly, especially when initiating therapy or changing concomitant medications.
• Avoid grapefruit juice, which can inhibit CYP metabolism and increase drug levels.

FAQ

• What is the typical appearance of Micronase tablets?
  Micronase tablets are usually round or oval, white to off‑white, and imprinted with the strength (e.g., “2.5 mg”) and the manufacturer's logo. The exact shape and color may vary between generic manufacturers, but all contain the same active ingredient, glyburide.

• Can Micronase be stored in a bathroom cabinet?
  It should be kept at controlled room temperature (15 °C–30 °C), away from excess moisture and direct sunlight. A bathroom cabinet, which often experiences high humidity, is not recommended because moisture can degrade the tablet's stability over time.

• Is it safe to travel internationally with Micronase?
  Yes, provided the medication is kept in its original packaging with a copy of the prescription or a physician’s letter if required by customs. For long flights, store the tablets in your carry‑on bag to avoid temperature extremes in the cargo hold.

• Does Micronase contain any allergens such as lactose or gluten?
  In most formulations, the inactive ingredients include microcrystalline cellulose, magnesium stearate, and lactose. Patients with severe lactose intolerance should verify the specific product batch with the supplier before use.

• How does glyburide differ from other sulfonylureas like glipizide?
  Glyburide has a longer half‑life and higher potency, which can increase hypoglycaemia risk, especially in the elderly or those with renal dysfunction. Glipizide has a shorter duration of action and is sometimes preferred for patients who require tighter control of hypoglycaemia.

• Can Micronase affect results of laboratory tests?
  Glyburide does not typically interfere with standard blood chemistry panels. However, it may cause false‑low glucose readings in point‑of‑care glucometers if the sample is taken during a hypoglycaemic episode.

• Are there special warnings for Asian populations?
  Studies suggest that Asian patients may have a higher susceptibility to sulfonylurea‑induced hypoglycaemia due to differences in body composition and dietary patterns. Dose titration should start at the lower end (2.5 mg) and be adjusted cautiously.

• What is the shelf life of Micronase after opening the package?
  Unopened tablets retain full potency for up to 24 months when stored properly. Once the bottle is opened, it is advisable to use the medication within 12 months and to keep the cap tightly closed to limit exposure to moisture.

• Is there a difference between Micronase tablets sold in the United States versus Asia?
  The active dose of glyburide is identical worldwide, but excipients such as binders and colorants may differ to comply with regional regulatory requirements. These variations typically do not affect therapeutic efficacy but could influence tolerability in sensitive individuals.

• Can Micronase be purchased without a prescription in Hong Kong?
  No. Micronase is classified as prescription‑only medication under Hong Kong law. While our online pharmacy facilitates access for patients with a valid prescription, the drug cannot be legally dispensed without one.

• How does temperature affect the stability of Micronase during shipment?
  Glyburide tablets are stable at ambient temperatures but may degrade if exposed to extreme heat (>40 °C) for prolonged periods. Our shipping process includes temperature‑controlled packaging to maintain product integrity during transit.

• What should I do if I experience a mild hypoglycaemic episode while taking Micronase?
  Consume 15 g of fast‑acting carbohydrate (e.g., glucose tablets, fruit juice) and re‑check blood glucose after 15 minutes. If symptoms persist or glucose remains below 70 mg/dL, repeat the carbohydrate intake and seek medical advice if the condition does not improve.
