Generic Glucotrol Xl Information

Introduction

Glucotrol XL is an oral antihyperglycaemic agent indicated for the management of type 2 diabetes mellitus in adults. The tablet contains the sulfonylurea glipizide in an extended‑release formulation, allowing once‑daily dosing. In Hong Kong, Glucotrol XL is prescribed to improve glycaemic control when diet, exercise, and first‑line agents such as metformin do not achieve target blood glucose levels. The medication belongs to the diabetes drug class of sulfonylureas and is marketed by Boehringer Ingelheim.

What is Glucotrol XL?

Glucotrol XL is a brand‑name product that delivers the active compound glipizide in a prolonged‑release tablet. The drug is manufactured by Boehringer Ingelheim and registered with the Hong Kong Department of Health under the prescription category. Glipizide stimulates pancreatic β‑cells to release insulin, thereby lowering post‑prandial and fasting plasma glucose. The “XL” suffix denotes an extended‑release matrix that releases glipizide gradually over 24 hours, supporting consistent glycaemic control with a single daily dose.

How Glucotrol XL Works

Glipizide belongs to the sulfonylurea class, which binds to the sulfonylurea receptor (SUR1) on pancreatic β‑cells. This binding closes ATP‑sensitive potassium channels, leading to cell depolarisation and subsequent opening of voltage‑gated calcium channels. The influx of calcium triggers exocytosis of insulin granules. By increasing endogenous insulin secretion, Glucotrol XL reduces hepatic glucose output and enhances peripheral glucose uptake. The extended‑release matrix prolongs this pharmacodynamic effect, providing a steady insulinotropic stimulus for up to 24 hours after ingestion. Peak plasma concentrations are typically observed 4–6 hours after dosing, and the elimination half‑life ranges from 6 to 12 hours, depending on renal function.

Conditions Treated with Glucotrol XL

• Type 2 Diabetes Mellitus (T2DM) – Primary indication for adults who require additional glycaemic control beyond lifestyle measures and metformin.
• Adjunct Therapy in Combination Regimens – Used together with other oral agents (e.g., DPP‑4 inhibitors) or basal insulin when monotherapy is insufficient.

In Hong Kong, the prevalence of T2DM exceeds 10 % of the adult population, and a substantial proportion of patients progress to requiring sulfonylurea therapy after metformin failure. Glucotrol XL’s once‑daily dosing aligns with local clinical practice guidelines that emphasize simplicity to improve adherence.

Who is Glucotrol XL For?

• Adults with confirmed T2DM who have an HbA1c ≥ 7.5 % despite optimal metformin therapy.
• Patients who prefer a single‑daily dose and have reliable renal function (eGFR ≥ 30 mL/min/1.73 m²).
• Individuals without a history of severe sulfonylurea hypersensitivity or recurrent hypoglycaemia.

Glucotrol XL is not appropriate for:

• Patients with type 1 diabetes or diabetic ketoacidosis.
• Pregnant or lactating women (insulin is preferred).
• Individuals with significant hepatic impairment (Child‑Pugh C) or end‑stage renal disease requiring dialysis.

Risks, Side Effects, and Interactions

Common

• Hypoglycaemia – Often precipitated by missed meals, excessive alcohol, or concurrent insulin therapy.
• Gastro‑intestinal discomfort – Nausea, abdominal cramping, or diarrhoea.
• Weight gain – Usually modest, related to increased caloric retention from higher insulin levels.

Rare

• Hematologic changes – Leukopenia, neutropenia, or thrombocytopenia.
• Dermatologic reactions – Rash, pruritus, or photosensitivity.

Serious

• Severe hypoglycaemic episodes – May cause loss of consciousness, seizures, or accidents.
• Hypersensitivity syndrome – Fever, rash, eosinophilia, and organ involvement (liver, kidneys).
• Acute pancreatitis – Persistent abdominal pain with elevated serum amylase/lipase.

Clinically Relevant Drug–Drug Interactions

• Warfarin – Glipizide may enhance anticoagulant effect; monitor INR closely.
• Beta‑blockers – Can mask hypoglycaemia symptoms; adjust glucose monitoring frequency.
• Macrolide antibiotics (e.g., erythromycin, clarithromycin) – May increase glipizide plasma levels, raising hypoglycaemia risk.
• CYP2C9 inhibitors (e.g., fluconazole, amiodarone) – Reduce glipizide metabolism, necessitating dose reduction.

Patients should disclose all concomitant medicines, including over‑the‑counter products and herbal supplements, to avoid unintended interactions.

Practical Use: Dosing, Missed Dose, Overdose

• Starting dose – Typically 5 mg once daily with the first main meal. The tablet may be taken with or without food, but consistency with regard to meals is advisable.
• Dose titration – Based on fasting glucose and HbA1c, the dose can be increased in 5 mg increments every 2–4 weeks. The maximum usual dose is 20 mg daily.
• Missed dose – If a dose is forgotten and the next scheduled dose is >12 hours away, take the missed tablet as soon as remembered. Do not double the dose to compensate.
• Overdose – Symptoms include profound hypoglycaemia, dizziness, and tachycardia. Immediate treatment involves ingestion of fast‑acting carbohydrates, followed by medical evaluation. In severe cases, intravenous glucose may be required.

Precautions – Avoid excessive alcohol, which potentiates hypoglycaemia. Patients with renal impairment should start at a lower dose (e.g., 2.5 mg) and monitor blood glucose closely.

FAQ

• Is Glucotrol XL available in both brand‑name and generic forms in Hong Kong?
  Yes. While Glucotrol XL is the brand version produced by Boehringer Ingelheim, generic glipizide tablets with the same extended‑release profile are also approved and can be sourced from reputable suppliers.

• What should I do if I travel abroad with Glucotrol XL?
  Carry the medication in its original container with a copy of the prescription label. Keep it in your carry‑on luggage to avoid temperature extremes, and be aware that some countries require a doctor’s note for sulfonylureas.

• Does Glucotrol XL require refrigeration?
  No. The tablets should be stored at controlled room temperature (15 °C–30 °C), protected from moisture, light, and heat.

• How can I identify authentic Glucotrol XL tablets?
  Authentic tablets are pink, round, and imprinted with “GLUCOTROL XL” and the strength (e.g., “5 mg”). The packaging includes a batch number, expiry date, and a tamper‑evident seal.

• Are there any specific warnings for Asian populations?
  Pharmacokinetic studies indicate comparable exposure in Asian and Caucasian subjects, but clinicians advise cautious dose initiation in patients with lower body weight or reduced renal function, which can be more prevalent in certain Asian demographics.

• Can Glucotrol XL be imported for personal use in Hong Kong?
  Yes, personal import of a three‑month supply for a valid medical need is permitted under Hong Kong customs regulations, provided the product is accompanied by a prescription and meets the health authority’s quality standards.

• What inactive ingredients are present in Glucotrol XL?
  The extended‑release tablet contains microcrystalline cellulose, lactose monohydrate, magnesium stearate, and a polymer matrix (hydroxypropyl methylcellulose) that controls drug release.

• How does Glucotrol XL compare with earlier immediate‑release glipizide formulations?
  The extended‑release version provides smoother plasma concentrations, reducing peak‑related hypoglycaemia and allowing once‑daily dosing, whereas immediate‑release tablets often require twice‑daily administration with higher hypoglycaemia risk.

• What clinical trials established the efficacy of Glucotrol XL?
  Phase III double‑blind studies involving over 1,200 participants with inadequately controlled T2DM demonstrated a mean HbA1c reduction of 1.2 % versus placebo after 24 weeks, with a similar safety profile to immediate‑release glipizide.

• Is there any impact of Glucotrol XL on drug testing for employment?
  Sulfonylureas are not typically screened in standard occupational drug panels. However, if a specialized metabolic screening is performed, glipizide may be detected; informing the employer’s health program is advisable.
