Understanding Glucophage SR: The Extended-Release Metformin
Glucophage SR, an extended-release formulation of metformin, is a cornerstone in the management of Type 2 diabetes. This medication, renowned for its efficacy in lowering blood sugar levels, is prescribed globally to millions of individuals aiming to control their diabetes effectively. In this comprehensive guide, we delve into the mechanisms, uses, dosages, and potential side effects of Glucophage SR.
What is Glucophage SR?
Glucophage SR is the extended-release (SR stands for sustained release) version of metformin hydrochloride. It belongs to the class of medications known as biguanides, which are primarily used to lower glucose production in the liver and increase insulin sensitivity in muscle cells. This dual action helps in reducing blood sugar levels effectively.
Mechanism of Action
The primary function of Glucophage SR is to decrease hepatic glucose output and enhance peripheral insulin sensitivity. It achieves this by activating AMP-activated protein kinase (AMPK), an enzyme that plays a significant role in cellular energy homeostasis. By doing so, it not only lowers glucose production but also improves glucose uptake by muscles.
Indications for Use
- Management of Type 2 diabetes in adults and children over 10 years of age
- Polycystic Ovary Syndrome (PCOS) – off-label use
- Prevention of Type 2 diabetes in individuals with prediabetes – off-label use
It’s crucial to note that Glucophage SR should be used in conjunction with a proper diet and exercise regimen to achieve optimal results.
Dosage and Administration
Glucophage SR is typically started at a low dose to minimize gastrointestinal side effects, with gradual increments as tolerated. The commonly recommended starting dose is 500 mg once daily with the evening meal. Depending on the patient’s response, the dose can be increased up to a maximum of 2000 mg per day.
| Dosage | Frequency |
|---|---|
| 500 mg | Once daily |
| 1000 mg | Once daily or divided doses |
| 2000 mg | Once daily or divided doses |
Always follow your healthcare provider’s instructions regarding dosage adjustments.
Possible Side Effects
While Glucophage SR is generally well-tolerated, some individuals may experience side effects. Common side effects include:
- Gastrointestinal issues like nausea, vomiting, and diarrhea
- Metallic taste in the mouth
- Loss of appetite
In rare cases, Glucophage SR can cause lactic acidosis, a serious condition that requires immediate medical attention. Symptoms of lactic acidosis include muscle pain, difficulty breathing, and feeling extremely tired.
Comments from Healthcare Professionals
“Glucophage SR is a vital component in diabetes management due to its ability to control blood sugar levels without causing weight gain. Its extended-release formulation improves patient compliance by reducing the frequency of dosing,” says Dr. Emily Johnson, an endocrinologist.
“Patients with Type 2 diabetes benefit significantly from Glucophage SR, especially when lifestyle modifications are also implemented. It’s important for patients to adhere to their prescribed dosage and report any unusual symptoms to their healthcare provider,” advises pharmacist Mark Thompson.
