Mechanism & Pharmacology

Diaformin, officially known as metformin, belongs to the biguanide class of medications and is pivotal in managing Type 2 diabetes. Understanding how it works provides insight into its therapeutic benefits.

Simplified explanation

Diaformin primarily lowers blood glucose levels by improving insulin sensitivity. It reduces liver glucose production and enhances glucose uptake in muscles. This dual action helps to stabilise blood sugar levels, making it an essential tool for people with Type 2 diabetes. Unlike some other medications, Diaformin does not promote insulin release, reducing the risk of hypoglycaemia (low blood sugar). Furthermore, it may assist in weight management, making it a popular choice among patients.

Clinical terms

Understanding the pharmacological context of Diaformin enriches comprehension of its application. Key terms include:

• Biguanides: The class of drugs to which Diaformin belongs, primarily focusing on glucose metabolism.
• Insulin sensitivity: The ability of cells to respond to insulin, crucial for maintaining balanced blood sugar levels.
• Hepatic glucose output: The process by which the liver produces glucose; Diaformin aims to reduce this output.
• Lactic acidosis: A rare but serious side effect associated with metformin; awareness is key for safe usage.

Indications & Off-Label Uses

Diaformin is primarily prescribed for specific medical conditions, but its versatility extends beyond approved uses.

Approved indications by TGA

The Therapeutic Goods Administration (TGA) approves Diaformin for managing Type 2 diabetes, often as the first-line oral medication. Initial doses typically start at Diaformin 500 mg once or twice daily, which can be increased gradually based on individual tolerance and blood glucose levels. It effectively helps in achieving glycaemic control and is often part of a broader management plan that includes lifestyle modifications.

Off-label uses in Australian clinical practice

Beyond Type 2 diabetes, Diaformin is also used off-label, notably for Polycystic Ovary Syndrome (PCOS). In this context, it can help manage insulin resistance and regulate menstrual cycles. The typical off-label dosage size often falls between Diaformin 500 mg and 1500 mg per day, tailored to the individual’s needs.

Key Clinical Findings

Recent studies conducted in Australia have highlighted the effectiveness of Diaformin in diverse patient populations. Evidence suggests that Diaformin not only reduces blood glucose levels but also supports weight management, which is important for many diabetic patients. Ongoing research continues to investigate its potential benefits for conditions beyond diabetes, solidifying its status as a cornerstone of diabetes management.
