1. Introduction to Metformin: The Diabetes Staple

Metformin is a first-line medication for type 2 diabetes, known for its effectiveness in lowering blood sugar. As an oral hypoglycemic agent, it works by reducing glucose production in the liver and improving insulin sensitivity. Its active ingredient, metformin hydrochloride , has been a cornerstone of diabetes treatment since the 1950s.

Key Features:

• Generic availability reduces costs.
• FDA-approved for diabetes and PCOS.
• Requires a prescription in most countries.

Why It Works:

• Inhibits gluconeogenesis.
