Mechanisms of Action for Each Medication

Metformin lowers blood sugar levels by decreasing hepatic glucose production and enhancing insulin sensitivity in peripheral tissues. It primarily acts on the liver, where it inhibits gluconeogenesis, reducing glucose release into the bloodstream. Additionally, Metformin increases glucose uptake in muscle cells, which improves glucose utilization.

Metformin

  • Reduces hepatic glucose output through inhibition of gluconeogenesis.
  • Enhances insulin sensitivity in muscle and fat tissues.
  • May improve gut microbiota, contributing to better metabolic health.

Acarbose functions by inhibiting alpha-glucosidase, an enzyme responsible for breaking down carbohydrates into glucose in the intestine. This action slows down carbohydrate digestion and absorption, leading to a reduction in postprandial blood glucose levels. Acarbose is particularly effective after meals, helping to manage spikes in blood sugar.

Acarbose

  • Inhibits alpha-glucosidase, delaying carbohydrate digestion.
  • Reduces postprandial blood glucose spikes.
  • May promote a favorable shift in gut microbiota, which can benefit overall metabolism.
