Victoza is a medication belonging to the class of drugs known as GLP-1 receptor agonists. It is primarily prescribed to individuals with type 2 diabetes or those who require assistance with weight management. Victoza works by mimicking the effects of a hormone called GLP-1 (glucagon-like peptide-1) in the body.

As a GLP-1 receptor agonist, Victoza acts by binding to GLP-1 receptors found on various cells in the body. By activating these receptors, Victoza triggers a cascade of physiological effects. Firstly, it stimulates insulin release from pancreatic beta cells, which lowers blood glucose levels. This action is especially beneficial for individuals with type 2 diabetes who struggle with insulin secretion.

Secondly, Victoza suppresses glucagon release from the pancreas. Glucagon is a hormone that raises blood sugar levels by promoting the breakdown of glycogen stored in the liver. By inhibiting glucagon secretion, Victoza helps prevent excessive release of glucose into the bloodstream.

Furthermore, Victoza slows down the emptying of the stomach, reducing the rate at which carbohydrates are absorbed. This delayed absorption contributes to increased satiety, making it easier for individuals to manage their appetite and make healthier dietary choices.

The primary recipients of Victoza prescriptions are individuals diagnosed with type 2 diabetes. Type 2 diabetes is a chronic condition characterized by insulin resistance, resulting in high blood sugar levels. Victoza helps regulate blood sugar by increasing insulin secretion and reducing glucagon production. Furthermore, it slows down the rate at which food is absorbed in the stomach, leading to a sense of fullness and aiding weight management efforts.

Additionally, Victoza may also be prescribed to individuals struggling with weight management, even if they don’t have diabetes. In such cases, it can help reduce appetite and promote feelings of satiety, resulting in better control over food intake and potential weight loss.

Please note, Victoza does not come with needles.
