What is Victoza?
Victoza contains the active ingredient liraglutide and belongs to the class of GLP-1 receptor agonists. It is used once daily as a subcutaneous injection to treat type 2 diabetes mellitus in adults.
Liraglutide mimics the body's own incretin hormone GLP-1, which is released after eating. It stimulates insulin release, inhibits glucagon release, and slows gastric emptying.
Victoza is manufactured by Novo Nordisk. A cardiovascular protective effect was demonstrated in the LEADER trial.
Active Ingredients & Mechanism of Action
Active ingredient: Liraglutid
Liraglutide acts as a GLP-1 receptor agonist:
Glucose-dependent insulin stimulation:
- Promotes insulin release only when blood sugar is elevated
- Hypoglycemia is possible even when used alone
Glucagon inhibition:
- Reduces glucagon release from the pancreas
- Less sugar released from the liver
Gastric emptying:
- Slowing of gastric emptying
- Flatter blood sugar spikes after meals
Satiety:
- Acts on the satiety center in the brain
- Supports weight loss

Victoza is suitable for:
- Adults with type 2 diabetes in combination with oral antidiabetic drugs
