Lantus SoloStar insulin injection

Lantus is a well-known brand of insulin glargine, a long-acting basal insulin used to improve blood sugar control in adults and children with diabetes. The SoloStar variant refers to the pre-filled, disposable insulin pen delivery system shown in the image.

The brand was developed by the pharmaceutical company Sanofi (formerly Sanofi-Aventis). Originally launched in the early 2000s, Lantus became one of the most widely used insulin products globally. While the brand originated with Sanofi in France and Germany, the manufacturing of the insulin and the assembly of the SoloStar pens predominantly take place in Sanofi's major industrial facilities in Frankfurt, Germany, though the company maintains a global supply chain.

Sanofi remains the ultimate owner and manufacturer of Lantus. As a global biopharmaceutical leader headquartered in Paris, Sanofi operates across various therapeutic areas, including immunology, oncology, and rare diseases, while maintaining a significant legacy in diabetes care through the Lantus brand.
