Alcohol causes pain and tissue damage at the site of injection. Roquette has developed a pyrogen-free range of products with high pharmaceutical standards and being biocompatible for the manufacture of parenteral preparations, All these pyrogenfree range of products are obtained from natural and renewable raw materials.
