First drug product produced in LEF

LEF has already a drug product produced in its Manufacturing Unit. It is a veterinary medicine based on megestrol acetate, which aims to prevent the onset of heat in dogs and cats, as well as to stop lactation caused by pseudo-gestation. LEF ensures the total manufacture of the drug product, from the stage of mixing, compression, blistering, to the secondary packaging.

LEF has a new ICP-MS laboratory

​LEF has built a completely new laboratory which is designed to meet the new requirements of the pharmaceutical sector related to elemental impurities that can be found in medicines or similar products. The newly published guidelines require that the risk of certain elements, such as arsenic, cadmium, lead and mercury, be assessed in the final product.

Good Manufacturing Practices renewed

​​​​​​​INFARMED – National Authority of Medicines and Health Products, IP.  has renewed LEF's Good Manufacturing Practices (GMP) certification until 2019. With this certification, LEF ensures the fulfillment of all regulation requisites regarding manufacturing chain processes of non-sterile solids, semi-solids and liquids dosage forms, as well as certification and batch release.​
