To your health. In the 80s, biological medicines burst onto the market, a new type of drugs that, unlike the traditional synthetic and chemical ones, used living organisms for their development. Biologicals represented an important change in the way of dealing with pathologies such as diabetes, diseases of autoimmune origin, dwarfism or cancer. In the early 2000s, biologic drugs that emerged in the 80s began to lose their patents. This is how biosimilars appeared: drugs of biological origin manufactured from a version of the same active principle as its reference biological and which have demonstrated equivalence with it in terms of efficacy, safety and quality.
