Biopharmaceuticals Explained

Unlike conventional drugs, which are usually made through chemical synthesis, biopharmaceuticals involve manipulating genetic materials and utilizing living cells. Biopharmaceuticals cover a wide range of products, including recombinant proteins, hormones like insulin, monoclonal antibodies, and vaccines. Here are some key differences between conventional pharmaceuticals and biopharmaceuticals:

• Production Method: Biopharmaceuticals use living organisms while conventional drugs rely on chemical synthesis.
• Composition: Biopharmaceuticals typically involve complex molecules while traditional pharmaceuticals consist of simpler molecules.
• Research and Development: The development of biopharmaceuticals involves advanced genetic engineering techniques.

Origin and History of Biopharmaceuticals

The advent of biopharmaceuticals began with the development of recombinant DNA technology in the 1970s. This groundbreaking invention paved the way for the production of human insulin using genetically engineered bacteria. Prior to this, insulin was extracted from animals, which often resulted in adverse reactions in some patients. The journey of biopharmaceuticals through history can be summarized in these stages:

• 1970s: Introduction of recombinant DNA technology.
• 1980s: Commercial production of human insulin and the first monoclonal antibodies.
• 1990s: Advancements in genetic engineering and development of more complex biopharmaceuticals like erythropoietin.
• 2000s-Present: Emergence of personalized medicine and continuous improvements in biopharmaceutical research and production.

Biopharmaceutical Research and Techniques

Biopharmaceutical research encompasses a wide range of modern techniques and advancements, bringing groundbreaking changes to the field of medicine.
