Study Notes

History of Pharmaceutical Industry

The pharmaceutical industry dates back to the 19th century with companies like Bayer and Hoechst.
Key developments include the synthesis of aspirin in 1895, the discovery and chemical synthesis of sulfa drugs, and the industrial-scale production of penicillin in the 1940s.
The 1950s saw the production of proteins naturally found in the body for therapeutic use.
These included interferons, interleukins, erythropoietin, and neurotrophic factors.

Recombinant DNA Technology

Recombinant DNA technology revolutionized the production of proteins.
It allowed for the production of any protein in any quantity required, addressing the problem of source availability.
It overcame issues of product safety as direct extraction from native sources carried the risk of transmitting diseases such as hepatitis B, C, and HIV.
It provided an alternative to direct extraction from dangerous sources, such as snake venom or human pituitaries.
The use of RDT enabled the creation of engineered therapeutic proteins with clinical advantages over their native counterparts.
This was achieved through techniques like site-directed mutagenesis, which allowed insertions, deletions, or alterations of amino acid residues.

Pharmaceuticals and Biopharmaceuticals

Companies in the pharmaceutical and biopharmaceutical industry are involved in the research, development, manufacturing, and distribution of drugs.
Drugs are defined as products used to diagnose, cure, mitigate, treat, or prevent diseases.
Excipients are substances added to drugs to enhance their therapeutic properties and facilitate their manufacturing.
They can improve stability, bulking, absorption, solubility, handling, and flowability.
Pharmaceutical substances are typically low molecular mass organic chemicals synthesized directly from raw ingredients and then formulated into final products.

Biopharmaceuticals and Biologics

The term "biopharmaceutical" emerged in the 1980s.
It refers specifically to therapeutic proteins produced through biotechnological techniques, such as genetic engineering and hybridoma technology.
Recombinant human insulin (Humulin) was the first biopharmaceutical to be approved for therapeutic use in 1982.
Biopharmaceuticals are defined as protein or nucleic acid-based pharmaceutical substances produced by means other than direct extraction from natural sources.
Biologics are a broader category encompassing medicinal products derived from blood, vaccines, toxins, and allergen products.

Biotechnology Medicine and Biosimilars

Biotechnology medicine encompasses any pharmaceutical product produced using traditional or modern biotechnological methods for therapeutic or in vivo diagnostic purposes.
Biosimilars are biologic products highly similar to FDA-approved reference products, demonstrating no clinically meaningful differences in safety or effectiveness.
They are allowed minor differences in clinically inactive components.

Summary of Key Terms

Biotechnology: Using biological systems or molecules for commercial product production.
Biotechnology medicine: Pharmaceutical products produced through traditional or modern biotechnology.
Biologics: Medicinal products derived from blood, vaccines, toxins, and allergen products.
Biopharmaceutical: Protein or nucleic acid-based pharmaceutical substances produced by means other than direct extraction from natural sources.
Biosimilar: Biologic product highly similar to FDA-approved reference product, demonstrating no clinically meaningful differences in safety or effectiveness.
