Exploring the Contrasts Between Generic and Biological Drugs

🟢 1. What Are Generic Drugs?

• Made from small molecules with simple, fixed chemical structures.
• Chemically identical to the original branded drug.
• Same dosage, strength, safety, route, and use as the original.
• Inexpensive because companies don’t need to invest in original R&D.
• Example: Generic version of Disprin.

🔵 2. What Are Biological Drugs (Biologics)?

• Made from large, complex molecules (e.g., proteins, antibodies).
• Produced in living cells (e.g., bacteria, yeast).
• Much more expensive due to complex production and storage.
• Example: Insulin, monoclonal antibodies like Remicade.

🟠 3. What Are Biosimilars?

• Copies of biological drugs, but not identical due to biological complexity.
• Similar in function, safety, and efficacy to original biologics.
• Require more tests than generics to prove similarity.
• Cheaper than original biologics, but costlier than generics.
• Example: A biosimilar of Adalimumab (used for arthritis).
