Biopharmaceuticals and traditional drugs are different in some important ways, especially in how they are given to patients. Let’s take a closer look:

1. What They Are Made Of

• Biopharmaceuticals: These are usually large and complex molecules. They include proteins, antibodies, and nucleic acids. Because they are so big, they don’t get absorbed well in the stomach and intestines.

• Traditional Drugs: These are smaller molecules. They can be made into different forms like pills or liquids and are easier to take by mouth.

2. How They Are Given

• Common Ways to Give Biopharmaceuticals:

  • Subcutaneous Injection: This is a common method and is pretty easy to do. It allows the medicine to be released slowly into the body.
  • Intravenous (IV) Infusion: This method is often used when doctors need to give an exact dose quickly, especially in emergency situations.
  • Intramuscular (IM) Injection: This method strikes a balance between how quickly the medicine is absorbed and how easy it is to give.

• Common Ways to Give Traditional Drugs:

  • Oral: Pills, capsules, and syrups are popular because they are convenient and easy to take.
  • Topical: Creams and patches are used when the medicine only needs to work on a specific area of the body.

3. How Well They Are Absorbed

• Biopharmaceuticals usually don’t get absorbed well when taken by mouth because they can break down in the stomach. That’s why doctors often choose other methods to give them.

• On the other hand, traditional drugs can be made to work well when taken by mouth, making it easier for patients to follow their treatment plans.

These differences show how biopharmaceuticals and traditional drugs are designed for different needs, and how they must be given in special ways to be effective.
