Multiple choice

Which of the following is an example of a biopharmaceutical?

  1. Aspirin

  2. Insulin

  3. Ibuprofen

  4. Acetaminophen
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Insulin is a biopharmaceutical because it is produced using recombinant DNA technology, which involves the insertion of a gene encoding human insulin into a host organism, such as bacteria or yeast.

Multiple choice

Which of the following is an example of a monoclonal antibody biopharmaceutical?

  1. Rituximab

  2. Trastuzumab

  3. Bevacizumab

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rituximab, trastuzumab, and bevacizumab are all examples of monoclonal antibody biopharmaceuticals. These drugs are produced using hybridoma technology, which involves the fusion of a B cell with a myeloma cell to create a hybridoma cell that can produce monoclonal antibodies.

Multiple choice

What is the primary mechanism of action of antihistamines in allergy treatment?

  1. Inhibiting the release of inflammatory mediators

  2. Blocking the binding of IgE to mast cells

  3. Reducing the production of Th2 cytokines

  4. Preventing the activation of eosinophils
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Antihistamines work by blocking the binding of IgE to mast cells, preventing the release of inflammatory mediators.

Multiple choice

  1. Inhibiting the release of inflammatory mediators

  2. Blocking the binding of IgE to mast cells

  3. Reducing the production of Th2 cytokines

  4. Preventing the activation of eosinophils
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Leukotriene modifiers work by inhibiting the release of inflammatory mediators, such as leukotrienes, from activated cells.

Multiple choice

  1. Inhibiting the release of inflammatory mediators

  2. Blocking the binding of IgE to mast cells

  3. Reducing the production of Th2 cytokines

  4. Preventing the activation of eosinophils
Reveal answer Fill a bubble to check yourself
Correct answer
Explanation

Cromolyn sodium works by preventing the binding of IgE to mast cells, stabilizing mast cells, and inhibiting the release of inflammatory mediators.
