Certain drugs cannot pass the blood-brain barrier (BBB) due to their molecular size or polarity. Examples include large molecules like monoclonal antibodies, and hydrophilic substances. Understanding the BBB is crucial for developing treatments for neurological diseases.

FAQs & Answers

  1. What is the blood-brain barrier? The blood-brain barrier is a protective shield that prevents potentially harmful substances in the bloodstream from entering the brain.
  2. Why can't some drugs cross the blood-brain barrier? Some drugs cannot cross the blood-brain barrier due to their molecular size, polarity, or lack of specific transport mechanisms.
  3. What are examples of drugs that can't pass through the blood-brain barrier? Examples include large molecules like monoclonal antibodies and hydrophilic substances that are unable to penetrate the barrier.
  4. How does the blood-brain barrier affect drug development? Understanding the blood-brain barrier is crucial for developing effective treatments for neurological diseases, as it limits the types of molecules that can be used.
