Tag: Biological barriers

An estimated 98% of small molecule drugs fail to cross the blood-brain barrier, highlighting a key physiological obstacle to effective treatment. Understanding **what are the barriers of drugs** is crucial for developing new pharmaceuticals and optimizing existing therapies, as these hurdles can affect everything from absorption to patient adherence.

Biological barriers like the blood-brain barrier and thick mucosal layers present major obstacles for therapeutics, hindering effective treatment. Understanding **what are the barriers to drug delivery** is critical for developing more effective medication strategies and nanocarrier systems.
