Which of the following drugs has a filter requirement due to particle formulation?

  1. Amphotericin B (lipid formulations; 5 micron)

  2. Dexmedetomidine

  3. Valproate

  4. Furosemide

The correct answer is: Amphotericin B (lipid formulations; 5 micron)

Amphotericin B is the correct answer because it requires a filter due to its particle formulation. The lipid formulations of Amphotericin B have larger particles (5 micron) that can cause harm if administered without filtration. The other options, Dexmedetomidine, Valproate, and Furosemide, do not have particle formulation concerns that necessitate a filter requirement for administration.
