Question

Select the probable mechanism of absorption of a hydrophilic drug of molecular weight 80 dalton.

• A. Active transport
• B. Filtration
• C. Passive diffusion
• D. Endocytosis

Hint:

Small, hydrophilic drugs → filtration across capillary membranes.

Answer 1

The Correct Option is B

Hydrophilic drugs with low molecular weight (like 80 Da) are typically absorbed through filtration (also known as paracellular transport), where they pass through water-filled pores between cells.
