Explanation

Glomerular filtration is primarily affected by the extent to which a drug binds to plasma proteins. Only the unbound (free) fraction of the drug can be filtered through the glomerulus, whereas lipid solubility, ionization, and tubular secretion impact other aspects of drug handling but do not directly affect glomerular filtration.
