Why Does Ceftriaxone Cause Biliary Sludging?

The concentration of ionized calcium in the bile is elevated and ceftriaxone can precipitate with calcium, like what occurs with bilirubin, and so ceftriaxone-associated biliary sludge

is mainly composed of a calcium-ceftriaxone complex.

Ceftriaxone-associated gallbladder pseudolithiasis is a not uncommon complication of this common antibiotic, where a ceftriaxone-calcium precipitate forms gallbladder sludge. It appears more common in pediatric patients.

Can ceftriaxone cause gallstones?
