After taking ceain medications a patient noticed yellowing of eyes. Which of the following most often causes cholestatic jaundice?

A
INH
B
Erythromycin estolate
C
Pyrazinamide
D
Ethionamide
High-Yield Explanation
Cholestatic jaundice caused by erythromycin estolate (and rarely by the stearate) appears to be specifically related to the propionyl ester linkage of the 29 position. Thus, a history of cholestatic jaundice during therapy with oral erythromycin estolate is not an absolute contraindication to intravenous therapy with erythromycin gluceptate or lactobionate.
