World Health Organization (WHO)

Erythromycin estolate, a macrolide antibiotic, was introduced in 1958 for the treatment of gram-positive infections. By the early 1970s its use had been associated with a higher incidence of hepatic toxicity than that seen with other salts and esters of erythromycin. This led to its withdrawal by some regulatory authorities whereas others required the addition of a warning in the product information. Evidence that the estolate ester is more hepatotoxic than other salts or esters has subsequently been disputed. It has been claimed to be the most effective ester for treatment of Legionnaire's disease and preparations remain widely available. (Reference: (BMJOAE) British Medical Journal, 286, 1954, 1983)

General Description

Erythromycin estolate, erythromycin propionate lauryl sulfate(Ilosone), is the lauryl sulfate salt of the 2'-propionateester of erythromycin. Erythromycin estolate is acid stableand absorbed as the propionate ester. The ester undergoesslow hydrolysis in vivo. Only the free base binds to bacterialribosomes. Some evidence, however, suggests that theester is taken up by bacterial cells more rapidly than thefree base and undergoes hydrolysis by bacterial esteraseswithin the cells. The incidence of cholestatic hepatitis is reportedlyhigher with the estolate than with other erythromycinpreparations.
Erythromycin estolate occurs as long needles that aresparingly soluble in water but soluble in organic solvents. administration for the treatment of serious infections,such as Legionnaires disease, or when oral administrationis not possible. Solutions are stable for 1 week whenrefrigerated.
