ChEBI: Erythromycin estolate is an aminoglycoside sulfate salt and an erythromycin derivative. It has a role as an enzyme inhibitor. It contains an erythromycin A 2'-propanoate. | [Manufacturing Process]
16.7 grams of monopropionylerythromycin are dissolved in 50 ml of warm
acetone. To the solution are added 6.4 grams of sodium lauryl sulfate
dissolved in 50 ml of distilled water containing 2 ml of glacial acetic acid. The
white crystalline precipitate of rnonopropionylerythromycin lauryl sulfate which
separates is filtered off and dried. It melts at about 135° to 137°C. | [Brand name]

Antibacterial | [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. | [storage]
