Description
Erythromycin Stearate is the stearate salt form of erythromycin, a broad-spectrum, topical macrolide antibiotic with antibacterial activity. Erythromycin stearate diffuses through the bacterial cell membrane and reversibly binds to the 50S subunit of the bacterial ribosome. This prevents bacterial protein synthesis. Erythromycin stearate may be bacteriostatic or bactericidal in action, depending on the concentration of the drug at the site of infection and the susceptibility of the organism involved.

| General Description | Erythromycin stearate (Ethril, Wyamycin S, Erypar) is thestearic acid salt of erythromycin. Like erythromycin base,the stearate is acid labile. It is film coated to protect it fromacid degradation in the stomach. In the alkaline pH of theduodenum, the free base is liberated from the stearateand absorbed. Erythromycin stearate is a crystalline powderthat is practically insoluble in water but soluble in alcoholand ether. |
| Fluffy colorless powder or fine white powder. | |
| Air & Water Reactions | Insoluble in water. |
| Reactivity Profile | A base. Readily forms salts with acids. |
