Description

Erythromycin Lactobionate (200 Mg) is a water-soluble salt form of the macrolide antibiotic erythromycin, specifically designed for parenteral administration. This high-purity pharmaceutical intermediate is critical for formulating sterile injectable solutions used in hospital and clinical settings. It is essential for manufacturers in the pharmaceutical industry requiring a reliable and compliant active pharmaceutical ingredient (API) for antibiotic production.

Application

• Pharmaceutical API: Primary use as the active ingredient in sterile injectable antibiotic formulations.
• Hospital Intravenous Solutions: For the preparation of IV infusions to treat severe bacterial infections, including respiratory tract, skin, and soft tissue infections.
• Lyophilized (Freeze-Dried) Powder Formulations: Used in the manufacture of stable, reconstitutable powder vials for extended shelf-life.
• Veterinary Injectable Products: Formulation of antibiotic treatments for livestock and companion animals.
• Research & Development: Serves as a reference standard and starting material in pharmaceutical R&D for new antibiotic delivery systems.
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for production of generic and branded injectable drugs.

Quality Control

Our Erythromycin Lactobionate is manufactured under strict quality systems suitable for pharmaceutical use. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and potency. Certificates of Analysis (COA) documenting compliance with relevant pharmacopeial standards (such as USP/EP) are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption and degradation.
