Chloramphenicol Palmitate Micronised
Chloramphenicol Palmitate Micronised is a micronized, lipophilic ester derivative of chloramphenicol, designed for improved solubility and bioavailability compared to the parent drug. It appears as a fine, white to off-white powder with enhanced surface area due to micronization. This antibiotic is widely used for oral formulations, particularly pediatric suspensions, due to its palatability and controlled release properties. Chloramphenicol Palmitate exhibits broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria. Its ester form offers better stability and reduced bitterness, making it a preferred choice in pharmaceutical preparations.
Chloramphenicol Palmitate Micronised Uses
Primary Uses
Pharmaceutical Industry
- Used as an active pharmaceutical ingredient (API) in oral antibiotic formulations such as suspensions and syrups.
- Preferred for pediatric use due to improved taste and ease of administration.
- Employed for treatment of serious bacterial infections including typhoid fever, meningitis, and respiratory tract infections.
- Used in veterinary medicine for similar bacterial infections in animals.
Formulation Benefits
- Micronization improves dissolution rate and bioavailability.
- The palmitate ester enhances lipophilicity and prolongs drug release, allowing sustained therapeutic levels.
Secondary Uses
Research & Development
- Used in pharmaceutical research for developing novel delivery systems and improving drug stability.
Veterinary Medicine
- Occasionally used in topical formulations for wound infections in animals.
