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.
