ヘキサデカン酸(2R,3R)-2-(ジクロロアセチルアミノ)-3-ヒドロキシ-3-(4-ニトロフェニル)プロピル

説明Chloramphenicol palmitate is an orally bioavailable ester prodrug form of the antibiotic chloramphenicol. It is hydrolyzed in the small intestine to release chloramphenicol. Formulations containing chloramphenicol palmitate were previously used in the treatment of severe bacterial infections.

使用Chloramphenicol palmitate is prepared by acylation of chloramphenicol with palmitic acid. Although chloramphenicol palmitate is a more hydrophobic drug which should enhance bioavailability, the primary advantage of the ester is to mask the taste of chloramphenicol in oral formulations. Chloramphenicol palmitate is significantly less active than chloramphenicol but acts as a prodrug, being readily hydrolysed by acid and esterase in the gut to release chloramphenicol.

一般的な説明Chloramphenicol palmitate is the palmitic acid ester ofchloramphenicol. It is a tasteless prodrug of chloramphenicolintended for pediatric use. The ester must hydrolyze invivo following oral absorption to provide the active form.Erratic serum levels were associated with early formulationsof the palmitate, but the manufacturer claims that thebioavailability of the current preparation is comparable tothat of chloramphenicol itself.
