Ester anesthetic metabolism
WebMar 13, 2015 · Poly(ester amide)s (PEAs) are nowadays one of the most promising synthetic materials for biomedical applications. Their excellent suitable properties are provided by the ester and amide linkages present in their structure. Ester units are hydrolytically cleavable and permit a better solubility in organic solvents. WebAn ester-linked local anesthetic agent, such as 2-chloroprocaine, is rapidly metabolized, and placental transfer is limited. Since the metabolism of 2-chloroprocaine by fetal plasma is slower than in maternal plasma, the potential for ion trapping exists. Fetal pH is slightly lower than maternal (7.32 to 7.38), thus most unionized drugs are ...

Until 1943 it was the only anaesthetic available.140 It is quickly and locally metabolized by an esterase, giving rise to the acid itself, which may act as an allergen. Its effect begins after 5–10 minutes and lasts approximately 45 minutes.
