Abstract:
The release and absorption profiles from the vagina of PGE2 in different vehicles used for cervical ripening and labour induction have been studied observing changes in concentrations of PGE metabolite (PGEM) and PGF metabolite (PGFM). In all groups a rise in PGEM concentration occurred over the 6 hour observation time but with wide variation. The profiles obtained differed markedly between the preparations under investigation correlating with the uterine contractions generated. PGFM generally showed little change. The model used could be explored further to enable modification of the vehicles used for PGE2 incorporation to achieve improved clinical results.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
