OBJECTIVE We aimed to compare the possible controlled release profile of multilamellar liposomal bupivacaine formulations with non-liposomal forms in artificial cerebrospinal fluid (CSF) under in vitro conditions. METHODS Liposome formulations were prepared using a dry-film hydration method. Then, an artificial CSF-buffered solution was prepared. Bupivacaine base with liposomal bupivacaine ba...

Sphingosine 1-phosphate (S1P) is a bioactive lipid known to control cell growth that was recently shown to act as a trophic factor for skeletal muscle, reducing the progress of denervation atrophy. The aim of this work was to investigate whether S1P is involved in skeletal muscle fiber recovery (regeneration) after myotoxic injury induced by bupivacaine. The postnatal ability of skeletal muscle...

BACKGROUND Liposome bupivacaine is a prolonged-release bupivacaine formulation indicated for single-dose administration into the surgical site to produce postsurgical analgesia. METHODS An overview of time to onset of analgesia observed with liposome bupivacaine in human studies is provided, as well as a summary of data from pharmacokinetic studies including those that assessed pharmacokineti...

BACKGROUND The susceptibility of children and newborns to cardiotoxicity from racemic bupivacaine, RS(±)-bupivacaine, is controversial. Some studies indicate that newborns can sustain higher bupivacaine plasma levels than adults, without severe toxicity. In this study, we compared the influence of age on cardiotoxicity from RS(±)-bupivacaine and S(-)-bupivacaine in rats. The effects of these lo...

BACKGROUND This report presents results from four preclinical studies evaluating safety and pharmacokinetics (PKs) of liposome bupivacaine following intravascular (intravenous [IV], intra-arterial [IA]), epidural, and intrathecal administration in dogs. METHODS Intravascular administration was initially tested in a pilot study to determine maximum tolerated doses, and then in an expanded stud...

objective: this study investigated the efficacy of bupivacaine wound infusion for pain control and opioid sparing effect after cesarean delivery. materials and methods: we conducted a randomized double blind, placebo controlled clinical trial on 60 parturients undergoing cesarean section at a university hospital in tehran. patients were randomized to receive a pump infusion system that was fill...

conclusions considering that tonsillectomy is one of the most common surgeries in children and produces a lot of pain, using a low risk medicine such as bupivacaine to recover child as soon as possible seems reasonable. results patients aged 4 to 13 years. the amount of postoperative pain was obviously less in the bupivacaine group than the other group. the mean time of postoperative fluid inta...
