Abstract
Many attempts have been made to increase the duration of local anesthetic action. One avenue of investigation has focused on encapsulating local anesthetics within carrier molecules to increase their residence time at the site of action. This article aims to review the literature surrounding the recently approved formulation of bupivacaine, which consists of bupivacaine loaded in multivesicular liposomes. This preparation increases the duration of local anesthetic action by slow release from the liposome and delays the peak plasma concentration when compared to plain bupivacaine administration. Liposomal bupivacaine has been approved by the US Food and Drug Administration for local infiltration for pain relief after bunionectomy and hemorrhoidectomy. Studies have shown it to be an effective tool for postoperative pain relief with opioid sparing effects and it has also been found to have an acceptable adverse effect profile. Its kinetics are favorable even in patients with moderate hepatic impairment, and it has been found not to delay wound healing after orthopedic surgery. More studies are needed to establish its safety and efficacy for use via intrathecal, epidural, or perineural routes. In conclusion, liposomal bupivacaine is effective for treating postoperative pain when used via local infiltration when compared to placebo with a prolonged duration of action, predictable kinetics, and an acceptable side effect profile. However, more adequately powered trials are needed to establish its superiority over plain bupivacaine.

Abstract
Local anesthetics are a cornerstone of multimodal pain control strategies in the surgical setting as they have a long history of use and an established safety profile. Although effective, their duration of action is relatively short, which usually leads to the use of other agents, such as opioids, for effective postsurgical pain control in most patients. A medical need exists to extend the duration of analgesia with local anesthetics to help reduce the reliance on opioids in the postsurgical setting. Liposomal bupivacaine uses a product delivery platform to release bupivacaine slowly over 96 hours after infiltration at the surgical site. Liposomal bupivacaine was compared with placebo in two pivotal, multicenter, randomized, double-blind, parallel-group trials in 189 adults undergoing soft-tissue surgery (hemorrhoidectomy) and 193 adults undergoing orthopedic surgery (bunionectomy). Among patients undergoing hemorrhoidectomy, liposomal bupivacaine significantly reduced cumulative pain scores for up to 72 hours (primary end point) as measured by the area under the curve of pain scores on the numeric rating scale (p<0.0001), reduced overall opioid consumption (p≤0.0006), increased the proportion of patients who did not receive opioids (p<0.0008), delayed time to first opioid by more than 13 hours (p<0.0001), and was associated with significantly higher rates of patient satisfaction (p=0.0007) compared with placebo. Similarly, in patients undergoing bunionectomy, liposomal bupivacaine significantly reduced total consumption of rescue opioids (p=0.0077) and cumulative pain scores as measured by the area under the curve of pain scores on the numeric rating scale (p=0.0005) during the first 24 postsurgical hours (primary end point) relative to placebo. Furthermore, liposomal bupivacaine also significantly delayed the time to first use of opioid rescue (p<0.0001) and increased the proportion of patients requiring no rescue opioid treatment (p≤0.0404) compared with placebo. The most common adverse events with liposomal bupivacaine were nausea, vomiting, and constipation. No adverse effects on the QTc interval or cardiac safety signal have been detected in the clinical trial development program (823 patients) when liposomal bupivacaine was infiltrated into the surgical site. The beneficial effects of liposomal bupivacaine on postsurgical pain management and opioid use, significantly reducing both, are likely to translate into improved clinical and economic outcomes.

Abstract
Articaine is an intermediate-potency, short-acting amide local anesthetic with a fast metabolism due to an ester group in its structure. It is effective with local infiltration or peripheral nerve block in dentistry, when administered as a spinal, epidural, ocular, or regional nerve block, or when injected intravenously for regional anesthesia. In comparative trials, its clinical effects were not generally significantly different from those of other short-acting local anesthetics like lidocaine, prilocaine, and chloroprocaine, and there is no conclusive evidence demonstrating above-average neurotoxicity. Articaine proved to be suitable and safe for procedures requiring a short duration of action in which a fast onset of anesthesia is desired, eg, dental procedures and ambulatory spinal anesthesia, in normal and in special populations.
