“…So, changes in preparation methods and/or variations in liposomes composition have been used aiming at increasing the efficiency and encapsulation of local anesthetics [43][44][45][46] . As to local anesthetics complexation with cyclodextrins, the use of b-cyclodextrin derivatives (less toxic and more soluble) with bupivacaine has shown increased anesthetic effect added to controlled systemic drug absorption after epidural administration and intramuscular infiltration in animals, promoting a formulation with potentially effective drug-delivery system for the treatment of pain [40][41][42] . These formulations, however, still need to be submitted to local neurotoxicity studies to assure their safe clinical use.…”

“…Essa propriedade das ciclodextrinas torna bastante promissor seu uso para a complexação com anestésicos locais. Além disso, estudos indicam que a utilização de b-ciclodextrina e alguns de seus derivados (dimetil e hidroxipropil b-ciclodextrina) aumentam a solubilidade de anestésicos locaiscomo etidocaína, lidocaína, prilocaína, mepivacaína e, especialmente, bupivacaína -bem como melhoram os índices terapêuticos das drogas complexadas [38][39][40][41][42] .…”

“…However, natural -CD itself, like other CDs, is poorly soluble in water at room temperature, which is a severe limitation for its wide use in pharmaceutics [4,7,9,10] . Therefore, in order to achieve better water solubility and greater bioavailability, functional groups such as alkyl-, hydroxyalkyl-, carboxyalkyl-, amino-, glucosyl-, sulfoalkyl-, were added to the dextrin molecules chemically or enzymatically, which results in various -CD derivatives [1,5,9,[11][12][13][14][15][16][17][18][19][20][21] . Among these derivatives, sulfoalkyl ether -CDs are highly water soluble and low toxic due to the anionic nature of the substituents, and thus are thought to be of great potential in pharmaceutical applications.…”
