Liposomes are little spheres made from the same material as cell membranes. The medical field uses liposomes to administer medication and drugs. At the International Association for Dental Research Meeting in July, a report was released from the Institute of Biology at State University of Campinas in Brazil that says anesthesia delivered in liposomes is less painful and lasts longer than traditional means of administration. It also has a better acceptance into the body’s circulation, less toxicity, and an increased half-life, according to Dr. Giovana Tofoli. The study showed that when encapsulated mepivacaine (an anesthesia) was injected into rats, oral mucosa did not become as inflamed as it did with another traditionally administered drug that is similar to mepivacaine.
Why aren’t we using anesthesia in liposomes now? The material that the liposomes are created from is made of eggs, so it has a shelf life of six months. According to an article by Dr. Bicuspid, Dr. Tofoli is working with a firm in Brazil to find a solution to this problem.
