Commonly used anesthetics include isoflurane, ketamine, propofol, sodium pentobarbital and midazolam, according to the University of California at San Francisco. Additionally, common local anesthetics include lidocaine, mepivacaine, bupivacaine, ropivacaine and procaine, notes Drugs.com.
Newer drugs have mostly superseded the use of barbiturates as anesthetics, explains the University of California at San Francisco. Most anesthetic drugs work together in concoction with one or more types of analgesic drugs, and in many cases, an inhalant agent such as isoflurane or halothane is necessary to achieve surgical anesthesia. Opoids, such as buprenorphine and fentanyl, are among the most potent and commonly used analgesics.
