1, different uses: sedatives are widely used in medical treatment, accounting for about 12% of the prescriptions in general hospitals, and have become the main drugs in psychiatry and neurology. Anesthetics are usually used in surgery or the treatment of certain diseases.

2. Different places of origin: 1950, Dilay and Denick produced chlorpromazine as a sedative. Leprosy powder is the earliest anesthetic invented and used in the world, which was created by Hua Tuo, an outstanding physician in the Three Kingdoms period at the end of the Eastern Han Dynasty. In the 2nd century, China had performed laparotomy under the general anesthesia of Leprosy Powder. The earliest inventor of general anesthesia in modern times was1David, an English chemist at the beginning of the 9th century.

3, different side effects: long-term use of sedatives will reduce the efficacy. It is necessary to continuously increase the dose to maintain the curative effect. Increased tolerance is always associated with addiction. Sedative hypnotics are addictive, and sudden withdrawal after long-term use will produce withdrawal symptoms. Withdrawal symptoms include anxiety, sleep disorder, anorexia, nausea, vomiting, high fever, hypotension, tremor, convulsions, disorientation and hallucinations.

The side effects of anesthetics are not as great as those of sedatives. Its disadvantage is that it can cross the placental barrier, which leads to the anesthesia of newborn puppies and inhibits the respiratory function of the respiratory system.
