What are 'barbiturates'?
The barbiturates are classified as sedative-hypnotic drugs, and in the past were used for induction of anaesthesia. The barbiturates of the past were great for inducing anaesthesia, but they did not have analgesic, or pain-protective properties. The old barbiturates of Secobarbitol, Pentothal, Gravital, have been supplanted by a new medication called Propofol which has the same properties as barbiturates, but does also have analgesic properties. That is now the major medication that is used to induce anaesthesia.
