Intravenous general anaesthetics at least seem to work by enhancing the effects of GABA or blocking the effects of glutamate. The protein theory is currently considered more likely to explain the process of anaesthesia, because general anaesthetics affect synaptic transmission rather than axonal conduction. Both the release of transmitter and the response of the postsynaptic receptors are affected.

General anaesthesia aims to achieve loss of consciousness in the patient together with loss of all sensation. Usually this is to allow surgery or manipulation of a body part. Local anaesthesia is the loss of sensation in a particular part of the body while the patient remains conscious. This can allow minor surgery or valacyclovir 500 mg price treatment of a body part.
