Propofol (di-isopropyl phenol) was synthesized by Glen and colleagues in the early 1970s, [7] but its first formulations were temporarily withdrawn due to a number of adverse reactions during clinical studies. [1] In 1983, a lipid emulsion formulation of propofol was available, which carried great potential during clinical trials. [8]
Propofol [6] is a non-barbiturate derivative that is thought to act by stimulating inhibitory GABA receptors and blocking excitatory NMDA receptors. It takes 40 seconds for the effects of propofol to kick in, and effects last six minutes. [3] Propofol has both sedative and amnestic effects, but provides no analgesia.
To induce general anesthesia, propofol is the drug used almost exclusively, having largely replaced sodium thiopental. [13]It is often administered as part of an anesthesia maintenance technique called total intravenous anesthesia, using either manually programmed infusion pumps or computer-controlled infusion pumps in a process called target controlled infusion (TCI).
Propofol can be used for total intravenous anaesthetia (TIVA), therefore supplementation by inhalation agents is not required. [45] General anesthesia is usually considered safe; however, there are reported cases of patients with distortion of taste and/or smell due to local anesthetics, stroke, nerve damage, or as a side effect of general ...
This is because remifentanil is rapidly eliminated from the blood plasma on termination of the remifentanil infusion; hence the effects of the drug quickly dissipate even after very long infusions. Owing to synergism between remifentanil and hypnotic drugs (such as propofol) the dose of the hypnotic can be substantially reduced. [16]

Patient and doctor describing state of consciousness similar to "twilight anesthesia" Twilight anesthesia is an anesthetic technique where a mild dose of sedation is applied to induce anxiolysis (anxiety relief), hypnosis, and anterograde amnesia (inability to form new memories).
But just 31 percent of the 7,745 doctors in those areas are certified to treat the legal limit of 100 patients. Even in Vermont, where the governor in 2014 signed several bills adding $6.8 million in additional funding for medication-assisted treatment programs, only 28 percent or just 60 doctors are certified at the 100-patient level.
