All true about fospropofol except:-

Fospropofol is pro drug of propofol which is water soluble and does not cause pain on injection. Fospropofol has a slower onset and slower recovery than propofol. It is a water-soluble prodrug of propofol and is metabolized (hydrolysed) to propofol, phosphate, and formaldehyde. Fospropofol is advantageous since it is not associated with pain on injection. Due to its slower onset of sedation, it is associated with a lower incidence of hypotension, respiratory depression, apnea and loss of airway patency.
