  • Propofol microdroplet formulations
    Patent number: 5637625
    Abstract: Formulations of phospholipid-coated microdroplets of propofol devoid of fats and triglycerides provide chronic sedation over extended periods of time without fat overload. Being free of nutrients that support bacterial growth, these microdroplet formulations are bacteriosatic and bactericidal (e.g. self-sterilizing) and thus have extended shelf life.
