<p>Propofol has been used in association with spinal and epidural anaesthesia as well as with various types of premedicants, muscle relaxants, inhalation anaesthetics and analgetics. No pharmacological incompatibility has been observed. Lower doses of Propofol may be sufficient in case Propofol is used as an adjunct to local anaesthetic techniques. In doses applied clinically, propofol will not inhibit the synthesis of adrenocortical hormones. Simultaneous administration of opiates may potentiate respiratory depression caused by Propofol.</p>
