Overview
11 DESCRIPTION Propofol injectable emulsion, USP is an anesthetic available as a sterile, nonpyrogenic white homogeneous emulsion for intravenous administration. The structural formula is: Chemical name: 2,6 diisopropylphenol Molecular formula: C 12 H 18 O Molecular weight: 178.27 Propofol, USP is slightly soluble in water. The pKa is 11.
Mechanism of Action
12 CLINICAL PHARMACOLOGY Propofol injectable emulsion is an intravenous general anesthetic and sedation drug for use in the induction and maintenance of anesthesia or sedation. Intravenous injection of a therapeutic dose of propofol induces anesthesia, with minimal excitation, usually within 40 seconds from the start of injection (the time for one arm-brain circulation). As with other rapidly acting intravenous anesthetic agents, the half-time of the blood-brain equilibration is approximately 1 to 3 minutes, accounting for the rate of induction of anesthesia. 12.1 Mechanism of Action The mechanism of action, like all general anesthetics, is poorly understood.

Dosage
2 DOSAGE AND ADMINISTRATION See Full Prescribing Information for detailed dosing instructions. 2.1 Important Dosage and Administration Information Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Shake well before use. Do not use if there is evidence of excessive creaming or aggregation, if large droplets are visible, or if there are other forms of phase separation indicating that the stability of the product has been compromised.
Contraindications
- 4 CONTRAINDICATIONS Propofol injectable emulsion is contraindicated in patients with a known hypersensitivity to propofol or any of propofol injectable emulsion components. Propofol injectable emulsion is contraindicated in patients with a history of anaphylaxis to eggs, egg products, soybeans or soy products. Known hypersensitivity to propofol, egg or soybean ( 4 )
Side Effects
- 6 ADVERSE REACTIONS The following serious or otherwise important adverse reactions are discussed elsewhere in the labeling: Hypersensitivity reaction [see Warnings and Precautions ( 5.1 )] Hypotension and/or bradycardia [see Warnings and Precautions ( 5.4 )] Propofol Infusion Syndrome [see Warnings and Precautions ( 5.9 )] In the description below, rates of the more common events represent US/Canadian clinical study results.
Interactions
- 7 DRUG INTERACTIONS Opioids and Sedatives The induction dose requirements of propofol injectable emulsion may be reduced in patients with intramuscular or intravenous premedication, particularly with opioids (e.g., morphine, meperidine, and fentanyl, etc.) and combinations of opioids and sedatives (e.g., benzodiazepines, barbiturates, chloral hydrate, droperidol, etc.). These agents may increase the anesthetic or sedative effects of propofol injectable emulsion and may also result in more pronounced decreases in systolic, diastolic, and mean arterial pressures and cardiac output.
