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. Slight creaming, which should disappear after shaking, may be visible upon prolonged standing. Do not use if there is evidence of separation of the phases of the emulsion. Propofol injectable emulsion with EDTA inhibits microbial growth for up to 12 hours, as demonstrated by test data for representative USP microorganisms. Product is packaged under nitrogen. For general anesthesia or monitored anesthesia care (MAC) sedation, propofol injectable emulsion should be administered only by persons trained in the administration of general anesthesia and not involved in the conduct of the surgical/diagnostic procedure. Sedated patients should be continuously monitored, and equipment for maintaining a patent airway, providing artificial ventilation, administering supplemental oxygen, and instituting cardiovascular resuscitation must be immediately available. Patients should be continuously monitored for early signs of hypotension, apnea, airway obstruction, and/or oxygen desaturation. These cardiorespiratory effects are more likely to occur following rapid bolus administration, especially in the elderly, debilitated, or ASA-PS III or IV patients. For sedation of intubated, mechanically ventilated adult patients in the Intensive Care Unit, propofol injectable emulsion should be administered only by persons skilled in the management of critically ill patients and trained in cardiovascular resuscitation and airway management. Guidelines for Aseptic Technique for General Anesthesia/MAC Sedation Propofol injectable emulsion must be prepared for use just prior to initiation of each individual anesthetic/sedative procedure. The vial rubber stopper should be disinfected using 70% isopropyl alcohol. Propofol injectable emulsion should be drawn into a sterile syringe immediately after a vial is opened. When withdrawing propofol injectable emulsion from vials, a sterile vent spike should be used. The syringe should be labelled with appropriate information including the date and time the vial was opened. Administration should commence promptly and be completed within 12 hours after the vial has been opened. Propofol injectable emulsion must be prepared for single dose only. Any unused propofol injectable emulsion drug product, reservoirs, dedicated administration tubing and/or solutions containing propofol injectable emulsion must be discarded at the end of the anesthetic procedure or at 12 hours, whichever occurs sooner. The intravenous line should be flushed every 12 hours and at the end of the anesthetic procedure to remove residual propofol injectable emulsion. [see Warnings and Precautions ( 5.2 )] . Guidelines for Aseptic Technique for ICU Sedation Propofol injectable emulsion must be prepared for single dose only. Strict aseptic techniques must be followed. The vial rubber stopper should be disinfected using 70% isopropyl alcohol. A sterile vent spike and sterile tubing must be used for administration of propofol injectable emulsion. As with other lipid emulsions, the number of intravenous line manipulations should be minimized. Administration should commence promptly and must be completed within 12 hours after the vial has been spiked. The tubing and any unused propofol injectable emulsion drug product must be discarded after 12 hours. If propofol injectable emulsion is transferred to a syringe prior to administration, it should be drawn into a sterile syringe immediately after a vial is opened. When withdrawing propofol injectable emulsion from a vial, a sterile vent spike should be used. The syringe should be labelled with appropriate information including the date and time the vial was opened. Administration should commence promptly and be completed within 12 hours after the vial has been opened. Propofol injectable emulsion should be discarded and administration lines changed after 12 hours. [see Warnings and Precautions ( 5.2 )] Administration with Lidocaine If lidocaine is to be administered to minimize pain on injection of propofol injectable emulsion, it is recommended that it be administered prior to propofol injectable emulsion administration or that it be added to propofol injectable emulsion immediately before administration and in quantities not exceeding 20 mg lidocaine/200 mg propofol injectable emulsion. [see Warnings and Precautions ( 5.13 )] Compatibility and Stability Propofol injectable emulsion should not be mixed with other therapeutic agents prior to administration. Dilution Prior to Administration Propofol injectable emulsion is provided as a ready-to-use formulation. However, should dilution be necessary, it should only be diluted with 5% Dextrose Injection, USP, and it should not be diluted to a concentration less than 2 mg/mL because it is an emulsion. In diluted form it has been shown to be more stable when in contact with glass than with plastic (95% potency after 2 hours of running infusion in plastic). Administration with Other Fluids Compatibility of propofol injectable emulsion with the coadministration of blood/serum/plasma has not been established [see Warnings and Precautions ( 5.15 )] . When administered using a y-type infusion set, propofol injectable emulsion has been shown to be compatible with the following intravenous fluids: 5% Dextrose Injection, USP Lactated Ringers Injection, USP Lactated Ringers and 5% Dextrose Injection 5% Dextrose and 0.45% Sodium Chloride Injection, USP 5% Dextrose and 0.2% Sodium Chloride Injection, USP. Administration with Pumps When administering propofol injectable emulsion by infusion, syringe or volumetric pumps are recommended to provide controlled infusion rates. When infusing propofol injectable emulsion to patients undergoing magnetic resonance imaging, metered control devices may be utilized if mechanical pumps are impractical. Administration with Filters Clinical experience with the use of in-line filters and propofol injectable emulsion during anesthesia or ICU/MAC sedation is limited. Propofol injectable emulsion should only be administered through a filter with a pore size of 5 micron or greater unless it has been demonstrated that the filter does not restrict the flow of propofol injectable emulsion and/or cause the breakdown of the emulsion. Filters should be used with caution and where clinically appropriate. Continuous monitoring is necessary due to the potential for restricted flow and/or breakdown of the emulsion. 2.2 Induction of General Anesthesia for Patients Greater than or Equal to 3 Years of Age Adult Patients Most adult patients under 65 years of age and classified as ASA-PS I or II require 2 mg/kg to 2.5 mg/kg of propofol injectable emulsion. For induction, whether administered by infusion or intravenous injection the dose of propofol injectable emulsion to the patient should be titrated against the response of the patient and until there are clinical signs consistent with the onset of anesthesia. As with other sedative-hypnotic agents, the amount of intravenous opioid and/or benzodiazepine premedication may impact the dose of propofol injectable emulsion required for induction of general anesthesia. Elderly, Debilitated, or ASA-PS III or IV Patients Due to the reduced clearance and higher blood concentrations, most elderly, debilitated, or ASA-PS III or IV patients require approximately 1 mg/kg to 1.5 mg/kg of propofol injectable emulsion for induction of anesthesia. For induction, whether administered by infusion or intravenous inje

WARNINGS AND PRECAUTIONS Hypersensitivity Reactions : Serious and sometimes fatal reactions ( 5.1 ) Microbial Contamination : Strict aseptic technique must be maintained during handling. Propofol injectable emulsion vials are never to be accessed more than once or used on more than one person. Administration should commence promptly and be completed within 12 hours after the vial has been opened. Discard unused drug product. Do not use if contamination is suspected ( 5.2 ) Cardiovascular depression : Cases of bradycardia, asystole, and cardiac arrest have been reported. Pediatric patients are susceptible to this effect, particularly when fentanyl is given concomitantly ( 5.4 ) 5.1 Anaphylactic and Anaphylactoid Reactions Use of propofol injectable emulsion has been associated with both fatal and life threatening anaphylactic and anaphylactoid reactions. Clinical features of anaphylaxis, including angioedema, bronchospasm, erythema, and hypotension, occur rarely following propofol injectable emulsion administration. 5.2 Risks of Microbial Contamination Strict aseptic technique must always be maintained during handling. Propofol injectable emulsion is a single-dose parenteral product (single patient infusion vial) which contains 0.005% disodium edetate (EDTA) to inhibit the rate of growth of microorganisms, for up to 12 hours, in the event of accidental extrinsic contamination. However, propofol injectable emulsion can still support the growth of microorganisms, as it is not an antimicrobially preserved product under USP standards. Do not use if contamination is suspected. Discard unused drug product as directed within the required time limits. There have been reports in which failure to use aseptic technique when handling propofol injectable emulsion was associated with microbial contamination of the product and with fever, infection/sepsis, other life-threatening illness, and/or death. Propofol injectable emulsion vials are never to be accessed more than once or used on more than one person. There have been reports, in the literature and other public sources, of the transmission of bloodborne pathogens (such as Hepatitis B, Hepatitis C, and HIV) from unsafe injection practices, and of the use of propofol vials intended for single use on multiple persons. 5.3 Risks of Pediatric Neurotoxicity Published animal studies demonstrate that the administration of anesthetic and sedation drugs that block NMDA receptors and/or potentiate GABA activity increase neuronal apoptosis in the developing brain and result in long-term cognitive deficits when used for longer than 3 hours. The clinical significance of these findings is not clear. However, based on the available data, the window of vulnerability to these changes is believed to correlate with exposures in the third trimester of gestation through the first several months of life, but may extend out to approximately three years of age in humans [see Animal Toxicology and/or Pharmacology ( 13.2 )]. Some published studies in children suggest that similar deficits may occur after repeated or prolonged exposures to anesthetic agents early in life and may result in adverse cognitive or behavioral effects. These studies have substantial limitations, and it is not clear if the observed effects are due to the anesthetic/sedation drug administration or other factors such as the surgery or underlying illness. Anesthetic and sedation drugs are a necessary part of the care of children needing surgery, other procedures, or tests that cannot be delayed, and no specific medications have been shown to be safer than any other. Decisions regarding the timing of any elective procedures requiring anesthesia should take into consideration the benefits of the procedure weighed against the potential risks. 5.4 Risks of Bradycardia, Asystole, and Cardiac Arrest Propofol injectable emulsion has no vagolytic activity. Reports of bradycardia, asystole, and rarely, cardiac arrest have been associated with propofol injectable emulsion. Pediatric patients are susceptible to this effect, particularly when fentanyl is given concomitantly. The intravenous administration of anticholinergic agents (e.g., atropine or glycopyrrolate) should be considered to modify potential increases in vagal tone due to concomitant agents (e.g., succinylcholine) or surgical stimuli. 5.5 Risk of Seizures When propofol injectable emulsion is administered to an epileptic patient, there is a risk of seizure during the recovery phase. 5.6 Neurosurgical Anesthesia When propofol injectable emulsion is used in patients with increased intracranial pressure or impaired cerebral circulation, significant decreases in mean arterial pressure should be avoided because of the resultant decreases in cerebral perfusion pressure. To avoid significant hypotension and decreases in cerebral perfusion pressure, an infusion or slow bolus should be utilized instead of rapid, more frequent, and/or larger boluses of propofol injectable emulsion. Slower induction, titrated to clinical responses, will generally result in reduced induction dosage requirements (1 mg/kg to 2 mg/kg). When increased ICP is suspected, hyperventilation and hypocarbia should accompany the administration of propofol injectable emulsion [see Dosage and Administration ( 2.1 )] . 5.7 Cardiac Anesthesia Slower rates of administration should be utilized in premedicated patients, geriatric patients, patients with recent fluid shifts, and patients who are hemodynamically unstable. Fluid deficits should be corrected prior to administration of propofol injectable emulsion. In those patients where additional fluid therapy may be contraindicated, other measures, e.g., elevation of lower extremities, or use of pressor agents, may be useful to offset the hypotension which is associated with the induction of anesthesia with propofol injectable emulsion. 5.8 Use for Intensive Care Unit Sedation of Intubated, Mechanically Ventilated Adult Patients The administration of propofol injectable emulsion should be initiated as a continuous infusion and changes in the rate of administration made slowly (>5 min) in order to minimize hypotension and avoid acute overdosage [see Overdosage ( 10 ) and Dosage and Administration ( 2.5 )] . Patients should be monitored for early signs of significant hypotension and/or cardiovascular depression, which may be profound. These effects are responsive to discontinuation of propofol injectable emulsion, intravenous fluid administration, and/or vasopressor therapy. In the elderly, debilitated, or ASA-PS III or IV patients, rapid (single or repeated) bolus administration should not be used during sedation in order to minimize undesirable cardiorespiratory depression. As with other sedative medications, there is wide interpatient variability in propofol injectable emulsion dosage requirements, and these requirements may change with time. Failure to reduce the infusion rate in patients receiving propofol injectable emulsion for extended periods may result in excessively high blood concentrations of the drug. Thus, titration to clinical response and daily evaluation of sedation levels are important during use of propofol injectable emulsion infusion for ICU sedation, especially when it is used for long durations. Opioids and paralytic agents should be discontinued and respiratory function optimized prior to weaning patients from mechanical ventilation. Infusions of propofol injectable emulsion should be adjusted to maintain a light level of sedation prior to weaning patients from mechanical ventilatory support. Throughout the weaning process, this level of sedation may be maintained in the absence of respiratory depression. Abrupt discontinuation of propofol injectable emulsion prior to weaning or for daily evaluation of sedation levels should be avoided. This may result in rapid awakening with associated anxiety, agitation, and resistance to mechanical ventilation. It is therefore recommended that administ

CLINICAL PHARMACOLOGY: General DIPRIVAN 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 minute to 3 minutes, accounting for the rate of induction of anesthesia. The mechanism of action, like all general anesthetics, is poorly understood. However, propofol is thought to produce its sedative/anesthetic effects by the positive modulation of the inhibitory function of the neurotransmitter GABA through the ligand-gated GABA A receptors. Pharmacodynamics Pharmacodynamic properties of propofol are dependent upon the therapeutic blood propofol concentrations. Steady-state propofol blood concentrations are generally proportional to infusion rates. Undesirable side effects, such as cardiorespiratory depression, are likely to occur at higher blood concentrations which result from bolus dosing or rapid increases in infusion rates. An adequate interval (3 minutes to 5 minutes) must be allowed between dose adjustments in order to assess clinical effects. The hemodynamic effects of DIPRIVAN during induction of anesthesia vary. If spontaneous ventilation is maintained, the major cardiovascular effect is arterial hypotension (sometimes greater than a 30% decrease) with little or no change in heart rate and no appreciable decrease in cardiac output. If ventilation is assisted or controlled (positive pressure ventilation), there is an increase in the incidence and the degree of depression of cardiac output. Addition of an opioid, used as a premedicant, further decreases cardiac output and respiratory drive. If anesthesia is continued by infusion of DIPRIVAN, the stimulation of endotracheal intubation and surgery may return arterial pressure towards normal. However, cardiac output may remain depressed. Comparative clinical studies have shown that the hemodynamic effects of DIPRIVAN during induction of anesthesia are generally more pronounced than with other intravenous (IV) induction agents. Induction of anesthesia with DIPRIVAN is frequently associated with apnea in both adults and pediatric patients. In adult patients who received DIPRIVAN (2 mg/kg to 2.5 mg/kg), apnea lasted less than 30 seconds in 7% of patients, 30 seconds to 60 seconds in 24% of patients, and more than 60 seconds in 12% of patients. In pediatric patients from birth through 16 years of age assessable for apnea who received bolus doses of DIPRIVAN (1 mg/kg to 3.6 mg/kg), apnea lasted less than 30 seconds in 12% of patients, 30 seconds to 60 seconds in 10% of patients, and more than 60 seconds in 5% of patients. During maintenance of general anesthesia, DIPRIVAN causes a decrease in spontaneous minute ventilation usually associated with an increase in carbon dioxide tension which may be marked depending upon the rate of administration and concurrent use of other medications (e.g., opioids, sedatives, etc.). During monitored anesthesia care (MAC) sedation, attention must be given to the cardiorespiratory effects of DIPRIVAN. Hypotension, oxyhemoglobin desaturation, apnea, and airway obstruction can occur, especially following a rapid bolus of DIPRIVAN. During initiation of MAC sedation, slow infusion or slow injection techniques are preferable over rapid bolus administration. During maintenance of MAC sedation, a variable rate infusion is preferable over intermittent bolus administration in order to minimize undesirable cardiorespiratory effects. In the elderly, debilitated, or American Society of Anesthesiologists Physical Status (ASA-PS) III or IV patients, rapid (single or repeated) bolus dose administration should not be used for MAC sedation (see WARNINGS ). Clinical and preclinical studies suggest that DIPRIVAN is rarely associated with elevation of plasma histamine levels. Preliminary findings in patients with normal intraocular pressure indicate that DIPRIVAN produces a decrease in intraocular pressure which may be associated with a concomitant decrease in systemic vascular resistance. Clinical studies indicate that DIPRIVAN when used in combination with hypocarbia increases cerebrovascular resistance and decreases cerebral blood flow, cerebral metabolic oxygen consumption, and intracranial pressure. DIPRIVAN does not affect cerebrovascular reactivity to changes in arterial carbon dioxide tension (see Clinical Trials, Neuroanesthesia ). Clinical studies indicate that DIPRIVAN does not suppress the adrenal response to ACTH. Animal studies and limited experience in susceptible patients have not indicated any propensity of DIPRIVAN to induce malignant hyperthermia. Hemosiderin deposits have been observed in the livers of dogs receiving DIPRIVAN containing 0.005% disodium edetate over a four-week period; the clinical significance of this is unknown. Pharmacokinetics The pharmacokinetics of propofol are well described by a three compartment linear model with compartments representing the plasma, rapidly equilibrating tissues, and slowly equilibrating tissues. Following an IV bolus dose, there is rapid equilibration between the plasma and the brain, accounting for the rapid onset of anesthesia. Plasma levels initially decline rapidly as a result of both distribution and metabolic clearance. Distribution accounts for about half of this decline following a bolus of propofol. However, distribution is not constant over time, but decreases as body tissues equilibrate with plasma and become saturated. The rate at which equilibration occurs is a function of the rate and duration of the infusion. When equilibration occurs there is no longer a net transfer of propofol between tissues and plasma. Discontinuation of the recommended doses of DIPRIVAN after the maintenance of anesthesia for approximately one hour, or for sedation in the ICU for one day, results in a prompt decrease in blood propofol concentrations and rapid awakening. Longer infusions (10 days of ICU sedation) result in accumulation of significant tissue stores of propofol, such that the reduction in circulating propofol is slowed and the time to awakening is increased. By daily titration of DIPRIVAN dosage to achieve only the minimum effective therapeutic concentration, rapid awakening within 10 minutes to 15 minutes can occur even after long-term administration. If, however, higher than necessary infusion levels have been maintained for a long time, propofol redistribution from fat and muscle to the plasma can be significant and slow recovery. The figure below illustrates the fall of plasma propofol levels following infusions of various durations to provide ICU sedation. The large contribution of distribution (about 50%) to the fall of propofol plasma levels following brief infusions means that after very long infusions a reduction in the infusion rate is appropriate by as much as half the initial infusion rate in order to maintain a constant plasma level. Therefore, failure to reduce the infusion rate in patients receiving DIPRIVAN for extended periods may result in excessively high blood concentrations of the drug. Thus, titration to clinical response and daily evaluation of sedation levels are important during use of DIPRIVAN infusion for ICU sedation. Adults Propofol clearance ranges from 23 mL/kg/min to 50 mL/kg/min (1.6 L/min to 3.4 L/min in 70 kg adults). It is chiefly eliminated by hepatic conjugation to inactive metabolites which are excreted by the kidney. A glucuronide conjugate accounts for about 50% of the administered dose. Propofol has a steady-state volume of distribution (10-day infusion) approaching 60 L/kg in healthy adults. A difference in pharmacokinetics due to sex has not been observed. The terminal half-life of propofol after a
