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.

In pediatric patients, administration of fentanyl concomitantly with propofol injectable emulsion may result in serious bradycardia. Analgesic Agents During maintenance of anesthesia or sedation, the rate of propofol injectable emulsion administration should be adjusted according to the desired level of anesthesia or sedation and may be reduced in the presence of supplemental analgesic agents (e.g., nitrous oxide or opioids).

The concurrent administration of potent inhalational agents (e.g., isoflurane, sevoflurane, desflurane, enflurane, and halothane) during maintenance with propofol injectable emulsion are routinely used. These inhalational agents can also be expected to increase the anesthetic or sedative and cardiorespiratory effects of propofol injectable emulsion. Valproate The concomitant use of valproate and propofol may lead to increased blood levels of propofol.

Reduce the dose of propofol when co-administering with valproate. Monitor patients closely for signs of increased sedation or cardiorespiratory depression. Common Neuromuscular Blocking Agents Propofol injectable emulsion does not cause a clinically significant change in onset, intensity or duration of action of the commonly used neuromuscular blocking agents (e.g., succinylcholine and nondepolarizing muscle relaxants).

Common Drugs Used as Premedication or Drugs Used During Anesthesia or Sedation No significant adverse interactions with commonly used premedications or drugs used during anesthesia or sedation (including a range of muscle relaxants, inhalational agents, analgesic agents, and local anesthetic agents) have been observed in adults. Opioids, Sedatives or Other Analgesic Agents : May increase the anesthetic/sedative and cardiorespiratory effects (7) Valproate : May lead to increased blood levels of propofol (7)

Pregnancy and breastfeeding

8.1Pregnancy Risk Summary Data

from randomized controlled trials, cohort studies and case series over several decades with propofol use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Most of the reported exposures to propofol describe propofol exposure at the time of cesarean delivery. There are reports of neonatal depression in infants exposed to propofol during delivery (see Clinical Considerations ) .

In animal reproduction studies, decreased pup survival concurrent with increased maternal mortality was observed with intravenous administration of propofol to pregnant rats either prior to mating and during early gestation or during late gestation and early lactation at exposures less than the human induction dose of 2.5 mg/kg. In pregnant rats administered 15 mg/kg/day intravenous propofol (equivalent to the human induction dose) from two weeks prior to mating to early in gestation (Gestation Day 7), offspring that were allowed to mate had increased post implantation losses.

The pharmacological activity (anesthesia) of the drug on the mother is probably responsible for the adverse effects seen in the offspring. Published studies in pregnant primates demonstrate that the administration of anesthetic and sedation drugs that block NMDA receptors and/or potentiate GABA activity during the period of peak brain development increases neuronal apoptosis in the developing brain of the offspring when used for longer than 3 hours.

There are no data on pregnancy exposures in primates corresponding to periods prior to the third trimester in humans [see Data , Warnings and Precautions (5.3) , and Use in Specific Populations (8.4) ] . The clinical significance of these nonclinical findings is not known, and the benefits of appropriate anesthesia in pregnant women who require procedures should be balanced with the potential risks suggested by the nonclinical data.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. Clinical Considerations Fetal/neonatal Adverse Reactions Propofol injectable emulsion crosses the placenta and may be associated with neonatal depression.

Monitor neonates for hypotonia and sedation following maternal exposure to propofol. Data Animal Data Pregnant rats were administered propofol intravenously at 0, 5, 10, and 15 mg/kg/day (0.3, 0.65, and 1 times the human induction dose of 2.5 mg/kg based on body surface area) during organogenesis (Gestational Days 6–15). Propofol did not cause adverse effects to the fetus at exposures up to 1 times the human induction dose despite evidence of maternal toxicity (decreased weight gain in all groups).

Pregnant rabbits were administered propofol intravenously at 0, 5, 10, and 15 mg/kg/day (0.65, 1.3, 2 times the human induction dose of 2.5 mg/kg based on body surface area comparison) during organogenesis (Gestation Days 6–18). Propofol treatment decreased total numbers of corpora lutea in all treatment groups but did not cause fetal malformations at any dose despite maternal toxicity (one maternal death from anesthesia-related respiratory depression in the high dose group).

Pregnant rats were administered propofol intravenously at 0, 10, and 15 mg/kg/day (0.65 and 1 times the human induction dose of 2.5 mg/kg based on body surface area) from late gestation through lactation (Gestation Day 16 to Lactation Day 22). Decreased pup survival was noted at all doses in the presence of maternal toxicity (deaths from anesthesia- induced respiratory depression). This study did not evaluate neurobehavioral function including learning and memory in the pups.

Pregnant rats were administered propofol intravenously at 0, 10, or 15 mg/kg/day (0.3 and 1 times the human induction dose of 2.5 mg/kg based on body surface area) from 2 weeks prior to mating to Gestational Day 7. Pup (F1) survival was decreased on Day 15 and 22 of lactation at maternally toxic doses of 10 and 15 mg/kg/day. When F1 offspring were allowed to mate, postimplantation losses were increased in the 15 mg/kg/day treatment group.

In a published study in primates, administration of an anesthetic dose of ketamine for 24 hours on Gestation Day 122 increased neuronal apoptosis in the developing brain of the fetus. In other published studies, administration of either isoflurane or propofol for 5 hours on Gestation Day 120 resulted in increased neuronal and oligodendrocyte apoptosis in the developing brain of the offspring. With respect to brain development, this time period corresponds to the third trimester of gestation in the human.

The clinical significance of these findings is not clear; however, studies in juvenile animals suggest neuroapoptosis correlates with long-term cognitive deficits [see Warnings and Precautions (5.3) , Pediatric Use (8.4) , and Animal Toxicology and/or Pharmacology (13.2) ] .

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. Less frequent events are also derived from publications and marketing experience in over 8 million patients; there are insufficient data to support an accurate estimate of their incidence rates. These studies were conducted using a variety of premedicants, varying lengths of surgical/diagnostic procedures, and various other anesthetic/sedative agents. Most adverse events were mild and transient. Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Anesthesia and MAC Sedation in Adults The following estimates of adverse events for propofol injectable emulsion include data from clinical trials in general anesthesia/MAC sedation (N=2,889 adult patients). The adverse events listed below as probably causally related are those events in which the actual incidence rate in patients treated with propofol injectable emulsion was greater than the comparator incidence rate in these trials. Therefore, incidence rates for anesthesia and MAC sedation in adults generally represent estimates of the percentage of clinical trial patients which appeared to have probable causal relationship. The adverse experience profile from reports of 150 patients in the MAC sedation clinical trials is similar to the profile established with propofol injectable emulsion during anesthesia (see Table 2 below). During MAC sedation clinical trials, significant respiratory events included cough, upper airway obstruction, apnea, hypoventilation, and dyspnea. Anesthesia in Pediatric Patients Generally, the adverse experience profile from reports of 506 propofol injectable emulsion pediatric patients from 6 days through 16 years of age in the US/Canadian anesthesia clinical trials is similar to the profile established with propofol injectable emulsion during anesthesia in adults. Although not reported as an adverse event in clinical trials, apnea is frequently observed in pediatric patients. ICU Sedation in Adults The following estimates of adverse events include data from clinical trials in ICU sedation (N=159 adult patients). Probably related incidence rates for ICU sedation were determined by individual case report form review. Probable causality was based upon an apparent dose response relationship and/or positive responses to rechallenge. In many instances the presence of concomitant disease and concomitant therapy made the causal relationship unknown. Therefore, incidence rates for ICU sedation generally represent estimates of the percentage of clinical trial patients which appeared to have a probable causal relationship. Table 2.
