Additions and/or revisions underlined These italics usually appear at the beginning of the section. In some cases, italics may be an inherent part of the label, and will most often appear in the body of the section. |
| Underlines | Any text that is underlined indicates text that has been added or revised. There are exceptions where underlining occurs in a section subtitle or heading. This is the case when there is just one word underlined in the body of the text. |

| PCI/PI/MG | Patient Counseling Information (PLR format only) - summarizes the information that a health care provider should convey to a patient (or caregiver when applicable) when a counseling discussion is taking place (e.g., a physician prescribing a drug during an office visit, a nurse providing discharge instructions at a hospital, or a pharmacist conveying information at a pharmacy). Patient Information - FDA approved patient labeling. Medication Guide - paper handouts that come with many prescription medicines. The guides address issues that are specific to particular drugs and drug classes, and they contain FDA-approved information that can help patients avoid serious adverse events. |

SUPRANE (NDA-020118)
(DESFLURANE)
Safety-related Labeling Changes Approved by FDA Center for Drug Evaluation and Research (CDER)
11/01/2022 (SUPPL-26)
5 Warnings and Precautions
5.1 Malignant HyperthermiaAdditions and/or revisions underlined
In susceptible individuals, volatile anesthetic agents, including desflurane, may trigger malignant hyperthermia, a skeletal muscle hypermetabolic state leading to high oxygen demand. Fatal outcomes of malignant hyperthermia have been reported.
The risk of developing malignant hyperthermia increases with the concomitant administration of succinylcholine and volatile anesthetic agents. SUPRANE can induce malignant hyperthermia in patients with known or suspected susceptibility based on genetic factors or family history, including those with certain inherited ryanodine receptor (RYR1) or dihydropyridine receptor (CACNA1S) variants. [see Contraindications (4), Clinical Pharmacology (12.5)]
Signs consistent with malignant hyperthermia may include hyperthermia, hypoxia, hypercapnia, muscle rigidity (e.g., jaw muscle spasm), tachycardia (e.g., particularly that unresponsive to deepening anesthesia or analgesic medication administration), tachypnea, cyanosis, arrhythmias, hypovolemia, and hemodynamic instability. Skin mottling, coagulopathies, and renal failure may occur later in the course of the hypermetabolic process.
Successful treatment of malignant hyperthermia depends on early recognition of the clinical signs.
If malignant hyperthermia is suspected, discontinue all triggering agents (i.e., volatile anesthetic agents and succinylcholine), administer intravenous dantrolene sodium, and initiate supportive therapies. Consult prescribing information for intravenous dantrolene sodium for additional information on patient management
Supportive
therapies include administration of supplemental oxygen and respiratory support
based on clinical need, maintenance of hemodynamic stability and adequate
urinary output, management of fluid and electrolyte balance, correction of acid
base derangements, and institution of measures to control rising temperature.

5 Warnings and Precautions
5.6 Pediatric Neurotoxicity(new subsection added)
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.
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.
8 Use in Specific Populations
8.1 Pregnancy(PLLR conversion, please refer to label)
(PLLR conversion)
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when SUPRANE is administered to a nursing woman.
(additions underlined)
Respiratory Adverse Reactions in Pediatric Patients
SUPRANE is indicated for maintenance of anesthesia in infants and children after induction of anesthesia with agents other than SUPRANE, and tracheal intubation.
…
Published juvenile animal studies demonstrate that the administration of anesthetic and sedation drugs, such as SUPRANE, that either block NMDA receptors or potentiate the activity of GABA during the period of rapid brain growth or synaptogenesis, results in widespread neuronal and oligodendrocyte cell loss in the developing brain and alterations in synaptic morphology and neurogenesis. Based on comparisons across species, 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 3 years of age in humans.
In primates, exposure to 3 hours of ketamine that produced a light surgical plane of anesthesia did not increase neuronal cell loss, however, treatment regimens of 5 hours or longer of isoflurane increased neuronal cell loss. Data from isoflurane-treated rodents and ketamine-treated primates suggest that the neuronal and oligodendrocyte cell losses are associated with prolonged cognitive deficits in learning and memory. The clinical significance of these nonclinical findings is not known, and healthcare providers should balance the benefits of appropriate anesthesia in pregnant women, neonates, and young
children who require procedures with the potential risks suggested by the nonclinical data.

PATIENT COUNSELING INFORMATION(additions underlined)
…
Effect of anesthetic and sedation drugs on early brain development
Studies conducted in young animals and children suggest repeated or prolonged use of general anesthetic or sedation drugs in children younger than 3 years may have negative effects on their developing brains. Discuss with parents and caregivers the benefits, risks, and timing and duration of surgery or procedures requiring anesthetic and sedation drugs.
