To better resemble the potential effects of ketamine in unborn humans, studies have also been performed using non-human primates. Studies conducted in Rhesus macaques, a species of monkeys, have shown that ketamine use during pregnancy causes neurodegeneration in the fetal brain.
9 Another study showed Rhesus monkeys that had undergone a single administration of intravenous ketamine anesthesia during the first week of life exhibited long-lasting significant cognitive deficits.10
The Food and Drug Administration on Tuesday approved a form of ketamine, which is a rapid acting anesthetic that has been used illegally as a party drug known as "Special K," as a treatment for depression. Esketamine, developed by Johnson & Johnson and produced as a nasal spray, can only be administered in a doctor's office.
This was a single-center retrospective study of the use of ketamine for continuous sedation of mechanically ventilated patients greater than twenty-four hours between September 2011 and March 2012. These dates were chosen as they coincided with the peak shortage of traditional agents, and the greatest use of ketamine as the alternative. Ketamine was selected as the primary sedative agent, as determined by the treating physician.
The study was performed at a tertiary-care suburban community Level 1 trauma center with an annual ED census of almost 101,000 patients. The study was approved by the hospital's Institutional Review Board with a waiver of informed consent.
Ketamine is no doubt an amazing and effective treatment that has transformed people’s lives. However, inasmuch as we wish that ketamine could be for everyone, it isn’t. In this blog, we talk about certain conditions that should not be paired with ketamine.
It is also used illegally for its hallucinogenic ‘high’ effect. If bought illegally, it comes as a white powder that can be made into tablets or dissolved into a clear liquid. It can be swallowed, snorted, injected, inserted anally, or smoked with cannabis or tobacco. Sometimes it’s sold as ecstasy. It is sometimes used to spike people’s drinks.
Results:Thirty patients received ketamine for continuous sedation. In four patients, ketamine was switched to another sedative agent due to possible adverse side effects. Of these, two patients had tachydysrhythmias, both with new onset atrial fibrillation and two patients had agitation believed to be caused by ketamine. The adverse event rate in our patient population was 13% (4/30).
Robin Prothro, 60, began taking antidepressants more than 20 years ago. But she says none of the five medications she tried relieved the depression that has stymied her personal and professional life.
A decades-old drug, ketamine is already used off-label to treat depression by some doctors. At least 150 clinics around the U.S. provide treatment with various forms of the drug, which is available as a low-cost generic.
Patients often pay hundreds or thousands of dollars for intravenous infusions of the drug over several weeks or months. Such therapies are generally not covered by insurance because they haven't been approved as safe and effective by FDA regulators.
As elucidated by Delvin et al., motor activity assessment scale score is a valid and reliable sedation scale for mechanically ventilated patients in the ICU. Ketamine was able to produce adequate sedation, resulting in an average motor activity assessment score of 1.9 in our patients. Our target sedation score was between 0-2, with sedation ranging from unresponsive to responsive only to touch or name. This suggests efficacy of ketamine as a continuous agent helping to achieve appropriate sedation in mechanically ventilated patients.
We are amazed and grateful for the transformation ketamine catalyzes in people’s lives. For some, ketamine can rapidly reverse symptoms of depression or can alleviate chronic pain in a way other medications can’t. While it can do so much for some, it can be harmful to others.
It’s no surprise we love ketamine, but we equally honor the Hippocratic Oath, which includes, “Do No Harm”. In this blog, we are going to discuss the 7 types of people who should not undergo ketamine infusion treatments. As a friendly reminder, although we will be discussing several medical conditions in which ketamine should be avoided, each individual is unique and requires evaluation by a medical professional. Please be advised to see your own physician as this blog is no substitute for actual medical evaluation. Here are the 7 types of people who should NOT take ketamine:
After the VA announced in March it would offer a highly anticipated ketamine-based medication for treatment-resistant depression, a Department of Veterans Affairs panel voted last week against widespread use, instead restricting the drug for pre-approved, case-by-case treatment. The U.S. Food and Drug Administration on March 5 fast-tracked approval of Spravato, a nasal spray related to the anesthetic ketamine. Ketamine is also known in its illicit form as Special K, a party drug known for its disassociative effects, lending itself to abuse as a date rape drug. In prescription form, however, Spravato, or esketamine, has been hailed as a breakthrough treatment in a field with relatively few new options for treating unmanaged depression. VA officials lauded its arrival two weeks after Spravato received FDA approval, saying the treatment would be available to patients based on individual medical need and physicians' assessments.
But the panel that decides which medications should be included among those readily accessible to VA physicians and patients -- known as the VA's formulary -- voted last week to leave Spravato off the list. The decision means doctors will need prior approval before prescribing and buying the medication for patients. A VA spokeswoman said Monday VA psychiatrists will still be allowed to offer Spravato "when clinically indicated" but "in keeping with the FDA-approved indications for esketamine use and safety requirements." In addition, said Susan Carter, VA's director of media relations, VA has developed clinical and procedural guidance for prescribing Spravato, and "these evidence-based processes will ensure the medication is prioritized for use in veterans who have not previously responded to adequate trials of other available treatments for major depression." The decision, by the VA's Medical Advisory Panel, came two days after a joint report by The Guardian and the Center for Public Integrity that raised considerable concerns over the drug's rapid FDA approval and the VA's quick endorsement. Related: VA to Offer Ketamine-based Nasal Spray for Depression According to the report, Spravato proved no better than a placebo in two of three short-term trials. The article also charged that during the trials, six people died, including three from suicide. And it raised questions as to whether the medication is effective in males and patients ages 65 and over -- notable concerns at VA, where 90 percent of patients are men, with an average age of 63.
The media reports also charged that Johnson & Johnson, the parent company of Spravato maker Janssen, worked with the members of President Donald Trump's Mar-a-Lago club in what may have been an effort to influence the president and the VA to consider the medication. House Veterans Affairs Committee Chairman Rep. Mark Takano, D-California,
said Thursday he is alarmed that the "controversial new drug is being rushed through critical reviews and may be prescribed to veterans before fully vetting the potential risks and benefits." "Questions remain about the ultimate impact on the health and safety of veterans, who should not be made into a ‘test case’ while the clinical community continues to gather data about this treatment," Takano said. FDA officials said they fast-tracked the medicine due to the limited availability of effective antidepressants for difficult-to-treat patients. Acknowledging its extensive side effects, FDA required Spravato to carry a boxed warning for symptoms that can include sedation and blood pressure spikes and disassociation, such as feelings of physical paralysis and out-of-body experiences, and suicidal thoughts and behaviors.
The FDA also decided to make the drug available only through a restricted distribution system, administered only by a medical provider who must monitor the patient after a dose. Carter said VA will closely monitor the drug's use and effectiveness and compare it with other treatments. Based on the information received, it "may revise its clinical guidance and formulary status if warranted." In the veteran population of 20 million,
the estimated diagnosis rate of depression is 14 percent -- up to 2.8 million veterans. Between one-third to half of those veterans may be considered treatment-resistant. Takano said he has asked the VA to provide documents and information about the process for reviewing and purchasing the drug and whether VA was "pressured by the White House or the Mar-a-Lago 'three' to prescribe this drug to veterans." "Spravato should not be added to VA's formulary until we have more answers about what this means for our nation's veterans," Takano said. Veterans who remain interested in the medication should speak with their VA physicians. Eligible veterans must have tried at least two antidepressant medications and continue having symptoms of major depressive disorder. Patients also must take an additional antidepressant while being treated with Spravato. -- Patricia Kime can be reached at Patricia.Kime@Military.com. Follow her on Twitter at @patriciakime.
