Potential for abuse and strategies for containing any risks from an experimental depression treatment from Johnson & Johnson will be in focus at an Food and Drug Administration panel next week.
J&J’s nasal spray, esketamine, a close cousin of the party drug ketamine, will be considered by an FDA advisory panel on Feb. 12. While agency staff seemed satisfied that the likelihood of abuse is low, they raised questions about safety issues connected to a dreamlike sensation the medication can create in some users.
“Ketamine abuse is relatively uncommon in the general population,” agency staff said in a report ahead of next week’s meeting. Just 1.3 percent of people over age 12 abuse the drug, lower than abuse rates for other hallucinogens like ecstasy and LSD.
At the same time, reviewers worried that patients could get into accidents or otherwise be harmed if they leave a doctor’s office while still experiencing disassociation, a known side effect of ketamine — and a sought-after experience for casual users who have dubbed the spacey feeling the “K-hole.”
It takes roughly 90 minutes for disassociation symptoms from esketamine to resolve, according to the report. FDA staff also cited elevated blood pressure as a safety concern.
Esketamine is a key part of J&J’s pharmaceutical pipeline, as the company faces flagging sales this year weighed down by drug pricing scrutiny and looming generic competition. Its shares, which rose 2.3 percent this year through Thursday’s close, were were little changed in early trading on Friday.
In addition to weighing in on the drug’s safety and a proposed risk-evaluation and mitigation strategy, FDA staff will ask advisers to vote on whether esketamine effectively treated the depression of patients who weren’t helped by other therapies. They’ll also discuss whether additional studies are needed before or after the drug is potentially approved.
The staff report noted there were six deaths among patients taking the J&J drug, of which three were suicide in the esketamine depression program, but they didn’t see a clear link to the drug itself.
“Given the small number of cases, the severity of the patients’ underlying illness, and the lack of a consistent pattern among these cases, it is difficult to consider these deaths as drug related,” staff reviewers noted.
A decision on whether to allow the drug on the market is expected by March 4. Esketamine has the FDA’s breakthrough-therapy designation in treatment-resistant depression as well as for depressed people at risk of suicide. Results from a study in suicidal patients are expected this year. Allergan is also testing a fast-acting antidepressant, rapastinel, which is about a year behind esketamine in testing.

Geuris “Jerry” Rivas, a native of New York, was diagnosed with severe obsessive-compulsive disorder when he was 15. Obsessions with organizing and reorganizing the belongings in his bedroom — posters, comic books, videos — took over most of his life.
Forced by germ obsessions to compulsively wash and rewash his hands, he started wearing gloves all day to both protect him from the germs and stop him from washing his hands raw. Now, at 36, OCD symptoms continue to cost him jobs and relationships. He’s managed to turn his organizational skills into a profession — he’s a home organizer and house cleaner — but still he struggles daily with his obsessions.
“It’s caused me a great deal of suffering,” Rivas says. “I’ve tried many, many medications. I’ve wasted so much of my life.”
In 2012, running out of answers, Rivas took part in the first clinical trial to test ketamine as a treatment for OCD. While ketamine is approved by the U.S. Food and Drug Administration as an anesthetic, it is also an illicit party drug known as “Special K,” with hallucinogenic effects and the potential for abuse. Over the past 10 years, dozens of small studies of ketamine’s ability to treat a variety of mood and anxiety disorders have reported remarkable results — including the sudden alleviation of treatment-resistant depression, bipolar disorder and post-traumatic stress disorder. And these effects lasted days, sometimes weeks, after the hallucinogenic effects of the drug wore off.
With a single infusion of the drug, Rivas experienced for two weeks what it was like to live without the compulsions and obsessions that had for years controlled his life.
“I felt like, for the first time, I was able to function like a regular person,” he says.
Pros and cons
Ketamine has brought hope to a psychiatric field desperate to find new treatments for severe OCD, a chronic condition marked by debilitating obsessions and repetitive behaviors. Current treatments, which include antidepressants such as Prozac, can take months to have any effect on the disease, if they work at all.
“Severe OCD takes such a toll on patients,” says Carolyn Rodriguez, MD, PhD, who as a researcher at Columbia University ran the OCD trial. Now an assistant professor of psychiatry and behavioral sciences at Stanford, she has continued to explore the pros and cons of using ketamine to treat OCD. “The constant, intrusive thoughts that something is contaminated, the checking and rechecking, the repetitive behaviors. It interferes with your life, your jobs, your relationships.”
Ketamine was developed in the 1960s and has been used for decades as an anesthetic during surgery. It remains a mystery just how the drug works in the brain, and there are safety concerns. There is evidence from people who take the drug routinely — in much higher doses — that chronic, high-frequency ketamine use may be associated with increased risk of bladder inflammation and cognitive impairment, Rodriguez says. And if taken regularly, it can lead to dependence.
But researchers like Rodriguez are intrigued about the drug’s potential to help them identify a whole new line of medicines for fast-acting treatment of mental health disorders.
“What most excites me about ketamine is that it works in a different way than traditional antidepressants,” Rodriguez says. “Using ketamine, we hope to understand the neurobiology that could lead to safe, fast-acting treatments. I feel that is part of my mission as a physician and researcher.”
‘Right out of a movie’
Rodriguez’s interest in ketamine as a treatment for OCD was sparked about a decade ago when she was starting out as a research scientist at Columbia. A small, placebo-controlled study published in 2006 by a mentor of hers, Carlos Zarate, MD, now chief of the section on neurobiology and treatment of mood disorders at the National Institute of Mental Health, had shown that ketamine induced dramatic improvement in treatment-resistant depression within two hours of infusion. It was a landmark study, drawing attention among the psychiatric community and launching a new field of research into the use of ketamine to treat various mood and anxiety disorders.”What most excites me about ketamine is that it works in a different way than traditional antidepressants.”
Rodriguez, intent on searching for better, faster treatments for her patients like Rivas with OCD, took note. There was an emerging theory that ketamine affects the levels of the neurotransmitter glutamate in the brain and increasing evidence that glutamate plays a role in OCD symptoms, she says. Perhaps ketamine could help regulate OCD symptoms as well as depression.
In 2013, Rodriguez and colleagues published their results from that first clinical trial of ketamine in OCD patients. The trial randomized 15 patients with OCD to ketamine or placebo.
In those patients who were given ketamine, the effect was immediate. Patients reported dramatic decreases in their obsessive-compulsive symptoms midway through the 40-minute infusion, according to the study. The diminished symptoms lasted throughout the following week in half of the patients. Most striking were comments by the patients quoted in the study: “I tried to have OCD thoughts, but I couldn’t,” said one. Another said, “I feel as if the weight of OCD has been lifted.” A third said, “I don’t have any intrusive thoughts. … This is amazing, unbelievable. This is right out of a movie.” And while nearly all initially had dissociative effects like feelings of unreality, distortions of time or hallucinations, they were gone within two hours after the start of the infusion.
“Carolyn’s study was quite exciting,” Zarate says, adding that there were a number of similar, small but rigorous studies following his 2006 study that found fast-acting results using ketamine to treat bipolar disorder and post-traumatic stress disorder.
“We had no reason to believe that ketamine could wipe out any symptoms of these disorders within hours or days,” he says.
So how does it work?
Virtually all of the antidepressants used in the past 60 years work the same way: by raising levels of serotonin or one or two other neurotransmitters. Ketamine, however, doesn’t affect serotonin levels. Exactly what it does remains unclear.”There’s a recognition that people like me and others are using the drug to treat patients now. There’s an incredible need for something.”
Since coming to Stanford in 2015, Rodriguez has been funded by the National Institute of Mental Health for a large clinical trial of ketamine’s effects on OCD. This five-year trial aims to follow 90 OCD patients for as long as six months after they’ve been given a dose of ketamine or an alternative drug. Rodriguez and her research team want to observe how ketamine changes participants’ brains, as well as test for side effects.
Ultimately, Rodriguez says, she hopes the study will lead to the discovery of other fast-acting drugs that work in the brain like ketamine but without its addictive potential.
Recent research in the field indicates that the glutamate hypothesis that triggered her pilot study might be further refined.
“Ketamine is a complicated drug that works on many different receptor sites,” she says. “Researchers have fixated on the NMDA receptor, one of the glutamate-type receptors, but it might not be the only receptor bringing benefit.”
In May 2016, researchers from NIMH and the University of Maryland — Zarate among them — published a study conducted in mice showing that a chemical byproduct, or metabolite, created as the body breaks down ketamine might hold the secret to its rapid antidepressant actions. This metabolite, hydroxynorketamine, reversed depressionlike symptoms in mice without triggering any of the anesthetic, dissociative or addictive side effects associated with ketamine, Zarate says.
“Ideally, we’d like to test hydroxynorketamine and possibly other drugs that act on glutamate pathways without ketamine-like side effects as possible alternatives to ketamine in OCD,” Rodriguez says.
Beyond the clubs
Meanwhile, dozens of commercial ketamine clinics have popped up across the country, making treatments available to patients who are searching for help to stop their suffering now. Medical insurance companies usually cover ketamine’s FDA-approved use as an anesthetic but won’t cover its use for other purposes, such as mental health disorders. So patients who have run out of treatment options are paying hundreds of dollars a dose for repeated ketamine infusions.
“The fact that these clinics exist is due to the desperation of patients,” says Rodriguez.
She and other researchers are calling for guidelines to protect patients and more research to learn how to use the drug safely.
“I think it’s a game changer, and it’s here to stay,” says David Feifel, MD, PhD, professor emeritus of psychiatry at UC-San Diego, who studies the effect of ketamine on clinical depression. Feifel began prescribing the drug for patients with treatment-resistant depression in 2010.
“I’ve found it to be very safe,” Feifel says, adding that the American Psychiatric Association this year issued safety guidelines on how to use ketamine clinically for treatment of depression.
“There’s a recognition that people like me and others are using the drug to treat patients now,” he says. “There’s an incredible need for something.”
The drug hasn’t worked for everyone he’s treated, Feifel says, but for many it’s been “life-changing.”
Rodriguez says she understands what motivates the clinicians to prescribe the drug now to patients in dire straits — those who are suicidal or who have tried every possible medication and therapeutic option and continue to suffer each day.
“I see it as a way to treat people whose OCD is very, very severe,” she says. “People who can’t come out of the house, who are suicidal, who have no other options.
“I just don’t like the idea of people being in pain,” Rodriguez adds. “I want to see science translated into treatments now.”
Meanwhile, researchers are learning more about the drug. Janssen Pharmaceutical is testing the efficacy of a version of ketamine, known as esketamine, as a therapy for treatment-resistant depression and for major depressive disorder with imminent risk for suicide. The FDA has fast-tracked both investigations. At Stanford, Alan Schatzberg, MD, a professor of psychiatry and behavioral sciences, along with other faculty including Rodriguez, is studying the mechanism of action for ketamine in treating depression.
Rodriguez is also interested in using ketamine to kick-start a type of cognitive behavioral therapy called exposure and response prevention, an evidence-based psychological treatment designed to help patients overcome OCD. The therapy involves teaching patients with OCD to face anxieties by refraining from ritualizing behaviors, then progressing to more challenging anxieties as they experience success.
Relaxation and other techniques also help patients tolerate their anxiety — for example, postponing the compulsion to wash their hands for at least 30 minutes, then extending that time period.
“My goal isn’t to have people taking ketamine for long periods of time,” Rodriguez says. But perhaps a short-term course of ketamine could provide its own kind of exposure and response prevention by allowing patients to experience that it is possible not to be controlled by their OCD, she says.
Rivas well remembers that infusion of ketamine he received during Rodriguez’s first clinical trial to test the drug. The rush made him feel “like Superman.”
“I felt like my body was bigger, that I was more muscular, that I could tackle anything,” he says. But that feeling only lasted the duration of the 40-minute infusion. His OCD symptoms disappeared immediately and were still gone for two weeks after.
“I was amazed that something like that would work and work so fast,” he says. His OCD symptoms today are still intrusive, but he manages to keep them under control by taking antidepressants and seeing a therapist. Still, each day when he comes home from work, he has to put gloves on before he enters his apartment building, and as soon as he enters his apartment, he must wash his hands.
“It’s a ritual now,” he says. “There has never been a time that I haven’t done that, except those two weeks after the ketamine.”
When he heard that certain private ketamine clinics are now offering the drug as treatment for OCD, he said he understands why patients take the risks and pay the high prices. As more research has become available, he’s begun considering it himself.
“I’ve been suffering through my OCD for so long, I’ve gotten to the point where I’d try anything,” he says.

The San Francisco Veterans Affairs Medical Center is administering ketamine to veterans with post-traumatic stress disorder and depression.
Tobias Marton, the director of the ketamine infusion program at the center, said that since the program first launched two years ago, they have treated about 40 patients who had virtually exhausted all other options.
“They’ve done everything we’ve asked them to do and they remain with very severe symptoms and with a poor or impaired quality of life,” he said. “Despite (past treatments), there remains a high risk of suicide (with some veterans).”
While it was not clear where the 40 patients are from, the option is something that is available to Humboldt County veterans who are suffering from PTSD or depression.
Marton said that in general, about a third of people diagnosed with depression don’t respond to first, second and third lines of treatment.
In contrast, ketamine infusion has yielded “impressive outcomes.”
Many people know of ketamine as a party drug, often referred to as Special K, but it is mainly used medically for anesthesia or pain treatment.
Miracle of medicine
“We know ketamine has rapid and powerful anti-suicide properties,” he said. “To have another tool, a potentially powerful tool to have an impact on suicide rates is really exciting.”
While Marton is proceeding with “cautious optimism,” Boris Nikolov, the CEO of Neurosciences Medical Clinic in Miami, Florida, which has a ketamine clinic, believes the application might be a medical breakthrough.
Nikolov’s clinic has treated 120 patients with ketamine, including his wife who has PTSD as a result of severe child abuse.
“Ketamine really helped her,” he said. “That was a really big part of her recovery.”
Nikolov said most medicines that treat depression take from two to four weeks to start working. Ketamine begins working within hours after it is administered, a process which usually involves an IV infusion over the course of about an hour.
“What’s most important is the strong and fast effect of ketamine in patients who are very seriously depressed, or want to hurt themselves,” he said. “When they finish treatment, they’re totally different people. There is no other medication that does that.”
Brad Burge, the director of strategic communication at the Multidisciplinary Association for Psychedelic Studies, or MAPS, said there has been “an explosion of treatment that’s outpaced research.”
“It means that people are going to have another option, an alternative to conventional medications,” he said.
According to Burge, MAPS believes the best form of ketamine infusion involves pairing with other forms of psychotherapy such as group or individual counseling.
While ketamine is an FDA-approved drug which has been used as an anesthetic as well as a pain reliever, it isn’t officially sanctioned by the FDA to be used for treating mental health disorders. However, Marton said that ketamine has been administered in this fashion for over 18 years now.
A company is currently in the process of trying to get an intranasal product approved by the FDA which would administer ketamine through the nasal passage, according to Marton. He expects the FDA’s decision to be announced sometime around March 2019.
If the product is approved, he said, VA clinics in rural communities like the one in Eureka would likely be able to start offering ketamine treatments as well.
For now, only the location in San Francisco is able to offer the treatment, but Marton said anyone within their service realm, which includes Humboldt County, is invited to consult with the VA about seeking treatment.
“We want to be as thoughtful as we can,” he said. “As we understand more about it … (we) might be able to start helping people who we haven’t been able to help despite throwing everything we have at them.”

New Drug Combo Shows Promise for Treatment of Depression and Addiction
The combination of naltrexone and ketamine can help treat both symptoms of addiction and depression, a preliminary study by Yale University researchers suggests.
Substance abuse and depression are common in many patients, and efforts to treat both conditions simultaneously have had limited success. One recent study suggested that the antidepressant effects of ketamine might blunted by administration of naltrexone, used to limit cravings of those addicted to opioid drugs and alcohol.
A preliminary study of five patients suffering from both depression and substance abuse disorders suggest that isn’t the case. The study was published Jan. 9 in the journal JAMA Psychiatry.
The results “raise the possibility that for people who have depression complicated by substance abuse disorders, the combination of ketamine and naltrexone may be a strategy to explore in the effort to optimally treat both conditions,” said senior author John Krystal, Yale’s Robert L. McNeil Jr. Professor of Translational Research; professor of psychiatry, neuroscience, and psychology; and chair of the Department of Psychiatry.
Krystal and lead author Gihyun Yoon, assistant professor of psychiatry, treated the five patients suffering from depression and alcohol use disorder with a long-lasting form of naltrexone and then administered ketamine. Four of the five responded to the first ketamine dose and all five found relief from depression after multiple doses.
The study also challenges the idea that ketamine might produce antidepressant effects by stimulating opiate receptors.
Krystal cautioned that larger studies are needed to confirm beneficial effects of the combination treatment.
Krystal and Yoon have provisional patents on the use of ketamine and naltrexone to treat comorbid depression and substance abuse.
The study was primarily funded by the U.S. Department of Veterans Affairs.

http://bpsreno.com/?search=best-way-to-use-levitra There is an urgent need for better medications that work quickly for treatment of major depression and bipolar disorder. The treatment should also be tolerable and work for depressed patients who have not responded to conventional treatments, ie, who have treatment-resistant depression (TRD).
order cialis without prescription Ketamine is a medication that is used intravenously for anesthesia, but multiple controlled trials have now demonstrated a rapid antidepressant response to a single intravenous infusion of ketamine. Controlled studies of regular infusions appear promising, but the need for regular IV infusions is not something that is appealing to most patients and often results in non-compliance. And, oral ketamine is extensive broken down by the liver before it can be absorbed by the body, so oral therapy is not a viable option. Therefore, the intranasal route has been investigated.
first female drug like viagra Intranasal drug delivery offers a route to the brain that bypasses problems related to gastrointestinal absorption, first-pass metabolism, and the blood-brain barrier; and the onset of therapeutic action is rapid. Intranasal medications avoid the inconvenience and discomfort of IV therapy. Intranasal medications have been used to treat migraine, acute and chronic pain, Parkinson’s disease, cognitive disorders, autism, schizophrenia, social phobia, and depression.
go to site In a randomized, double-blind, placebo-controlled, crossover trial conducted in 20 patients with major depression, physicians and researchers at the Icahn School of Medicine at Mount Sinai, New York, tested the safety, tolerability, and efficacy of intranasal ketamine in patients with depression who had failed at least one prior antidepressant trial. The researchers found that a single intranasal dose of ketamine (50 mg) outperformed placebo; the response rate was 44% versus 6%, respectively. Anxiety ratings also decreased significantly more with ketamine. Patients showed significant improvement in depressive symptoms at 24 hours after ketamine compared to placebo. Intranasal ketamine was well tolerated with minimal psychotomimetic or dissociative effects and was not associated with clinically significant changes in hemodynamic parameters like blood pressure.
http://patriciathayer.com/?search=get-cialis Intranasal ketamine represents a promising advance in treatment-resistant depression (TRD) therapeutics. Most studies report a duration of response up to 7 days and remission up to 3-5 days after a single dose. “Most adverse events … subsided spontaneously by 60 to 90 minutes post dose,” said Vanina Popova, MD. In addition, “there was no pushback” to the nasal delivery system. “The route of administration was well received, and it was certainly more convenient than intravenous administration,” she said.
Intranasal ketamine is not commercially available, but the clinical use of intranasal ketamine is increasing internationally. Research has concluded that the drug formulation, the delivery device, the technique and individual patient factors play an important role in tolerability and efficacy when using intranasal ketamine for Treatment Resistant Depression.
Intranasal ketamine has been reported in studies to help depressed patients who have not responded to conventional therapy with minimal side effects. Ask our pharmacist for more information about compounded intranasal ketamine. We customize medications to meet each patient’s specific needs.

Ketamine 25mg – 100 mg Nasal Spray
BACKGROUND: The N-methyl-D-aspartate glutamate receptor antagonist ketamine, delivered via an intravenous route, has shown rapid antidepressant effects in patients with treatment-resistant depression. The current study was designed to test the safety, tolerability, and efficacy of intranasal ketamine in patients with depression who had failed at least one prior antidepressant trial. METHODS: In a randomized, double-blind, crossover study, 20 patients with major depression were randomly assigned, and 18 completed 2 treatment days with intranasal ketamine hydrochloride (50 mg) or saline solution. The primary efficacy outcome measure was change in depression severity 24 hours after ketamine or placebo, measured using the Montgomery-Åsberg Depression Rating Scale. Secondary outcomes included persistence of benefit, changes in self-reports of depression, changes in anxiety, and proportion of responders. Potential psychotomimetic, dissociative, hemodynamic, and general adverse effects associated with ketamine were also measured. RESULTS: Patients showed significant improvement in depressive symptoms at 24 hours after ketamine compared to placebo (t = 4.39, p < .001; estimated mean Montgomery-Åsberg Depression Rating Scale score difference of 7.6 ± 3.7; 95% confidence interval, 3.9-11.3). Response criteria were met by 8 of 18 patients (44%) 24 hours after ketamine administration compared with 1 of 18 (6%) after placebo (p = .033). Intranasal ketamine was well tolerated with minimal psychotomimetic or dissociative effects and was not associated with clinically significant changes in hemodynamic parameters. CONCLUSIONS: This study provides the first controlled evidence for the rapid antidepressant effects of intranasal ketamine. Treatment was associated with minimal adverse effects. If replicated, these findings may lead to novel approaches to the pharmacologic treatment of patients with major depression
