A changing landscape
Five years later, these barriers remain. However, advocates note support for a registry is growing, due in large part to a series of developments over the past 6 years that they believe have altered the ketamine landscape.
Chief among these was the 2019 FDA approval of esketamine, a nasal formulation of ketamine, for the treatment of resistant depression. The drug’s indication was expanded in 2020 to include major depressive disorder and acute suicidal ideation or behavior. The drug is only available through a restricted distribution system – the Spravato Risk Evaluation and Mitigation Strategy (REMS) – because of the risk for serious adverse events, including sedation and dissociation, as well as the potential for abuse or misuse.
A sharp increase in the number of ketamine prescribers and clinics has also heightened interest in a ketamine registry. In the last year alone, membership in the American Society of Ketamine Physicians, Psychotherapists, and Practitioners (ASKP) – a nonprofit trade organization for clinicians who prescribe ketamine for mental health disorders and pain conditions – swelled from 300 individual providers to more than 500.
The number of ketamine clinics in the United States has also grown exponentially and is estimated to be anywhere from 500 to 750. A spokesperson with HHS said such clinics are not regulated by the department or any other federal agency but instead are subject to oversight by individual states.
Although recreational use of ketamine remains low overall, there are signs that illicit use is rising, including an increase in DEA seizures of illicit ketamine and reports of ketamine-related poisonings to the nation’s poison control centers. Data on recreational use is spotty, at best. The Centers for Disease Control and Prevention National Vital Statistics System – the primary source of information on drug-related mortality in the United States – does not report on ketamine.
At-home ketamine use soars
Perhaps the most significant development came in March 2020 in the early days of the pandemic. To ease access to therapeutic schedule II-V controlled substances, the DEA issued a waiver that relaxed restrictions in the Ryan Haight Act, legislation that requires that patients be seen at least once in person before receiving a prescription for this class of drugs.
Under the waiver, DEA-registered practitioners are allowed to prescribe these substances – including ketamine, a schedule III substance – via telemedicine, without an in-person exam.
Startup companies cropped up almost overnight to prescribe oral ketamine online for at-home use, with almost no oversight. A spokesperson with the DEA told this news organization that the agency is working to make these “temporary” regulations permanent.
Under the relaxed DEA guidelines, a prescriber only needs to have a DEA license to dispense a ketamine prescription. An alarming number of clinics and online startups are staffed by individuals with no training in ketamine use and, in some cases, no formal mental health training at all, said Lisa Harding, MD, vice president of ASKP and a clinical instructor of psychiatry at Yale School of Medicine.
“The biggest problem is not the ketamine itself, it’s that the majority of practitioners are not psychiatrists, so they don’t have mental health training,” Dr. Harding said. “The fact that an untrained person, any practitioner with no mental health training, can administer this treatment once they have a state license to give ketamine ... then how are you protecting the patients?”
That question prompted ASKP to create the first known program to train psychiatrists, and other qualified mental health practitioners who prescribe ketamine, how to use the drug safely and effectively. The program, scheduled for June, will also include discussion by leaders in the field about how a ketamine registry might address these and other patient safety concerns.
“Nobody is really investigating the standard to which these clinics and online companies should be held, and I think a registry would help with that,” she said in an interview.
