Depression’s New Hope: Ketamine Tablet Shows Promise in Groundbreaking Study

A new slow-release ketamine tablet, R-107, demonstrates significant antidepressant effects in treatment-resistant patients with minimal side effects, potentially revolutionizing depression treatment.

Key points:

  • The study, published in Nature Medicine, found that 57% of participants taking the highest dose of R-107 did not relapse, compared to only 29% in the placebo group.
  • R-107 is designed to be shatter-proof, addressing concerns about potential abuse as a recreational drug.
  • The tablet form could make ketamine treatment more accessible and convenient for patients with severe depression.

Researchers have unveiled a new slow-release ketamine tablet that could revolutionize the way we approach severe and treatment-resistant depression. The study, published in Nature Medicine on June 24, offers a glimmer of hope for millions who have struggled to find relief through traditional antidepressants.

Ketamine, long known as an anesthetic and, more infamously, as a party drug, has been gaining traction in recent years as a powerful tool against depression.

However, its use has been limited by the need for intravenous administration in specialized clinics and concerns about side effects. The new tablet, dubbed R-107, aims to overcome these hurdles, potentially making ketamine treatment more accessible and manageable for patients.

Led by Dr. Paul Glue, a psychiatrist at the University of Otago in New Zealand, the study involved 231 participants with major depressive disorder who had not responded to at least two previous antidepressant treatments.

The research was conducted in two phases: an initial five-day treatment period followed by a 12-week clinical trial.

The results were striking. After 13 weeks of treatment, only 43% of participants receiving the highest dose of R-107 experienced a relapse of moderate depression symptoms, compared to 71% in the placebo group.

This means that 57% of those on the highest dose maintained significant improvement in their depression, a remarkable outcome for patients who had previously found little relief.

Crucially, the study reported minimal side effects among participants. Unlike traditional ketamine administration methods, which can cause high blood pressure, elevated heart rate, and dissociative effects, R-107 was well-tolerated.

Few participants reported feelings of sedation or dissociation, and there were no significant changes in blood pressure.

“The fact that potentially you could dose this at home if you wanted to, it suddenly makes this a much easier medication to give out,” Dr. Glue explained, highlighting the tablet’s potential to dramatically expand access to ketamine treatment.

The development of R-107 also addresses a key concern surrounding ketamine’s use in depression treatment: its potential for abuse. The tablet is designed to be exceptionally hard and difficult to shatter, preventing it from being crushed and snorted — a common method of recreational use.

Dr. Rupert McShane, a psychiatrist at the University of Oxford not involved in the study, called the results promising, stating that they “certainly merit phase III investigation.”

However, he emphasized the need for further safety studies to investigate any potential for abuse or addiction.

The implications of this research extend beyond depression. Preliminary studies suggest ketamine could also be effective in treating alcohol use disorders, offering hope in an area where current medications have limited success.



“If you could somehow jumpstart their abstinence with ketamine, that would be amazing,” Dr. Glue remarked, pointing to future research directions.

While specific market projections for R-107 are not available, the potential impact on the depression treatment landscape is significant. The global depression treatment market, valued at $12.41 billion in 2022, is expected to reach $16.69 billion by 2029, according to Fortune Business Insights. A more accessible, effective treatment option like R-107 could capture a substantial portion of this growing market.

As the medical community awaits further research and potential regulatory approvals, the development of R-107 represents a promising step forward in the fight against depression. By combining the powerful antidepressant effects of ketamine with the convenience and safety of an oral tablet, this innovation could offer new hope to millions of people worldwide who continue to struggle with this debilitating condition.

For those battling treatment-resistant depression, the prospect of a more accessible, effective treatment option is nothing short of revolutionary. As research progresses, R-107 may well become a pivotal tool in the ongoing effort to improve mental health outcomes and quality of life for patients around the globe.
