About Esketamine Treatment

What is Esketamine (Spravato)?

In 2020 Medical and Healthcare Products Regulatory Agency (MHRA) in the UK approved Esketamine (Spravato®) as a medication that can be used in the treatment of patients who suffer from moderate to severe treatment-resistant depression.

SPRAVATO® is the brand name of an Esketamine nasal spray, which is now available at Pasithea Clinics. Esketamine is a Schedule III controlled substance (CIII) and is used, in conjunction with an oral antidepressant, to treat adults with treatment-resistant depression. 

The decision to prescribe Esketamine is determined by a clinical psychiatrist, and patients wishing to access this treatment must be under the care of a Pasithea clinics physician, for the duration of treatment.

As a result of Esketamine (Spravato®) being MHRA-approved, insurance companies are beginning to cover this treatment.

About Esketamine Treatment

How does Esketamine treatment work?

Esketamine, like Ketamine, has the potential to distort your perception during the first two hours after treatment, so it must be administered in a clinic setting. This is done on an outpatient basis.Treatment is self-administered and you will be taught by our specialist nurse how to self-administer the nasal spray to achieve the best results.

With the nasal spray, you give yourself three doses, spaced five minutes apart, under doctor supervision. You remain in the clinic under doctor observation until potential side effects have passed.

Esketamine must be used in conjunction with a conventional antidepressant. There are two different types of anti-depressant which Esketamine can be used with: SSRIs and SNRIs. Common examples of these type of drugs include Sertraline and Duloxetine. The intention is that Esketamine provides rapid relief from depression symptoms until the other medication takes effect. This is one of the reasons it is known as a fast-acting anti-depressant.

About Esketamine Treatment

How does Esketamine
treat depression?

Esketamine, and its related drug, Ketamine, are highly effective depression treatments for a number of reasons:

Esketamine’s antidepressant function works through a different mechanism than other drugs. Conventional antidepressants work by increasing levels of naturally occurring chemicals such as serotonin, norepinephrine and dopamine. These chemicals are messengers that relay communication between brain cells. The theory is that having greater quantities of these neurotransmitters allows for better communication between brain cells and positively affects mood.

Esketamine works in a similar fashion, but unlike other antidepressants its mechanism of action increases levels of glutamate, the most abundant chemical messenger in the brain. The result? A greater impact on more brain cells at one time.

Up to 33% of people with depression don’t respond to multiple kinds of conventional antidepressants. This is the percentage of people who would be defined as ‘treatment-resistant’. Esketamine is proven to reduce depression symptoms in a majority of these people in clinical trials.

 

The only other approved drug therapy for treatment-resistant depression is a combination of Olanzapine (an antipsychotic drug) and Fluoxetine (a conventional antidepressant). However, this treatment has significant long-term effects that include substantial weight gain, metabolic changes, diabetes and high blood pressure.

Common antidepressants are slow-acting. It often takes several weeks to make a noticeable difference in how people with depression feel, says Kaplin. On the other hand, esketamine immediately impacts brain cells, offering relief from depressive symptoms within hours.

Research suggests that untreated depression causes long-term brain damage and is a risk factor for dementia. Studies show that people with depression have up to 20% shrinkage of the hippocampus, a region of the brain critical for memory and learning. But Esketamine may counteract the harmful effects of depression.

 

Animal studies indicate that connections between brain cells diminish under chronic stress, but Esketamine reverses these stress-related changes. Esketamine is different from any other antidepressant in that it not only prevents the neurotoxic effects of depression on the brain, but it also seems to have a growth-promoting effect
