Esketamine (Spravato): Uses, Dose, Side Effects, Reviews, Price

What Is Esketamine (Spravato) And What Does It Treat?

Esketamine (Spravato) is an intranasal medication that works in the brain. Esketamine is made from a drug called ketamine, an anesthetic that has also been used for many years to treat depression. But it wasn’t until recently that esketamine, a more potent version of ketamine, earned FDA approval specifically for use as a nasal spray for those with treatment-resistant depression.

Esketamine (Spravato) is approved for the treatment of treatment-resistant depression (TRD) in conjunction with an oral antidepressant. It is also FDA approved for major depressive disorder (MDD) with suicidal thoughts and behavior.

Esketamine (Spravato) is used in combination with other antidepressants when at least two other treatments have failed to treat depression.

Symptoms of depression include:

•                Depressed mood – feeling sad, empty, or tearful

•                Feeling worthless, guilty, hopeless, and helpless

•                Loss of interest or pleasure in your usual activities

•                Sleep and eat more or less than usual (for most people it is less)

•                Low energy, trouble concentrating, or thoughts of death (suicidal thinking)

•                Physical aches and pains such as headaches, stomach issues, or muscle pains

•                Psychomotor agitation (‘nervous energy’)

•                Psychomotor retardation (moving and thinking in slow motion)

•                Suicidal thoughts or behaviors

How does Esketamine (Spravato) work to treat depression?

Esketamine (Spravato), and its related drug ketamine, are highly effective depression treatments for a number of reasons:

  • Esketamine (Spravato)’s antidepressant function works through a different mechanism than other drugs. Conventional antidepressants increase 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 (Spravato) works in a similar fashion, but unlike other antidepressants it increases levels of glutamate, the most abundant chemical messenger in the brain. The result? A greater impact on more brain cells at one time.

What Is The Most Important Information I Should Know About Esketamine (Spravato)?

Do not stop taking esketamine abruptly, even when you feel better. With input from you, your health care provider will assess how long you will need to take the medicine.

Missing doses of esketamine may increase your risk for relapse in your symptoms of depression.

Physical dependence and potential abuse have been reported with prolonged use of ketamine. This can lead to withdrawal signs and symptoms after abrupt discontinuation or a reduction in the drug dose. Likely withdrawal symptoms associated with esketamine include craving, fatigue, poor appetite, and anxiety. Therefore, patients should be monitored for symptoms of dependence after esketamine treatment has ended.

Esketamine (Spravato) can cause excess sedation (sleepiness) in patients after they receive treatment. You will need to remain in the health care setting for at least 2 hours (or more) until it is determined by the provider that you are safe to go home. You will need to have a caregiver drive you home.

Because of the risk of serious adverse effects resulting from excessive sedation, esketamine is only available through a restricted program called SPRAVATO REMS. Esketamine (Spravato) can only be administered in a health care setting certified in the SPRAVATO REMS Program and to patients enrolled in the program.

What Should I Discuss With My Health Care Provider Before Taking Esketamine (Spravato)?

•                Symptoms of your condition that bother you the most

•                If you have thoughts of suicide or harming yourself

•                Medications you have taken in the past for your condition, whether they were effective or caused any adverse effects

•                If you experience side effects from your medications, discuss them with your provider. Some side effects may pass with time, but others may require changes in the medication

•                Past or current medical history, especially history of aneurysms, brain bleeds, or allergy to esketamine or ketamine

•                Any other psychiatric or medical problems you have, including high blood pressure as esketamine can increase blood pressure.

•                All other medications you are currently taking (including over-the-counter products, herbal and nutritional supplements) and any medication allergies you have.

•                If you are pregnant, plan to become pregnant, or are breast-feeding

•                If you drink alcohol or use drugs
