Rapid-acting antidepressants like ketamine can restore dark emptiness to joy.Smash Treatment-Resistant Mood Disorders with Rapid-Acting Antidepressants: Like Ketamine Treatment

We’ve talked before about the line to the throne where ketamine treatment now reigns. Formulators in a lab were seeking to create a new anesthesia, and they thought they’d found one.  They called it Sernyl—but the unpredictable side effects, hallucinations, and sometimes violent behavior, drove the pharmaceutical company to take it off the shelves.

It was not the kind of medicine doctors wanted to give their patients. Rapid-acting antidepressants help you get better fast. Through a series of leaks and improprieties however, it began to drift onto the streets as an illegal substance. The drug was phencyclidine, or PCP. Remember during the ’70’s and ’80’s? If so, you know the havoc that PCP – or angel dust – wreaked on the street crowd.

Rapid-acting Antidepressants

But those researchers weren’t willing to give up. They kept working and developed another safer anesthesia that had some of the dissociative properties Sernyl had, but less in side effects when used at therapeutic doses.

They coined it a “dissociative anesthesia” and it became internationally popular in the surgical suite, in the emergency department, and in war zones around the world.

That medicine was ketamine hydrochloride. And testing for treating depression began forty years after ketamine was developed and widely used as an anesthetic. 

And we’re now seeing outstanding results, as in remission of depression and other mood disorders, in both research studies and the clinical setting.

So it’s not surprising, is it? That ketamine treatment has become the role model for emerging new medicines that treat mood disorders. 

Still, knowing what ketamine treatment can do for major depression, Rapid-acting antidepressants like ketamine treatment restore inner joy.postpartum depression, social anxiety, bipolar disorder, PTSD, OCD, and suicidal thinking isn’t enough for neuroscience researchers.

They want more.

If ketamine does great work treating patients with treatment-resistant mood disorders, there must be more medicines that will also work as well.

Or so they hope..?

Antidepressants that Work as Well as Ketamine Treatment

So the search is on to find other rapid-acting antidepressants that eradicate major depression, PTSD, bipolar disorder, OCD, social anxiety… and stop suicidal thinking in four hours…or less, like ketamine treatment does.

It’s a tall order, but it’s the quest of the hour.

Conventional antidepressants improve symptoms by increasing levels of neurotransmitters like serotonin and norepinephrine.

But it takes 9-12 weeks or more for someone to experience that improvement. So the loud and strong need for rapid-acting antidepressants shouts its demand for these solutions.

Why? Because when patients with severe disorders are inundated Rapid-acting antidepressants like ketamine treatment bring relief to despair.with thoughts of suicide, if those thoughts can’t be eradicated quickly, the risk of death is high.

In addition, lost work time as well as abandonment of  the medication regimen, is more likely to happen. In short?  Patient safety is compromised.

Seeking Ketamine Wannabes

So, there’s a strong focus on compounds that CAN bring fast relief. They include ketamine, scopolamine, and “mechanistically-related” compounds. We’ll get to those in another blog post.

But researchers added some newer ones to this list in the surge to find more rapid-acting medicines.

Compounds like:

  • Antagonists of metabotropic (mGlu) 2/3 receptors
  • Negative allosteric modulators of α5-containing GABA A receptors
  • Psychedelic compounds like psilocybin

I know…I know… sounds like Greek.

How about this?

These compounds need to demonstrate their effectiveness in large groups of people. Most importantly, when medications fail to help people get better, these compounds need prove they can be effective.

And…as always…the biggest challenge is finding ways to make the positive effects last.

Rapid-Acting Antidepressants Help You Get Better Fast

Since the use of ketamine for depression began, the path of discovery started when ketamine first caused remarkable relief for depressed patients, but that relief didn’t last more than a few days or a week.

Researchers tested a variety of methods, and discovered an effective regimen was 6 ketamine infusions given every few days over 2 weeks.

By doing this, it seemed to bypass the short term beneficial effects Rapid-acting antidepressants deliver relief and peace to those who suffer with treatment-resistant mood disorders.and instead prolong them. As we’ve moved forward in clinical practice, we’ve found that increasing the number of infusions in some cases can ensure remission. That is, if the initial six fell short of that goal. And we’ve worked with different infusion protocols over 2-3 weeks.

Like all aspects of psychiatry, personalizing the treatment to fit the patient’s needs yields the most effective outcomes.

Review of Literature Clarifies the Search

A brand new review was published in Current Pharmaceutical Design July 29 focused on these specific compounds and their potential. The team, led by Jeffrey M. Witkin, reviewed the current literature on compounds that produce immediate symptom relief.

They determined that a foremost system for producing rapid effects is by amplifying excitatory neurotransmission (by glutamate) while activating AMPA receptors.

These drugs cause glutamate to flow out of the cells which provide what researchers hypothesize is a triggering mechanism to increase the amplitude of AMPA receptors. 

They concluded that the focus in pharmaceuticals these days is rapid-acting antidepressant compounds like ketamine, scopolamine, and psilocybin. All of these need extensive study. And they pointed out that two medicines, rapastinel and esketamine are in the last stages of FDA trials.

So let’s look again at the up and coming compounds and medicines in the running to potentially supply the benefits that ketamine is now providing:

  • Ketamine — still at the top
  • Esketamine (developed by Jansen, a division of Johnson & Johnson)
  • Rapastinel (developed by Allergan)

It’s probably fair to say that in the next few years we’ll be bombardedRapid-acting antidepressants bring hope in darkness for those with treatment-resistant mood disorders. with many new medicines that operate quickly to treat mood disorders. But that’s the way of progress.

Even though esketamine is only half the ketamine molecule — with its own challenges and problems — it’s generating anticipation despite the problems that can come with an intranasal medication.

Keep in mind that FDA approval doesn’t guarantee a medicine is superior to others. But it’s a sign we’re in a new era of better, faster, and more effective medicines for psychiatric disorders.

Ketamine still reigns supreme. And physicians will likely need to combine esketamine with traditional antidepressants and mood stabilizers. Even so, mood disorder treatment is better than it used to be. Remember before ketamine treatment?

Back then, it was necessary to wait for weeks or months to enjoy the benefit of a medicine.

Times are changing and suffering is declining.

At Innovative Psychiatry, we’re celebrating the onward development of pharmaceutical progress, while also providing the outstanding benefits that ketamine can offer to our patients with treatment-resistant illnesses.

Our specialty is treating disorders that haven’t gotten better with other treatments. We’re here because we want to help you experience life like you were meant to live it.
