Welcome back to the Deep Dive.

Today we have a stack of research that I think is going to hit close to home for a lot of people.

Oh, I think you're right.

We are looking at chapter 17 of Psychiatric Nursing, the seventh edition.

And honestly, this might be one of the most relatable chapters in the entire book.

I'd have to agree.

We're talking about anxiety.

Right.

And, you know, not just everyday stress, but the kind of clinical anxiety that, well, that requires chemical intervention.

We're decoding anti -anxiety drugs.

But before we get into the heavy chemistry and we will get into the liver enzymes and half -lives, because that's really where the safety issues live, I want to start where the text starts.

With a person.

With a human being.

Let's talk about Annie.

Annie is the case study that opens the chapter.

And I love that the text does this because anxiety is so incredibly subjective, you can't see it on an x -ray.

Right.

You can't measure it with a thermometer.

Exactly.

So let's set the scene properly.

Annie is just trying to do something normal.

She's at the movies, dark room, popcorn, you know, the big screen.

She's supposed to be relaxing.

And then suddenly she notices something tiny.

Just a little hitch in her breathing.

And that's the catalyst, isn't it?

That split second where you shift from experiencing the movie to monitoring your own body.

Exactly.

She starts paying attention to her breath.

And the text describes this cruel irony.

The more she focuses on breathing, the harder it becomes.

It feels like she can't get enough oxygen.

Yes.

And logically,

in her prefrontal cortex, she knows she's fine.

She literally remembers a nurse telling her recently, your oxygen saturation is perfect.

But logic has left the building.

Oh, completely.

The text has this really powerful line, knowing that it was all in her head did not seem to help.

That's the defining feature of an anxiety disorder right there.

The physiological sensation, that feeling of suffocation is absolutely real to the patient, even if, you know, the pathology isn't there.

And Annie describes it as entering a spiral.

It's like a nervous system, which, well, it begets more symptoms.

So she feels the breath shortage.

And that triggers palpitations.

Her heart starts hammering against her ribs, which then causes dizziness.

Now she's terrified she's going to faint.

And this is the part that really stuck out to me, the social terror.

It's not just that she's afraid of dying.

She's afraid of making a scene.

She's sitting there thinking, I'm going to lose control.

I'm going to start gasping for air.

And everyone in this theater is going to look at me and think I'm crazy.

That fear of judgment is what locks the trap.

It's the fear of the fear.

So our mission in this deep dive is to figure out how we intervene in that spiral.

When a patient like Annie comes to you, convinced she is dying, how do we use pharmacology to break that loop?

And it's a tricky business because as we're going to find out, the very drugs that stop that spiral are some of the most effective and yet some of the most dangerous tools in modern medicine.

We're talking about benzodiazepines.

The blessing and the curse.

Okay.

Let's unpack this.

I want to start with the history because looking at the source material, it seems like humanity has been, I don't know, desperate to find a chemical off switch for anxiety for, well, forever.

Since we lived in caves, probably.

And for about 99 % of human history, the only real answer we had was alcohol.

It's the oldest anxiolytic.

And it works.

It works.

It hits the GABA receptors, which we'll talk about, but it's a blunt instrument.

It destroys the liver, it ruins lives, and the dosing is, let's say, imprecise.

To say the least.

Then we get to the 20th century.

The text mentions things like bromo seltzers in the early 1900s.

Ah, the bromides.

Yeah, you'd see these in old newspaper ads.

Settle your nerves.

They were sold over the counter, but they were, frankly, toxic.

They built up in the body and caused psychosis.

So they literally drove people mad trying to calm them down.

That's a good way of putting it, yes.

Then we had the barbiturates in the 30s and 40s.

Which was a step forward, chemically speaking.

A step forward in chemistry, maybe, but a huge step backward in safety.

Arbiturates are incredibly effective at knocking you out.

But the therapeutic index, the gap between calm and dead,

is razor thin.

So you take two pills to sleep, you're fine.

You take four, you stop breathing.

It's that simple.

And then 1955, this is the moment that really caught my attention in the reading, the arrival of Miprobami, brand name, Milltown.

Milltown wasn't just a drug.

It was a cultural phenomenon.

You have to understand the vibe of 1950s America.

The war is over, the economy is booming, the suburbs are exploding.

But everyone is neurotic.

It's the age of anxiety.

Exactly.

And Milltown was marketed differently, wasn't it?

It wasn't just for sick people.

No, it was the first lifestyle drug.

The text says it had this unique ability to blur the reality of stressors.

It didn't knock you out like a barbiturate.

It just, it put a soft filter on the world.

Blur the reality of stressors.

I mean, that sounds incredibly appealing.

It does.

It was marketed to the busy executive, the stressed housewife.

There were Milltown parties.

It was called Peace Pill.

It reflected this deep American desire to buffer against the speed of modern life.

But like everything else before it, there was a catch.

A big one.

It was physically addictive.

People built up tolerance rapidly, so they needed more and more to get that blur.

And if they tried to stop.

The withdrawal was brutal.

Hallucinations, seizures.

It turned out that blurring reality came at a very, very high physiological price.

Which sets the stage perfectly for the late 50s.

The chemists go back to the drawing board, looking for the Holy Grail.

A drug that calms you down but doesn't kill you.

And they find the benzodiazepine.

Specifically, Chlordiazepoxide, or Librium, followed quickly by Diazepam or Valium.

That's right.

And why were these considered such a game changer compared to

Milltown or the, the terrifying barbiturates?

Safety.

Or more accurately, relative safety.

Yeah.

They were much less likely to be lethal if taken on their own.

They didn't depress the respiratory center of the brain as aggressively as barbiturates did.

So you could take a handful, don't do this obviously.

It's gonna need growth.

But you would likely just sleep for a long time rather than stop breathing.

That's the idea.

But the text includes a Norm's Notes.

I love these little sidebar warnings.

That basically screams, caution.

Can you spell addiction?

That's the quote.

It warns that benzos are great for a short while when you are really anxious.

Like Annie in the movie theater, they work fast.

But long -term use.

The text is blunt.

It generally does not lead to anything good.

And it says addiction can happen to anyone.

Yes.

Your patients, your family, even the nurse themselves.

We have to remember, you know, nurses have high -stress jobs and access to medications.

The text is very clear that no one is immune to the chemistry of dependence.

So we have this tension right from the start.

A drug that works incredibly well but has a hook inside it.

A very sharp hook.

Okay.

Before we get into how the drug works, let's look at the biology of the anxiety itself.

The text outlines three causative factors.

What's going on in the body when Annie is freaking out?

Right.

To understand the cure, you have to understand the malady.

The text lists three main areas.

First, autonomic dysregulation.

This is the sympathetic nervous system going haywire.

Exactly.

The fight -or -flight response is stuck in the on position.

Your body thinks it's being chased by a bear.

So tachycardia, sweating.

Racing heart, sweating, dilated pupils, all of it.

Second is neuroendocrine overactivity.

That sounds complicated.

It just refers to the hypothalamic -pituitary -adrenal axis, the HPA axis.

It's pumping out too much cortisol.

It's a stress hormone.

That's the one.

It keeps the body in a state of high alert.

Yeah.

And third is faulty thinking.

This is the cognitive aspect.

The what -if thinking.

Catastrophic thinking.

What if I faint?

What if I die?

What if everyone is looking at me?

Exactly.

There's a diagram in the text, figure 17 to 1, that visualizes this as a loop.

It connects the sympathetic nervous system, the respiratory system, and the neuromuscular system.

It's a vicious cycle.

Let's trace it.

Your heart races, right?

That's the sympathetic system.

This makes you feel like you need more air, so you breathe faster.

That's respiratory.

Hyperventilation.

Right.

And hyperventilation changes your blood chemistry slightly, which makes your muscles tense and tremble.

Neuromuscular.

And the brain feels that trembling, feels the racing heart, and thinks.

Danger.

And it tells the heart to beat even faster.

And around and around you go.

So chemically, what's driving this bus?

The text points to a tiny area in the brainstem called the locus surulius.

Locus surulius.

Think of this as the norepinephrine factory of the brain.

In anxiety, the locus surulius is working overtime, overproducing norepinephrine, which is basically adrenaline for the brain.

But there's another player here, the hero of our story, or maybe the victim,

GABA.

GABA.

Gamma -amidobutyric acid.

The most important inhibitory neurotransmitter in the brain.

The brake.

Yes, the brake.

The theory is that in anxiety, GABA inhibition is lifted.

Lifted.

What does that mean?

Well, normally GABA keeps things in check.

It's the wet blanket on the fire.

If that wet blanket is removed or lifted,

the adrenergic system, the adrenaline system, is allowed to run wild.

And venzos work by fixing this specific problem.

They boost GABA.

They put the wet blanket back on the fire.

Okay, let's get into the mechanics of that.

How do these drugs actually work?

The text talks about GABA.

Right.

To understand benzos, you have to understand the GABA receptor.

Imagine your brain is a car.

Okay, I'm driving.

And anxiety is the car coasting downhill, picking up speed.

The engine is racing.

It's becoming a runaway vehicle.

Right.

GABA is the brake pedal.

So when I have an anxiety attack, my brakes are failing.

Not necessarily failing, but they aren't being pressed hard enough to counter the speed.

Here is the common misconception.

People think benzos are a new set of brakes.

That the drug enters the brain and stops the car.

Exactly.

That's not what happens.

A benzodiazepine is useless on its own.

It is an allosteric modulator.

Okay, break that down for me.

Allosteric?

It just means other site.

Picture the GABA receptor.

It's a complex little flower sitting on the nerve cell.

GABA has its own parking spot on that flower.

When GABA parks there, the center of the flower opens up a channel.

And chloride rushes in.

And chloride is the calm down chemical.

Chloride is negatively charged.

When it rushes into the nerve, it makes the nerve more negative.

It hyperpolarizes it.

A negative nerve is a sleeping nerve.

It won't fire.

It won't panic.

So where does the benzo park?

The benzo parks in a different spot on that same flower.

It doesn't open the channel itself.

It just sits there.

So what does it do?

This is the magic.

When the benzo is parked in its spot, it changes the shape of the flower slightly.

It makes the GABA spot stickier.

Ah, so it makes my natural GABA work better.

Exactly.

It's like power steering for your brakes.

You are still pressing the pedal.

That's your natural GABA.

But the benzo makes that pressure 10 times more effective.

The channel opens wider and stays open longer.

This explains why they are so much safer than barbiturates, doesn't it?

This is the most critical safety concept for any nursing student listening.

Barbiturates, the dangerous old drugs, could force that channel open without GABA.

They didn't need the driver to press the brake.

No.

They could just slam the tar to a halt, which means they can stop the heart and lungs completely.

Because they have no ceiling.

Right.

You take enough, you turn the brain off, dead.

But benzos, they require your natural GABA to work, and your body has a limit on how much GABA it can produce.

So there's a natural ceiling to how much effect a benzo can have.

Exactly.

Even if you take a massive handful of valium, if there isn't enough natural GABA to facilitate the action, the effect plateaus, it is much, much harder, though not impossible, to lethally overdose on benzos alone because they are limited by your own biology.

That is a fascinating distinction.

Enhancers versus mimics.

It makes all the difference in the world.

So we enhance the GABA.

What do we actually get out of it?

The text breaks down the therapeutic effects based on how many receptors are occupied.

It's interesting that it's not just on or off.

No, it's a spectrum.

If you occupy about 20 % of the receptors, you get the anxiolytic effect.

The anxiety goes down.

That's the sweet spot for someone like Annie.

That's what we're aiming for.

But if you take a little more.

And hit 30 -50 % receptor binding.

Now you get sedation.

You promote sleep.

This is why benzos are so often prescribed for insomnia.

And if you go even higher, say 60%.

Hypnosis and amnesia.

This is used intentionally in surgery or conscious sedation.

You're awake, but you aren't forming new memories of the procedure.

The text also mentions the reticular activating system or RAS.

It says benzos depress this system.

What does that mean for the patient?

The RAS is your brain's filter.

It handles environmental scanning.

Think about an anxious person.

They're constantly scanning the room.

What was that noise?

Who was looking at me?

Is that a threat?

Their radar is turned up to maximum sensitivity.

It's exhausting.

Benzos mute the RAS.

They turn down the gain on that radar.

You stop scanning.

You stop reacting to every little stimulus.

The world becomes a little quieter.

That sounds like pure relief.

But, as we know, you can't get something for nothing.

Section 4 of our outline covers the dangers.

Peptidoxical reactions and disinhibition.

Let's talk about disinhibition.

This connects back to that carefree zone mentioned in the text.

We have inhibitory neurons in the brain, specifically in the prefrontal cortex, that control social restraint.

They're the voice in your head that says, don't say that rude thing or don't dance on the table.

Exactly.

And benzos suppress those neurons.

So, similar to alcohol, you get disinhibited.

You feel euphoric, maybe a bit excited, but your judgment is impaired.

You might say things you wouldn't normally say.

Or do things you wouldn't normally do.

This is the high that leads to recreational abuse.

And what about paradoxical reactions?

This one is scary.

You give a drug to calm someone down and they go berserk.

It happens.

And it's a nightmare for nurses.

Instead of sedation, the patient becomes agitated, emotionally labile, talkative, or even filled with rage.

Who is at risk for this?

It's usually the extremes of age, children and older adults.

Also people with poor impulse control to begin with.

And why does it happen?

The theory is that the drug disinhibits the prefrontal cortex,

the part of the brain that says, don't punch that person.

If you suppress the don't punch filter, you might get a punch.

That is a crucial thing for a nurse to watch for.

If grandma starts throwing her dinner tray after her edivon, she's not necessarily psychotic.

She might be having a paradoxical reaction.

And you don't give her more edivon, you have to stop it.

Let's move to what I think is the exam question goldmine of this chapter.

Pharmacokinetics.

Specifically, what the liver does with these drugs.

If you remember one thing from this deep dive, make it this section.

Because this is where nurses kill patients.

Whoa.

Okay, the stakes are high.

They are.

It comes down to two pathways in the liver.

Oxidation and conjugation.

Okay, let's start with oxidation.

This is the the dirty pathway.

Think of it as the complex pathway.

Drugs like Diazepam Valium and Chlordiazapoxylibrium go through oxidation.

The liver takes the drug and attacks it with enzymes.

But it doesn't just destroy the drug, it breaks it into pieces.

And here's the kicker.

The pieces are also drugs.

These are the active metabolites.

Yes, you take a Valium, your liver chops it up.

One of the leftover pieces is a chemical called Desmethyldeazepam.

And guess what?

Desmethyldeazepam is also an anti -anxiety drug.

And it stays in the body for a very, very long time.

So you have the ghost of the drug still haunting your system even after the pill is gone.

Perfect analogy.

Now add aging to the mix.

As we get older, our livers shrink, blood flow drops.

The enzymes that do this oxidation work get tired and slow.

The text has a stat here that actually made my jaw drop.

The half -life of Diazepam.

It's the age equals half -life rule, roughly.

And a 20 -year -old, the half -life of Valium is about 20 hours.

And an 80 -year -old, it could be 80 hours.

Let's play that out.

I'm 80 years old.

I take a Valium on Monday night to sleep.

Tuesday night, you still have about 80 % of it in your blood.

But you take another pill.

Right.

By Friday, you are toxic.

You have Monday's ghost, Tuesday's ghost, Wednesday's ghost.

You're confused.

You're dragging your feet.

You look like you have dementia.

And then I get up to use the bathroom, trip on a rug, and break my hip.

And that hip fracture leads to pneumonia, which leads to, well, you know, the spiral.

So if we can't give Valium to grandma, what do we give her?

Because she still has anxiety.

We switch to the second pathway, conjugation.

Clean pathway.

The education is simple.

The liver just slaps a sugar molecule onto the drug.

It's like putting a fragile sticker on a box.

Doesn't chop it up.

It just tags it for export.

And then boom, straight to the kidneys.

Peed out, no active metabolites, no ghosts.

Yeah, and crucially.

This process does not slow down with age.

An 80 -year -old liver conjugates almost as fast as a 20 -year -old liver.

So we need to know which drugs use this clean pathway.

There's a mnemonic for it.

L -O -T.

L -O -T.

Lorazepam, antavon, oxazepam, Serax.

Yeah.

And temazepam, restorative.

So if I see a prescription for Valium for an 85 -year -old.

You question it.

You call the provider.

You advocate for your patient.

You suggest one of the lots of drugs that is safe nursing practice.

L -O -T, Lorazepam, oxazepam, temazepam.

Got it.

OK, let's talk about the downside of taking these drugs.

Side effects, dependence, and withdrawal.

The common side effects are what you'd expect from a CNS depressant.

Drowsiness, fatigue,

ataxia, which is loss of coordination.

And anterograde amnesia, no new memories.

Right, which can be dangerous.

A patient might take a pill and then have a conversation with the doctor, and an hour later, they won't remember a word of it.

Or they might cook a meal and forget they left the stove on.

Exactly.

The text also distinguishes between subjective anxiety and objective signs in Box 17 -3.

This seems important for how we chart.

Very important.

Subjective is what the patient feels and tells you.

Dread, fear, I'm going to die.

Objective is what the nurse sees.

Tremors, dilated pupils, restlessness.

You need to document both to track if the medication is actually working.

Now, the text calls out the triple problem.

Dependence, withdrawal, and tolerance.

Let's break those down.

First, dependence.

Dependence means the body has adjusted to the drug and now functions abnormally without it.

The text lists three types.

First, therapeutic dose dependence.

This is the patient who takes it exactly as prescribed.

Yes.

But over time, they simply need it to get through the day.

The original crisis has passed, but they can't stop.

Then there's high -dose dependence.

This is the patient engaging in doctor shopping or pushing their provider for higher and higher doses.

And third is recreational abuse, often mixing it with other substances to boost the high.

Which leads directly to withdrawal.

Why is benzo withdrawal so dangerous?

The text mentions seizures.

Think back to our brake pedal analogy.

You've been artificially pressing the brake -enhancing GABA for months or years.

Your brain, trying to maintain balance, has said, OK, we have too much braking going on.

I'm going to reduce my own natural brakes.

It down -regulates the GABA receptors.

It physically removes some of them.

So if you yank the drug away abruptly.

You have a car with no brakes speeding downhill.

Exactly.

The brain goes into a runaway expectation state.

Agitation, insomnia, sweating, and in severe cases, convulsions or seizures.

So the rule is, never stop cold turkey.

Never.

You must taper.

And the taper can take weeks or even months.

You have to give the brain time to regrow its own brakes.

And finally, in the triple problem, tolerance.

This is tricky because tolerance develops at different speeds for different effects.

Tolerance to the sedation?

The sleepiness develops quickly, within weeks.

So patients will say, it doesn't make me sleepy anymore.

Right.

But tolerance to the anti -anxiety effect develops much more slowly over months.

So the patient is still calm, just not sleepy.

But the text notes one thing tolerance does not develop to.

The memory deficits,

the amnesia.

You never really get used to that.

That impairment stays as long as you take the drug.

You are constantly operating at a slight cognitive deficit.

Moving on to interactions and overdose.

We established that benzos are hard to overdose on by themselves due to that ceiling effect.

But they are rarely taken by themselves in overdose scenarios.

The deadly multiplier is alcohol or opioids.

Any other CNS depressant.

Why is the combo so bad?

It's synergistic respiratory depression.

One plus one equals five.

Alcohol opens the chloride channel.

Benzos hold it open longer.

The result is that the drive to breathe in your brainstem just shuts down completely.

And let's talk about a breakfast food.

Grapefruit juice.

Ah, classic nursing board question.

Grapefruit juice contains compounds that inhibit the CYP -453A4 enzyme in the gut.

Okay, simplify that for us.

Imagine the enzyme is a security guard in your liver that destroys some of the drug before it ever gets into your blood.

Grapefruit juice comes in and handcuffs a security guard.

So more of the drug walks right past.

Exactly.

So if you take your normal dose of Xanax with a big glass of grapefruit juice, you might absorb two or three times as much drug as you intended.

You effectively overdose yourself.

Now let's say the worst happens.

A patient overdoses.

We have an antidote.

Flumazenil, brand name Ramazicon.

Yes.

Flumazenil is a benzodiazepine receptor antagonist.

It blocks the receptor site.

It literally kicks the benzo off the flower.

And the tech says it works fast.

30 to 60 seconds.

It's dramatic.

The patient goes from a coma to talking to you in under a minute.

Yeah.

And this is a huge, but there's a nursing trap here.

What's the trap?

The half -life.

Flumazenil has a very short duration of action.

Much, much shorter than the benzo, especially a long -acting one like Valium.

So you give the antidote, the patient wakes up.

You think, great, job done.

You walk away to chart.

And then what happens?

The flumazenil wears off after an hour or so.

But the Valium is still in their system.

The patient slips back into the coma.

And stops breathing again.

So vigilance is key.

Constant vigilance.

You often need repeat doses, maybe even a continuous drip.

And there's another risk.

Seizures.

Why seizures?

If a patient is physically dependent on benzos, if their brain has removed its own brakes and you slam them with flumazenil, you are ripping the artificial break off instantly.

You can precipitate a massive withdrawal seizure right there in the ER.

OK, let's do a quick tour of the specific drugs.

I want to give the listener a feel for the personality of each one mentioned in section 8.

Start with Alprazolamine, Xanax.

Xanax is a sprinter.

It hits hard and fast, which makes it useful for panic attacks.

But it wears off fast.

This promotes interdose anxiety.

You start craving the next pill before it's even time.

It has a very high abuse potential.

Chlordiazapoxide, Libria.

The grandfather.

Very old school.

Mostly used now for managing alcohol withdrawal tremors.

It has a very long half life.

So you keep it away from the elderly.

Klonosapin.

Klonopin.

The steady hand.

It's actually classified as an anticonvulsant, but is used for panic.

It's weakly lipophilic, so it doesn't rush into the brain as fast as Xanax, meaning less of a high.

But you have to taper it very slowly to avoid status epilepticus.

Diazabam.

Evaluum.

Is it at all?

Anxiety, muscle spasms, pre -surgery jitters.

It comes in IV form for stopping seizures right now.

But again, huge half life issues in the elderly because of those active metabolites, those ghosts.

And lorazapam, Ativan.

The reliable workhorse.

It's one of the Lwadi drugs, so it has that clean metabolism, the conjugation.

It's good for the liver, good for the elderly.

It's the go -to in the ER, often mixed with Haldol for agitated patients.

Last one, Oxacepam.

Sarax.

The gentle one.

Also a lot drug.

It's similar to Ativan, but often used for patients who have trouble with sleep or milder forms of anxiety.

Short acting.

Good for older adults.

Okay, we've spent a lot of time on benzos, but the chapter discusses alternatives.

The non -benzodiazepines,

specifically busperone.

Busperone is fascinating because it breaks all the rules we just discussed.

It does not bind to GATA.

It works on serotonin receptors.

It's a 5 -HT1A agonist.

So what are the pros?

Why use it?

No sedation, no high, no abuse potential, no withdrawal.

You can drive a car on it.

It's much, much safer from a dependence standpoint.

What's the catch?

There's always a catch.

It's the tortoise to Xanax's hair.

It is slow.

It takes one to six weeks to reach its full effect.

So you can't take it for a panic attack that's happening right now?

Absolutely not.

It's for chronic worry for generalized anxiety disorder.

And here's the key nursing strategy.

You cannot just swap a patient from Xanax to busperone overnight.

Because the busperone won't work for weeks.

And the patient will go into benzo withdrawal in the meantime.

You have to overlap them.

Start the busperone and then slowly taper the benzo while the busperone builds up in their system.

The text also mentions SSRIs briefly, even though they're covered in another chapter.

It uses an analogy I really liked.

Antibiotics versus aspirin.

Yes, from box 17 to 6.

Think of the benzo as aspirin.

It treats the symptom, the pain, the anxiety immediately.

But it doesn't fix the underlying cause.

It's a band -aid.

It's a very effective band -aid.

Yeah.

The SSRI, like Prozac or Zoloft, is the antibiotic.

It takes time to work, but it treats the underlying problem, the neurochemical imbalance, over the long term.

So SSRIs are the first line for things like GD, OCD, and panic disorder.

Yes.

Even though they are antidepressants, they are the gold standard for long -term anxiety treatment.

The text notes they eventually upregulate GABA in the prefrontal cortex, bringing us right back to our friend GABA.

Finally, let's hit the off -label drugs.

Section 10.

Beta blockers.

Propranolol.

This is a heart medication.

It blocks beta receptors.

It doesn't really touch the anxiety in your mind, but it stops the physical symptoms.

It stops the racing heart and the shaking hands.

So this is for stage fright.

Social phobia.

If you have to give a speech and you don't want your voice to shake, propranolol is the drug.

It breaks the loop by stopping the physical symptoms from feeding back to the brain.

Antihistamines.

Hydroxyzine or Vistrol.

It's basically a strong allergy pill that makes you sleepy.

It's non -addictive, which is its main selling point.

It's great for patients with a history of substance abuse because you can't get high on it.

And gabapentin.

Originally for seizures and nerve pain, but it inhibits neuronal excitability.

We're seeing it used more and more for social phobia and generalized anxiety.

We're coming to the end here.

Let's recap the nursing implications.

If I'm a student walking into a clinical exam, what are the bullet points I absolutely need to know?

Let's drill them down.

One, safety first.

These patients are drowsy and uncoordinated.

Fall precautions are mandatory.

And no driving until they know how the drug affects them.

Two.

Two,

pregnancy.

Generally a no -go.

Benzos can cause floppy infant syndrome and are excreted in breast milk.

Three.

Three,

patient teaching.

The big ones.

Don't increase your dose on your own.

Don't drink alcohol.

And for the love of everything, do not stop cold turkey.

And four, cross -tolerance.

Right.

Understand that a heavy drinker has a liver that is used to processing depressants.

They might need a massive dose of Valium just to feel an effect because of that cross -tolerance.

But, and this is vital, the respiratory depression risk doesn't change?

Correct.

Their brain might be awake because of tolerance, but their breathing drive is still sensitive.

You can stop their breathing even if they're looking right at you.

It's a very dangerous mismatch.

So we've moved from the runaway brain of Annie to the break of Gabba.

We learned why we protect the elderly from the ghosts of Valium using the lot drugs and why Flumazenil requires constant vigilance.

It's been quite a journey through Chapter 17.

It really highlights the balancing act of psychiatric nursing.

We have these tools, the benzos, that are incredibly effective at relieving suffering instantly.

But the cost is potential dependence and all the problems that come with it.

The text ends with a provocative thought that I want to leave our listeners with.

It mentions that drug companies are constantly searching for the perfect anti -anxiety drug one with no side effects, no sedation, no addiction.

But it raises a really interesting question.

Anxiety is the survival mechanism.

It's our alarm system.

Is it even biologically possible to turn off the alarm system without dulling the mind?

Can you have a fearless brain that is also perfectly sharp and safe?

The search continues.

It certainly does.

Thanks for diving deep with us.

A warm thank you from the Last Minute Lecture Team.

See you next time.
