Dr Sanil Rege starts this video by discussing the Alpha 1 and Alpha 2 adrenergic receptors and their mechanism of action. He then discusses the mechanism of action of Prazosin and Clonidine in the context of the Alpha 1 and Alpha 2 receptors. Prazosin is an Alpha 1 adrenergic receptor antagonist and Clonidine is an Alpha 2 adrenergic receptor agonist. Finally, he shares his practical clinical experience with regards to both agents covering indications, optimum doses and side effects.
00:00 - Intro
00:37 - Role of Alpha 1 receptor and Prazosin
02:55 - Role of Alpha 2 receptor | Clonidine and Guanfacine
06:41 - Clinical application of Clonidine and Prazosin in Psychiatry
Discussion points:
Prazosin
• Unique therapeutic effects on nightmares and sleep disturbance associated with PTSD
• Orthostatic hypotension as a main side effect
• Minimum abuse potential
Clonidine
• Sleep deprivation is known to affect the clearance of metabolic waste products in the wakefulness pathways governed by locus coeruleus (NA neuron projections)
• Thus, manipulation of noradrenergic tone may enhance glymphatic clearance providing a neuroprotective effect for the brain.
• Clonidine is an α2 agonist (high affinity for all 3 α2 -receptor subtypes, α2A, α2B and α2C) which is known to increase NREM sleep. While low doses (e. g., 25 μg) have little effect on REM sleep, 150 mcg clonidine reduces REM sleep by about 50 %.
• Indications include primary insomnia in the paediatric population, insomnia in the context of ADHD, ASD, PTSD and Borderline personality disorder. [Nguyen et al., 2013], [Broese et al., 2012]
• Guanfacine is also an α2 agonist (specific α2A). Higher doses of about 2 mg can reduce REM sleep by 26 % which is less marked than clonidine.

As a scientist who likes to REALLY understand medications I'm prescribed... this video is fantastic! I always remind my doctors or pharmacists that I WANT them to actually tell me everything they know about how stuff works. Some of them really get a kick out of being allowed to geek out in a way that most patients DON'T want. I don't want to take up their time too much though, so this video answered all of the detailed questions I had about how Clonidine works and was easy to follow. Thanks again!

This video is great. I have a very tough situation that my doctors are having trouble doing anything about and I’d really appreciate your information. Of course, I will not take anything you say as medical advice. I suffered an ischemic repurfusion injury and resulting peripheral neuropathy after getting frostbite in one of my limbs. I’m in severe pain constantly and unable to walk for normal intervals. I have reduced blood flow to the limb and nerve pain. I am on both prazosin and Clonodine for sleep and nighttime anxiety. I am now worried that by being on this heavy combo and reducing my blood pressure so much, I am further reducing blood flow- impeding healing, and even causing ischemic repurfusion by going back and forth between hypotension and regular BP. I’ve been suffering from this for 2 years unable to walk normally and I am so desperate to heal so I’m very worried at this possibility. Is this a possibility? And if I were to go off of one, which one have the least risk of reducing blood flow? I don’t want to choose the one that has the biggest anxiety or pain relieving properties, I am on drugs for that already, but I want to choose the one that has the least risk of reduced blood flow. Thank you so much if you can answer.

How serious are the risks of discontinuation/withdrawal/rebound effects with Clonidine? There's really not much information on that online, at least not at the same as other medications. Most tapering schedules that do exist are for BP patients, not for ADHD or any of the other uses that it is currently prescribed for. For example, if a patient was using it as needed or short term (2-3 weeks) what kind of taper if any would be suggested? What is considered long term use with Clonidine? A week? A month? 6 months?
@PsychiatrySimplified
@PsychiatrySimplified 2 жыл бұрын
In general the rule is gradual tapering and avoid sudden stop ( rebound increase in BP). Long term could be longer than a year. It does not follow a hyperbolic curve like antidepressants do so gradual reduction over a few weeks under medical supervision is usually the way for doses 150mg and below. For higher doses this reduction may stretch out. Essentially patient BP is monitored and the speed of reduction depends on this as aim is to avoid rebound High BP. This may vary if it is used for BP Rx. The tapering over a few weeks is usually for psychiatric conditions. If however it is being discontinued for low BP - then usually it is stopped immediately as it is a SE. Ps- this is in general only and not specific medical advice

Thanks for this information! I have a question about dosage, specifically for Guanfacine. And yes, I did watch your other content where you go over Guanfacine. But in this video, you refer to the inverted U shape for optimal levels of catecholamine activity. Does the administration and dosage of alpha 2 agonists (mostly Guanfacine) associate directly with this U shape, in the same way that we would expect stimulants to do? I have not been able to find very much information on what "too little" or "too much" looks like when it comes to Guanfacine dosage, whereas the advice for stimulants seems to pretty pretty straightforward (too little = no effect, too much = hyperarousal). Perhaps this is less understood for Guanfacine. Also, the benefits CAN be immediate for Guanfacine, but usually take several days to weeks to appear, which makes this question more complicated. Personal context, if interested : After a few months of trying ADHD stimulants for the first time (minimal benefit), I recently started adding Guanfacine to my Vyvanse (30mg). A titration period of 2 weeks at 1mg, then 2mg. After 2 weeks at 2mg, I reflected back and had the impression of just the slightest bit of general benefit to impulsivity & time management, but it's often very difficult to say. However, talking with the pharmacist, we decided to try moving forward with 3mg. I immediately felt the sedative effects, which lasted just over a week. After the sedative effects stabilized however, I did not notice any general benefits to ADHD, still after almost 4 weeks (even taking a week off Vyvanse). And I would say that I even feel some hyperarousal, mentally & emotionally (physically, no). I personally believe that I may be dealing with some high glutamate levels, which might explain why the stimulants I have tried (adderall & Vyvanse) were only slightly helpful, but are a double-edged sword. So I was hoping the theoretic benefits of Guanfacine on inhibiting glutamate transmission would provide a more balanced focus, but I don't understand dosage (and neither does my doctor, to be honest!). So this is where my concerns are coming from. But perhaps I should shift my thinking from optimizing catecholamines and look more at the GABA balance. But I would love any insight you have on the Guanfacine! Thanks for the great content.

Hi, Yes, the Alpha2 receptor operates on the same basis. guanfacine plus Vyvanse can activate the alpha 2 and D1 - which can shift the individual towards the right side. too much. Before increasing the dose of a stimulant or adding an alpha 2 postsynaptic agonist- it becomes important to rule out hyperarousal e.g sleep difficulties, impulsivity, racing thoughts etc; if this is resent the benefits of PFC augmentation may be short-lived.

@@PsychiatrySimplified Hi, thanks for the response & good information. As I mentioned, it seems very likely that there is Hyperarousal. (impulsivity, racing thoughts, etc) If this is the case, how can this be ruled out? Also, how can treating both Hyperarousal & ADHD be addressed at the same time? The combination of guanfacine + stimulant might complicate the issue as you're saying, but does guanfacine on its own address both of these conditions, theoretically? Or, would you know of other possible considerations? And how can the hyperarousal itself be addressed? (I will speak with my doctor first, but it is helpful to get some orientation to know where to start) Thanks for the information!

Hi rege, Would beta blockers be useful in hyperaousal? Are alpha blocker more effective then beta blocker for hyperarousal treatment. If they are why so?
@PsychiatrySimplified
@PsychiatrySimplified Жыл бұрын
Beta blockers tend to have a greater peripheral actions rather than central. Centrally propranolol mainly crosses the BBB - but it reduces production thin o melatonin so can lead to nightmares ⬆️hyperarousal indirectly in some. Alpha 2 receptors are pre synaptic and hence act as feedback and reduce NA centrally and peripherally. Alpha 1 similarly does this. So overall for central hyperarousal alpha blockers would be preferred / beta blockers for peripheral e.g HR ⬆️ . This is a simple answer .

@PsychiatrySimplified
@PsychiatrySimplified 3 ай бұрын
Noradrenaline release is part of a stress response. NA acts in conjunction with other neurotransmitters hence clinical symptoms provide a better guide for management. For example a patient with ‘ADHD’ symptoms can have multiple other associated symptoms that helps build the formulation. Noradrenergic activation in the mesolimbic system can coexist with a reduced alpha 2 stimulation ( noradrenergic receptor for cognitive flexibility) in the PFC as alpha-1 ( noradrenergic receptor but excess stimulation leads to cognitive rigidity) overrides the alpha 2 a receptor. Hope that makes sense. Neurotransmitters operate as a group modulation, activation with the aim of reaching homeostasis. Clinical features act as clues telling us what the management plan should be to assist the individual to achieve this homeostasis. The video release on Sunday covers this in more detail.

In patients with ADHD, hyperarousal and sleep disorders, do you think it could be useful to combine Guanfacine during the day with clonidine at night (under monitoring blood pressure)? Do you have any further insights on clonidine and SubstanceP? One finds little information on this unfortunately. Substance P also seems to be associated with fibromylagia and tinnitus. And fibromylagia also occurs together with ADHD. Do you have any insights from your practice that tolerance can occur with cloning and guanafcaine over time? Thanks a lot!

In adhd and hyperarousal / sleep. There are both NA and DA affected. The main receptors that we aim to target are alpha 2a and D1 as they lead to therapeutic effects in frontal cortex. Alpha-2A in spinal cord postsynaptic facilitates descending pain inhibition. Alpha-2 a presynaptic agonist reduces hyperarousal and promotes sleep. Dopamine receptors improve cognition and also are effective at pain relieving. NA increase in brain facilitates pain inhibition. Clonidine is mainly a presynaptic agonist so helpful in reducing hyperarousal and promoting sleep. Pain reducing properties through reduction of amygdala hyperarousal and gaba pathways. It’s mild post synaptic activity also promotes sleep. Guanfacine is predominantly post synaptic alpha 2 - so main effects on cogntion. To some extent on pain ( but not used for this reason). As you can see in this regime to target adhd , sleep ( besides hyperarousal - dopamine is needed for REM sleep) and pain dopamine is missing along with increase in NA. So while Guanfacine and clonidine can be combined theoretically the rationale is not clear and therefore not commonly done. For adhd stimulants are first line to which either of these can be added as augmentation. If there are contraindications then other agents that increase DA and NA can be considered.

@@PsychiatrySimplified does tolerance occur in Guanfacine or Clonidine or Prazosin for that matter? If different for each, can you explain why? Should tolerance occur to these drugs, does the reset of the HPA axis from using alpha 2 drugs allow patient to come off drug without noticing the increased stress response of the upregulation of noradrenaline receptors ( should they occur in time from alpha drugs ) as cortisol now comes in to stop the CRF going on too long? Is the sign to cease the drug when missed doses show little withdrawal symptoms or during new onset of some type of chronic stress the patient has less chronic adrenaline type feeling without needing a dose increase? Is the morning blood cortisol result is in top third of normal range in patients usually on bottom of range an indicator to cease the alpha drug too as hpa axis has been reset by then?

@@jocs8824 Tolerance based on neuroscientific definition linked to addiction does not occur. Medications may stop providing benefits. This is usually because other mechanisms are at play. Tolerance is caused by adaptations leading to reduced sensitivity of neurotransmission systems targeted by particular drugs to maintain a homeostatic balance. Withdrawal symptoms are associated with these neuroadaptations. With clonidine etc increased doses will have an effect but side effects are more likely. Clinical symptoms are best gauge to reduction or cessation. Sudden cessation of medications alpha-blockers can result in rebound Sx, rebound REM sleep (heightened NA tone) etc. Early relapse signs are a better gauge than biomarkers. both short and long-term Sx have to be evaluated.

If cortisol turns off the noradrenaline and that reduces the loop of constant CRF/NE then why wouldn't a course of hydrocortisone help reverse PTSD? tapered off carefully of course! In PTSD the alpha 2 drugs would drop cortisol further until the hps axis is reset so how does a patient cope with the lowered cortisol in the interim if there is inflammation? I realise hydrocortisone is not good for the gut long term but can PTSD be reversed within several months on hydrocortisone? There are studies showing quick intervention with hydrocortisone prevents first development of PTSD when one faces a single traumatic event such as car accident or natural disaster? What would the effect of hydrocortisone be as it is linked to causing depression if taken chronically or is this effect desired in PTSD as noradrenic tone is opposite in these conditions....?

Good question again - Because cortisol is only one part of the equation. While it may, in the short term, help to a certain extent with amygdala NA reduction, it does not provide a sustained effect; hence the studies show benefits in the prevention and consolidation of memories. When PTSD has developed, the PFC is involved to a greater extent. Here cognition and reward pathways involving DA have also been affected as the illness has progressed. Plus, steroid administration will lead to adaptation, side effects notwithstanding. While the NA effect is increased in limbic pathways / endogenous levels of NA are low in synaptic cleft as the production cannot keep pace with release leading to an overall deficit. As long as this deficit is present, excess NA is released presynaptically (as the pre-synaptic feedback is affected). Hope this helps. this is why clonidine is used to activate pre-synaptic alpha 2 receptors. Hope this makes sense. The pathophysiology is discussed in more detail here. psychscenehub.com/psychinsights/post-traumatic-stress-disorder/

In depression it is the HPA axis dysfunction that is a key issue. If amygdala is activated due to stress or anxiety then the constant hpa activation dysregulates it. Unless low cortisol is part of say Addison’s disease in which case it should be treated by an endocrinologist. Prazosin or clonidine are indicated to reduce the hyperarousal so that this HPA axis can reset. The ‘low cortisol’ in trauma related aspects or depression is due to desensitisation of the receptors so they don’t respond to acth - which is the axis dysregulation. Treatment can assist .

There is evidence for a direct adrenergic regulation of penile veins, the predominant effect occurs through the alpha1- adrenoceptors but there remains the potential involvement of alpha2-adrenoceptors. Stimulation of the alpha2 -adrenoceptors in the cavernosal smooth muscle is known to be involved in erectile dysfunction. The predominant effect occurs through the alpha1-adrenoceptors but there remains the potential involvement of alpha2-adrenoceptors. Guanfacine is a alpha 2 agonist .

@@PsychiatrySimplified thanks for the info. Some have suggested a switch to clonidine. But one doctor friend said if Guanfacine didn’t help adhd for you and gave you sexual dysfunction, clonidine likely wouldn’t be any better for adhd for you and likely would give you even worse sex side effect. (Plus they said it’s often much more sedating)

@@GeoffreyPilkington it depends on what symptoms one is trying to treat as part of adhd. Clondine is more pre synaptic so more calming but unlikely to have sexual side effects for this reason but cognitive benefits directly are less ( more due to better sleep) . Have stimulants not been considered ?

@@PsychiatrySimplified yes, I have lots to say re: stimulants. I went on Adderall ir in 2015 for adhd. My response was robust. It gave me 3 great years and 2 pretty good years. Started at 10 mg / day in 2015 and over 5 years gradually built it towards 60 mg / day. (30 in morning, 30 in afternoon) however in the last 2 years the effect had faded somewhat. (One error was I was taking 1000 mg of vitamin C and drinking fruit juice all day the last 2 years which I found out just recently can have a big effect.) However just know I have / had a terrific initial response to the amphetamines which lasted me a period of years with just a little dry mouth at times being the only side effect. They helped me focus, they gave me more empathy, I was way more motivated, I listened way better, people seemed way less boring. The drug changed my life for the better. Anyway, my psychiatrist tried adderall xr and Concerta in 2021 when the adderall ir was fading (neither of which I responded to)… he didn’t want to prescribe me a higher dose than 60 mg per day of adderall ir. Dunno why. Fyi My bp is good. It IS a bit elevated at times. But not high. I’ve had that since 2005. My dads was always a little elevated. Most of the time it’s normal though. he also tried me on Zoloft, Luvox, and Trintellix from October 2021 to March 2022(2 months each) for some “mild depression”. All Zoloft and Luvox did was give me sexual dysfunction and fatigue. 2 months each. They didn’t help me at all. Trintellix had no side effects and also did nothing for me. I was later told in a 2nd opinion that I don’t have depression. (I Never thought I did so the antidepressants were a complete misfire and waste of time) Recently he moved me to Vyvanse 60 mg / day and it’s less Effective than the adderall jr. (However I’ve read it’s 1/3 the amount of dex however it’s metabolized more efficiently so it’s roughly half of what adderall ir is.) The only time I noticed Vyvanse working (I’ve been on it a month) was when I took TWO 60 mg of Vyvanse in one day. One in the morning and one in afternoon. This may be a clue that with the amphetamines it may be a dosage issue with me. He did up the dose of Vyvanse last week to 70 mg / day but it’s not doing anything. (Unless I take 2 in one day then I’m sure it’d be great) Coincidentally I start with a new psychiatrist tomorrow. It was time for a change and a fresh start. Any thoughts or advice? I’m a bit of a puzzle. It’s clear the amphetamines are the class of drug my system likes and Responds to however for whatever reason my previous doctor just couldn’t get the dosage right. I’m very frustrated obviously. Any advice appreciated. Thanks!

@@GeoffreyPilkington have a discussion with the doctor. Depends on age and specific symptoms. Ofcourse main aim is to get the cognitive aspects and then motivation in initial stages - d1 receptor stimulation which happens with high levels of dopamine but then the shift is towards the action areas - goal directed and habit areas of striatum where D1 receptors are situated - this happens through action , routine , specific goals and then d1 receptors get stimulated through unexpected rewards as we start putting plans in place for goals. Often if the medication is judged only on the ‘feeling aspect’ this wanes because of dopamine sensitisation in the reward pathway of liking ; this becomes the salience towards experiencing the pulsatile dopamine release. This may not be the case and it may be a dose issue but this a common issue that individuals come with - the group that has moved to action generally tend to have less of a ‘waning’ or need minor dose adjustments. Hence important to evaluate the key aims and symptoms. Wish you well
