Beta Blockers (Inderal, Propranolol, Atenolol) For Anxiety

Beta blockers are often used off label for anxiety disorder, particularly things like social anxiety disorder, because they're good medications that take away the symptoms of anxiety. Beta Blockers are good to take away the racing heart, the sweating, and the high blood pressure symptoms of anxiety. Beta Blockers have been used for quite awhile to treat anxiety this is because they work quickly and can be used as needed. You can use them for certain situations. You can use them if you're giving a speech, or if you're going to a social event, or if you're going on a date, whatever the case may be. This is something that you can take beforehand and it can take away those anxiety symptoms. The most commonly used beta blocker for anxiety is called inderal or propranolol. This one is used very often because it's shown to work best as a short term treatment for specific types of anxiety. Tenorman is also used quite a bit, it’s also known as atenolol. 


One really good thing about beta blockers is that they can be used to break you out of the cycle of a panic. If somebody's having a panic attack, you can take the beta blocker and it takes away that rising heart rate, high blood pressure, sweating, and allows you to break out of that cycle. It allows you to have your body calmed down enough that you yourself can regain control of your thoughts and your mind and be able to reorient yourself and bring yourself back to reality. Your anxiety may begin to seem unrealistic and you'll begin to recover. 


Beta Blockers actually hold several benefits over other anxiety medications, such as benzodiazepines. Benzodiazepines are a class of medications that include Xanax, Ativan, Valium or Klonopin. Benzodiazepines come with a lot of risk. One of them being that you can become tolerant and addicted to them. They are schedule IV controlled substances whereas beta blockers are not controlled substances, so you don't have to worry about becoming addicted to them, at least physically. 


Benzodiazepines have also been linked to some serious long term side effects such as dementia and mental decline. Benzodiazepines are something that a lot of physicians are really trying to get away from, and for very good reason. Often you will see beta blockers prescribed for anxiety before you see something like a benzo prescribed these days. 


There was a time in my mental health journey where I took a beta blocker, I took Propranolol, also called Inderal. I took it for a short amount of time because when I would take it, it didn't work for me, it really didn't help. It didn't take away any symptoms, which can be the case sometimes with medications, they just don't work right for you. Now, I do believe that I could have tried other beta blockers because they're chemically similar, but they're not the same. So I may have done better on a different one, but I never really got around to trying it. 


My doctor and I ended up trying different classes of medication instead. Beta Blockers are something that could be an option if you're struggling with anxiety, particularly something like social anxiety disorder. Ask your physician about this medication if it's something you think might work for you and might benefit you.

Reboxetine: The Forgotten Antidepressant Worth A Second Look

January 17, 2025

 

What is Reboxetine?

Reboxetine is a selective norepinephrine reuptake inhibitor (SNRI) medication used to treat depression and other mood disorders. It belongs to a class of drugs called norepinephrine reuptake inhibitors, which work by increasing the availability of the neurotransmitter norepinephrine in the brain.

Reboxetine is sold under various brand names, including Edronax, Norebox, and Davedax, among others. It is available in tablet form and is typically taken once or twice daily, with or without food.


History of Reboxetine

Reboxetine was developed in the late 1980s by the Danish pharmaceutical company Ferrosan (later acquired by Lundbeck). It was originally intended for the treatment of depression and other related disorders. The medication received its first approval in 1997 in the United Kingdom and several other European countries.

In the following years, reboxetine gained approval in various other nations across Europe, Latin America, and Asia-Pacific regions. However, it was never approved for use in the United States by the Food and Drug Administration (FDA) due to concerns over its safety and efficacy profile compared to other available antidepressants.

The timeline of reboxetine's development and approvals is as follows:

- Late 1980s: Initial development by Ferrosan

- 1997: First approved in the UK and other European countries

- 1999: Approved in Mexico

- 2000: Approved in several Asian countries like India, Malaysia, and Thailand

- 2001: Approved in Brazil and Argentina

- 2007: Approval withdrawn in the UK due to safety concerns

- Present day: Still marketed in various countries, but not widely used due to availability of newer antidepressants

Despite its initial promise, reboxetine's use has declined over the years, as newer and potentially more effective antidepressant medications have emerged in the market.


Mechanism of Action

Reboxetine is a selective norepinephrine reuptake inhibitor (SNRI), which means it works by blocking the reuptake of the neurotransmitter norepinephrine in the brain. Norepinephrine is a chemical messenger that plays a crucial role in regulating mood, attention, and arousal.

When norepinephrine is released from nerve cells, it transmits signals to other neurons, helping to regulate various brain functions. However, after performing its function, norepinephrine is typically reabsorbed (or "reuptaken") by the nerve cells that released it, effectively terminating its effects.

Reboxetine works by preventing this reuptake process, allowing norepinephrine to remain active in the synaptic cleft (the space between neurons) for a longer period. This increased availability of norepinephrine enhances the neurotransmitter's effects on the brain, which can help alleviate symptoms of depression.

Unlike other antidepressants that target both norepinephrine and serotonin (another neurotransmitter involved in mood regulation), reboxetine is highly selective for norepinephrine reuptake inhibition. This selective action on the norepinephrine system is thought to contribute to its unique therapeutic profile and potential benefits in treating depression.


Evidence for Use in Depression

Reboxetine has been extensively studied in clinical trials for its efficacy in treating major depressive disorder. Several large-scale, randomized, double-blind, placebo-controlled studies have demonstrated the antidepressant effects of reboxetine.

In one pivotal study involving over 800 patients with major depression, reboxetine significantly outperformed placebo in reducing symptoms of depression, as measured by the Hamilton Depression Rating Scale (HAM-D) and other assessment tools. The response and remission rates were significantly higher in the reboxetine group compared to the placebo group.

Another multicenter trial involving over 1,000 patients with severe depression found that reboxetine was superior to placebo in alleviating depressive symptoms, with a higher proportion of patients achieving remission after 8 weeks of treatment.

Reboxetine has also been studied in specific subgroups of patients with depression, such as elderly individuals and patients with comorbid medical conditions. The results have generally shown that reboxetine is effective and well-tolerated in these populations.

Based on the collective evidence from clinical trials, reboxetine is approved in several countries for the treatment of major depressive disorder. It is considered an effective and well-tolerated antidepressant option, particularly for patients who may not respond well to or cannot tolerate other classes of antidepressants.


Benefits vs Other Antidepressants

Reboxetine offers some potential advantages over other commonly prescribed antidepressants, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). One key benefit is its mechanism of action, which selectively inhibits the reuptake of norepinephrine, a neurotransmitter involved in regulating mood, attention, and energy levels.

Unlike SSRIs and SNRIs, which primarily target serotonin or a combination of serotonin and norepinephrine, reboxetine's selective norepinephrine reuptake inhibition may provide a unique therapeutic profile. This could make it an effective alternative for individuals who have not responded well to other antidepressants or who experience specific side effects with those medications.

In terms of efficacy, research suggests that reboxetine may be comparable to SSRIs and SNRIs in treating depression. However, some studies indicate that reboxetine may have a faster onset of action, with improvements in depressive symptoms observed within the first two weeks of treatment.

Regarding side effects, reboxetine may have a different side effect profile compared to SSRIs and SNRIs. It is generally associated with fewer sexual side effects, such as decreased libido or erectile dysfunction, which are common with SSRIs and SNRIs. Additionally, reboxetine may be less likely to cause weight gain, a frequent complaint with some other antidepressants.

However, reboxetine has its own set of potential side effects, including dry mouth, constipation, increased blood pressure, and insomnia. It is important to weigh the potential benefits and risks with a healthcare provider when considering reboxetine or any other antidepressant medication.


Dosing of Reboxetine

Reboxetine is typically started at a low dose of 4 mg once daily, taken in the morning. The dose can then be gradually increased based on individual response and tolerability. The recommended therapeutic dosage range is 8-10 mg per day, with a maximum daily dose of 12 mg.

It's important to follow the prescribed dosing schedule and not exceed the recommended maximum dose. Dosage adjustments may be necessary for elderly patients or those with renal or hepatic impairment, as they may require lower doses.

When discontinuing reboxetine, it's advisable to gradually taper the dose over a period of at least one to two weeks to minimize the risk of withdrawal symptoms. Abrupt discontinuation should be avoided.


Side Effects and Adverse Reactions

Common Side Effects:

Like many antidepressants, Reboxetine can cause several common side effects, including:

- Dry mouth

- Constipation

- Nausea

- Dizziness

- Insomnia or difficulty sleeping

- Headaches

- Increased sweating

- Loss of appetite

These side effects are typically mild and may subside after a few weeks as your body adjusts to the medication.

Serious Adverse Effects:

While rare, Reboxetine can also cause more severe adverse reactions, such as:

- Suicidal thoughts or behaviors, especially in young adults

- Manic episodes or increased risk of bipolar disorder

- Serotonin syndrome (a potentially life-threatening condition caused by high serotonin levels)

- Abnormal bleeding or bruising

- Seizures

- Glaucoma or increased intraocular pressure

It's crucial to seek immediate medical attention if you experience any of these severe side effects.

Contraindications:

Reboxetine should not be taken by individuals with certain medical conditions or those taking specific medications due to potential interactions or increased risks. Contraindications include:

- History of bipolar disorder or manic episodes

- Severe liver or kidney disease

- Concurrent use of monoamine oxidase inhibitors (MAOIs)

- Pregnancy or breastfeeding (consult with your doctor)

Your healthcare provider will carefully evaluate your medical history and current medications before prescribing Reboxetine to ensure it is safe for you.


Positives and Pros of Reboxetine

Reboxetine offers several potential benefits and advantages over other antidepressant medications:

- Effective for Treating Depression: Numerous clinical studies have demonstrated reboxetine's efficacy in alleviating symptoms of major depressive disorder (MDD). It can help improve mood, increase energy levels, and restore interest in daily activities.

- Faster Onset of Action: Compared to some other antidepressants, reboxetine may have a slightly faster onset of action, with some patients reporting improvements in their symptoms within the first two weeks of treatment.

- Minimal Impact on Sexual Function: Unlike many other antidepressants, reboxetine is less likely to cause sexual side effects, such as decreased libido, erectile dysfunction, or difficulty achieving orgasm. This can be a significant advantage for patients who are concerned about the impact of medication on their sexual health.

- No Weight Gain: Reboxetine is generally weight-neutral, meaning it is unlikely to cause significant weight gain or weight loss. This can be beneficial for patients who are concerned about the metabolic effects of certain antidepressants.

- Fewer Discontinuation Symptoms: When stopping reboxetine, patients may experience fewer or milder discontinuation symptoms (e.g., dizziness, nausea, or flu-like symptoms) compared to some other antidepressants, such as selective serotonin reuptake inhibitors (SSRIs).

- Potential Cognitive Benefits: Some studies suggest that reboxetine may have positive effects on cognitive functions, such as attention, memory, and executive function, which can be impaired in individuals with depression.

- Potential Neuroprotective Effects: Preclinical research indicates that reboxetine may have neuroprotective properties, potentially helping to preserve or regenerate brain cells and neural pathways affected by depression.

By understanding these potential benefits and advantages, patients can make an informed decision about whether reboxetine may be a suitable treatment option for their specific needs and circumstances.


Negatives and Cons of Reboxetine

Reboxetine has several potential downsides and cons that should be considered before starting treatment. One of the main concerns is its side effect profile, which can be more pronounced compared to some other antidepressant medications.

Reboxetine has been associated with an increased risk of adverse effects, such as dry mouth, constipation, sweating, insomnia, and dizziness. These side effects can be particularly bothersome and may lead to poor medication adherence or discontinuation of treatment.

Another significant drawback of reboxetine is its potential for drug interactions. Reboxetine can interact with various medications, including certain antidepressants, antipsychotics, and medications used to treat high blood pressure or heart conditions. These interactions can increase the risk of adverse effects or reduce the effectiveness of the medications involved.

Furthermore, reboxetine has been linked to a higher risk of cardiovascular side effects, such as increased blood pressure and heart rate. This risk may be particularly concerning for individuals with pre-existing cardiovascular conditions or those at risk for developing cardiovascular problems.

Additionally, reboxetine has a relatively narrow therapeutic window, meaning that the dosage range between an effective dose and a potentially toxic dose is relatively small. This can make it challenging to find the optimal dosage for each individual patient, increasing the risk of adverse effects or suboptimal treatment response.

It's also worth noting that reboxetine has a higher risk of discontinuation syndrome compared to some other antidepressants. This syndrome can occur when the medication is abruptly stopped or the dosage is reduced too quickly, leading to withdrawal symptoms such as dizziness, nausea, and mood disturbances.

Finally, reboxetine may not be as effective as some other antidepressant medications in treating severe or treatment-resistant depression. In some cases, it may be necessary to try alternative medications or combination therapies to achieve an adequate response.


Conclusion

Reboxetine is a unique antidepressant medication that works by selectively inhibiting the reuptake of norepinephrine, a neurotransmitter involved in mood regulation and stress response. While it may not be as widely used as some other antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), reboxetine has shown promising efficacy in treating major depressive disorder and can be a valuable option for patients who do not respond well to or cannot tolerate other types of antidepressants.

The key advantages of reboxetine include its targeted mechanism of action, which may be particularly beneficial for individuals with certain subtypes of depression, such as those with prominent symptoms of fatigue, lack of motivation, or concentration difficulties. Additionally, reboxetine has a relatively low risk of certain side effects commonly associated with SSRIs, such as sexual dysfunction or weight gain.

However, it is important to carefully consider the potential side effects and contraindications of reboxetine, as well as its potential interactions with other medications. Patients should work closely with their healthcare providers to determine if reboxetine is an appropriate treatment option based on their individual circumstances and medical history.

Overall, reboxetine can be an effective and valuable treatment option for individuals struggling with depression, particularly when other antidepressants have been ineffective or poorly tolerated. As with any medication, it is crucial to weigh the potential benefits and risks and to closely follow the guidance of a qualified healthcare professional.
