Research testing a small dose of beta-blocker blood pressure medicine, Propranolol, has reported that it may help with pain symptoms in chronic pain patients.
Propranolol is a synthetic β-adrenergic receptor blocker that crosses the blood–brain barrier and exerts peripheral effects on the noradrenergic system as well as central (inhibitory) effects on protein synthesis. Protein synthesis is necessary to consolidate new learning to long-term memory storage.
System Side Effects of Beta BlockersOne of the attributes of beta-adrenergic blocking agents that has distinguished these drugs from each other is degree of lipophilicity.
Beta blockers can have a constricting effect on the bronchi of the lungs, possibly worsening or causing asthma symptoms. Since β2 adrenergic receptors can cause vascular smooth muscle dilation, beta blockers may cause some vasoconstriction.
The cardio-selective beta-blockers include atenolol, betaxolol, bisoprolol, esmolol, acebutolol, metoprolol, and nebivolol [1].
Beta blockers work mainly by slowing down the heart. They do this by blocking the action of hormones like adrenaline. Beta blockers usually come as tablets.
Figure 1: A schematic of various pathways crossing the BBB [9]. entry of agents into the brain is in many cases performed by crossing through the cellular membrane of the capillaries and through For instance, Polar drugs such as penicillin cannot easily enter the brain [11,12,13,14,15].
It is slowly and incompletely absorbed after intramuscular administration. It is highly lipid soluble and widely distributed throughout the body. Diazepam readily crosses the blood–brain barrier and is highly protein bound. Diazepam is metabolized in the liver.
These beta blocker drugs slow the heart rate and are used to treat patients with partly blocked coronary arteries or high blood pressure. The drugs can enter the brain where, it has been suggested, they can alter mood and mental performance as well as sexual performance.
Beta blockers, sometimes used for hypertension and heart irregularities, such as propranolol and atenolol. Statins can rarely cause brain fog, but on the other hand they lower high cholesterol that left untreated raises the risk of dementia.
When taken in very high doses, beta blockers can worsen heart failure, slow the heart rate too much, and produce wheezing and a worsening of lung disease. High doses may also cause lightheadedness from a drop in blood pressure, which puts people at risk for falls and injury.
A cardioselective beta-blocker such as bisoprolol or metoprolol succinate will provide the maximum effect with the minimum amount of adverse effects. Beta-blockers that reduce resting heart rate less than others (due to ISA) tend not to be used for angina, e.g. celiprolol and pindolol.
Do not stop taking a beta blocker suddenly without consulting your doctor. This is important because when you take a beta blocker regularly, your body becomes used to it. Stopping it suddenly could cause problems such as palpitations, a recurrence of angina pain or a rise in blood pressure.
If you stop beta-blockers abruptly, your blood pressure may go up suddenly and you may get irregular heart rhythms (palpitations). If you take beta-blockers to treat angina (chest pain), stopping your medicine abruptly could make your chest pain worse.
Guidelines recommend beta blocker therapy for three years, but that may not be necessary. Beta blockers work by blocking the effects of the hormone epinephrine, also called adrenaline. Taking beta blockers reduces your heart rate and blood pressure. This eases the workload on your heart and improves blood flow.
Most people who take beta blockers do well and have no side effects. Since beta blockers slow your heart, you may feel more tired. Exercise may seem harder than before. For example, you may get out of breath when you take a walk or climb stairs.
But they can cause fatigue and depression in some people, as well as other side effects, such as erectile dysfunction. For decades, beta blockers have also been prescribed routinely to heart attack survivors, based on early studies suggesting that these drugs improved survival.
Cardioselective. A number of beta blockers, including atenolol (Tenormin) and metoprolol (Toprol, Lopressor), were designed to block only beta-1 receptors in heart cells. Since they don't affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders.
Too much potassium can lead to erratic heart rhythm and kidney failure. If you are taking a beta-blocker, your health care provider may recommend that you limit your consumption of bananas and other high potassium foods including papaya, tomato, avocado and kale.
While taking beta-blockers, avoid products with caffeine and alcohol. Don't take cold medicines, antihistamines, or antacids that have aluminum in them. Mayo Clinic: "High blood pressure (hypertension): Beta blockers." American Heart Association: "Types of Blood Pressure Medications."
Beta-
blockers stop the effects of epinephrine (adrenaline), and this causes the heart to beat slower and lowers your blood pressure. Some foods, herbs, and supplements can also act as

As seen in figure 1, the most commonly prescribed beta-blocker medications are metoprolol succinate and metoprolol tartrate.
Beta-blockers slow your heart rate. As a result, you may notice that you feel more tired. You may also feel like you can't exercise as hard as you used to. Beta-blockers can decrease your sex drive.
Its job is to respond to adrenaline, one of the body's key stress hormones. Adrenaline, acting through beta adrenergic receptors, makes the heart beat faster and harder. This increases blood pressure. By acting as a kind of anti-adrenaline, beta blockers slow the heart's rate and ease the force of its contractions.
Even among patients on beta-blockers, the proportion with HR≥70 bpm was 41.1%. Also, among patients with anginal symptoms, only 22.1% achieved a HR≤60 bpm, despite the fact that stable angina guidelines recommend a target HR of 55–60 bpm in patients with angina on beta-blockers [22].
Reaction time, concentration, and visual and verbal memory were not impaired by either beta blocker. The drugs' anxiolytic effects may have been responsible for improved performance on a test measuring visual motor tracking and memory. An association between beta blockers and depression was not detected.
W hat we show is that in hypertension, when you slow down the heart rate with a beta blocker, it actually shortens your life.
The Mini–Mental State Examination (MMSE) or Folstein test is a 30-point questionnaire that is used extensively in clinical and research settings to measure cognitive impairment. It is commonly used in medicine and allied health to screen for dementia.
Drinking alcohol while you're taking beta-blockers generally isn't recommended by doctors. Beta-blockers lower your blood pressure by slowing your heart rate and reducing the force of each beat. Alcohol can also lower your blood pressure.
Stress, anxiety or depression can cause forgetfulness, confusion, difficulty concentrating and other problems that disrupt daily activities. Alcoholism. Chronic alcoholism can seriously impair mental abilities. Alcohol can also cause memory loss by interacting with medications.
Caution!These 10 Drugs Can Cause Memory Loss
- Antianxiety drugs (Benzodiazepines)
- Cholesterol-lowering drugs (Statins)
- Antiseizure drugs.
- Antidepressant drugs (Tricyclic antidepressants)
- Narcotic painkillers.
- Parkinson's drugs (Dopamine agonists)
- Hypertension drugs (Beta-blockers)
- Sleeping aids (Nonbenzodiazepine sedative-hypnotics)
In addition to its effects through conversion of angiotensin II to IV and other mechanisms that have been shown in previous studies, losartan can improve and enhance memory and learning performances by improving leptin resistance and facilitating leptin beneficial actions on CNS and memory enhancement.
Long-term memory loss is when you have trouble recalling this information when you need it. Many people's long-term memory starts to get weaker as they get older. This is a normal part of aging. Existing between normal age-related memory changes and dementia is the condition known as mild cognitive impairment (MCI).
Anticholinergics from the following groups increased dementia risk when used at the highest doses:
- antidepressants OR 1.29 (95% CI 1.24 to 1.34)
- anti-Parkinson's drugs OR 1.52 (95% CI 1.16 to 2.00)
- antipsychotics OR 1.70 (95% CI 1.53 to 1.90)
- anti-epileptics OR 1.39 (95% CI 1.22 to 1.57)
There are two main risks to exercising after taking beta-blockers: dehydration, and over-exertion. Dehydration is characterized by: Excessive thirst. Fatigue.
