Beta-Rezeptoren-Blocker werden vor allem bei der Behandlung von Herzerkrankungen, aber auch bei Hyperthyreose.

Diligent blood glucose level monitoring is necessary for a patient with diabetes mellitus on beta-blocker.

Though beta-blockers can be useful to manage acute symptoms in thyrotoxic patients to reduce tachycardia, tremor, and anxiety, beta-blockers should be used with caution as tachycardia is a useful monitoring parameter in thyroid disease.

Abrupt withdrawal can result in thyroid storm. Unless a pacemaker is present, beta-blockers can severely depress conduction in the AV node, resulting in reduction of heart rate and cardiac output.

Usage of beta-blockers in tachycardic patients with Wolff-Parkinson-White Syndrome can result in severe bradycardia, necessitating treatment with a pacemaker.

Glucagon , used in the treatment of overdose, [59] [60] increases the strength of heart contractions, increases intracellular cAMP , and decreases renal vascular resistance.

It is, therefore, useful in patients with beta blocker cardiotoxicity. Other antidotes for beta blocker poisoning are salbutamol and isoprenaline.

Beta blockers inhibit these normal epinephrine- and norepinephrine-mediated sympathetic actions, [3] but have minimal effect on resting subjects.

Beta blockers can have a constricting effect on the bronchi of the lungs, possibly worsening or causing asthma symptoms. By far the greatest effect of beta blockers remains in the heart.

Newer, third-generation beta blockers can cause vasodilation through blockade of alpha-adrenergic receptors. Accordingly, nonselective beta blockers are expected to have antihypertensive effects.

Antianginal effects result from negative chronotropic and inotropic effects, which decrease cardiac workload and oxygen demand.

Negative chronotropic properties of beta blockers allow the lifesaving property of heart rate control. Beta blockers are readily titrated to optimal rate control in many pathologic states.

The antiarrhythmic effects of beta blockers arise from sympathetic nervous system blockade—resulting in depression of sinus node function and atrioventricular node conduction, and prolonged atrial refractory periods.

Sotalol , in particular, has additional antiarrhythmic properties and prolongs action potential duration through potassium channel blockade.

Blockade of the sympathetic nervous system on renin release leads to reduced aldosterone via the renin—angiotensin—aldosterone system , with a resultant decrease in blood pressure due to decreased sodium and water retention.

Also referred to as intrinsic sympathomimetic effect, this term is used particularly with beta blockers that can show both agonism and antagonism at a given beta receptor, depending on the concentration of the agent beta blocker and the concentration of the antagonized agent usually an endogenous compound, such as norepinephrine.

See partial agonist for a more general description. Some beta blockers e. These agents, therefore, may be useful in individuals exhibiting excessive bradycardia with sustained beta blocker therapy.

Agents with ISA are not used after myocardial infarctions, as they have not been demonstrated to be beneficial. They may also be less effective than other beta blockers in the management of angina and tachyarrhythmia.

Beta blockers, due to their antagonism at beta-1 adrenergic receptors, inhibit both the synthesis of new melatonin and its secretion by the pineal gland.

The neuropsychiatric side effects of some beta blockers e. Some pre-clinical and clinical research suggests that some beta blockers may be beneficial for cancer treatment.

Beta blockers have also been used for the treatment of schizoid personality disorder. Contrast media are not contraindicated in patients receiving beta blockers.

No personal information is collected about our users. This service is used entirely anonymously. We do not collect email addresses, phone numbers, names or any other information that could be used to identify our users.

We understand that gambling addiction can be an embarrassing thing to confront. While we are happy to help you we do not need to know who you are.

How do I reset my password if I forget it? Unfortunately there is no way to reset your password after a Forever Self-Exclusion has been activated.

BetBlocker is paid for by a group that market online gambling services. It would be entirely unethical for such a group to gather contact information for users of a tool of this nature.

Given that BetBlocker users are specifically looking for help to control or stop their gambling, at no point should they ever be exposed to anything that would give incentive to gamble because of their use of BetBlocker.

To allow users to reset their password we would need to gather email addresses from users. For the reasons defined above we cannot do that without being accused of using this service to create a marketing list of gamblers with addiction issues.

As such there is no facility to reset your password and it is imperative you keep it safe if you are ever likely to need it.

Do remember that the only user that would need a password is a user that selects to Self-Exclude Forever and subsequently wants to lift their Self-Exclusion after 5 years or Parental Control users and those restrictions will be automatically lifted at the end of the selected exclusion period.

How will BetBlocker impact my battery consumption? The results are detailed below. Please keep in mind that these are very general tests to give an idea of the impact.

Your experience may differ depending on other apps you have running on your phone, the make and model of your phone and the size of your battery.

Android mah battery size : 1. Active mode — Our testing shows that while BetBlocker is active and the phone is being constantly used to browse the internet and play games the battery life with was 14 hours.

Under the same conditions without BetBlocker active the battery life was 15 hours 30 minutes. Sleep mode - Our testing shows that while BetBlocker is active and the phone not being used is on but not actively doing anything the battery will drain in 96 hours.

Under the same conditions the battery life while BetBlocker was not active was 97 hours. Contacting Support. You can email us at admin betblocker.

That depends on a number of factors. Firstly understand that BetBlocker is not a commercial tool.

We will endeavour to respond to your request within 24 hours, but response times can vary depending on various factors, including the volumes of support requests we are receiving and the availability of a team member to respond.

As we receive regular contacts from users simply looking to request that we add a url to the restriction list or to thank us for the app, we try our best not to gather any information on those users.

That does mean however that if you need a response you need to tell us where to respond to. Technical Issues. With the millions of possible combinations of software and hardware that are in use today, from time to time some users will experience technical issues with BetBlocker.

While we will be more than happy to have our Development Team investigate your issue and provide a solution as quickly as possible, this may take some time.

We will not remove the app unless there is no other way of resolving your issue. For people with compulsive tendencies related to gambling being able to access online gambling services has the potential to cause extensive damage to their lives in a short space of time.

Ultimately, based on the primary function of our tool, our priority has to be restricting access to gambling services first and foremost.

Does that mean that from time to time some users will be frustrated when they are impacted by a bug that takes some time for us to resolve?

But we have to make a judgement as to what is the lesser evil: leaving these users frustrated while we resolve the issue or exposing them to gambling services that have the potential to cause vast damage to their lives.

There's no good choice to make in these circumstances but it is better to cause some frustration than to potentially take actions that could result in someone inflicting significant damage on their life.

The severity of the user's problem isn't something that we have any scope to make an assessment of. We have to treat every user's issues as serious regardless of what they say while trying to get the service removed.

We do not like or want to cause any user frustration, but we do ask that you understand that causing frustration is the lower risk option and far preferable to someone ultimately losing money they cannot afford to lose because we tried to keep them happy in the short term rather than made the difficult choice.

Local Network. BetBlocker uses a VPN to enforce your gambling restriction. While there are some intricacies in the specific set-up, for the purpose of 'local networks' your device will appear to be accessing from our VPN server.

As such you will not be recognised as part of the local network and will not be able to access it. When you set a Gambling Self-Restriction in BetBlocker the tool will automatically restrict you device from accessing any of the gambling operator URLs in our database.

We update this database on a weekly basis to ensure that you are offered the maximum possible protection.

Can I remove a Gambling Self-Restriction after it has started? Gambling addiction is a condition that is commonly associated with an inability to control ones impulses to wager.

That being the case this tool would be ineffective at preventing gambling relapses if you could disable it during a Gambling Self-Restriction.

As such, once a Gambling Self-Restriction has been activated it cannot be lifted. Even uninstalling the tool or deleting the files associated with the tool will not lift the restriction.

Once you have activated a Gambling Self-Restriction the only way to end it is to wait until your chosen Gambling Self-Restriction period has concluded.

For ethical reasons and the protection of problem gamblers our support team will not under any circumstances assist a user to disable an active Gambling Self-Restriction.

How long can I Self-Restriction for? There are a wide range of Gambling Self-Restriction options available when activating a Self-Restriction.

Currently we offer 24h, 2 days, 3 days, 5 days, 1 week, 2 weeks, 1 month, 2 months, 3 months, 6 months, 1 year, 2 years, 3 years, 5 years or forever.

Can I extend my Gambling Self-Restriction? This will be implemented immediately. Can I exclude from sites other than gambling operators?

While setting up a Gambling Self-Restriction our full list of gambling operators will always be included see our Parental Controls setting for options without restricting online gambling websites.

However you can choose to include other sites in your restrictions. We include an optional list of gambling information and advertisement sites that can be included in your Gambling Self-Restriction this includes being able to exclude yourself from the service that funds BetBlocker and allow you to include custom URLs so that you can include any site not on our list in your Gambling Self-Restriction.

Will my Gambling Self-Restriction automatically be lifted at the end of my selected exclusion period?

This depends on the length of exclusion you select: - If you select 24h, 2 days, 3 days, 5 days, 1 week, 2 weeks or 1 month the exclusion will be automatically lifted at the end of the period you selected.

If you request to deactivate the tool it will automatically continue of 1 week. At any point during the Cooling Off Period you can extend your Gambling Self-Restriction and the restriction will not end.

If you do not extend your Gambling Self-Restriction during the Cooling Off Period the restrictions will automatically be lifted at the end of the 1 week Cooling Off Period.

When setting up a Gambling Self-Restriction and selecting to be excluded Forever you will be required to set-up a password.

At the end of the 5 year period you will only be able to lift your Gambling Self-Restriction if you can enter the password you created when setting the exclusion up.

If you do look to lift this Gambling Self-Restriction after the 5 years and can enter in the correct password your exclusion will automatically continue for 1 week.

How do the restrictions BetBlocker offers compare with those required by the various online gambling regulatory bodies? The restrictions offered by BetBlocker represent the strongest restrictions required by a combination of the UK Gambling Commission and the Malta Gambling Authority: - As required by both regulatory authorities a Gambling Self-Restriction will automatically exclude you from all properties on a license and thousands of other operators - As required by the UKGC, once a Gambling Self-Restriction has been activated it cannot be lifted until the full term of the selected exclusion has been complete.

Someone else activated BetBlocker on my device. Can you remove it for me? While we understand that you may be frustrated if someone else has set up an exclusion on your behalf, we have no way of proving who specifically agreed to the terms of use.

Where someone has set-up BetBlocker on a device we have to assume that they either are the device owner or are authorised to set-up this restriction.

Can you remove BetBlocker for me? When activating BetBlocker you both agree to terms of use explicitly stating that you will not be able to remove this block until your restriction period has concluded.

This is also highlighted during the activation process.
