How long does 10mg Propranolol last? (3 reasons why it may last longer) 

In this blog post, we are going to answer the question, “How long does 10mg Propranolol last?”. Propranolol is one of the most commonly prescribed beta-blockers which can be used to treat a variety of health conditions. 

This blog will cover the clinical significance of 10mg Propranolol and the time taken by this dose to get completely eliminated from your body. 

How long does 10mg Propranolol last?

10 mg Propranolol lasts for about a day or two. Propranolol has a half-life of about 3-6 hours, which means that the concentration of 10 mg Propranolol is reduced to half, that is 5 mg, after this time period. 

The remaining 5 mg of Propranolol is then further reduced to half (2.5 mg) after the next 3 to 6 hours. This process keeps on going until Propranolol is completely removed from your system. 

Can Propranolol last longer than the usual time? 

Yes, Propranolol can last longer if there are some factors present that are capable of hindering drug metabolism and excretion. These factors include:

  • Delayed gastric emptying rate can affect the stay time of Propranolol in your system. 
  • Some underlying or undiagnosed health conditions can affect the stay time of Propranolol in your system, especially kidney and liver diseases. 
  • Age is also an important factor that can affect the stay time of Propranolol in your system. 

All these factors are important and should be monitored before determining the appropriate dose. If your gastric emptying rate is decreased, the drug remains in your stomach for a longer period of time. This means that the high amount of drug gets absorbed in your system and it may give you more pronounced effects. 

Some underlying or undiagnosed health conditions can affect the stay time of Propranolol in your system. Most drugs, when taken orally, undergo first pass metabolism in the liver in which liver enzymes metabolise the drug and convert it into its inactive metabolites. 

These metabolites are then eliminated via urine. Some drugs are also eliminated unchanged through urinary excretion. However, if there is some disease that affects liver or kidney function, the entire process of drug metabolism and excretion is delayed. 

Under such circumstances, Propranolol may stay in your system for much longer than a day or two. As long as the drug stays, it somehow keeps affecting your body. This is exactly why most healthcare providers adjust the dose of meds for people who either have renal or hepatic insufficiency. 

Age is also a concern. When we grow old, all of our physiological systems grow old with us. This means that our organs don’t work as well as they used to when we are in our adult ages. 

This is why the doses of meds for geriatric population are also adjusted to make sure they won’t suffer from drug toxicity, as meds tend to stay longer in elderly people. Such people also have compromised liver and kidney function which can also affect the stay time of Propranolol. 

Why should you never stop Propranolol abruptly? 

Propranolol is associated with disturbing withdrawal symptoms, and most of those symptoms are cardiac-related. If you discontinue using this med suddenly, you may suffer from some of the symptoms. 

However, it varies greatly from person to person. Some people may not feel much, while others may get affected severely. It totally depends on how sensitive you are. It may not affect people with shorter duration of treatment that much, but people who have been using Propranolol for a while are more dependent on the medication. 

It is a known fact that whenever you start taking Propranolol or any other medication, it’s new for your body. Your body is not used to this foreign agent that can make chemical changes in it. This is why your body may take some time to adjust to the new med. 

Once it does, it starts considering the medication as a part of its system. This is how your body becomes dependent on the medication for the type of effects it produces. In the case of Propranolol, the drug keeps your heartbeat and blood pressure normal. 

If you continue to use it for a longer period of time, your body starts depending on it for normal cardiac functions. If we talk about withdrawal symptoms, they are basically cardiac-related symptoms and may become extremely serious for a cardiac patient with an active disease. 

Some of the withdrawal symptoms include:

  • Abnormally high blood pressure
  • Worsen angina
  • Chest pain
  • Increased risk of myocardial infarction (heart attack)
  • Severe lightheadedness
  • Irritability 
  • Anxiety and agitation 

These symptoms, as stated earlier, can be nerve-racking for some people. Propranolol is known to have anxiolytic effects as well, which means the drug can actively control your anxiety. When you stop it suddenly, you may feel your anxiety levels getting higher and higher. 

Make sure you stick to your medication if you wish to achieve your therapeutic goals. If you feel you have been impacted negatively by the drug, then consult your healthcare provider as soon as you can and discuss the safety and efficacy of Propranolol in your case. 

What is the clinical significance of 10mg Propranolol? 

Propranolol is a beta blockers or beta-adrenergic blocker. It is a drug which blocks beta receptors present in the heart and lungs and inhibits the effects of adrenaline, also known as epinephrine. 

It can also dilate blood vessels and decrease the workload of the heart. Propranolol can be used for the treatment of following health conditions:

Cardiovascular diseases

Propranolol are well known for its benefits in patients suffering from different cardiovascular diseases including:

  • High blood pressure 
  • Angina pectoris
  • Management of congestive heart failure 
  • Arrhythmia or irregular heart beat
  • Myocardial infarction 
  • Tachycardia 
  • Coronary artery diseases 

Glaucoma

Propranolol is given in the form of eye drops to help release some pressure by causing vasodilation. Glaucoma is an ocular disease which is associated with increased intraocular pressure. If left untreated, it may cause blindness.

Migraine

Propranolol can also be used as part of a first line treatment regimen to help relieve the painful symptoms of migraine. Various studies have revealed that Propranolol can significantly reduce the frequency of migraine attacks and the severity of headache.

Anxiety 

Propranolol can be used to help relieve the physical symptoms of anxiety by blocking stress hormones, but this is considered an off-label use and is not approved by the Food and Drug Administration (FDA) yet. 

Researchers are still weighing its pros and cons to be officially used as an anxiolytic. 

Essential tremors

Propranolol can also be used to treat tremors. It is medically approved to treat tremors. Studies show that people have actually gained relief from tremors after using Propranolol but it still can not provide complete relief. 

It can be taken once or twice a day, as suggested by your healthcare professional. 

Propranolol may also be used for some other reasons which are not mentioned here. One important thing to bear in mind is that this is a prescription medication and it should not be used without your doctor’s recommendation. 

Improper and unnecessary use of medications lead to a lot of nerve-racking complications. It is also not recommended to stop using Propranolol without your doctor’s approval. It may subject you to disturbing withdrawal symptoms. 

Conclusion 

In this blog post, we have discussed the stay time of 10mg Propranolol in your system. We have learned that 10 mg Propranolol lasts for about a day or two. Propranolol has a half-life of about 3-6 hours, which means that the concentration of 10 mg Propranolol is reduced to half, that is 5 mg, after this time period. 

The remaining 5 mg of Propranolol is then further reduced to half (2.5 mg) after the next 3 to 6 hours. This process keeps on going until Propranolol is completely removed from your system.
