What is Tenormin

Atenolol

The Generic name of this drug

Treatment Summary

Atenolol is a type of medication used to treat various heart conditions. It was invented in 1958 by Scottish pharmacologist Sir James Black, who won the Nobel Prize for his work. Atenolol is usually prescribed for high blood pressure, heart attack, arrhythmias, and heart failure. However, studies have suggested that atenolol may not reduce mortality or cardiovascular disease in people with hypertension, and the risk of stroke may depend on the age of the patient. Therefore, atenolol should be used based on more than just hypertension.

How Tenormin Affects Patients

Atenolol is a drug that can help regulate the heart. It works by blocking certain hormones and nerves that control the heart rate, electrical conductivity, and contractility. This reduces the amount of work the heart needs to do, which can reduce the risk of angina or chest pain. It also helps to control the rate of electrical signals in the heart, which can help with arrhythmia (irregular heartbeat). Atenolol can also help lower blood pressure, though it is less effective than other beta blocker drugs. It may cause fatigue, depression, or sleep disturbances like nightmares or insomnia. It can also cause

How Tenormin works in the body

Atenolol is a type of drug that only affects certain parts of the body, called a cardioselective beta-blocker. It works by blocking the activity of special receptors in the heart and lungs called beta-1 receptors. When these receptors are blocked, the signals sent to the heart and lungs that cause them to work harder are stopped. This can slow down the heart rate and relax the muscles in the lungs, making it easier to breathe. In the heart, atenolol stops certain proteins from increasing the amount of calcium in the cells. This helps reduce the amount of contractions in the heart and keeps

Tenormin for Ventricular Rate Control in Atrial Fibrillation

I've been taking Tenormin for a while now and it does help to keep my blood pressure stable. However, I have developed an annoying cough that I haven't been able to shake. From what I understand, this is a common side-effect of the medication. Has anyone else experienced something similar?

Tenormin for High Blood Pressure

I started with a 100 mg dose, but my blood pressure went down to about 90/65. The doctor reduced my dosage to 50 mg a day and it has worked well for my blood pressure. My heart rate is high (120 to 90 bpm) and it did not affect that so I'm going to ask for a beta blocker like Sectral.

I took this drug for many years and saw some great benefits, like quitting smoking and drinking, and losing weight. Recently I complained of shortness of breath to my doctor, who then weaned me off the medication. As a result, I no longer have shortness of breath; in fact, a number of other issues I had before - like GERD and fatigue - got better. I would definitely recommend making lifestyle changes if you're able.

What are the side effects of Tenormin?

"The following are symptoms of the flu:

Dizziness

Lightheadedness

Tired feeling

Nausea

Slow heart rate

Depression

Decreased sex drive

Impotence"

Answered by AI

When should I take Tenormin?

"To take atenolol, you will typically take it once or twice a day. Your doctor may tell you to take your first dose before going to bed because it can make you feel dizzy. If you do not feel dizzy after the first dose, you can take the medicine in the morning."

Answered by AI

Is Tenormin a good drug?

"Atenolol (Tenormin) can help to relieve chest pain and angina. It may also reduce the risk of death if taken after a heart attack. Although it can be used to treat high blood pressure, it is not the preferred option and is usually only used if other medications have not been effective."

Answered by AI

What is Tenormin tablets used for?

"Atenolol is used to treat high blood pressure, either on its own or with other medications. By lowering high blood pressure, it can help prevent strokes, heart attacks and kidney problems. It is also used to treat chest pain (angina) and improve survival rates after a heart attack."

Heparin Dosing for Blood Clots and Heart Conditions

18+
All Sexes
Alexandria, VA

The goal of this clinical trial study is to test whether a mathematical calculation, using the patient's gender, weight and kidney function, can better predict a patient's heparin goal dose than a flat number of units per patient weight can. Participants will have the first dose of heparin infusion calculated, after which if adjustments are needed, the Hospital's prebuilt table for results driven dosing for this purpose is used. The researchers will compare the time it takes for the participants to get to the desired goal using the patient's information for calculation versus patients in the past who received the medication using the flat rate. The hypothesis is that the patients with enhanced personal data, gender, weight and kidney function, included for the initial dose, will get to their goal lab value sooner and with less chance of delay or overshooting the goal. A quicker time to goal lab value is beneficial to patients in many ways, including earlier treatment of the clot or coronary issue that the patient is experiencing.

Embolization for Migraine

18 - 80
All Sexes
Baltimore, MD

This study is to test the safety and feasibility of a procedure called embolization of the middle meningeal arteries (MMA), using a product called Onyx. Embolization creates a plug in the arteries. MMA embolization with Onyx is not approved for use in patients with migraines, but is currently used in patients with subdural hematomas. The FDA is allowing the use of Onyx in this study. It is thought that by using Onyx to block the middle meningeal arteries, the amount of migraine-causing substances which are released into the brain's bloodstream will be reduced. The company that manufactures Onyx, Medtronic, is providing the supplies for this study. Participants will be in the study for about 8 months after enrolling, including 6 months of follow up after the procedure. The participants will be asked to complete a daily headache diary and continue the participant's regular migraine medications. Participants will also have several clinic visits and be asked to provide blood samples for research.

Supportive Management for Heart Failure and Methamphetamine Addiction

18+
All Sexes
Los Angeles, CA

Heart failure (HF) affects over 6 million people in the US and is a major cause of both hospital admissions and death. HF has many causes and contributing factors. One of the most aggressive forms of HF is associated with methamphetamine abuse, which has become its own epidemic in the US over the past twenty years. People who use methamphetamine tend to develop HF at a much younger age, with more severe disease and more serious consequences. A recent analysis using nationwide data, methamphetamine use doubled the risk of death or hospitalizations compared to non-users in patients with HF. Thus, methamphetamine users with HF represent a very high-risk group of patients from a healthcare perspective. HF may be reversible in some patients who use methamphetamine if patients can achieve 1) abstain from further methamphetamine use and 2) consistently take all the medications that can improve HF. These two goals are very difficult to achieve in practice, as the care of both methamphetamine addiction and HF requires specialized medical expertise and intensive regular follow up of patients. In general, achievement of one goal is not possible without the other. Patients who use methamphetamine have poor adherence to medical follow-up and therapies, and abstinence from methamphetamine is difficult to maintain. This is further complicated because the current model of HF care does not incorporate treatment for methamphetamine use. The current study proposes to launch a multidisciplinary clinic that treats both HF and methamphetamine use disorder at the same time. The HF care will be led by a cardiologist while the methamphetamine use treatment will be led by a psychiatric clinical pharmacist trained in addiction medicine. State-of-the-art HF care will include optimization of four pillar HF medications. Methamphetamine use treatment will include counseling and incentivized abstinence known as contingency management (CM). The investigators will manage the patients in the clinic for 6 months total. The investigators are interested in demonstrating that this integrated clinic model will result in improved delivery of care for these patients by reporting the rates of successful abstinence from methamphetamine, improved optimization of the four HF medications, and enhanced patient reported quality of life over the 6 months of follow up. The investigators will also collect data on the costs associated with providing this level of care and estimate a range of potential cost-savings.
