What is the drug adenosine used for?
ADENOSINE (a DEN uh seen) is used to bring your heart back into a normal rhythm. This medicine is not useful for all types of irregular heart beats. It may be used to test the heart for coronary artery disease.
What are the side effects of adenosine?
Injections of adenosine can cause breathing problems and chest pain, especially when given at high doses. Adenosine can also cause headache, heart pounding, low blood pressure, nausea, sweating, flushing, lightheadedness, sleep problems, coughing, and anxiety.
What is inj dopamine?
Dopamine 200mg Injection is a medicine used for the treatment of low blood pressure due to heart attack, infection, heart surgery, or trauma. It is also useful in heart failure. It increases the blood pressure by increasing pumping capacity of the heart and improving blood flow in the body.
How does adenosine stop SVT?
Adenosine is one of components of RNA, but given intravenously, it works to terminate SVTs by binding to the AV node’s A1 receptors. This inhibits adenylyl cyclase, ultimately increasing potassium efflux from the cell, causing hyperpolarization, and thereby “blocking” the AV node.
How does amiodarone work?
It is used to restore normal heart rhythm and maintain a regular, steady heartbeat. Amiodarone is known as an anti-arrhythmic drug. It works by blocking certain electrical signals in the heart that can cause an irregular heartbeat.
What does caffeine do to adenosine?
To a nerve cell, caffeine looks like adenosine: Caffeine binds to the adenosine receptor. However, caffeine doesn’t slow down the cell’s activity like adenosine would. As a result, the cell can no longer identify adenosine because caffeine is taking up all the receptors that adenosine would normally bind to.
How does ATP affect sleep?
Furthermore, the intracellular AMP/ATP ratio controls the activity of AMP-activated protein kinase, which is a potent energy regulator and is recently reported to play a role in the regulation of sleep homeostasis. Brain ATP may support multiple functions in the regulation of the sleep/wake cycle and sleep homeostasis.
How adenosine works for sleep?
Adenosine acting in the basal forebrain is a key mediator of sleep homeostasis. Extracellular adenosine concentrations increase during wakefulness, especially during prolonged wakefulness and lead to increased sleep pressure and subsequent rebound sleep.
Is adenosine used for cardioversion?
Immediate electrical cardioversion is indicated if the arrhythmia is associated with hemodynamic collapse. Adenosine is the preferred drug in those patients in whom verapamil has failed or may cause adverse effects, such as those with heart failure or wide-complex tachycardia.
