Adenosine is a naturally occurring substance that relaxes and dilates blood vessels. Adenosine also affects the electrical activity of the heart. Adenosine is used to help restore normal heartbeats in people with certain heart rhythm disorders.
Overview. Adenosine is a chemical found in human cells. There are three different forms: adenosine, adenosine monophosphate (AMP), and adenosine triphosphate (ATP). Adenosine blocks...
Adenosine’s use as a pharmacological drug works through receptors called purinergic adenosine receptors found throughout the body. As a diagnostic agent, adenosine can be utilized in myocardial perfusion stress imaging due to its vasodilatory effects.
Adenosine is one of the four nucleoside building blocks of RNA (and its derivative deoxyadenosine is a building block of DNA), which are essential for all life on Earth. Its derivatives include the energy carriers adenosine mono-, di-, and triphosphate, also known as AMP/ADP/ATP.
Although adenosine is a fundamental part of ATP, when it comes to providing energy to a cell and fueling cellular processes, the phosphate molecules are what really matter. The most energy-loaded composition for adenosine is ATP, which has three phosphates.
Adenosine is a medication that can bring your heart back to a normal rhythm. It’s an injection that a healthcare provider will give you in a hospital or clinic setting. Brand names of adenosine are Adenocard® and Adenoscan®.
Physiological and pharmacological role of Adenosine. In the body, adenosine helps in cellular energy transfer by forming molecules like adenosine triphosphate (ATP) and adenosine diphosphate...
Adenosine has a key role in the adaptive response in pulmonary hypertension and heart failure, with the most relevant effects being slowing of heart rhythm, coronary vasodilation and decreasing blood pressure.
Adenosine is a medication belonging to class V antidysrhythmics, used to treat a type of irregular heart rhythm disorder known as paroxysmal supraventricular tachycardia (PSVT). PSVT is a condition in which intermittent episodes of rapid heart rate occur starting from the region above the ventricles.
Adenosine has been used in the emergency treatment of arrhythmia for more than nine decades. However, cardiologists are often unfamiliar about its basic mechanism and various diagnostic and therapeutic uses, considering it mainly as a therapeutic drug for supraventricular tachycardia.
