Học thuậtThân thiện
Definition
Noun: A synthetic compound used as a beta-adrenergic blocking agent (beta-blocker). It works by blocking the action of certain natural chemicals in the body, such as epinephrine, on the heart and blood vessels. This effect slows the heart rate, lowers blood pressure, and reduces the heart's demand for oxygen.
Usage
Nadolol is prescribed by doctors to manage specific cardiovascular conditions. * It is primarily used to treat hypertension (high blood pressure). * It is also used to treat angina pectoris (chest pain due to heart disease). * It may be used to manage certain heart rhythm disorders or to prevent migraine headaches.
Examples

Advanced Usage
- Therapeutic Class: Nadolol belongs to a class of drugs known as non-selective beta-blockers, meaning it blocks both beta-1 and beta-2 adrenergic receptors.
- Medical Context: It is often described as a first-line or second-line agent in treatment guidelines for hypertension and chronic stable angina.
Variants and Related Words
