What is the classification of atenolol?

Atenolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

What is the pharmacologic action of atenolol?

Cardioselective beta-1-adrenergic antagonists such as atenolol work by selectively binding to the beta-1 adrenergic receptors found in vascular smooth muscle and the heart, blocking the positive inotropic and chronotropic actions of endogenous catecholamines such as isoproterenol, norepinephrine, and epinephrine, …

What is the classification of beta blockers?

Beta-blockers that are used clinically can be divided into two classes: 1) non-selective blockers (block both β1and β2 receptors), or 2) relatively selective β1 blockers (“cardioselective” beta-blockers).

What is the classification of atenolol quizlet?

Atenolol (Tenormin) is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins).

What is the mechanism of action of beta blockers?

Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force, which lowers blood pressure. Beta blockers also help widen veins and arteries to improve blood flow.

Is atenolol a vasodilator?

Since beta blockers are heterogenous class of agents with diverse pharmacologic properties, the unfavorable data revealed in the recent meta-analysis is from studies involving the traditional beta blockers (propranalol, atenolol) which are non vasodilating.

What is the classification of albuterol quizlet?

Proventil, Ventolin. What is the drug CLASS of Albuterol? Sympathomimetic, bronchodilator.

What is the priority assessment needed prior to administration of atenolol?

Before administering a Beta-1 antagonist such as atenolol, the nurse should assess the patient’s apical pulse and blood pressure to confirm they are within normal range. Atenolol causes a negative inotropic effect by weakening the contraction of the heart and thus, decreases the patient’s blood pressure.

Is atenolol an ACE inhibitor or ARB?

Atenolol is also used to treat chest pain (angina), for management of acute heart attack (myocardial infarction), and occasionally for thyroid storm management. Cozaar and atenolol belong to different drug classes. Cozaar is an angiotensin receptor blocker (ARB) and atenolol is a beta-blocker.

What is the mechanism of action of calcium channel blockers?

They work by preventing calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to squeeze (contract) more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open.

What does atenolol do to your heart?

If you have high blood pressure, taking atenolol helps prevent future heart disease, heart attacks and strokes. It can also be used to prevent chest pain caused by angina. Atenolol works by slowing down your heart rate, making it easier for your heart to pump blood around your body.

What is the mechanism of action of a sodium channel blocker?

A class of drugs that act by inhibition of sodium influx through cell membranes. Blockade of sodium channels slows the rate and amplitude of initial rapid depolarization, reduces cell excitability, and reduces conduction velocity. An anti-anginal drug used for the treatment of chronic angina.

What are the two types of calcium channel blockers?

There are two distinct chemical classes of CCBs: the dihydropyridines (such as nifedipine and amlodipine) and the nondihydropyridines (diltiazem and verapamil).
