{{/items}} {{^items}}Description
A cardioselective beta-adrenergic blocker possessing properties and potency similar to propranolol, but without a negative inotropic effect.
Indication
For the management of hypertention and long-term management of patients with angina pectoris
Mechanism of Action
Like metoprolol, atenolol competes with sympathomimetic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart and vascular smooth muscle, inhibiting sympathetic stimulation. This results in a reduction in resting heart rate, cardiac output, systolic and diastolic blood pressure, and reflex orthostatic hypotension. Higher doses of atenolol also competitively block beta(2)-adrenergic responses in the bronchial and vascular smooth muscles.
Pharmacokinetics
- Absorption
- Approximately 50% of an oral dose is absorbed from the gastrointestinal tract, the remainder being excreted unchanged in the feces.
- Distribution
- Metabolism
- Hepatic (minimal)
- Elimination
Toxicity
LD50=2000-3000 mg/kg(orally in mice). Symptoms of an atenolol overdose include a slow heart beat, shortness of breath, fainting, dizziness, weakness, confusion, nausea, and vomiting.
