🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Atenolol selectively blocks beta-1 adrenergic receptors located primarily in the heart. By blocking these receptors, it reduces the effects of catecholamines (adrenaline and noradrenaline), leading to a decrease in heart rate, contractility, and cardiac output. This results in lower blood pressure and reduced myocardial oxygen demand. At higher doses, it may also block beta-2 receptors in the lungs and blood vessels, but it is relatively cardioselective at usual doses.
Mechanism Steps
💡 How to Take Teenol 100mg Tablet
Strength: Atenolol 100 mg immediate-release tablet
Dosage Information
| Adult Dosage | The usual adult dose of this medicine for hypertension or angina is 50 mg to 100 mg once daily. For post-myocardial infarction, the typical dose is 50 mg twice daily or 100 mg once daily. The dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and response to therapy. Do not adjust the dose without medical advice. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may be more sensitive to the effects of this medicine, especially bradycardia and hypotension. Start with a lower dose and titrate slowly. Renal function should be assessed before initiating therapy. |
| Renal Impairment | In patients with renal impairment, the dose of this medicine should be reduced. For creatinine clearance 15-35 mL/min, the dose should not exceed 50 mg daily. For creatinine clearance less than 15 mL/min, the dose should not exceed 25 mg daily. Doses should be administered after dialysis on dialysis days. |
| Hepatic Impairment | No specific dosage adjustment is required for hepatic impairment, as atenolol is not significantly metabolized by the liver. However, caution is advised and patients should be monitored. |
| Maximum Daily Dose | The maximum recommended daily dose is 100 mg for hypertension and angina, and 100 mg for post-myocardial infarction. Doses above 100 mg daily do not provide additional benefit and may increase side effects. |
