उपयोग: यह दवा एटेनोलोल नामक सक्रिय तत्व से बनी है और यह बीटा-ब्लॉकर वर्ग की दवा है। इसका उपयोग मुख्य रूप से उच्च रक्तचाप (हाइपरटेंशन), एनजाइना (सीने में दर्द), और दिल के दौरे के बाद जीवित रहने की दर बढ़ाने के लिए किया जाता है। यह दिल की धड़कन को धीमा करती है और दिल पर दबाव कम करती है, जिससे रक्तचाप कम होता है। यह दवा आमतौर पर दिन में एक बार मुँह से ली जाती है। इसे डॉक्टर की सलाह के बिना अचानक बंद नहीं करना चाहिए, क्योंकि इससे एनजाइना या दिल का दौरा पड़ सकता है।
साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में थकान, चक्कर आना, हाथ-पैर ठंडे होना, और धड़कन धीमी होना शामिल हैं। कुछ लोगों को नींद में गड़बड़ी, मतली, दस्त या कब्ज हो सकती है। गंभीर दुष्प्रभावों में बहुत धीमी धड़कन, हृदय गति रुकना, सांस लेने में कठिनाई (विशेषकर अस्थमा रोगियों में), और दिल की विफलता बढ़ना शामिल है। यदि आपको कोई भी गंभीर या लगातार दुष्प्रभाव महसूस हो, तो तुरंत डॉक्टर से संपर्क करें।
सुरक्षा सलाह: इस दवा को शुरू करने से पहले अपने डॉक्टर को अपनी सभी चिकित्सीय स्थितियों के बारे में बताएं, विशेष रूप से अस्थमा, सीओपीडी, मधुमेह, गुर्दे की बीमारी, या हृदय की विफलता। इस दवा को अचानक बंद न करें, क्योंकि इससे सीने में दर्द या दिल का दौरा पड़ सकता है। डॉक्टर धीरे-धीरे खुराक कम करेंगे। इस दवा के साथ शराब न पिएं। चक्कर आ सकते हैं, इसलिए वाहन चलाने या मशीनरी चलाने से बचें जब तक आपको पता न चल जाए कि यह दवा आपको कैसे प्रभावित करती है। यदि आप गर्भवती हैं, गर्भवती होने की योजना बना रही हैं, या स्तनपान करा रही हैं, तो अपने डॉक्टर को बताएं।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a cardioselective beta-1 adrenergic receptor blocker. It works by competitively blocking beta-1 receptors primarily located in the heart, which reduces the effects of catecholamines such as adrenaline and noradrenaline. This leads to a decrease in heart rate, myocardial contractility, and cardiac output. It also reduces renin release from the kidneys, which lowers angiotensin II and aldosterone levels, contributing to blood pressure reduction. 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 beta 100mg tablet
Strength: Atenolol 100 mg immediate-release tablet
Dosage Information
| Adult Dosage | The usual starting dose for hypertension is 25 to 50 mg once daily. The dose may be increased to 100 mg once daily based on response. For angina, the typical dose is 50 to 100 mg once daily. After myocardial infarction, the recommended dose is 50 mg twice daily or 100 mg once daily. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| 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, dose adjustment is required based on creatinine clearance. For creatinine clearance 15-35 mL/min, the maximum dose is 50 mg daily. For creatinine clearance less than 15 mL/min, the maximum dose is 25 mg daily. Doses may be administered every other day. Consult a nephrologist for individualized dosing. |
| Hepatic Impairment | No specific dosage adjustment is required for hepatic impairment, as atenolol is primarily excreted unchanged by the kidneys. However, monitor closely for any signs of toxicity. |
| Maximum Daily Dose | The maximum recommended daily dose is 100 mg for hypertension and angina. For post-myocardial infarction, up to 100 mg daily may be used. Doses above 100 mg daily do not provide additional benefit and may increase side effects. |

🤱 Lactation Safety
Atenolol is excreted in human breast milk in small amounts. There is a potential for adverse effects in the nursing infant, such as bradycardia and hypotension. Caution is advised; consider alternative medicines or monitor the infant closely if this medicine is used during breastfeeding.
💊 Overdose Management
Overdose of this medicine can cause severe bradycardia, hypotension, heart failure, bronchospasm, and hypoglycemia. If overdose is suspected, seek emergency medical attention immediately. Treatment is supportive and may include atropine for bradycardia, intravenous fluids for hypotension, and beta-agonists for bronchospasm. Hemodialysis can remove atenolol from the bloodstream.
⏰ Missed Dose
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double the dose to catch up.
Additional Safety Advice
Before starting this medicine, inform your doctor about all your medical conditions, especially asthma, chronic obstructive pulmonary disease (COPD), diabetes, kidney disease, liver disease, heart failure, or thyroid disorders. Do not stop taking this medicine suddenly, as it can cause chest pain, irregular heartbeats, or even a heart attack. Your doctor will likely reduce your dose gradually over one to two weeks. Avoid drinking alcohol while taking this medicine, as it can increase drowsiness and lower blood pressure further. This medicine may cause dizziness, so avoid driving or operating heavy machinery until you know how it affects you. If you have diabetes, this medicine can mask the symptoms of low blood sugar (such as rapid heartbeat), so monitor your blood glucose levels regularly. Inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding. This medicine may affect the fetus or pass into breast milk. Keep all appointments with your doctor and laboratory for monitoring your blood pressure, heart rate, and kidney function. Do not share this medicine with others, even if they have similar symptoms.
👴 Special Considerations for Elderly
💡 For Patients Above 65
Elderly patients are more prone to side effects such as dizziness, bradycardia, and hypotension. Start with a lower dose and titrate slowly. Monitor renal function regularly, as kidney function declines with age. Falls risk may increase due to dizziness; take precautions.
🤰 Pregnancy Planning (TTC)
If you are planning to become pregnant, consult your doctor before conception. This medicine may not be the best choice during pregnancy due to potential risks to the fetus. Your doctor may switch you to a safer alternative. Use effective contraception while taking this medicine unless otherwise advised.
🏥 Post-Surgery Considerations
Inform your surgeon and anesthesiologist that you are taking this medicine. It may interact with anesthetic agents and affect heart rate and blood pressure during surgery. Your doctor may adjust the dose or temporarily stop it before surgery. Do not stop on your own.
🦷 Dental Procedures
Inform your dentist that you are taking this medicine, especially if you are undergoing procedures that may cause bleeding or require anesthesia. This medicine may interact with certain local anesthetics containing epinephrine, potentially causing severe hypertension. Your dentist may need to adjust the anesthetic.
💚 Lifestyle Tips for Better Results
🏋️ Exercise Considerations
This medicine can reduce your heart rate and blood pressure during exercise, potentially causing dizziness or fatigue. Avoid strenuous activities until you know how the medicine affects you. Stay hydrated and warm up gradually. If you experience chest pain, severe shortness of breath, or dizziness during exercise, stop and seek medical attention.
🥗 Diet Recommendations
💼 Impact on Daily Work & Life
This medicine may cause dizziness or fatigue, especially when you first start taking it. Avoid driving or operating heavy machinery until you know how it affects you. It should not significantly impact your ability to work, but inform your employer if your job involves safety-sensitive tasks. Regular breaks and hydration can help manage fatigue.
🛑 When to Stop This Medicine
Do not stop this medicine without consulting your doctor. Your doctor may decide to stop it if you experience serious side effects, your blood pressure is well-controlled and they want to try a different approach, or if you develop a contraindication. Always taper gradually under medical supervision.
📅 Long-Term Use Effects
Long-term use of this medicine is generally safe when monitored appropriately. It may reduce cardiovascular events and improve survival in patients with heart disease. However, regular monitoring of blood pressure, heart rate, and kidney function is necessary. Long-term use may also lead to reduced exercise tolerance and cold extremities. Do not stop the medicine without medical advice.
