TENORIC LD 25MG

# ATENOLOL 25 MG + CHLORTHALIDONE 6.25 MG ## SHORT DESCRIPTION **Atenolol 25 mg + Chlorthalidone 6.25 mg** is a prescription combination medicine used primarily for the treatment of **high blood pressure (hypertension)**. It combines atenolol, a **beta-blocker**, with chlorthalidone, a **thiazide-like diuretic**. Atenolol helps slow the heart rate and reduce the workload of the heart, while chlorthalidone helps the kidneys remove excess sodium and water. Together, they help lower blood pressure and may reduce the risk of cardiovascular complications associated with uncontrolled hypertension. --- ## KEY BENEFITS * Helps control **high blood pressure**. * Combines two complementary blood-pressure-lowering medicines. * Atenolol reduces heart rate and cardiac workload. * Chlorthalidone promotes elimination of excess sodium and fluid. * May help reduce the long-term risk of complications associated with uncontrolled hypertension. * Convenient combination therapy for patients who require more than one antihypertensive medicine. --- ## USES / INDICATIONS ### 1. Hypertension Atenolol + chlorthalidone is primarily used to help manage **high blood pressure**. Effective blood-pressure control can help reduce the risk of: * Stroke * Heart attack * Heart failure * Kidney complications * Other cardiovascular complications ### 2. Other Cardiovascular Conditions Atenolol may be prescribed for certain other heart-related conditions. However, this combination should only be used for an indication specifically determined by a healthcare professional. --- ## HOW IT WORKS ### Atenolol 25 mg Atenolol is a **beta-1 selective adrenergic receptor blocker**. It reduces the effects of adrenaline on the heart, resulting in: * Slower heart rate * Reduced force of contraction * Reduced cardiac workload * Lower blood pressure ### Chlorthalidone 6.25 mg Chlorthalidone is a **thiazide-like diuretic**. It increases the elimination of sodium and water through the kidneys. This reduces fluid volume and contributes to lower blood pressure. ### Combined Action **Atenolol → slows the heart and reduces cardiac workload** **Chlorthalidone → increases sodium and water elimination** **Combined effect → helps lower blood pressure** --- ## DOSAGE & ADMINISTRATION > **Take this medicine only as prescribed by your healthcare professional.** The appropriate dosage depends on blood-pressure response, heart rate, kidney function, age, other medicines, and individual health conditions. For a product containing **Atenolol 25 mg + Chlorthalidone 6.25 mg**, take the prescribed dose exactly as directed. ### How to Take * It is commonly taken **once daily**, depending on the prescribed regimen. * Take it at approximately the same time each day. * It may generally be taken with or without food. * Because chlorthalidone can increase urination, taking the medicine earlier in the day may be convenient. * Swallow the tablet with water unless otherwise instructed. ### Missed Dose Take the missed dose when you remember unless it is almost time for the next dose. **Do not take two doses together.** ### Important Do **not stop atenolol suddenly** without medical advice, especially if you have heart disease. Your healthcare professional may gradually reduce the dose when discontinuing treatment. --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Dizziness * Tiredness or fatigue * Headache * Slow heartbeat * Cold hands or feet * Increased urination * Nausea * Stomach discomfort ### Chlorthalidone-Related Effects Chlorthalidone may cause changes in electrolyte levels, including: * Low potassium * Low sodium * Low magnesium * Increased uric acid * Dehydration ### Atenolol-Related Effects Atenolol may cause: * Slow heart rate * Fatigue * Dizziness * Cold extremities * Reduced exercise tolerance * Sleep disturbances * Sexual dysfunction in some individuals ### Serious Side Effects Seek prompt medical attention for: * Fainting * Very slow heartbeat * Severe dizziness * Difficulty breathing * Swelling of the legs * Severe weakness or confusion * Significant dehydration * Severe allergic reaction --- ## PRECAUTIONS & WARNINGS ### Low Heart Rate Atenolol can slow the heart rate. Inform your doctor if you have **bradycardia** or certain heart conduction disorders. ### Heart Failure Beta-blockers may be used in selected patients with heart failure, but treatment requires appropriate medical supervision. ### Asthma and Breathing Disorders Although atenolol is relatively beta-1 selective, beta-blockers can sometimes cause or worsen bronchospasm. Tell your healthcare professional if you have: * Asthma * COPD * Other breathing disorders ### Diabetes Atenolol may mask some warning symptoms of **low blood sugar**, particularly a rapid heartbeat. People with diabetes may require closer glucose monitoring. ### Kidney Disease People with kidney impairment may require closer monitoring of kidney function, blood pressure, and electrolyte levels. ### Electrolyte Imbalance Chlorthalidone can reduce potassium and sodium levels. Your healthcare professional may monitor: * Potassium * Sodium * Kidney function * Uric acid ### Gout Chlorthalidone can increase uric acid and may trigger or worsen **gout** in susceptible individuals. ### Dehydration Excessive fluid loss can cause: * Dizziness * Weakness * Low blood pressure * Electrolyte disturbances ### Surgery Inform your doctor or anesthetist that you are taking atenolol before undergoing surgery. ### Pregnancy Tell your healthcare professional if you are pregnant or planning pregnancy. Your doctor will assess whether this combination is appropriate. ### Breastfeeding Discuss treatment with your healthcare professional if you are breastfeeding. --- ## DRUG INTERACTIONS Tell your doctor or pharmacist about all prescription medicines, OTC medicines, vitamins, and herbal supplements you use. ### Other Blood Pressure Medicines Combining this medicine with other antihypertensive medicines can cause excessive lowering of blood pressure. ### Verapamil or Diltiazem Calcium channel blockers such as **verapamil and diltiazem** may further slow the heart rate or impair cardiac conduction when combined with atenolol. ### Digoxin Digoxin and atenolol can both slow the heart rate and may increase the risk of bradycardia. ### Diabetes Medicines Atenolol can mask some symptoms of hypoglycemia and may require closer blood-glucose monitoring. ### NSAIDs Medicines such as **ibuprofen, naproxen, or diclofenac** may reduce the blood-pressure-lowering effect and can affect kidney function in susceptible individuals. ### Lithium Chlorthalidone can increase lithium levels and potentially increase the risk of lithium toxicity. ### Other Diuretics Using additional diuretics may increase the risk of dehydration and electrolyte abnormalities. ### Corticosteroids Some corticosteroids may increase the risk of low potassium when used with diuretics. --- ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep in the original packaging. * Protect from excessive heat and moisture. * Keep away from direct sunlight. * Keep out of reach and sight of children. * Keep the container tightly closed where applicable. * Do not use after the expiry date. * Do not use tablets from damaged or tampered packaging. --- ## PRESCRIPTION STATUS **Prescription Medicine** Atenolol 25 mg + Chlorthalidone 6.25 mg should be used under the supervision of a qualified healthcare professional.
