LOSTAT 50MG

# Losartan Potassium 50 mg ## Short Description **Losartan Potassium 50 mg** is an **angiotensin II receptor blocker (ARB)** used primarily to treat **high blood pressure (hypertension)**. It may also be prescribed for certain patients with **heart failure, diabetic kidney disease, or cardiovascular risk factors**, depending on the clinical situation. Losartan works by blocking the action of angiotensin II, a hormone that causes blood vessels to narrow. This helps blood vessels relax and can lower blood pressure. --- ## Key Benefits * Helps lower **high blood pressure** * Relaxes and widens blood vessels * May help reduce the risk of cardiovascular complications associated with uncontrolled hypertension * Can help protect kidney function in certain patients with **type 2 diabetes and hypertension** * May be used in selected patients with **heart failure** * Usually taken **once daily** * Does not generally cause the persistent dry cough commonly associated with ACE inhibitors --- ## Uses / Indications ### 1. Hypertension Losartan 50 mg is commonly used to treat **high blood pressure** in adults. It may be used alone or together with other antihypertensive medicines. ### 2. Diabetic Kidney Disease Losartan may be prescribed for certain patients with **type 2 diabetes, hypertension, and diabetic nephropathy** to help reduce kidney-related complications. ### 3. Stroke Risk Reduction In selected patients with hypertension and **left ventricular hypertrophy**, losartan may be used to help reduce the risk of stroke. ### 4. Heart Failure Losartan may be used in certain patients with heart failure when clinically appropriate, although the preferred ARB or other heart-failure regimen depends on the individual patient's condition. --- ## How It Works Losartan belongs to the **angiotensin II receptor blocker (ARB)** class. Angiotensin II normally binds to AT1 receptors and causes: * Blood vessel constriction * Increased blood pressure * Sodium and water retention * Increased workload on the heart Losartan blocks the **AT1 receptor**, reducing the effects of angiotensin II. **Losartan → blocks AT1 receptors → blood vessels relax → reduced vascular resistance → lower blood pressure.** --- ## Dosage & Administration > **Take losartan exactly as prescribed by your healthcare professional.** ### Adults With Hypertension A commonly recommended starting dose is **50 mg once daily**. Some patients may be started at a lower dose, particularly when they are taking diuretics, have certain liver problems, or may be susceptible to low blood pressure. The dose may be adjusted according to blood pressure response. ### Maximum Dose For some indications, doses may be increased up to **100 mg per day** under medical supervision. ### Children Losartan may be used in certain children with hypertension, but the dose is generally determined according to **body weight and clinical circumstances**. ### How to Take * Take once daily at approximately the same time each day. * May be taken **with or without food**. * Swallow with water. * Continue taking it even if you feel well, unless your doctor tells you to stop. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. **Do not take two doses at the same time.** --- ## Side Effects ### Common Side Effects Possible side effects include: * Dizziness * Headache * Fatigue * Low blood pressure * Back pain * Upper respiratory symptoms * Increased potassium levels Some people may experience dizziness when treatment is first started or when the dose is increased. ### Serious Side Effects Seek medical attention if you develop: * Severe dizziness or fainting * Significant reduction in urine output * Severe weakness * Irregular heartbeat * Facial, lip, tongue, or throat swelling * Difficulty breathing * Signs of severe kidney problems ### Hyperkalemia Losartan can increase blood potassium levels (**hyperkalemia**), particularly in people with kidney disease or those taking other medicines that increase potassium. --- ## Precautions & Warnings ### Pregnancy **Losartan should not be used during pregnancy.** Medicines that act on the renin-angiotensin system can cause serious injury or death to the developing fetus, particularly during later pregnancy. If pregnancy occurs while taking losartan, contact your healthcare professional promptly. ### Kidney Disease Losartan can affect kidney function, particularly in people with: * Kidney disease * Dehydration * Renal artery stenosis * Heart failure Kidney function may need to be monitored. ### High Potassium Losartan can increase potassium levels. Avoid taking potassium supplements or potassium-containing salt substitutes unless specifically recommended by your healthcare professional. ### Low Blood Pressure Dizziness or fainting may occur, especially in patients who are: * Dehydrated * Taking diuretics * On multiple blood-pressure medicines * Experiencing vomiting or diarrhea ### Liver Disease Patients with liver impairment may require a lower starting dose. ### Aortic or Mitral Valve Disease Patients with significant heart-valve conditions should inform their healthcare professional before starting treatment. ### Surgery Tell your doctor or anesthetist that you are taking losartan before surgery. --- ## Drug Interactions ### Potassium Supplements Potassium supplements and potassium-containing salt substitutes may increase the risk of **hyperkalemia**. ### Potassium-Sparing Diuretics Medicines such as: * Spironolactone * Eplerenone * Amiloride * Triamterene may further increase potassium levels. ### ACE Inhibitors Combining losartan with ACE inhibitors generally increases the risk of: * Kidney problems * Low blood pressure * Hyperkalemia This combination is generally avoided unless specifically indicated and closely supervised. ### NSAIDs Medicines such as: * Ibuprofen * Naproxen * Diclofenac may reduce the blood-pressure-lowering effect of losartan and increase the risk of kidney problems, particularly in dehydrated or vulnerable patients. ### Lithium Losartan may increase lithium concentrations and the risk of lithium toxicity. ### Diuretics Diuretics may increase the blood-pressure-lowering effect of losartan and may increase the risk of dizziness or low blood pressure. Always tell your doctor or pharmacist about all prescription medicines, OTC medicines, vitamins, and supplements you use. --- ## Storage Information * Store at room temperature according to the manufacturer's instructions. * Keep tablets in their original packaging. * Protect from excessive heat and moisture. * Keep away from direct sunlight. * Keep out of reach and sight of children. * Do not use after the expiry date. * Keep the container tightly closed. --- ## Prescription Status **Losartan Potassium 50 mg is generally a prescription medicine.** It should be used under the supervision of a qualified healthcare professional, particularly because blood pressure, kidney function, and potassium levels may require monitoring.
