LOSARTAS 50 by INTAS PHARMACEUTICALS LTD

Name

• Brand Name: LOSARTAS 50
• Common Name: Losartan

Composition

LOSARTAS 50 contains Losartan 50 mg as its active ingredient (Losartan Potassium 50 mg).

Uses

LOSARTAS 50 is primarily prescribed for the management and treatment of several cardiovascular and renal conditions:

• High Blood Pressure (Hypertension): It helps relax blood vessels, lowering blood pressure and easing the strain on the heart and blood vessels.
• Heart Failure: It improves heart function and reduces symptoms such as tiredness and shortness of breath.
• Prevention of Heart Attack and Stroke: By lowering blood pressure and improving blood flow, it helps reduce the risk of these life-threatening cardiovascular events.
• Diabetic Nephropathy: It is used to protect kidney function in patients with type 2 diabetes and high blood pressure, helping to slow kidney damage and disease progression.
• Stroke Reduction in Left Ventricular Hypertrophy: It decreases the risk of stroke in patients with hypertension and left ventricular hypertrophy (enlargement of the heart's left chamber).

Dosage and Administration

LOSARTAS 50 is an oral tablet meant to be swallowed whole with water.

• Typical Starting Dose: For adults, the usual starting dose is 50 mg once daily for hypertension, diabetic nephropathy, and stroke risk reduction in left ventricular hypertrophy.
• Administration: It can be taken with or without food, preferably at the same time each day to maintain consistent levels in the body.
• Adjustments: The dosage may be adjusted by a doctor based on the patient's blood pressure response, potentially increasing to 100 mg once daily.
• Special Considerations: Patients with possible intravascular depletion (e.g., those on diuretic therapy) may start with a lower dose of 25 mg once daily. The first dose might be recommended before bedtime as it can cause dizziness.

Side Effects

Common side effects include:

• Dizziness
• Headache
• Fatigue/Weakness
• Nausea
• Stomach pain/Upset stomach
• Diarrhea or Constipation
• Cough, Stuffy nose, Upper respiratory tract infections
• Back pain, Joint pain
• Low blood pressure (hypotension)

Serious side effects, though rare, can include:

• Kidney damage
• Severely high potassium levels
• Angioedema (swelling of the face, lips, throat, or tongue)
• Severe allergic reactions (anaphylaxis)

Precautions

• Pregnancy: LOSARTAS 50 is highly unsafe and contraindicated during the second and third trimesters of pregnancy as it can cause serious harm or even endanger the life of the unborn baby.

• Liver Impairment: Use with caution in patients with liver disease, and it is contraindicated in severe hepatic impairment.
• Kidney Disease: Patients with severe heart failure, chronic kidney disease, or renal artery stenosis should use it cautiously, as it may impair kidney function. Regular monitoring of kidney function is advised.
• Hyperkalemia: It should be used with caution or avoided in patients with high potassium levels, and potassium supplements or salt substitutes containing potassium should not be used without consulting a doctor.
• Drug Interactions: Inform your doctor about all current medications, as it may interact with diuretics, NSAIDs (e.g., ibuprofen), lithium, and other antihypertensive agents, increasing the risk of adverse effects or reducing efficacy.
• Alcohol: Consuming alcohol with LOSARTAS 50 is unsafe and may increase the risk of side effects like dizziness and excessive lowering of blood pressure.
• Dizziness/Drowsiness: The medicine may cause dizziness or drowsiness; therefore, caution is advised when driving or operating machinery.

LOSARTAS 50 is a medication manufactured by Intas Pharmaceuticals Ltd. that contains Losartan (50mg) as its active ingredient. It is an angiotensin II receptor blocker (ARB) primarily used to treat high blood pressure.

Here are some frequently asked questions about LOSARTAS 50:

What is LOSARTAS 50 used for?

LOSARTAS 50 is primarily used to treat high blood pressure (hypertension). It is also prescribed to lower the risk of stroke in patients with high blood pressure and an enlarged heart (left ventricular hypertrophy), and to protect the kidneys in individuals with type 2 diabetes and high blood pressure. It may also be used in cases of heart failure.

How does LOSARTAS 50 work?

LOSARTAS 50 contains Losartan, which is an angiotensin II receptor blocker (ARB). It works by blocking the action of angiotensin II, a natural substance in the body that causes blood vessels to narrow. By blocking this substance, LOSARTAS 50 helps to relax and widen the blood vessels, making it easier for blood to flow and reducing blood pressure. This lessens the strain on the heart and improves blood flow throughout the body.

What is the usual dosage of LOSARTAS 50?

For adults with high blood pressure, the typical starting dosage is 50 mg once daily. Your doctor may adjust the dose based on your blood pressure response, with a maximum of 100 mg once daily. For patients taking diuretics, a starting dose of 25 mg once daily might be prescribed. When used to lower the risk of stroke in patients with high blood pressure and left ventricular hypertrophy, or for diabetic nephropathy, the recommended starting dosage is also 50 mg once daily, which can be increased to 100 mg once daily if needed. LOSARTAS 50 is usually taken once a day, with or without food.

What are the possible side effects of LOSARTAS 50?

Common side effects of Losartan include dizziness, headache, stuffy nose, fatigue, back pain, joint pain, nausea, vomiting, and diarrhea. More serious, but rare, side effects can include kidney damage, severely low blood pressure, very high potassium levels, and angioedema (swelling of the face, neck, and mouth). You should report any severe side effects like skin rash, itching, hives, swelling of the face, lips, tongue, or throat, difficulty breathing or swallowing, chest pain, or symptoms of high potassium levels (muscle weakness, fast or irregular heartbeat) to your doctor immediately.

Is LOSARTAS 50 safe during pregnancy or breastfeeding?

No, LOSARTAS 50 is not safe during pregnancy. It carries a boxed warning from the FDA, indicating it can cause serious harm or even death to the unborn baby, especially if taken during the second and third trimesters. If you become pregnant while taking LOSARTAS 50, you should stop taking it and contact your doctor immediately.

Regarding breastfeeding, the product label recommends that women who are breastfeeding should not use losartan. Animal studies suggest that losartan can pass into breast milk and could potentially affect the nursing baby's kidneys. Your healthcare provider can discuss the potential benefits versus risks and suggest the best treatment option for you.

Can LOSARTAS 50 be taken with other medications?

LOSARTAS 50 can interact with several other medications. It's crucial to inform your doctor about all prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking.

Significant interactions can occur with:

• Diuretics (water pills): Can increase the risk of severely low blood pressure or high potassium levels.
• NSAIDs (Nonsteroidal Anti-inflammatory Drugs) like ibuprofen, naproxen, and celecoxib: Can reduce the blood pressure-lowering effect of losartan and increase the risk of kidney problems, especially in older adults or those who are dehydrated.
• Potassium supplements or salt substitutes containing potassium: Can lead to dangerously high potassium levels in the blood.
• ACE inhibitors and Aliskiren: Taking losartan with these can significantly increase the risk of low blood pressure, high potassium levels, and kidney damage. If you have diabetes, you should not take losartan if you are also taking aliskiren.
• Lithium: Losartan may increase the level of lithium in the body, leading to toxicity.
• Alcohol: Can worsen the blood pressure-lowering effect of losartan and increase the possibility of dizziness or fainting.
• Grapefruit and grapefruit juice: Can make losartan less effective.

What precautions should be taken while taking LOSARTAS 50?

Before taking LOSARTAS 50, tell your doctor if you have allergies to losartan or any other medications, or if you have a history of heart failure, kidney disease, or liver disease. It's important to monitor your blood pressure regularly as directed by your doctor. Be aware that LOSARTAS 50 can cause dizziness, lightheadedness, or fainting, especially when you first start taking it or when getting up too quickly. Avoid alcohol and do not use potassium supplements or salt substitutes containing potassium without consulting your doctor. If you experience severe or continuing nausea, vomiting, or diarrhea, contact your doctor as these conditions can lead to dehydration and low blood pressure.

What happens if a dose of LOSARTAS 50 is missed?

If you miss a dose of LOSARTAS 50, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a forgotten one.

How should LOSARTAS 50 be stored?

LOSARTAS 50 tablets should be stored in a closed container at room temperature, away from heat, moisture, and direct light. Do not freeze the medication. Keep it out of the reach of children.
