Losartan - Overview and Uses Losartan is a medication that belongs to a class of drugs known as angiotensin receptor blockers (ARBs). It is primarily used to treat high blood pressure (hypertension) and kidney problems caused by diabetes.
How Losartan Works Losartan works by blocking the action of a natural substance called angiotensin II. Angiotensin II causes blood vessels to constrict, which can lead to high blood pressure. By blocking the action of angiotensin II, losartan helps to relax the blood vessels, lower blood pressure, and reduce the workload on the heart.
Losartan may be used alone or in combination with other medications to treat high blood pressure. It is also used to slow progression of kidney disease in people with type 2 diabetes and high blood pressure.
Uses of Losartan
-
High Blood Pressure: Losartan is primarily used to treat high blood pressure (hypertension). It helps lower blood pressure by relaxing the blood vessels, allowing blood to flow more smoothly. Controlling high blood pressure reduces the risk of serious complications like heart disease, stroke, and kidney disease.
-
Kidney Disease with Diabetes: Losartan is also used to slow the progression of kidney disease in people with type 2 diabetes and high blood pressure. It reduces the amount of protein released in the urine and slows kidney damage.
-
Heart Failure: In some cases, losartan may be used to treat heart failure, a condition in which the heart is unable to pump enough blood to meet the body's needs. Losartan helps reduce blood pressure, reduce the workload on the heart, and improve symptoms of heart failure.
Side Effects of Losartan While losartan is generally considered safe, it can cause some side effects. Common side effects of losartan include:
- Dizziness or lightheadedness
- Headache
- Cough
- Muscle pain or cramps
- Stomach pain or upset
Serious side effects of losartan are rare but can occur. If you experience any of the following, seek medical attention right away:
- Swelling of the face, lips, tongue, or throat
- Difficulty breathing
- Skin rash or itching
- Fever
- Chills
- Unusual bleeding or bruising
- Yellowing of the skin and eyes
Interactions of Losartan Losartan can interact with other medications, including:
- Diuretics (water pills)
- Potassium supplements
- Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs)

Introduction High blood pressure, also known as hypertension, is when the force of blood flowing through your blood vessels is consistently too high. It is a common condition that can lead to serious health problems if left untreated. High blood pressure is often referred to as a "silent killer" because most people with high blood pressure don't exhibit any symptoms, even though damage is occurring within their bodies.
-
Definition of High Blood Pressure Blood pressure is measured in millimeters of mercury (mmHg) and is written as two numbers:
- Systolic pressure (the top number) - measures the pressure in arteries when the heart beats.
- Diastolic pressure (the bottom number) - measures the pressure in arteries between beats.
For most adults, a normal blood pressure reading is:
- Most adults: Less than 120/80 mmHg
- Elevated: 120-129/80 mmHg
- Stage 1 hypertension: 130-139/80-89 mmHg
- Stage 2 hypertension: 140 or higher/90 mmHg or higher
- Causes of High Blood Pressure There are two main categories of hypertension: primary (essential) hypertension and secondary hypertension.
Primary (essential) hypertension:
- Accounts for about 90-95% of adult hypertension cases
- Exact cause is unknown
- Multiple factors contribute, including:
- Genes
- Physical changes
- Environmental or lifestyle factors
Secondary hypertension:
- Caused by an underlying condition or medication
- Typically more severe and variable than primary hypertension
- Causes can include:
- Kidney disease
- Adrenal gland disease
- Thyroid disease
- Side effect of medications (e.g., birth control pills, cold medicines, painkillers and ED pills)
- Sleep apnea
Other potential causes and risk factors:
- Age: Risk increases with age
- Family history: Having a family history of hypertension increases your risk
- Weight: Being overweight or obese is a major risk factor
- Sedentary lifestyle: Not being physically active
- Using tobacco products: Smoking damages blood vessels and makes them work harder, raising blood pressure
- Too much sodium in your diet: Excessive sodium consumption can lead to high blood pressure in some people
- Too little potassium in your diet: Potassium helps lower sodium levels in your body and ease pressure on blood vessels
- Drinking too much alcohol: Consuming more than 1-2 drinks per day can raise your blood pressure
- Stress: Ongoing stress can lead to high blood pressure
- Sleep deprivation: Continual sleep deprivation can lead to high blood pressure
- Certain medications: Certain medications, such as birth control pills, cold medicines, painkillers and ED pills, can raise blood pressure
- Symptoms of High Blood Pressure Most people with high blood pressure have no signs or symptoms, even if blood pressure readings reach dangerously high levels. However, rare symptoms may include:
- Shortness of breath
- Nosebleeds
- Dizziness
- Blurred vision
- Chest pain
- Headache
- Palpitations
- Numbness or weakness
- Severe difficulty speaking or understanding speech
- Severe confusion or drowsiness
- Sudden severe headache, vomiting, stiff neck, and/or seizures (referred to as hypertensive crisis)
- Risks of Untreated High Blood Pressure If left untreated, high blood pressure can cause serious and even life-threatening complications. These can include:
- Heart attack: High blood pressure damages arteries that lead to the heart, reducing blood flow and causing a heart attack.
- Stroke: Weakened blood vessels in the brain can rupture or leak, leading to a stroke, brain damage and death.
- Heart failure: The heart has to work harder to pump blood through rigid, narrowed or blocked arteries, leading to heart failure.
- Kidney disease and kidney failure: High blood pressure damages kidneys, reducing their ability to filter waste and excess fluids, potentially leading to kidney failure.
- Vision loss: High blood pressure can damage blood vessels in the eyes, leading to blurred vision, double vision and even blindness.
- Prevention and Treatment of High Blood Pressure If you've been diagnosed with high blood pressure, your doctor may recommend one or more of the following lifestyle changes:
- Eat a healthier diet: Adopt the Dietary Approaches to Stop Hypertension (DASH) eating plan, which focuses on whole grains, fruits, vegetables and lean protein.
- Reduce sodium: Limit sodium to 2,300 milligrams a day or less. Aim for no more than 1,500 milligrams a day if you're 51 or older, are African American, or have high blood pressure.
- Exercise regularly: Engage in 150 minutes of moderate-intensity aerobic physical activity or 75 minutes of vigorous-intensity aerobic physical activity or an equivalent combination of each spread throughout the week. Aim for 30 minutes of aerobic physical activity five days of the week.
- Get plenty of potassium: Consume 4,700 milligrams of potassium a day.
- Reduce stress: Engage in stress-reducing activities like meditation, deep breathing, or yoga. Take breaks throughout the day to stretch and relax.
- Monitor and control stress: Keep a food and activity journal to identify stressors and plan to manage them.
- Limit alcohol: Limit alcohol to one drink a day for women and two drinks a day for men.
- Quit smoking: If you're a smoker, quitting will lower your risk of high blood pressure and heart disease.
- Get enough sleep: Get 7-8 hours of sleep a night.
- Maintain a healthy weight: If you're overweight or obese, losing weight can lower your blood pressure. Ask your doctor what a healthy weight is for you.
- Get regular exercise and physical activity: Regular physical activity can help lower your blood pressure and manage stress. Aim for at least 150 minutes of moderate-intensity exercise per week.
- Try relaxation techniques: Yoga, meditation and deep breathing can help lower your blood pressure by reducing stress and promoting relaxation.
- Monitor your blood pressure regularly: Monitoring your blood pressure regularly can help you notice changes early on and alert your doctor if your blood pressure is not adequately controlled. Buy a good quality, well-fitting home device and use it as directed.
Medications for high blood pressure can include:
- Diuretics: Help remove excess fluid and sodium from your body.
- Angiotensin-converting enzyme (ACE) inhibitors: Block the action of a chemical that constricts blood vessels.
- Angiotensin II receptor blockers (ARBs): Block the action of a chemical that constricts blood vessels.
- Calcium channel blockers: Relax blood vessels and make it easier for the heart to pump blood.
- Alpha blockers: Reduce nerve impulses to blood vessels, allowing them to relax and reducing blood pressure.
- Alpha-beta blockers: Reduce nerve impulses to blood vessels, allowing them to relax and reducing blood pressure.
- Central-acting agents: Act on the brain to lower blood pressure.
- Vasodilators: Relax the muscles in blood vessel walls, lowering blood pressure
- Frequently Asked Questions Q: What is the most common cause of high blood pressure? A: The most common cause of high blood pressure is age. However, a combination of genetic, lifestyle and environmental factors like family history, physical inactivity, and a diet high in sodium and low in potassium also contribute.
Q: How often should I check my blood pressure? A: If you have high blood pressure, check your blood pressure at home at the same time every day, such as every morning. Take multiple readings and record the results.
Q: Can high blood pressure be prevented? A: Yes, in many cases. Maintaining a healthy weight, being physically active, limiting sodium and alcohol, and not smoking can help prevent high blood pressure.
Q: Is high blood pressure inherited? A: High blood pressure tends to run in families. However, it's caused by a combination of genetic, lifestyle and environmental factors, not a single gene.
Q: How quickly can I lower my blood pressure? A: Lifestyle changes can begin to lower blood pressure within weeks. Medications may start to work within days to weeks. However, high blood pressure is usually a long-term condition that requires ongoing management.
- Conclusion High blood pressure is a common condition that affects millions of people worldwide. Although it's often referred to as a "silent killer" because many people show no symptoms, it can lead to serious health problems if left untreated. The good news is that high blood pressure can often be prevented or controlled through healthy lifestyle choices and, if needed, medication. If you've been diagnosed with high blood pressure, talk to your doctor about the best treatment plan for you.
