Losartan 100mg

What Is Losartan 100mg

Losartan 100mg is a prescription medicine used to treat high blood pressure (hypertension) and to protect the heart and kidneys in certain patients. High blood pressure means the force of blood pushing against artery walls stays too high for a long time, which can damage important organs.

Doctors prescribe Losartan 100mg tablets when lower doses are not enough to control blood pressure or when stronger long-term control is needed.

This medicine belongs to a group called angiotensin II receptor blockers (ARBs). These medicines help relax blood vessels so blood can flow more easily.

Cardiologists and physicians commonly use Losartan tablets for long-term management of blood pressure and heart health protection. A cardiologist is a specialist doctor who treats heart and circulation problems.

The medicine is usually taken once daily and is meant for continuous long-term use under medical supervision.

What This Medicine Does in the Body

Losartan 100mg works by blocking a natural chemical in the body called angiotensin II.

Angiotensin II is a hormone that makes blood vessels tighten and become narrow. When this happens, blood pressure increases and the heart has to work harder.

Losartan tablets block the action of this hormone. This allows blood vessels to relax and stay open.

When blood vessels are relaxed, blood flows more smoothly, and blood pressure gradually decreases.

This reduces stress on the heart and helps protect important organs like the brain, kidneys, and blood vessels from long-term damage.

The medicine also helps reduce fluid and salt retention in the body, which further supports blood pressure control.

Because of its steady action, Losartan 100mg is widely used for long-term blood pressure management rather than immediate relief.

Uses of Losartan 100mg / Losartan 100mg Used For

Doctors mainly prescribe Losartan 100mg for the treatment of high blood pressure (hypertension). Controlling blood pressure helps reduce the risk of serious complications like heart attack, stroke, and kidney damage.

Cardiologists also use Losartan tablets in patients with heart failure to reduce strain on the heart and improve its pumping ability.

The medicine is also prescribed to protect kidney function in some patients, especially those with diabetes-related kidney disease.

In certain cases, Losartan 100mg may be used after a heart attack to support heart recovery and reduce future risks.

Doctors usually include this medicine as part of a long-term treatment plan along with lifestyle changes such as a low-salt diet, regular exercise, weight control, and avoiding smoking.

How Losartan 100mg Work

Losartan 100mg works by blocking angiotensin II receptors in the body.

Angiotensin II normally causes blood vessels to tighten and raises blood pressure. It also increases salt and water retention, which can further increase pressure in the blood vessels.

Losartan tablets prevent this hormone from attaching to its receptors.

As a result, blood vessels relax and widen. This improves blood flow and gradually lowers blood pressure.

Lower blood pressure reduces strain on the heart and helps protect long-term heart and kidney health.

Doctors usually recommend taking Losartan 100mg once daily at the same time each day for consistent control.

Stopping the medicine suddenly without medical advice may cause blood pressure to rise again.

Side Effects of Losartan 100mg

Like all medicines, Losartan 100mg may cause side effects in some people. Most side effects are mild and may improve as the body adjusts.

Common side effects include dizziness, headache, tiredness, and mild weakness. Dizziness may be more noticeable when standing up quickly.

Some patients may experience low blood pressure, which can cause lightheadedness or fainting in rare cases.

In some cases, Losartan tablets may affect kidney function or change potassium levels in the blood. Potassium is an important mineral that helps regulate heart rhythm.

Rare but serious side effects include severe allergic reactions, swelling of the face or throat, or significant kidney-related problems.

Doctors may monitor blood pressure, kidney function, and electrolyte levels during treatment to ensure safe use.

Patients should inform their doctor if they have kidney disease, liver disease, or dehydration before starting Losartan 100mg.
