Question 1

What is Losartan?

Accepted Answer

Losartan is a medication classified as an angiotensin II receptor blocker. It functions by interfering with the action of specific natural substances in the body that cause blood vessels to constrict.

By preventing this narrowing, the medication helps blood vessels relax and widen. This process supports more efficient blood flow and reduces the workload on the heart.

Question 2

What is Losartan used for?

Accepted Answer

Losartan is used to treat:

Hypertension

Diabetic nephropathy in type 2 diabetes mellitus

Reduction of stroke risk in patients with hypertension and left ventricular hypertrophy

Question 3

How does Losartan work?

Accepted Answer

Losartan belongs to a group of medicines known as angiotensin II receptor blockers (ARBs). It works by blocking the action of a natural substance in the body called angiotensin II.

Relaxing Blood Vessels

Angiotensin II is a hormone that causes blood vessels to tighten and narrow. When these vessels are constricted, the heart must work harder to pump blood through them, which increases blood pressure. Losartan prevents angiotensin II from binding to its receptors, which leads to several effects:

Vasodilation: The blood vessels relax and widen.

Lower Blood Pressure: As the vessels widen, blood flows more easily, and blood pressure decreases.

Reduced Strain: A lower blood pressure reduces the workload on the heart, making it easier for the heart to pump blood throughout the body.

Kidney Protection

For individuals with type 2 diabetes and high blood pressure, losartan also helps protect the kidneys. By improving blood flow and reducing pressure within the filtering units of the kidney, it can slow down the progression of kidney damage caused by these conditions.

What is the dosage of Losartan and how do I take it?

Accepted Answer

How to Take Losartan

Losartan comes as a tablet to be taken by mouth. It is usually taken once or twice a day. To help you remember your medication, try to take it at the same time every day.

With or without food: You may take this medication with or without food.

Consistency: It is important to take this medication regularly, even if you feel well. Most people with high blood pressure do not feel sick.

Liquid form: If you are using a liquid version of this medication, shake the bottle well before measuring your dose. Use a proper measuring device rather than a household spoon to ensure the correct amount is taken.

Missed Dose

If you miss a dose, 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 two doses at once to make up for a missed one.

Question 9

Is Losartan safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Losartan carries a boxed warning because it can cause serious injury or death to an unborn baby if taken during pregnancy. The risks are highest during the second and third trimesters. Potential complications for the fetus include:

Kidney failure

Low levels of amniotic fluid

Deformities of the skull, face, or limbs

Underdeveloped lungs

If you become pregnant while taking losartan, you should stop the medication and contact your healthcare provider immediately. Most doctors will switch patients to a safer blood pressure medication if they are planning to become pregnant or find out they are pregnant.

Breastfeeding

It is not known if losartan passes into human breast milk. Because the drug could potentially cause serious side effects in a nursing infant, healthcare providers usually recommend either discontinuing the medication or stopping breastfeeding. You should consult with your doctor to determine the best option based on your medical needs and the importance of the medication for your health.

Question 10

What forms and strengths does Losartan come in?

Accepted Answer

Losartan is manufactured in the following oral forms:

Oral Tablet: This medication is taken by mouth.

Combination Oral Tablet: Losartan is also available in a single tablet combined with other medications, such as diuretics, to treat high blood pressure.

Question 11

What is the FDA approval status of Losartan?

Accepted Answer

FDA Approval and Indications

Losartan was first approved by the U.S. Food and Drug Administration (FDA) in 1995. It is approved for the following indications:

Hypertension: To lower high blood pressure in adults and children 6 years of age and older.

Diabetic Nephropathy: To treat kidney disease in patients with type 2 diabetes and a history of hypertension.

Stroke Risk Reduction: To reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy (thickening of the heart's left ventricle).

Boxed Warning

Losartan carries a boxed warning regarding fetal toxicity. Drugs that act on the renin-angiotensin system can cause injury and death to a developing fetus when used during the second and third trimesters of pregnancy. Healthcare providers recommend discontinuing the medication as soon as pregnancy is detected.

Safety Communications and Recalls

The FDA has issued safety communications regarding the use of losartan in combination with other drugs. It is contraindicated for use with aliskiren in patients with diabetes. Using losartan with ACE inhibitors or other similar blood pressure medications may increase the risk of kidney impairment, high potassium levels, and severely low blood pressure.

There have been historical voluntary recalls of certain generic losartan products due to the presence of nitrosamine impurities, which are potential human carcinogens. The FDA monitors these levels to ensure patient safety, and patients are advised not to stop taking their medication without consulting a doctor, as untreated high blood pressure carries significant risks.

Question 12

What should I know about Losartan and cost?

Accepted Answer

Generic Availability

Losartan is the generic version of the brand-name drug Cozaar. Generic medications are required to have the same active ingredients, strength, and effectiveness as brand-name drugs, but they are usually sold at a significantly lower price.

Insurance Coverage

Most health insurance plans, including Medicare Part D and Medicaid, cover generic losartan. Because it is a common generic medication, it is often categorized in the lowest cost-sharing tier of insurance formularies, meaning patients typically pay the lowest possible co-pay.

Factors Affecting Cost

The actual price of losartan can vary based on several factors:

Dosage and Quantity: The strength of the tablet (25 mg, 50 mg, or 100 mg) and the number of pills dispensed (such as a 30-day versus a 90-day supply) will impact the total cost.

Formulation: Losartan is available as a single-ingredient medication or in combination with other drugs, such as hydrochlorothiazide. Combination products may have different pricing than losartan alone.

Pharmacy Selection: Prices may differ between retail pharmacies, mail-order services, and independent drugstores.

For those without insurance, many pharmacies include generic losartan in their discount programs, which may offer the medication at a fixed, low out-of-pocket cost.
