Cozaar: Uses, Mechanism, and Approved Indications

Cozaar, also known as losartan, is an angiotensin receptor blocker (ARB) medication used to treat high blood pressure (hypertension) and help protect the kidneys from damage due to diabetes. It works by relaxing blood vessels, allowing blood to flow more easily and lowering blood pressure. Cozaar is also approved to lower the risk of strokes in patients with high blood pressure and an enlarged heart.

Dosage and Administration of Cozaar

Cozaar is typically taken orally, once daily, with or without food. The dosage is determined based on the patient’s medical condition and response to treatment. For the liquid formulation, it is important to shake the bottle well before each use and carefully measure the dose using the provided special measuring device or spoon, as household spoons may not deliver the correct amount. Patients should take Cozaar regularly to get the maximum benefit, and continue using it even if they feel well, as high blood pressure often has no symptoms.

Potential Side Effects of Cozaar

The most common side effects of Cozaar are dizziness and lightheadedness, which may occur as the body adjusts to the medication. These effects are usually mild and transient. More serious side effects, such as fainting, symptoms of high potassium levels, and changes in kidney function, should be reported to the healthcare provider immediately. Patients may also experience a rare but severe allergic reaction, which requires prompt medical attention.

Precautions and Contraindications for Cozaar

Cozaar should not be used during pregnancy, as it can cause serious harm to the developing fetus. Patients should use reliable birth control methods while taking this medication and contact their healthcare provider if they are planning pregnancy, become pregnant, or suspect they may be pregnant. Cozaar may also increase potassium levels, so patients with a history of liver disease, dehydration, or high potassium levels should inform their healthcare provider before starting this medication. Patients should avoid driving or operating machinery until they know how Cozaar affects them, as it may cause dizziness or drowsiness.

Drug Interactions with Cozaar

Cozaar may interact with certain medications, supplements, or substances. Patients should inform their healthcare provider of all the medications, vitamins, and supplements they are taking, including over-the-counter products. Alcohol and marijuana (cannabis) may increase the risk of dizziness and lightheadedness when used in combination with Cozaar.

Monitoring and Follow-up for Cozaar Therapy

Patients taking Cozaar should have their blood pressure, kidney function, and potassium levels monitored regularly by their healthcare provider. If the condition does not improve or worsens, the healthcare provider should be notified. Patients should also report any new or worsening side effects to their provider promptly.

Why is Cozaar Prescribed?

Cozaar is prescribed to treat high blood pressure (hypertension) and help protect the kidneys from damage due to diabetes. It is also used to lower the risk of strokes in patients with high blood pressure and an enlarged heart. By lowering high blood pressure, Cozaar helps prevent the development of serious cardiovascular and kidney problems.

How Does Cozaar Work?

Cozaar, or losartan, belongs to a class of drugs called angiotensin receptor blockers (ARBs). It works by blocking the action of angiotensin II, a hormone that constricts blood vessels and increases blood pressure. By inhibiting the effects of angiotensin II, Cozaar allows blood vessels to relax and blood to flow more easily, leading to a reduction in blood pressure.

Cozaar Dosage Forms and Strengths

Cozaar is available in tablet and oral solution formulations. The tablet strengths include 25 mg, 50 mg, and 100 mg. The oral solution is available in a concentration of 2.5 mg/mL. The dosage is determined by the healthcare provider based on the patient’s medical condition and response to treatment.

Storage and Handling of Cozaar

Cozaar tablets should be stored at room temperature, away from light, heat, and moisture. The oral solution formulation should be stored in the original container and protected from light. Patients should keep Cozaar out of the reach of children and pets.

Is Cozaar a Safe Medication?

Cozaar is generally well-tolerated, but like any medication, it can cause side effects. Most side effects are mild and transient, such as dizziness and lightheadedness. However, more serious side effects, like changes in kidney function or high potassium levels, can occur. Patients should inform their healthcare provider of any new or worsening side effects and follow their provider’s recommendations for monitoring and managing the medication.

Cozaar and Pregnancy

Cozaar should not be used during pregnancy, as it can cause serious harm to the developing fetus. Patients who are planning pregnancy, become pregnant, or suspect they may be pregnant while taking Cozaar should contact their healthcare provider immediately. Alternative medications may be necessary to manage high blood pressure or kidney disease during pregnancy.

Cozaar and Breastfeeding

It is not known if Cozaar is excreted in breast milk. Therefore, healthcare providers may recommend alternative treatments or advise against breastfeeding while taking this medication, as the potential risks to the nursing infant are unknown.

Cozaar and Overdose

In the event of a Cozaar overdose, patients should seek immediate medical attention. Symptoms of a Cozaar overdose may include low blood pressure, dizziness, and changes in kidney function. Healthcare providers can provide appropriate treatment and monitoring to manage the overdose.

Cozaar Alternatives and Substitutes

If Cozaar is not tolerated or is not effective in managing a patient’s condition, healthcare providers may consider alternative medications, such as other angiotensin receptor blockers (ARBs), angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers, or diuretics. The choice of medication will depend on the patient’s specific medical needs and the healthcare provider’s clinical judgment.

Cozaar and Cardiovascular Disease

Cozaar is approved to lower the risk of strokes in patients with high blood pressure and an enlarged heart. By effectively lowering blood pressure, Cozaar can help reduce the strain on the cardiovascular system and prevent the development of serious cardiovascular complications, such as heart attacks and strokes.

Cozaar and Kidney Disease

Cozaar is also used to help protect the kidneys from damage due to diabetes. By controlling blood pressure and inhibiting the effects of angiotensin II, Cozaar can help slow the progression of diabetic kidney disease and preserve kidney function in patients with both high blood pressure and diabetes.

Cozaar and Geriatric Patients

Older adults may be more sensitive to the effects of Cozaar, particularly the risk of dizziness and lightheadedness. Healthcare providers may need to adjust the dosage or closely monitor geriatric patients taking this medication to ensure their safety and well-being.

Cozaar and Pediatric Patients

The safety and efficacy of Cozaar in children have not been fully established. Healthcare providers may consider using Cozaar in pediatric patients on a case-by-case basis, based on the child’s specific medical needs and the potential benefits and risks of the medication.

Cozaar and Renal Impairment

Patients with impaired kidney function may require dosage adjustments or closer monitoring when taking Cozaar, as the medication can affect kidney function. Healthcare providers should carefully evaluate the patient’s kidney function and adjust the Cozaar dosage accordingly.

Cozaar and Hepatic Impairment

Patients with liver disease may also require dosage adjustments or closer monitoring when taking Cozaar, as the medication is metabolized by the liver. Healthcare providers should assess the patient’s liver function and adjust the Cozaar dosage as needed.

Cozaar and Long-Term Use

Cozaar is typically a long-term medication used to manage high blood pressure and protect the kidneys from damage due to diabetes. Patients may need to take Cozaar for an extended period, and it is important to follow the healthcare provider’s instructions and continue taking the medication as prescribed, even if the patient feels well.

Cozaar and Generic Availability

Cozaar, the brand-name formulation of losartan, is available in generic versions. Generic losartan is typically more affordable than the brand-name product, but the healthcare provider will determine the most appropriate form of the medication for the patient’s needs.

Cozaar and Patient Assistance Programs

Patients who are struggling to afford Cozaar or other medications may be eligible for patient assistance programs offered by the pharmaceutical company or other organizations. These programs can help provide access to Cozaar and other necessary medications for those who meet certain financial or other eligibility criteria.

Cozaar and Complementary Therapies

While Cozaar is the primary treatment for high blood pressure and diabetic kidney disease, some patients may choose to incorporate complementary therapies, such as lifestyle changes or herbal supplements, into their overall management plan. Patients should always consult their healthcare provider before adding any complementary therapies, as they may interact with Cozaar or other medications.

Cozaar and Patient Education

It is important for patients taking Cozaar to understand the medication’s purpose, dosage, side effects, and potential interactions. Healthcare providers should provide clear instructions and educational resources to help patients manage their Cozaar therapy effectively and safely.

Cozaar and Medication Adherence

Consistent and proper use of Cozaar is essential for its effectiveness in managing high blood pressure and protecting the kidneys. Patients should take Cozaar as prescribed and contact their healthcare provider if they have any questions or concerns about their medication regimen.

Cozaar and Healthcare Provider Communication

Patients should keep their healthcare providers informed about any changes in their medical condition, new symptoms, or other medications they are taking, as this information can help ensure the safe and effective use of Cozaar.

Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about COZAAR. It does not contain all
the available information. It does not take the place of talking to your doctor or
pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking
COZAAR against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine.

You may need to read it again.

What COZAAR is used for

COZAAR lowers high blood pressure, which doctors call hypertension.

COZAAR is also used to slow the progression of kidney disease in people who have type
2 diabetes mellitus (also known as non-insulin dependent diabetes) with protein in
their urine (which doctors call proteinuria).

Hypertension:

Everyone has blood pressure. This pressure helps get your blood all around your body.
Your blood pressure may be different at different times of the day, depending on how
busy or worried you are. You have hypertension (high blood pressure) when your blood
pressure stays high, even when you are calm and relaxed.

There are usually no symptoms of hypertension. The only way of knowing that you have
hypertension is to have your blood pressure checked on a regular basis. If high blood
pressure is not treated it can lead to serious health problems. You may feel fine
and have no symptoms, but eventually hypertension can cause stroke, heart disease
or kidney failure. COZAAR helps to lower your blood pressure.

Type 2 Diabetes Mellitus:

Type 2 diabetes mellitus is a condition in which the body’s cells do not respond to
the effects of insulin or too little insulin is produced, resulting in an elevated
blood (sugar) level, known as hyperglycaemia.

Insulin maintains the appropriate level of glucose in the blood by transporting it
into the body’s cells so that they can produce energy or store glucose until it’s
needed.

Hyperglycaemia can lead to serious problems with your heart, eyes, circulation or
kidneys. When kidney damage occurs, its ability to filter blood is reduced, and proteins
in the blood are lost in the urine. This may eventually lead to kidney failure.
In people who have type 2 diabetes mellitus with protein in their urine, COZAAR helps
to slow the worsening of kidney disease and reduce the need for dialysis or kidney
transplantation.

How it works

COZAAR belongs to a group of medicines, called angiotensin II receptor antagonists.
It works to lower your blood pressure by relaxing your blood vessels. In addition,
COZAAR slows the progression of kidney disease in people who have type 2 diabetes
mellitus with protein in the urine.

COZAAR is not addictive.

Before you take COZAAR

When you must not take it

Do not take COZAAR if:

you are pregnant or breast-feeding

The use of COZAAR while you are pregnant or breast-feeding is not recommended. Your
baby may absorb this medicine in the womb. COZAAR can cause harm or death to an unborn
baby. Talk to your doctor about other ways to lower your blood pressure if you plan
to become pregnant. If you get pregnant while taking COZAAR tell your doctor right
away. It is not known whether COZAAR passes into breast milk, therefore it is not
recommended to be taken while you are breast-feeding.

you have an allergy to COZAAR or any of the ingredients listed at the end of this
leaflet

you have diabetes and are taking a medicine called aliskiren to reduce blood pressure.

the packaging is torn or shows signs of tampering

the expiry date on the pack has passed.

If you take this medicine after the expiry date has passed, it may not work.

If you are not sure whether you should start taking COZAAR, talk to your doctor.

Do not give COZAAR to a child.

There is no experience with the use of COZAAR in children.

Before you start to take it

Tell your doctor if:

1. you intend to become pregnant or plan to breast-feed

COZAAR should not be used during pregnancy or while breast-feeding.

2. you are taking other medicines that may increase serum potassium (see Taking other
medicines).

3. you have any medical conditions, especially the following:

kidney disease

liver problems or have had these in the past.

4. you have recently had excessive vomiting or diarrhoea

5. you have any allergies to any other medicines or any other substances, such as foods,
preservatives or dyes.

If you have not told your doctor about any of the above, tell them before you take
any COZAAR.

Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you
buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines or substances and COZAAR may interfere with each other. These include:

Other blood pressure medicines

diuretic tablets, also called fluid or water tablets, including potassium-sparing
diuretics

potassium tablets

potassium-containing salt substitutes

other medicines that may increase serum potassium (e.g., trimethoprim-containing products).

medicines used to relieve pain, swelling, and other symptoms of inflammation, for
example, indomethacin.

lithium (a medicine used to treat mood swings and some types of depressions)

grapefruit juice (which should be avoided while taking COZAAR)

These medicines may have an additive effect with COZAAR in lowering your blood pressure,
or may affect how well it works, or may lead to increases in potassium in your blood.
You may need to take different amounts of your medicine, or you may need to take different
medicines.

Your doctor or pharmacist has more information on medicines to be careful with or
avoid while taking COZAAR.

How to take COZAAR

How much to take

Your doctor will tell you how many tablets you need to take each day. This depends
on your condition and whether you are taking other medicines. Take COZAAR only when
prescribed by your doctor.

For high blood pressure:

For most patients, the usual starting dose is one 50 mg tablet taken once a day.
Some patients may need a lower starting dose. The dose may need to be increased depending
on your blood pressure. Most patients take between 25 to 100 mg each day, taken as
a single dose or in divided doses.

For type 2 diabetes mellitus with protein in the urine:

The usual starting dose is one 50 mg tablet taken once a day. The dose may be increased
to 100 mg once a day depending on your blood pressure.

Follow all directions given to you by your doctor carefully. They may differ from
the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist
for help.

When to take it

Take your COZAAR at about the same time each day.

Taking your tablet(s) at the same time each day will have the best effect. It will
also help you remember when to take the tablets.

Swallow COZAAR with a glass of water.

It does not matter whether you take COZAAR before or after food.

How long to take it

COZAAR helps control your high blood pressure, but does not cure it. Therefore COZAAR
must be taken every day. Continue taking COZAAR for as long as your doctor prescribes.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next
dose when you are meant to. Otherwise, take it as soon as you remember, and then
go back to taking your tablet(s) as you would normally.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

Do not take a double dose to make up for the dose that you missed.

If you have trouble remembering to take your tablets, ask your pharmacist for some
hints.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26),
or go to accident and emergency at your nearest hospital, if you think that you or
anyone else may have taken too much COZAAR. Do this even if there are no signs of
discomfort or poisoning.

If you take too many tablets, you will probably feel light-headed or dizzy.

While you are using COZAAR

Things you must do

If you become pregnant while taking COZAAR, tell your doctor immediately.

Your doctor needs to know immediately so that COZAAR can be replaced by another medicine.

Have your blood pressure checked when your doctor says, to make sure COZAAR is working.

If you are about to be started on any new medicine, tell your doctor and pharmacist
that you are taking COZAAR.

If you feel light-headed, dizzy or faint, get up slowly when getting out of bed or
standing up.

You may feel light-headed or dizzy while taking COZAAR, especially if you are also
taking a diuretic (fluid tablet). This may become worse if you stand up quickly as
your blood pressure may fall. Standing up slowly, especially when you get up from
bed or chairs, will help your body get used to the change in position and blood pressure.
This problem is not common. If it occurs and gets worse or continues, talk to your
doctor.

If you plan to have surgery (even at the dentist) that needs a general anaesthetic,
tell your doctor or dentist that you are taking COZAAR.

Make sure you drink enough water during exercise and hot weather when you are taking
COZAAR, especially if you sweat a lot.

If you do not drink enough water while taking COZAAR, you may faint or feel light-headed
or sick. This is because your body doesn’t have enough fluid and your blood pressure
is low. If you continue to feel unwell, tell your doctor.

If you have excessive vomiting and/or diarrhoea while taking COZAAR, tell your doctor.

This can also mean that you are losing too much water and your blood pressure may
become too low.

If your doctor has prescribed potassium tablets for you, continue taking them.

COZAAR contains a very small amount of potassium, but this does not replace any potassium
tablets that you may be taking.

Go to your doctor regularly for a check-up.

Your doctor may occasionally do a blood test to check your potassium level in the
blood and to see how your kidneys are working.

Things you must not do

Do not give COZAAR to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful driving or operating machinery until you know how COZAAR affects you.

As with many other medicines used to treat high blood pressure, COZAAR may cause dizziness
or light-headedness in some people. Make sure you know how you react to COZAAR before
you drive a car, operate machinery, or do anything else that could be dangerous if
you are dizzy or light-headed. If you drink alcohol, dizziness or light-headedness
may be worse.

Things that would be helpful for your blood pressure

Some self-help measures suggested below may help your condition. Talk to your doctor
or pharmacist about these measures and for more information.

Alcohol –

your doctor may advise you to limit your alcohol intake.

Diet –

eat a healthy diet which includes plenty of fresh vegetables, fruit, bread, cereals
and fish. Also eat less fat and sugar.

Exercise –

regular exercise helps to reduce blood pressure and helps the heart get fitter, but
it is important not to overdo it. Walking is good exercise, but try to find a route
that is fairly flat. Before starting any exercise, ask your doctor about the best
kind of programme for you.

Salt –

your doctor may advise you to watch the amount of salt in your diet. To reduce your
salt intake you should avoid using salt in cooking or at the table.

Smoking –

your doctor may advise you to stop smoking or at least cut down.

Weight –

your doctor may suggest losing some weight to help lower your blood pressure and help
lessen the amount of work your heart has to do. Some people may need a dietician’s
help to lose weight.

Side Effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you
are taking COZAAR.

COZAAR helps most people with high blood pressure, but it may have unwanted side effects
in a few people. All medicines can have side effects. Sometimes they are serious,
most of the time they are not. You may need medical treatment if you get some of
the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you notice any of the following and they worry you:

dizziness

lightheadedness

tiredness or weakness

spinning sensation

generally feeling unwell

increased sensitivity of the skin to sun

inability to get or maintain an erection

These are the common side effects of COZAAR. For the most part these have been mild.

Also, tell your doctor if you develop cough.

Tell your doctor immediately if you notice any of the following:

skin rash, itchiness

aching muscles, not caused by exercise

signs of anaemia, such as tiredness, being short of breath, and looking pale

bleeding or bruising more easily than normal

These may be serious side effects. Skin rash and itchiness may be symptoms of an
allergic reaction. You may need medical attention. These side effects are not common.

If any of the following happen, stop taking COZAAR and tell your doctor immediately
or go to accident and emergency at your nearest hospital:

swelling of the face, lips, mouth, tongue or throat which may cause difficulty in
swallowing or breathing

severe and sudden onset of pinkish, itchy swellings on the skin, also called hives
or nettlerash

These are serious side effects. If you have them, you may have had a serious allergic
reaction to COZAAR. You may need urgent medical attention or hospitalisation. These
side effects are rare.

Other side effects not listed above may also occur in some patients. Tell your doctor
if you notice any other effects.

Do not be alarmed by this list of possible side effects. You may not experience any
of them.

After using COZAAR

Storage

Keep your tablets in the blister pack until it is time to take them.

If you take the tablets out the blister pack they may not keep well.

Keep it in a cool dry place where the temperature stays below 30°C. Do not store it
or any other medicine in the bathroom or near a sink.

Do not leave it in the car or on window sills.

Heat and dampness can destroy some medicines.

Keep it where children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place
to store medicines.

Disposal

If your doctor tells you to stop taking COZAAR or the tablets have passed their expiry
date, ask your pharmacist what to do with any that are left over.

Pharmacotherapeutic group:

Angiotensin II receptor antagonist

Pharmacological action

Antihypertensive agent. It is a non-peptide blocker of angiotensin II receptors. It has a high selectivity and affinity for AT 1 type receptors (with the participation of which the main effects of angiotensin II are realized). By blocking these receptors, losartan prevents and eliminates the vasoconstrictive effect of angiotensin II, its stimulating effect on the secretion of aldosterone by the adrenal glands, and some other effects of angiotensin II. It is characterized by a long action (24 hours or more), which is due to the formation of its active metabolite.

Pharmacokinetics

After oral administration, losartan is rapidly absorbed from the gastrointestinal tract. Bioavailability is about 33%. It is metabolized during the “first pass” through the liver with the formation of a carboxyl metabolite, which has a more pronounced pharmacological activity than losartan, and a number of inactive metabolites. C max in blood plasma of losartan and the active metabolite is achieved after 1 hour and 3-4 hours, respectively. Plasma protein binding of losartan and the active metabolite is high – more than 98%.

T 1/2 losartan and the active metabolite in the final phase is about 1.5-2.5 hours and 3-9 hours, respectively. Losartan is excreted in the urine and feces (with bile) unchanged and as metabolites. About 35% is excreted in the urine and about 60% in the feces.

Indications of the active substances of the drug

Contraindications for use

Pregnancy, lactation, children and adolescents under 18 years of age, hypersensitivity to losartan.

Use in pregnancy and lactation

Contraindicated in pregnancy and lactation.

Use in hepatic impairment

In patients with a history of liver disease, low doses of losartan should be used. With cirrhosis of the liver, the concentration of losartan in the blood plasma increases significantly.

Use in impaired renal function

Renal impairment may require dose reduction of losartan.

Use in children

The safety and efficacy of losartan in children have not been established.

Use in elderly patients

In elderly patients during the treatment period, the level of potassium in the blood should be regularly monitored.

Precautions

Use with caution in arterial hypotension, decreased BCC, fluid and electrolyte imbalance, bilateral renal artery stenosis or arterial stenosis of a solitary kidney, in renal / hepatic insufficiency

Patients who are deficient in fluid and/or sodium should have their fluid and electrolyte disturbances corrected before starting treatment or use a lower initial dose.

In patients with dehydration (eg, treated with high dose diuretics), symptomatic hypotension may occur at the start of treatment with losartan.

Renal impairment may require dose reduction of losartan.

In patients with a history of liver disease, losartan should be used at low doses. With cirrhosis of the liver, the concentration of losartan in the blood plasma increases significantly.

During the period of treatment, the level of potassium in the blood should be regularly monitored, especially in elderly patients, with impaired renal function.

Concomitant use of losartan with potassium-sparing diuretics should be avoided.

The safety and efficacy of losartan in children have not been established.

Drug interactions

When used simultaneously with diuretics in high doses, arterial hypotension is possible.

When used simultaneously with potassium preparations, potassium-sparing diuretics, the risk of developing hyperkalemia increases.

Co-administration with indomethacin may reduce the effectiveness of losartan.

There is a report of the development of lithium intoxication with simultaneous use with lithium carbonate.

When used simultaneously with orlistat, the antihypertensive effect of losartan decreases, which can lead to a significant increase in blood pressure, the development of a hypertensive crisis.

With simultaneous use with rifampicin, the clearance of losartan increases and its effectiveness decreases.
