What COZAAR is and what it is used for
Losartan belongs to a group of medicines known as angiotensin-II receptor antagonists.
Angiotensin-II is a substance produced in the body which binds to receptors in blood vessels, causing
them to tighten. This results in an increase in blood pressure. Losartan prevents the binding of
angiotensin-II to these receptors, causing the blood vessels to relax which in turn lowers the blood
pressure. Losartan slows the decrease of kidney function in patients with high blood pressure and type
Losartan is used
to treat patients with high blood pressure (hypertension) in adults and in children and
adolescents 6-18 years of age.
to protect the kidney in hypertensive type 2 diabetic patients with laboratory evidence of
impaired renal function and proteinuria ≥ 0.5 g per day (a condition in which urine contains an
abnormal amount of protein).
to treat patients with chronic heart failure when therapy with specific medicines called
angiotensin-converting-enzyme inhibitors (ACE inhibitors, medicine used to lower high blood
pressure) is not considered suitable by your doctor. If your heart failure has been stabilised with
an ACE inhibitor you should not be switched to losartan.
in patients with high blood pressure and a thickening of the left ventricle, LOSARTAN has been
shown to decrease the risk of stroke (“LIFE indication”).

You must tell your doctor if you think you are (or might become) pregnant. Losartan is not

if you suffer from excessive vomiting or diarrhoea leading to an extreme loss of fluid and/or salt
in your body,
if you receive diuretics (medicines that increase the amount of water that you pass out through
your kidneys) or are under dietary salt restriction leading to an extreme loss of fluid and salt in
your body (see section 3 ‘Dosage in special patient groups’),
if you are known to have narrowing or blockage of the blood vessels leading to your kidneys or
if you have received a kidney transplant recently,
if your liver function is impaired (see sections 2 ‘Do not take Losartan’ and 3 ‘Dosage in special

Other medicines and LOSARTAN
Tell your doctor or pharmacist if you are taking or have recently taken, or might take any other
Take particular care if you are taking the following medicines while under treatment with Losartan:
other blood pressure lowering medicines as they may additionally reduce your blood pressure.
Blood pressure may also be lowered by one of the following drugs/ class of drugs: tricyclic
antidepressants, antipsychotics, baclofen, amifostine,
medicines which retain potassium or may increase potassium levels (e.g. potassium
supplements, potassium-containing salt substitutes or potassium-sparing medicines such as
certain diuretics [amiloride, triamterene, spironolactone] or heparin),
non-steroidal anti-inflammatory drugs such as indometacin, including COX-2-inhibitors
(medicines that reduce inflammation, and can be used to help relieve pain) as they may reduce
the blood pressure lowering effect of losartan.
If your kidney function is impaired, the concomitant use of these medicines may lead to a worsening
of the kidney function.
Lithium containing medicines should not be taken in combination with losartan without close
supervision by your doctor. Special precautionary measures (e.g. blood tests) may be appropriate.
Losartan with food and drink
Losartan may be taken with or without food.
Pregnancy and breast-feeding
You must tell your doctor if you think you are (or might become) pregnant. Your doctor will normally
advise you to stop taking Losartan before you become pregnant or as soon as you know you are
pregnant and will advise you to take another medicine instead of Losartan. Losartan is not
recommended in early pregnancy, and must not be taken when more than 3 months pregnant, as it may
cause serious harm to your baby if used after the third month of pregnancy.
Tell your doctor if you are breast feeding or about to start breast-feeding. Losartan is not
recommended for mothers who are breast-feeding, and your doctor may choose another treatment for
you if you wish to breast-feed. Especially if your baby is a newborn, or born prematurely.

Losartan may be administered with other blood pressure lowering medicines (e.g. diuretics, calcium
channel blockers, alpha- or beta-blockers, and centrally acting agents) as well as with insulin and other
commonly used medicines that decrease the level of glucose in the blood (e.g. sulfonylureas,
glitazones and glucosidase inhibitors).
Adult patients with Heart Failure
Treatment usually starts with 12.5 mg losartan (one tablet losartan 12.5 mg) once a day. Generally, the
dose should be increased weekly step-by-step (i.e., 12.5 mg daily during the first week, 25 mg daily
during the second week, 50 mg daily during the third week, 100 mg daily during the fourth
week, 150 mg daily during the fifth week) up to the maintenance dose as determined by your
physician. A maximum dose of 150 mg losartan (for example, three tablets of losartan 50 mg
or one tablet each of losartan 100 mg and losartan 50 mg) once daily may be used.
In the treatment of heart failure, losartan is usually combined with a diuretic (medicine that increases
the amount of water that you pass out through your kidneys) and/or digitalis (medicine that helps to
make the heart stronger and more efficient) and/or a beta-blocker.
Dosage in special patient groups
The doctor may advise a lower dose, especially when starting treatment in certain patients such as
those treated with diuretics in high doses, in patients with liver impairment, or in patients over the age
of 75 years. The use of losartan is not recommended in patients with severe hepatic impairment (see
section "Do not take Losartan").
The tablets should be swallowed with a glass of water. You should try to take your daily dose at about
the same time each day. It is important that you continue to take Losartan until your doctor tells you
