Losartan Potassium
Losartan belongs to a group of medicines called angiotensin II receptor antagonists. Angiotensin II is a substance produced in the body that binds to receptors in blood vessel walls, causing them to narrow. This results in an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing blood vessels to widen, which in turn lowers blood pressure. Losartan also slows the progression of kidney disease in patients with high blood pressure and type 2 diabetes.
Loreblok is used:
Before taking Loreblok, discuss with your doctor or pharmacist:
Your doctor may recommend regular monitoring of kidney function, blood pressure, and electrolyte levels (e.g., potassium) in the blood.
See also the subsection "Do not take Loreblok".
You should inform your doctor if you suspect or plan to become pregnant. It is not recommended to take Loreblok during the early stages of pregnancy and it should not be taken after the third month of pregnancy, as it may cause serious harm to the baby (see section "Pregnancy and breastfeeding").
Studies have been conducted on the use of losartan in children. For more information, please consult your doctor. Losartan is not recommended for children with kidney or liver dysfunction, as data on its use in these patient groups are limited. Losartan is not recommended for children under 6 years of age, as its efficacy has not been demonstrated in this age group.
Tell your doctor or pharmacist about all the medicines you are taking, have recently taken, or might take.
Special caution is required when taking the following medicines during treatment with Loreblok:
In the case of kidney dysfunction, concomitant use of these medicines may lead to worsening of kidney function.
Without close medical supervision, you should not take medicines containing lithium in combination with losartan. Special precautions may be necessary (e.g., blood tests).
Loreblok can be taken with or without food.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Your doctor will usually recommend stopping Loreblok before planned pregnancy and will advise you to take a different medicine instead of Loreblok. It is not recommended to take Loreblok during the early stages of pregnancy and it should not be taken after the third month of pregnancy, as it may cause serious harm to the baby.
You should inform your doctor if you are breastfeeding or plan to breastfeed. It is not recommended to take Loreblok during breastfeeding, especially during breastfeeding of a newborn or premature baby. Your doctor may recommend a different medicine.
No studies have been conducted on the effects of Loreblok on the ability to drive or operate machinery.
It is unlikely that Loreblok will affect your ability to drive or operate machinery. However, as with many other blood pressure-lowering medicines, losartan may cause dizziness or drowsiness in some people.
If you experience dizziness or drowsiness, consult your doctor before performing such activities.
Loreblok contains 102 mg of lactose in 50 mg tablets. If you have been told that you have an intolerance to some sugars, contact your doctor before taking this medicine.
Take this medicine exactly as your doctor has told you. If you are not sure, ask your doctor or pharmacist.
Your doctor will determine the appropriate dose of Loreblok, depending on your condition and the other medicines you are taking. It is important to continue taking Loreblok for as long as your doctor has prescribed it in order to maintain consistent blood pressure control.
The recommended dose is:
Patients with high blood pressure
Treatment usually starts with a dose of 50 mg of losartan (one 50 mg tablet) once daily. The maximum blood pressure-lowering effect should occur within 3 to 6 weeks after starting treatment. In some patients, the doctor may then increase the dose to 100 mg of losartan once daily.
If you feel that the effect of losartan is too strong or too weak, consult your doctor or pharmacist.
Patients with high blood pressure and type 2 diabetes
Treatment usually starts with a dose of 50 mg of losartan (one 50 mg tablet) once daily. The doctor may then increase the dose to 100 mg of losartan once daily, depending on the patient's blood pressure changes.
Loreblok can be taken with other blood pressure-lowering medicines (e.g., diuretics, calcium channel blockers, alpha- or beta-blockers) and with insulin and other commonly used medicines that lower blood glucose levels (e.g., sulfonylurea derivatives, glitazones, and glucose inhibitors).
Patients with heart failure
Treatment usually starts with a dose of 12.5 mg of losartan once daily.
Usually, the doctor will gradually increase the dose at weekly intervals (i.e., 12.5 mg daily during the first week, 25 mg daily during the second week, 50 mg daily during the third week) until the usual maintenance dose of 50 mg of losartan (one 50 mg tablet) once daily is reached, depending on the patient's condition.
In the treatment of heart failure, losartan is usually used in combination with diuretics (medicines that increase the amount of water excreted by the kidneys) and/or digitalis glycosides (medicines that strengthen the heart and increase its efficiency) and/or beta-blockers.
The doctor may recommend a lower dose, especially during the initial treatment phase, in certain patients, such as those taking high doses of diuretics, patients with liver dysfunction, or patients over 75 years of age. Losartan should not be taken by patients with severe liver dysfunction (see section "Do not take Loreblok").
Swallow the tablets with a glass of water. Try to take your daily dose at the same time each day. It is important to continue taking Loreblok unless your doctor tells you to stop.
If you have taken more than the prescribed dose of Loreblok or if a child has accidentally taken the medicine, contact your doctor or go to the emergency department of the nearest hospital immediately. Symptoms of overdose are low blood pressure, rapid heartbeat, and possibly slow heartbeat.
If you miss a dose, take the next dose at the usual time. Do not take a double dose to make up for a forgotten tablet.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
