Uses

indications

Hyzaar® drug is indicated in the following cases:

  • High blood pressure: Hyzaar® is used to treat hypertension in patients suitable for this combination treatment. In people with high blood pressure and left ventricular hypertrophy, Losartan is often coordinated with hydrochlorothiazide, reducing the risk of cardiovascular diseases and deaths due to these diseases such as the general rate of cardiovascular death, stroke and myocardial infarction in people with high blood pressure with left ventricular hypertrophy. Hydrochlorothiazide

    The components of Hyzaar® have proved to have additional effects in hypotension, reducing blood pressure better than each separate ingredient. This effect is thought to be the result of the mutual support effects of both components. Moreover, due to the diuretic effect, hydrochlorothiazide increases the activity of plasma rennin, increases the secretion of aldosterone, reduces serum potassium, and increases angiotensin II levels. Using Losartan will prevent all the physiological effects of Angiotensin II and through Aldosterone inhibitors may tend to lose potassium associated with this diuretic.

    Losartan has been shown to increase urinary uric acid at a light and transient level. Hydrochlorothiazide has been shown to cause a little increase in uric acid; The combination of Losartan and Hydrochlorothiazide tends to reduce hyperuricemia due to the effect of this diuretic.

    Use combinations of Losartan and Hydrochlorothiazide increases anti -blood pressure effect

    Hyzaar®'s anti -blood pressure effect is maintained for 24 hours. In clinical studies that last for at least one year, the effectiveness of high blood pressure treatment is guaranteed to be maintained with continuous therapy. Despite significantly reducing blood pressure, the use of Hyzaar® does not have a significant clinical impact on the heart rate. In clinical studies, after 12 weeks of treatment with Lostartan 50mg/Hydrochlorothiazide 12.5mg, diastolic blood pressure drops to an average of 13.2mmHg.

    Hyzaar® effectively reduces blood pressure in both men and women, black people and other races and even in young people ( losartan

    Losartan is an Angiotensin II receptor inhibitor (Type AT1) orally. Angiotensin II is linked to AT1 receptors that are found in many tissues (such as vascular smooth muscles, adrenal glands, kidneys and hearts) and promote many important biological activities, including vascular contractions and aldosterone secretions. Angiotensin II also stimulates smooth muscle cell proliferation. On the basis of cohesion and pharmacological biological tests, Angiotensin II selectively linked with AT1 receptors. In Vitro and In Vivo, both Losartan and carboxylic acid metabolites have its pharmacological activity (E-3174) blocking all related physiological activities of Angiotensin II, regardless of the source and synthetic root.

    During the use of losartan, the elimination of negative response of angiotensin for Rennin secretion will lead to increased rennin activity in plasma. Increased rennin activity in plasma leads to an increase in angiotensin II in plasma. Even with these phenomena, the anti -hypertension activity and restraint of plasma Aldosterone levels are still maintained, showing the ability to blockage through the Angiotensin II receptor.

    Losartan is selected with AT1 receptor and does not bind or blocked other hormones or other ion exchange channels that play an important role in the cardiovascular regulation. Moreover, Losartan does not inhibit ACE (Kininase II) - the enzyme degenerate Bradykinin. Therefore, the impacts that are not directly related to the AT1 receptor blockage, such as the potential of affecting Bradykinin intermediaries or edema (Losartan 1.7%, Placebo 1.9%), is not related to Losartan.

    Losartan has been shown to prevent response to Angiotensin I and Angiotensin II without affecting Bradykinin response, this is a unified finding with a typical operation mechanism of Losartan. On the contrary, ACE transferred enamel inhibitors have been shown to prevent response to angiotensin and strengthen the response to Bradykinin without changing the response to Angiotensin II, which is a sign of pharmacological distinction between Losartan and ACE transfer enamel inhibitors.

    In patients with high blood pressure without diabetes with protein - urinary, the use of potassium Losartan significantly reduces protein - urinary, excreting albumin and IgG. Losartan maintains glomerular filtration speed and reduces filtration fraction. Overall, Losartan causes a decrease in serum uric acid (usually

    Losartan does not work on automatic reflexes and does not work on plasma norepinephrine, in patients with left ventricular impairment, dose 25mg and 50mg Losartan have a positive effect on hemodynamics and nervous nerves typical by increased cardiac index and decrease in pulmonary capillary pressure, system resistance, medium system pressure and heart rate, decrease in the level of weekly. Hypertension is dependent on the dose used in patients with this heart failure.

    Use Losartan 50 - 100mg once a day has a significantly higher hypotension than Captopril 50 - 100mg used once a day. The hypotension effect of Losartan 50mg is the same as the enalapril 20mg used once a day. The hypotension effect of Losartan 50 - 100mg once daily is equivalent to Atenolol 50 - 100mg used once a day. The effect of Losartan 50 - 100mg once daily is equivalent to Felodipine 5 - 10mg for prolonged release when used in patients with elderly high blood pressure (≥ 65 years) after 12 weeks of treatment.

    Losartan is equally effective in patients with high blood pressure for men and women and in young people (

    hydrochlorothiazide

    The mechanism of hypotension of the Thiazide group is not known. Thiazide usually does not have the effect of normal blood pressure.

    Hydrochlorothiazide is a diuretic and hypotension. Effects on electrolyte reabsorption mechanism in the distance. Hydrochlorothiazide increases the excretion of sodium and chloride at approximately equal. Sodium - urinary, may be accompanied by a loss of potassium and bicarbonate.

    After oral use, the first diuretics work after 2 hours, peak after about 4 hours and last for about 6 - 12 hours

    Dynamic pharmacokinetics

    absorption

    losartan

    After oral use, Losartan is absorbed well and undergo the first metabolic stage to form a metabolic carboxylic acid metabolism and other inactive metabolites. Losartan's whole body bioavailability is approximately 33%. The average peak concentration is achieved after 1 hour (Losartan) and 3-4 hours (active metabolites). No significant clinical effect on Losartan's plasma concentrations when this drug is used with the same standard meal.

    distribution

    losartan

    Both Losartan and active metabolites are bound ≥ 99% with plasma proteins, mainly albumin. Losartan distribution volume is 34 liters. Rat studies show that Losartan through cerebral blood membrane is very few, not even.

    hydrochlorothiazide

    Hydrochlorothiazide passes through the placenta but does not pass the cerebral blood, and is secreted into breast milk.

    Metabolism

    losartan

    About 14% of Losartan dose using intravenous or oral line is converted into activated metabolites. After oral or oral use, Losartan Kali has a 14C marker, radioactive activity in circulating plasma is attributed to Losartan and its active metabolites. The minimum conversion of Losartan into active metabolites is seen in about 1% of the research individual.

    In addition to active metabolites, it also forms inactivated metabolites, there are two main metabolites formed by the hydroxylation of the Butyl edge chain and a small metabolic substance is a glucuronide N-2-Tetrazole.

    Elimination

    losartan

    Losartan's plasma clearance is about 600ml/min and its active metabolites are 50ml/minute. The kidney clearance of Losartan is about 74ml/min and its active metabolites are 26ml/min. When using losartan oral, about 4% dose is secreted in urine in a constant form, and about 6% of the dose is secreted in urine in the form of active metabolites. The pharmacokinetics of Losartan and its active metabolites are linear with Losartan Kali oral at less doses to 200mg.

    After oral use, Losartan's plasma concentration and its metabolites decrease many times with the end of the end of the end of the end of the end of about 2 hours (Losartan) and 6 - 9 hours (its transformation). While taking Losartan dose every 100mg, both Losartan and its active metabolites are not significantly accumulated in plasma.

    Both secretion in bile and kidneys contribute to the elimination of Losartan and its metabolites. After using the losartan oral dose of 14C markers in humans, about 35% of radioactive activity is intact in the urine and 58% in feces.

    hydrochlorothiazide

    Hydrochlorothiazide is not metabolized but quickly excreted in the kidneys. When the plasma level lasts for a minimum of 24 hours, the semi -cancellation time in plasma has been observed in the range of 5.6 - 14.8 hours. At least 61% of oral doses are eliminated in the form of unchanged within 24 hours.

    characteristics in patients

    losartan - hydrochlorothiazide

    Losartan's plasma concentrations and active metabolites, as well as the absorption of hydrochlorothiazide in older high blood pressure patients are not significant than young patients.

    losartan

    After oral use in patients with mild and medium alcoholic cirrhosis, Losartan's plasma concentrations and its active metabolites are 5 times higher (Losartan) and 1.7 times (active metabolites) compared to young healthy volunteers.

    Both Losartan and its active metabolites cannot be removed by hemolysis.

    How to use

    Take oral use.

    Can take Hyzaar® with other hypertension medications.

    Can drink Hyzaar® with or not food.

    Dosage

    High blood pressure

    Starting and maintaining dose is usually taken once a day, each time a Hyzaar® 50/12.5 tablet (Losartan 50mg/Hydrochlorothiazide 12.5mg). For patients who do not respond sufficiently with Hyzaar® 50/12.5, can increase the dose at each time a Hyzaar® 100/25 (Fortzaar) (Losartan 100mg/Hydrochlorothiazide 25mg) once a day, or drink once a day, each time Hyzaar 50/12.5.

    The maximum dose is once a day, 1 tablet of Hyzaar 100/25 (Fortzaar), or drink once a day, 2 Hyzaar® 50/12.5 tablets. In general, the effect of treating high blood pressure is achieved within the first three weeks of treatment. Hyzaar should not be used for patients who lose the volume of circulatory fluid (for example, high -dose dosage treatmenters).

    Hyzaar® is not recommended for patients with severe renal impairment (Creatinine clearance ≤ 30ml/min) or patients with liver failure.

    No need to adjust the starting dose of Hyzaar® 50/12.5 for elderly patients. Do not use Hyzaar® 100/25 (Fortzaar) is the starting dose for this patient group.

    Reducing the risk of cardiovascular disease and cardiovascular death in patients with hypertension with left ventricular hypertrophy

    Normal starting dose is 50mg of Losartan, drink once a day. If the target blood pressure is not reached with the dose of Losartan 50mg, the dose can be adjusted by using Losartan combination with low -dose hydrochlorothiazide (12.5mg) and if necessary, the dose may increase to Losartan level 100mg/hydrochlorothiazide 12.5mg (Hyzaar Plus), once daily taken. Hyzaar® 50/12.5 and Hyzaar 100/25 (Fortzaar) are the appropriate formulas in patients who need to use Losartan in combination with Hydrochlorothiazide.

    Children

    Elderly

    In clinical studies, there is no significant difference in the effectiveness and safety of Hyzaar® between the elderly (≥ 65 years old) and the younger (

    Note: The above dose is for reference only. Specific dosage depends on the condition and level of progression of the disease. For a suitable dose, you need to consult a doctor or medical specialist.What do

    do when overdose? Treatment is symptomatic and supportive. Need to stop Hyzaar® and carefully monitor patients. The proposed measures are vomiting if they have just taken Hyzaar®, rehydration, electrolyte balance, liver coma treatment, handling of blood pressure loss according to normal processes.

    losartan

    Data on people overdose is limited. The most common manifestation of overdose is hypotension and tachycardia; Sometimes the heart is slow due to stimulation of the sympathetic cord (vagus nerve). When hypotension of symptoms occurs, it is necessary to have supportive treatment.

    cannot remove Losartan and the active metabolites of this drug with dialysis.

    hydrochlorothiazide

    The most common signs and symptoms of this diuretic overdose are the decrease in electrolytes (hypokalemia, blood chlorine, blood sodium huh) and dehydration due to strong diuretic benefits. If combined with digitalis, the reduction of blood potassium can make the arrhythmia worse.

    Not yet determined the degree of removal of hydrochlorothiazide by dialysis.

    In an emergency, call the 115 emergency center immediately or go to the nearest local health station.

    What to do when you forget a dose? However, if close to the next dose, skip the forgotten dose and take the next dose at the time as planned. Note that it should not be used double the prescribed dose.

    Side Effects

    When using Hyzaar®, you may experience unwanted effects (ADR).

    In clinical trials with Losartan Kali - Hydrochlorothiazid, there are no specific harmful reactions for this combination. The harmful reaction is limited only to the reactions that have been encountered for Losartan, and/or for hydrochlorothiazide. Hyzaar's general reaction ratio is equivalent to the placebo group.

    In general, Hyzaar® is well tolerated. Most of the harmful reactions are mild and transient, and no need to stop the drug.

    In clinical trials on radical hypertension, dizziness is the only adverse effect that occurs at a higher rate in the placebo group, about 1% or a little bit in Hyzaar® users. In a controlled clinical study in people with high blood pressure with left ventricular hypertrophy, often coordinated with losartan with hydrochlorothiazide, generally tolerated. The most common side effects related to drugs are dizziness, weakness/fatigue and dizziness.

    After bringing Hyzaar® to the market, there are also the following adverse effects:

  • Hematological disorders and lymphatic systems: thrombocytopenia, anemia, anemia, hemolytic anemia, leukemia, granulocytosis. Some of these patients have previously sufferedemia with other drugs with ACE inhibitors.
  • Eye disorders: Demonstrate yellow, fade away. and pulmonary edema). Schoenlein), necrotic toxicity of epidermis, urticaria, red skin, sensitive to light, lupus erythematosus. positive, impotence.

    When experiencing side effects of the drug, it is necessary to stop using and notify the doctor or go to the nearest medical facility for timely treatment.

    Contraindicated

    Hyzaar® drug contraindicated in the following cases:

  • Hypersensitivity to any component of this product.
  • Animal.
  • Hypersensitivity to other derivatives of the sulfonamide group.

  • Hyzaar® is not used with Aliskiren in diabetes patients.
  • Caution when using

    Losartan - Hydrochlorothiazide

    Toxicity for pregnancy

    The use of drugs on the Renin - Angiotensin system in the middle and the last three months of pregnancy reduces the kidney function of the fetus, increases disease and death in the fetus and babies. The result of amniotic fluid may be associated with lung reduction and skeletal deformation in fetus. The possible side effects in newborns include reducing skull production, anuria, hypotension, renal failure and death. When detecting pregnancy, Hyzaar must be stopped as soon as possible.

    Hypersensitivity

    Thich vascular.

    Liver failure, kidney failure

    Do not use Hyzaar in people with liver failure or severe kidney failure.

    losartan

    Renal function impairment

    In sensitive people, there is a report on renal function changes, including renal failure, as a result of the inhibition of the Renin - Angiotensin system; If the drug is stopped, these changes can recover.

    Other drugs that affect the Renin - Angiotensin system may increase urea - blood and creatinine - serum in the narrowing of the kidney artery on both sides or narrow the kidney artery in patients with a single kidney. These effects also meet with Losartan; If the drug is stopped, these kidney function changes can also recover.

    hydrochlorothiazide

    Hypotension and imbalance of fluid/electrolytes

    As for all medications for hypertension, symptomic hypotension may be experienced in some patients. It is necessary to observe in patients with clinical signs of fluid imbalance or electrolytes such as reducing volume, hypoglycet hypoglycet, alkaline chlorine, reducing blood magnesium or hypokalemia may occur during diarrhea or vomiting occurs. Need an electrolyte test in regular serum with time gap suitable for these patients.

    Effects on metabolism and endocrine

    Using Thiazide can reduce glucose tolerance. Can adjust the dosage of diabetes to treat diabetes, including insulin.

    Thiazide can reduce calcium secretion through urine and cause mild and interrupted serum calcium. Calcium - obvious blood can be a result of an increase in the hidden parathyroid gland. Need to stop using thiazid before conducting tests on parathyroid function.

    Use diuretic gums may increase cholesterol and triglycerides.

    Thiazid may increase blood uric acid and/or cause gout in some people. Because Losartan reduces blood uric acid, Losartan coordinates with hydrochlorothiazide will reduce the increase in uric acid caused by this diuretic.

    Other caution

    In Thiazid users, there are hypersensitivity reactions whether or not there is no history of allergies or bronchial asthma. There are dramatic or lupus erythematics after using thiazid

    The ability to drive and operate machinery

    so far, no information has shown that Hyzaar has influenced the ability to drive or operate the user's machines.

    Pregnancy

    Medicines directly acting on the Renin - Angiotensin system can cause damage and developing pregnancy. When detecting pregnancy, Hyzaar® must be stopped as soon as possible.

    Although there is no experience in using Hyzaar® in pregnant women, animal studies with Losartan Kali have shown that drugs that damage fetal and infant animals, sometimes die, the mechanism is considered through impact on the Renin - Angiotensin system. In humans, the excretion of the kidneys of pregnancy depends on the development of the Renin - Angiotensin system starting from the second quarter of pregnancy; Thus, the risk of pregnancy will increase if the mother uses Hyzaar® in the second and third quarter of pregnancy.

    The use of drugs on the Renin - Angiotensin system in the middle and the last three months of pregnancy reduces the kidney function of the fetus, increases disease and death in the fetus and babies. The result of amniotic fluid may be associated with lung reduction and skeletal deformation in fetus. The possible side effects in newborns include reducing skull production, anuria, hypotension, renal failure and death. When detecting pregnancy, Hyzaar® must be stopped as soon as possible.

    These harmful results are often associated with the use of these drugs in the middle and the last three months of pregnancy. Most epidemiological studies survey abnormalities in fetuses after exposure to anti -hypertension drugs used in the first three months of pregnancy, regardless of drugs that affect the Renin - Angiotensin system with other anti -hypertension drugs.

    The appropriate treatment of hypertension in the mother during pregnancy is important to optimize the results for both mother and pregnancy. In special cases when there is no such an appropriate replacement treatment for medication, which affects the Renin - Angiotensin system for a separate patient, must notify the mother about the risk that may occur for the fetus.

    It is necessary to conduct a mass ultrasound test to assess the environment in the amniotic fluid. Stop using Hyzaar if observing the lack of amniotic fluid unless this drug is considered a medicine to save life for the mother. Pregnancy tests may be appropriate, based on the week of gestational age. However, doctors and patients should know that the lack of amniotic fluid may not show until the pregnancy has been damaged for a long time. Needs to closely monitor babies with a history of Hyzaar exposure in the uterus on manifestations of hypotension, urinary discharge and hyperkalemia.

    Thiazid passes through the placenta and appears in the umbilical cord blood. It is not recommended to use the diuretics for healthy pregnant people and this can bring both mother and pregnancy to unnecessary risks, such as jaundice of fetus and newborn, thrombocytopenia and maybe other harmful reactions that have been encountered in adults, which are not preventing the development of pregnancy toxicity and there is no reliable evidence that the diuretic is useful to treat fetal infections.

    The period of breastfeeding

    It is unclear whether Losartan will excrete through breast milk or not. Thiazid passes through breast milk. Because of the harmful effect of breastfeeding, it is necessary to decide or stop breastfeeding or stopping the drug, depending on the importance of using the drug with the mother.

    Drug interaction

    losartan

    In clinical pharmacokinetics tests, any clinical interactions have not been determined with hydrochlorothiazid, digoxin, warfarin, cimetidine, phenobarbital (please read the hydrochlorothiazid section: Alcohol, Barbiturates or addictive drugs in the lower part), Ketoconazole and erythromycin. There have been reports on reducing the level of metabolic substances that are active of rifampin and fluconazole. The clinical value of these interactions has not been fully evaluated.

    As with other drugs belonging to the Angiotensin II receptor inhibitor group or have the same effect, when used with potassium -keeping (such as Spironolacton, Triamteren, Amiloride), Potassium Supplements, Salt Supplies containing potassium, can lead to increased potassium - serum.

    As well as other drugs that affect the excretion of sodium, can also reduce the lithium secretion. Therefore, if lithium salt is used with Angiotensin II receptor inhibitors, the amount of lithium must be monitored in serum.

    Non -steroid anti -inflammatory drugs (NSAIDs), including cycloxygenase -2 inhibitors (2 (COX inhibitors - 2), can reduce the effects of diuretic and other high blood pressure medications. Therefore, the lowering effect of the Angiotensin II receptor inhibitors may be impaired by NSAIDs, including the selective inhibitors of COX - 2.

    In some patients with renal dysfunction, it has been treated with nonsteroidal anti -inflammatory drugs including cyclooxygenase - 2 inhibitors, simultaneous use of Angiotensin II receptor inhibitors can lead to further impairment of kidney function. These effects can usually be recovered when stopping the drug.

    Dual inhibition of the Renin - Angiotensin - Aldosterone (RAAS) system by combining Angiotensin receptor inhibitors, ACE or Aliskiren inhibitors, which comes with an increased risk of hypotension, fainting, hyperkalemia, and changing renal function (including acute renal impairment) compared to the use of a single therapy. Strictly monitor blood pressure, kidney function and electrolyte on patients using Hyzaar and other drugs that affect RAAS. Do not use Aliskiren simultaneously with Hyzaar on diabetes patients. Avoid using Aliskiren with Hyzaar in patients with renal failure (GFR

    hydrochlorothiazide

    When coordinated, the following drugs may interact with the diuretics:

    alcohol, barbiturate or addictive drug

    Sacrifice the side effects of hypotension.

    Hemodias (insulin and oral medications)

    Need to adjust the dose of drugs to lower blood sugar.

    Other hypertension medications: Agreement effects.

    cholestyramine and Colestipol

    Reduce the absorption of hydrochlorothiazide when there is anion exchange plastic. The single dose of cholestyramine or Colestipol plastic combined with hydrochlorothiazide reduces the absorption of thiazid through the gastrointestinal tract in the order of 85% and 43%.

    corticosteroids, ACTH

    Increases power outages, especially hypokalemia.

    Amines as vascular (Adrenaline)

    may reduce the response to the amines as a circuit, but there is not enough basis to stop using.

    Non -reducing muscle relaxants (such as tuboCurarin)

    can increase response to muscle relaxants.

    lithium

    Digital diuretic reduces kidney clearance to lithium and creates a high risk of lithium toxicity, so it is not advisable to coordinate. Read the lithium manual carefully before using these preparations.

    Non -steroid anti -inflammatory drugs (NSAID) including cyclooxygenase inhibitors - 2

    In some people, using nonsteroidal anti -inflammatory drugs including cyclooxygenase inhibitors - 2 will reduce the effect of thiazid on diuretic benefits, sodium discharge and hypertension.

    Interaction with laboratory tests

    Due to the effect of calcium metabolism, thiazid may have interaction with tests on parathyroid function.

    Storage

    Store less than 30 ° C (86 ° F).
