Use caution in treating patients whose renal function may depend on the renin-angiotension-aldosterone system eg, patients with severe CHF. Compared to normal subjects, the total plasma clearance of losartan in patients with hepatic insufficiency was about 50% lower, and the oral bioavailability was about doubled. The lower starting dose of losartan recommended for use in patients with hepatic impairment cannot be given using Losartan Potassium and Hydrochlorothiazide. Hydrochlorothiazide USP is a white or practically white, practically odorless, crystalline powder with a molecular weight of 297. loratadine
Coadministration of losartan with other drugs that raise serum potassium levels may result in hyperkalemia. Monitor serum potassium in such patients. LVH can happen from several things. High blood pressure is the most common cause of LVH. Hydrochlorothiazide decreases urinary calcium excretion and may cause elevations of serum calcium. Monitor calcium levels.
In patients who are hypersensitive to any component of this product. Blood pressure reduction measured at trough was similar for both treatment groups but blood pressure was not measured at any other time of the day. At the end of study or at the last visit before a primary endpoint, the mean blood pressures were 144. Long arms, legs, fingers, and toes and flexible joints. CYP2C9 Substrates: CYP2C9 Inhibitors Moderate may decrease the metabolism of CYP2C9 Substrates. Lifestyle changes such as stress reduction programs, exercise, and dietary changes may increase the effectiveness of this medicine. Talk to your doctor or pharmacist about lifestyle changes that might benefit you.
No carcinogenicity studies have been conducted with the losartan potassium-hydrochlorothiazide combination. The pharmacodynamic consequences of concomitant use of losartan and inhibitors of P450 2C9 have not been examined. Subjects who do not metabolize losartan to active metabolite have been shown to have a specific, rare defect in cytochrome P450 2C9. These data suggest that the conversion of losartan to its active metabolite is mediated primarily by P450 2C9 and not P450 3A4. There are no dosage adjustments provided in the manufacturer's labeling. In most cases, Marfan syndrome is inherited from a parent, but 1 in 4 cases occurs in people with no known family history of the disease. It occurs equally in men and women, who have a 50% risk of passing on the gene to their children. Marfan syndrome is present at birth, but may not be diagnosed until adolescence or later. Everyone with Marfan syndrome has the same defective gene, but not everyone experiences the same symptoms to the same degree.
Biliary excretion contributes to the elimination of losartan and metabolite. About 4% is excreted unchanged in the urine and 6% excreted as active metabolite in urine. American Heart Association with specific antibiotic guidelines. Caution patient that inadequate fluid intake, excessive perspiration, diarrhea, or vomiting can lead to excessive fall in BP resulting in light-headedness or fainting. Plasma protein binding is constant over the concentration range achieved with recommended doses. Studies in rats indicate that losartan crosses the blood-brain barrier poorly, if at all. Losartan Potassium and Hydrochlorothiazide tablets contain 2 prescription medicines, an angiotensin receptor blocker ARB and a diuretic water pill. Medications are typically not used to treat Marfan syndrome. However, your doctor may prescribe a beta-blocker, which decreases the forcefulness of the heartbeat and the pressure within the arteries, thus preventing or slowing the enlargement of the aorta. Beta-blocker therapy is usually started when the person with Marfan syndrome is young. Metabolism: Losartan is an orally active agent that undergoes substantial first-pass metabolism by cytochrome P450 enzymes. It is converted, in part, to an active carboxylic acid metabolite that is responsible for most of the angiotensin II receptor antagonism that follows losartan treatment. About 14% of an orally-administered dose of losartan is converted to the active metabolite. In addition to the active carboxylic acid metabolite, several inactive metabolites are formed. In vitro studies indicate that cytochrome P450 2C9 and 3A4 are involved in the biotransformation of losartan to its metabolites. Emphasize importance of other modalities of BP control: moderate intake of alcohol and salt, regular exercise, smoking cessation, and weight control. Hypotension: Symptomatic hypotension may occur upon initiation in patients who are salt or volume depleted eg, those treated with high-dose diuretics; correct volume depletion prior to administration. This transient hypotensive response is not a contraindication to further treatment with losartan.
Genetic counseling should be performed prior to pregnancy because Marfan syndrome is an inherited condition. Pregnant women with Marfan syndrome are also considered high-risk cases. If the aorta is normal size, the risk for dissection is lower, but not absent. Those with even slight enlargement are at higher risk and the stress of pregnancy may cause more rapid dilation. Careful follow-up, with frequent blood pressure checks and monthly echocardiograms is required during pregnancy. If there is rapid enlargement or aortic regurgitation, may be required. Your doctor will discuss with you the best method of delivery with you. Minor increases in BUN or serum creatinine, small decreases in Hgb and Hct, occasional elevations in liver enzymes and serum bilirubin postmarketing.

If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. betapace
Genetic testing alone cannot tell you if you have Marfan syndrome, as there are other connective tissue disorders. The antihypertensive effect of angiotensin II receptor antagonists, including losartan, may be attenuated by NSAIDs, including selective COX-2 inhibitors. High Blood Pressure hypertension. Blood pressure is the force in your blood vessels when your heart beats and when your heart rests. You have high blood pressure when the force is too much. The losartan ingredient in Losartan Potassium and Hydrochlorothiazide tablets can help your blood vessels relax so your blood pressure is lower. The hydrochlorothiazide ingredient in Losartan Potassium and Hydrochlorothiazide tablets work by making your kidneys pass more water and salt. These considerations may guide selection of therapy. HER2 in order to develop more targeted treatments for women whose breast cancers are not HER2-positive and therefore do not respond to Herecptin. Pholcodine: Blood Pressure Lowering Agents may enhance the hypotensive effect of Pholcodine. Losartan Potassium and Hydrochlorothiazide tablets are indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure lowers the risk of fatal and non-fatal cardiovascular CV events, primarily strokes and myocardial infarction. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including losartan and hydrochlorothiazide. alfo.info bimatoprost
This information is generalized and not intended as specific medical advice. Losartan Potassium and Hydrochlorothiazide tablets. See a complete list of ingredients in Losartan Potassium and Hydrochlorothiazide tablets at the end of this leaflet. Hydrochlorothiazide, a sulfonamide, can cause an idiosyncratic reaction, resulting in acute transient myopia and acute angle-closure glaucoma. Symptoms include acute onset of decreased visual acuity or ocular pain and typically occur within hours to weeks of drug initiation. Untreated acute angle-closure glaucoma can lead to permanent vision loss. The primary treatment is to discontinue hydrochlorothiazide as rapidly as possible. Prompt medical or surgical treatments may need to be considered if the intraocular pressure remains uncontrolled. Risk factors for developing acute angle-closure glaucoma may include a history of sulfonamide or penicillin allergy. Plasma losartan concentrations are twice as high in hypertensive women as hypertensive men, but plasma concentrations of active metabolite are similar. No dosage adjustment is necessary. Talk to your doctor about other ways to lower your blood pressure if you plan to become pregnant. Aurobindo Pharma USA, Inc. Marfan syndrome can rupture the inner layers of the aorta, causing dissection that leads to bleeding in the wall of the vessel. Aortic dissection can be deadly. Surgery may be required to replace the affected part of the aorta. Medicines are sometimes prescribed for conditions that are not mentioned in patient information leaflets. Do not use Losartan Potassium and Hydrochlorothiazide tablets for a condition for which it was not prescribed. Do not give Losartan Potassium and Hydrochlorothiazide tablets to other people, even if they have the same symptoms that you have. CYP3A4 Inducers Moderate: May decrease the serum concentration of CYP3A4 Substrates. LIFE study patients there were 29 primary endpoints among 263 patients on atenolol 11%, 26 per 1000 patient-years and 46 primary endpoints among 270 patients 17%, 42 per 1000 patient-years on losartan. This finding could not be explained on the basis of differences in the populations other than race or on any imbalances between treatment groups. In addition, blood pressure reductions in both treatment groups were consistent between Black and non-Black patients. Given the difficulty in interpreting subset differences in large trials, it cannot be known whether the observed difference is the result of chance. MiFEPRIStone: May increase the serum concentration of CYP2C9 Substrates. Management: Use CYP2C9 substrates at the lowest recommended dose, and monitor closely for adverse effects, during and in the 2 weeks following mifepristone treatment. cost of antivert at superdrug
Psychiatric disorders: Insomnia, restlessness. As a selective and competitive, nonpeptide angiotensin II receptor antagonist, losartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II; losartan interacts reversibly at the AT1 and AT2 receptors of many tissues and has slow dissociation kinetics; its affinity for the AT1 receptor is 1000 times greater than the AT2 receptor. Angiotensin II receptor antagonists may induce a more complete inhibition of the renin-angiotensin system than ACE inhibitors, they do not affect the response to bradykinin, and are less likely to be associated with nonrenin-angiotensin effects eg, cough and angioedema. Losartan increases urinary flow rate and in addition to being natriuretic and kaliuretic, increases excretion of chloride, magnesium, uric acid, calcium, and phosphate. Sarilumab: May decrease the serum concentration of CYP3A4 Substrates. Concomitant use of potassium-sparing diuretics, potassium supplements, or salt substitutes containing potassium may lead to increases in serum potassium.

Molsidomine: May enhance the hypotensive effect of Blood Pressure Lowering Agents. Hypoglycemia 14%; hyperkalemia 7%; weight gain 4%; hyponatremia postmarketing. The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables. Initiation of Losartan Potassium and Hydrochlorothiazide is not recommended for patients with hepatic impairment because the appropriate starting dose of losartan, 25 mg, is not available. Tell your doctor if your condition does not improve or if it worsens for example, your blood pressure readings increase. Cataract 7%; nasal congestion 2%. Symptomatic hypotension may occur after initiation of losartan in patients who are volume depleted eg, those treated with diuretics. Correct these conditions prior to administration of losartan or use a lower starting dose. Cases of cough, including positive re-challenges, have been reported with the use of losartan in postmarketing experience. The University of Michigan has filed a patent on AGTR1 and is seeking commercial partners.
Canadian labeling: Use is not recommended. It is not known whether losartan is excreted in human milk, but significant levels of losartan and its active metabolite were shown to be present in rat milk. Thiazides appear in human milk.

Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly discard this product when it is expired or no longer needed. Consult your pharmacist or local waste disposal company. In patients who are elderly, volume-depleted including those on diuretic therapy or with compromised renal function, coadministration of NSAIDs, including selective COX-2 inhibitors, with angiotensin II receptor antagonists including losartan may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving losartan and NSAID therapy. The terminal half-life of losartan is about 2 hours and of the metabolite is about 6 to 9 hours. After single doses of losartan administered orally, about 4% of the dose is excreted unchanged in the urine and about 6% is excreted in urine as active metabolite. Biliary excretion contributes to the elimination of losartan and its metabolites. Following oral 14C-labeled losartan, about 35% of radioactivity is recovered in the urine and about 60% in the feces. Following an intravenous dose of 14C-labeled losartan, about 45% of radioactivity is recovered in the urine and 50% in the feces. Neither losartan nor its metabolite accumulate in plasma upon repeated once-daily dosing. cost redustat kit

Low blood pressure may cause you to feel faint or dizzy. Lie down if you feel faint or dizzy. Call your doctor right away. Marfan syndrome is caused by a change in the gene that controls how the body makes fibrillin, an essential component of connective tissue that contributes to its strength and elasticity. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death. When pregnancy is detected, discontinue Losartan Potassium and Hydrochlorothiazide as soon as possible. The following adverse reactions have been identified during post-approval use of Losartan Potassium and Hydrochlorothiazide. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure. Do not share this medication with others. What should I tell my doctor before taking Losartan Potassium and Hydrochlorothiazide tablets? Prostacyclin Analogues: May enhance the hypotensive effect of Blood Pressure Lowering Agents. Continued How Is Marfan Syndrome Diagnosed?

Reduction in the Risk of Stroke: The LIFE study was a multinational, double-blind study comparing losartan and atenolol in 9193 hypertensive patients with ECG-documented left ventricular hypertrophy. Patients with myocardial infarction or stroke within six months prior to randomization were excluded. Although losartan may be used to prevent kidney problems or treat people who have kidney problems, it may also rarely cause serious kidney problems or make them worse. Your doctor will check your kidney function while you are taking losartan. Tell your doctor right away if you have any signs of kidney problems such as a change in the amount of urine.
Black patients had a larger response to hydrochlorothiazide than non-Black patients and a smaller response to losartan. The overall response to the combination was similar for Black and non-Black patients. Drugs that act on the renin-angiotensin system can cause injury and death to the developing fetus. Discontinue as soon as possible once pregnancy is detected. The use of drugs which act on the renin-angiotensin system are associated with oligohydramnios. Oligohydramnios, due to decreased fetal renal function, may lead to fetal lung hypoplasia and skeletal malformations. It also stimulates aldosterone secretion by the adrenal cortex.
