Gastrointestinal disorders: Dyspepsia, abdominal pain, gastric irritation, cramping, diarrhea, constipation, nausea, vomiting, pancreatitis, sialoadenitis.
Absorption: Following oral administration, losartan is well absorbed and undergoes substantial first-pass metabolism. The systemic bioavailability of losartan is approximately 33%. Mean peak concentrations of losartan and its active metabolite are reached in 1 hour and in 3 to 4 hours, respectively. While maximum plasma concentrations of losartan and its active metabolite are approximately equal, the AUC area under the curve of the metabolite is about 4 times as great as that of losartan. These considerations may guide selection of therapy. Aurobindo Pharma USA, Inc. Nonsteroidal Anti-Inflammatory Agents. Specifically, the combination may result in a significant decrease in renal function. Nonsteroidal Anti-Inflammatory Agents may diminish the therapeutic effect of Angiotensin II Receptor Blockers. The combination of these two agents may also significantly decrease glomerular filtration and renal function.
This medication may increase your potassium levels. Before using potassium supplements or salt substitutes that contain potassium, consult your doctor or pharmacist. 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. 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. Because of the potential for adverse effects on the nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
What should I tell my doctor before taking Losartan Potassium and Hydrochlorothiazide tablets?

Caution patient that inadequate fluid intake, excessive perspiration, diarrhea, or vomiting can lead to excessive fall in BP resulting in light-headedness or fainting. What Is Losartan and How Does It Work? Losartan Potassium and Hydrochlorothiazide. Monitor renal function periodically in these patients. 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. CYP2C9 Inhibitors Moderate: May decrease the metabolism of CYP2C9 Substrates. Hyperuricemia may occur or frank gout may be precipitated in patients receiving thiazide therapy. Because losartan decreases uric acid, losartan in combination with hydrochlorothiazide attenuates the diuretic-induced hyperuricemia.

Allow concentrate to stand for 1 hour, then shake for 1 minute. Surgical patients: In patients on chronic angiotensin receptor blocker ARB therapy, intraoperative hypotension may occur with induction and maintenance of general anesthesia; however, discontinuation of therapy prior to surgery is controversial. If continued preoperatively, avoidance of hypotensive agents during surgery is prudent Hillis, 2011. CYP3A4 Inducers Strong: May increase the metabolism of CYP3A4 Substrates. Management: Consider an alternative for one of the interacting drugs. Some combinations may be specifically contraindicated. Consult appropriate manufacturer labeling. But if there were a study in which losartan were given only to women with breast cancers linked to overexpression of AGTR1, it would be much easier to detect an effect. Before such a trial can be set up, however, scientists must first develop a way to easily detect AGTR1 overexpression. Symptomatic Hypotension: Advise patients that lightheadedness can occur, especially during the first days of therapy, and to report this symptom to a healthcare provider. Inform patients that dehydration from inadequate fluid intake, excessive perspiration, vomiting, or diarrhea may lead to an excessive fall in blood pressure. 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. ursofalk
Once that test is available -- something that should take only a few months, says Rhodes -- a clinical trial should be easier than usual to set up because of the availability of an existing, approved therapy whose side effects are known.

AUCs for losartan and its active metabolite were approximately 66 and 26 times the exposure achieved in man at the maximum recommended human daily dosage 100 mg. 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. Genetic testing alone cannot tell you if you have Marfan syndrome, as there are other connective tissue disorders. 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. imen.info eldepryl

Emphasize importance of other modalities of BP control: moderate intake of alcohol and salt, regular exercise, smoking cessation, and weight control. Losartan plasma levels may be elevated, increasing the antihypertensive and adverse effects. 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.

Monitor for increased effects of tizanidine, including adverse reactions. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension for example, patients with diabetes or hyperlipidemia and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal.
