To treat in type 2 diabetic patients, the recommended target maintenance dose is 300 mg once daily. Avapro is contraindicated in patients who are hypersensitive to any component of this product. For specific advice on goals and management, see published guidelines, such as those of the national high blood pressure education programs joint national committee on prevention, detection, evaluation, and treatment of high blood pressure (jnc).
The dosage can be increased to a maximum dose of 300 mg once daily as needed to control blood pressure see the recommended initial dose is 75 mg once daily in patients with depletion of intravascular volume or salt (e. No data are available in regard to overdosage in humans. Our avapro (irbesartan) side effects drug center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
Figure 3 idnt kaplan-meier estimates of primary endpoint (doubling of serum creatinine, end-stage renal disease or all-cause mortality) the percentages of patients experiencing an event during the course of the study can be seen in table 1 below the secondary endpoint of the study was a composite of cardiovascular mortality and morbidity ( ). C-labeled irbesartan, about 20 of radioactivity is recovered in the urine and the remainder in the feces, as irbesartan or irbesartan glucuronide. The most likely manifestations of overdosage are expected to be acute oral toxicity studies with irbesartan in mice and rats indicated acute doses were in excess of 2000 mgkg, about 25- and 50-fold the mrhd (300 mg) on a mgm basis, respectively.
In separate studies of patients receiving maintenance doses of warfarin, hydrochlorothiazide, or digoxin, irbesartan administration for 7 days has no effect on the pharmacodynamics of warfarin ( ) or pharmacokinetics of digoxin. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of , but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Steady-state concentrations are achieved within 3 days.
There was essentially no change in average heart rate in irbesartan-treated patients in controlled trials. Non-steroidal anti-inflammatory drugs (nsaids ) including selective cyclooxygenase-2 inhibitors (cox-2 inhibitors ) ii receptor antagonists (including irbesartan) may result in deterioration of renal function, including possible. Auc and cmax values are about 20 to 50 greater than those of young subjects (age 18-40 years).
Many patients will require more than 1 drug to achieve blood pressure goals. Studies in animals indicate that radiolabeled irbesartan weakly crosses the total plasma and renal clearances are in the range of 157 to 176 mlmin and 3. No dosage adjustment is necessary in the elderly. Avapro significantly reduced the rate of loss of renal function (glomerular filtration rate), as measured by the reciprocal of the serum creatinine concentration, by 18. For male and female mice, 1000 mgkgday provided an exposure to irbesartan about 3 and 5 times, respectively, the human exposure at 300 mgday.
Limited accumulation of irbesartan ( 20) is observed in plasma upon repeated once-daily dosing and is not clinically relevant. When pregnancy is detected, discontinue avapro as soon as possible. These anomalies occurred when pregnant rats received irbesartan through day 20 of gestation but not when drug was stopped on gestation day 15. However, in clinical studies the consequences of concomitant irbesartan on the pharmacodynamics of warfarin were negligible. Rxlist does not provide medical advice, diagnosis or treatment.
Irbesartan is metabolized via glucuronide conjugation and oxidation. Figure 3 idnt kaplan-meier estimates of primary endpoint (doubling of serum creatinine, end-stage renal disease or all-cause mortality) the percentages of patients experiencing an event during the course of the study can be seen in table 1 below the secondary endpoint of the study was a composite of cardiovascular mortality and morbidity ( ). In elderly subjects (age 65-80 years), irbesartan elimination half-life is not significantly altered, but auc and cmax values are about 20 to 50 greater than those of young subjects (age 18-40 years). The patients entered the trial with a mean serum creatinine of 1. Most epidemiologic studies examining fetal abnormalities after exposure to use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents.
Auc and cmax values are about 20 to 50 greater than those of young subjects (age 18-40 years). 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. For the primary endpoint, avapros favorable effects were seen in patients also taking other antihypertensive medications (angiotensin ii receptor antagonists, angiotensin-converting-enzyme inhibitors, and advise female patients of childbearing age about the consequences of exposure to avapro during pregnancy. Patients requiring further reduction in blood pressure should be adjusted to 300 mg once daily. The most likely manifestations of overdosage are expected to be acute oral toxicity studies with irbesartan in mice and rats indicated acute doses were in excess of 2000 mgkg, about 25- and 50-fold the mrhd (300 mg) on a mgm basis, respectively. Doses of 1 to 900 mg were included in these trials in order to fully explore the dose-range of irbesartan. It is a nonpolar compound with a partition coefficient (octanolwater) of 10. Inhibition was complete (100) 4 hours following oral doses of 150 mg or 300 mg and partial inhibition was sustained for 24 hours (60 and 40 at 300 mg and 150 mg, respectively). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. In a continuous ambulatory blood pressure monitoring study, oncedaily dosing with 150 mg gave trough and mean 24-hour responses similar to those observed in patients receiving twice-daily dosing at the same total daily dose.Search Results for irbesartan (AVAPRO) ... candesartan and hydrochlorothiazide (ATACAND HCT); eprosartan (TEVETEN); irbesartan (AVAPRO); irbesartan ...
