Valutazione 4.5 sulla base di 113 voti.

Living females had a rebuff increase in early resorptions and a corresponding decrement in survive fetuses Vendita However, nevertheless. Every endeavor has been made to ensure that the info provided by on this page is accurate, Vendita, however, peculiarly hypokalemia. Steady-state Avalide are achieved inside 3 years.

These effects are usually reversible. Therefore, monitor renal function and blood pressure periodically in patients receiving irbesartan and NSAID therapy. Therefore, when Avalide irbesartan-hydrochlorothiazide tablets and non-steroidal anti-inflammatory agents are used concomitantly, the patient should be observed closely to determine if the desired effect of the diuretic is obtained.

Dual Blockade of the Renin-Angiotensin System RAS Dual blockade of the RAS with angiotensin-receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and changes in renal function including acute renal failure compared to monotherapy. Closely monitor blood pressure, renal function, and electrolytes in patients on Avalide and other agents that affect the RAS.

In most patients no benefit has been associated with using two RAS inhibitors Avalide. In general, avoid combined use of RAS inhibitors. Cholestyramine and Colestipol Resins Absorption of hydrochlorothiazide is impaired in the presence of anionic exchange resins. Monitor lithium levels in patients receiving Avalide and lithium. Carbamazepine Concomitant use Vendita carbamazepine and hydrochlorothiazide has been associated with the risk of symptomatic hyponatremia.

Monitor electrolytes during concomitant use. 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 Avalide as soon as possible. Appropriate Avalide of maternal hypertension during pregnancy is important to optimize outcomes for both mother and fetus.

Perform serial ultrasound examinations to assess the intra-amniotic environment, Avalide In Vendita. If oligohydramnios is observed, discontinue Avalide, unless it is considered lifesaving for the mother. Fetal testing may be appropriate, based on the week of pregnancy. Patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. Closely observe infants with histories of in utero exposure to Avalide for hypotension, oliguria, and hyperkalemia [See Use in Specific Populations 8.

Irbesartan crosses the placenta in rats and rabbits, Avalide In Vendita.

Important information

Subcutaneous edema also occurred in fetuses at doses about 4 times the MRHD based on body surface area, Avalide In Vendita. Pregnant rabbits given oral doses of irbesartan equivalent to 1. Surviving females had a slight increase in early resorptions and a corresponding decrease in live fetuses Avalide Nonclinical Toxicology 13. Radioactivity was present in the rat and rabbit fetus during late gestation and in rat milk following oral doses of radiolabeled irbesartan. Nursing Mothers It is not known whether irbesartan is excreted in human milk, but irbesartan or some metabolite of irbesartan is secreted at low concentration in the milk of lactating rats.

Thiazides appear in human milk. Pediatric Use Neonates with a History of in Vendita Exposure to Avalide If oliguria or hypotension occurs, direct attention toward support of blood pressure Avalide renal perfusion. Safety and effectiveness in pediatric patients have not been established. Geriatric Use Of 1694 patients receiving Avalide in controlled clinical studies of hypertension, 264 15. However, daily doses of 900 mg for 8 weeks were well tolerated. The most likely manifestations of overdosage are expected to be hypotension and tachycardia; bradycardia might also occur from overdose.

Irbesartan is not removed by hemodialysis. To obtain up-to-date information about the treatment of overdosage, a good resource is a Vendita regional Poison Control Center.

Hydrochlorothiazide The most common signs and symptoms Vendita overdose observed in humans are those caused by electrolyte depletion hypokalemia, hypochloremia, hyponatremia and dehydration resulting from excessive diuresis. The degree to which hydrochlorothiazide is removed by hemodialysis has not been established. Avalide Description Avalide irbesartan-hydrochlorothiazide tablets are a combination of an angiotensin II receptor antagonist AT1 subtype, irbesartan, and a thiazide diuretic, Avalide HCTZ.

Irbesartan is a non-peptide compound, chemically described as a 2-butyl-3- -1,3-diazaspiro[4. Irbesartan is a white to off-white crystalline powder with a molecular weight of 428.

Irbesartan is slightly soluble in alcohol and methylene chloride and practically insoluble in water. Hydrochlorothiazide is 6-chloro-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. Hydrochlorothiazide is a white, or practically white, crystalline powder with a molecular weight of 297. Hydrochlorothiazide is slightly soluble in water and freely soluble in sodium hydroxide solution.

All dosage strengths contain the following inactive ingredients: Angiotensin II is the principal pressor agent of the RAS and also stimulates aldosterone synthesis and secretion by adrenal cortex, cardiac contraction, renal resorption of sodium, activity of the sympathetic nervous system, and smooth muscle cell growth. Irbesartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively binding to the AT1 angiotensin II receptor. Irbesartan is a specific competitive antagonist of AT1 receptors with a much greater affinity more than 8500-fold for the AT1 receptor than for the AT2 receptor, and no agonist activity.

Blockade of the AT1 receptor removes the negative feedback of angiotensin II on renin secretion, but the resulting increased plasma renin activity and circulating angiotensin II do not overcome the effects of irbesartan on blood pressure. Because irbesartan does not inhibit ACE, it does not affect the response to bradykinin; whether this has clinical relevance is not known.

Hydrochlorothiazide Hydrochlorothiazide is a thiazide diuretic. Thiazides affect the renal tubular mechanisms of electrolyte reabsorption, directly increasing excretion of sodium and chloride in approximately equivalent amounts. The mechanism of the antihypertensive effect of thiazides is not fully understood. Pharmacodynamics Irbesartan In healthy subjects, single oral irbesartan doses of up to 300 mg produced dose-dependent inhibition of the pressor effect of Avalide II infusions.

In multiple dose studies in hypertensive patients, there were no clinically important effects on fasting triglycerides, total cholesterol, HDL-cholesterol, or fasting glucose concentrations. Potentiation of orthostatic hypotension may Avalide. Possible increased responsiveness to muscle relaxants such as curare derivatives.

Corticosteroids, ACTH—intensified electrolyte depletion, particularly hypokalemia. Pharmacokinetics Irbesartan Irbesartan is an orally active agent that does not require biotransformation into an active form, Avalide In Vendita. Food does not affect the bioavailability of irbesartan. Irbesartan exhibits linear pharmacokinetics over the therapeutic dose range. The terminal elimination half-life of irbesartan averaged 11 to 15 hours.

Steady-state concentrations are achieved within 3 days. Hydrochlorothiazide When plasma levels have been followed for at least 24 hours, the plasma half-life has been observed to vary between 5. Metabolism and Elimination Irbesartan Irbesartan is metabolized Avalide glucuronide conjugation and oxidation. The remaining oxidative metabolites do not add appreciably to irbesartan’s pharmacologic activity.

Irbesartan and its metabolites are excreted by both biliary and renal Vendita. In vitro studies of irbesartan oxidation by cytochrome P450 isoenzymes indicated irbesartan was oxidized primarily by 2C9; metabolism by 3A4 was negligible. There was no induction or inhibition of 3A4. Hydrochlorothiazide Hydrochlorothiazide is not metabolized but is eliminated rapidly by the kidney.

The average volume of distribution is 53 to 93 liters. With repetitive dosing, irbesartan accumulates to no clinically relevant extent. Studies in animals indicate that radiolabeled irbesartan weakly crosses the blood-brain barrier and placenta. Irbesartan is excreted in the milk of lactating rats. Hydrochlorothiazide Hydrochlorothiazide crosses the placental but not the blood-brain barrier and is excreted in breast milk.

Gender No gender-related differences in pharmacokinetics were observed in healthy elderly age 65 to 80 years or in healthy young age 18 to 40 years subjects. No gender-related dosage adjustment is necessary. No dosage adjustment is necessary in the elderly. Renal insufficiency The pharmacokinetics of irbesartan were not altered in patients with renal impairment or in patients on hemodialysis.

No dosage adjustment is necessary in patients with mild to severe renal impairment unless a patient with renal impairment is Vendita volume depleted. No dosage adjustment is necessary in patients with hepatic insufficiency, Avalide In Vendita. However, in clinical studies the consequences of concomitant irbesartan on the pharmacodynamics of warfarin were negligible. Concomitant nifedipine or hydrochlorothiazide had no effect on irbesartan pharmacokinetics. Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment of Fertility Irbesartan-Hydrochlorothiazide No Vendita studies have been conducted with the irbesartan-hydrochlorothiazide combination.

Irbesartan-hydrochlorothiazide was not mutagenic in standard in vitro tests Ames microbial test and Chinese hamster mammalian-cell forward gene-mutation assay, Avalide In Vendita.

Irbesartan-hydrochlorothiazide was negative in tests for induction of chromosomal Avalide in vitro—human lymphocyte assay; in vivo—mouse micronucleus study. The combination of irbesartan and hydrochlorothiazide has not been evaluated in definitive studies of fertility. Irbesartan was not mutagenic in a battery of in vitro tests Ames microbial test, rat hepatocyte DNA repair test, V79 mammalian-cell forward gene-mutation assay. Irbesartan was negative in several tests for induction of chromosomal aberrations in vitro—human lymphocyte assay; in Vendita micronucleus study. The NTP, however, found equivocal evidence for hepatocarcinogenicity in male mice.

Hydrochlorothiazide was not genotoxic in vitro in the Ames mutagenicity assay of Salmonella typhimurium strains TA 98, TA 100, Avalide In Vendita, TA 1535, TA 1537, and TA 1538 and in the Chinese Hamster Ovary CHO test for chromosomal aberrations, or in vivo in assays using mouse germinal cell chromosomes, Chinese hamster bone marrow chromosomes, and the Drosophila sex-linked recessive lethal trait gene.

Surviving females receiving this dose about 1.

Irbesartan was found to cross the placental barrier in rats and rabbits. Clinical Studies Irbesartan Monotherapy The antihypertensive effects of irbesartan were examined in 7 major placebo-controlled, 8 to 12-week trials in patients with baseline diastolic blood pressures of 95 to 110 mmHg. Doses of 1 to 900 mg were included in these trials in order to fully explore the dose-range of irbesartan. Two of the 7 placebo-controlled trials identified above and 2 additional placebo-controlled studies examined the antihypertensive effects of irbesartan and hydrochlorothiazide in combination, Avalide In Vendita.

The 7 studies of irbesartan monotherapy included a total of 1915 patients randomized to irbesartan 1 to 900 mg and 611 patients randomized to placebo. No further increase in Avalide was seen at dosages greater Vendita 300 mg. The dose-response relationships for effects on systolic and diastolic pressure are shown in Figures 3 and 4. This was seen with both once-daily and twice-daily dosing, Avalide In Vendita.
