Discuss treatment options with women planning to become pregnant. Patients should be asked to report pregnancies to their physicians as soon as possible. These doses in mice and rats are about 2.

Mutagenicity assays did not reveal any valsartan-related effects at either the gene or chromosome level. These assays included bacterial mutagenicity tests with Salmonella Ames and E coli; a gene mutation test with Chinese hamster V79 cells; a cytogenetic test with Chinese hamster ovary cells; and a rat micronucleus test. Use In Specific Populations Pregnancy Pregnancy Category D 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.

Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death. When pregnancy is detected, discontinue Diovan as soon as possible. These adverse outcomes are usually associated with use of these drugs in the second and third trimesters of pregnancy. Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents.

Appropriate management of maternal hypertension during pregnancy is important to optimize outcomes for both mother and fetus. In the unusual case that there is no appropriate alternative to therapy with drugs affecting the reninangiotensin system for a particular patient, apprise the mother of the potential risk to the fetus. Perform serial ultrasound examinations to assess the intra-amniotic environment.

If oligohydramnios is observed, discontinue Diovan, 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 Diovan for hypotension, oliguria , and hyperkalemia [see Pediatric Use].

Nursing Mothers It is not known whether Diovan is excreted in human milk. Diovan was excreted in the milk of lactating rats; however, animal breast milk drug levels may not accurately reflect human breast milk levels. Because many drugs are excreted into human milk and because of the potential for adverse reactions in nursing infants from Diovan, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use The antihypertensive effects of Diovan have been evaluated in two randomized, double-blind clinical studies in pediatric patients from and years of age [see Clinical Studies ].

The pharmacokinetics of Diovan have been evaluated in pediatric patients 1 to 16 years of age [see Pharmacokinetics , Special Populations, Pediatric]. Diovan was generally well tolerated in children years and the adverse experience profile was similar to that described for adults.

In children and adolescents with hypertension where underlying renal abnormalities may be more common, renal function and serum potassium should be closely monitored as clinically indicated. These kidney effects in neonatal rats represent expected exaggerated pharmacological effects that are observed if rats are treated during the first 13 days of life.

Since this period coincides with up to 44 weeks after conception in humans, it is not considered to point toward an increased safety concern in 6 to 16 year old children.

Geriatric Use In the controlled clinical trials of valsartan, 1, No overall difference in the efficacy or safety of valsartan was observed in this patient population, but greater sensitivity of some older individuals cannot be ruled out. There were no notable differences in efficacy or safety between older and younger patients in either trial. Hepatic Impairment No dose adjustment is necessary for patients with mild-to-moderate liver disease. No dosing recommendations can be provided for patients with severe liver disease.

The most likely manifestations of overdosage would be hypotension and tachycardia ; bradycardia could occur from parasympathetic vagal stimulation. Depressed level of consciousness, circulatory collapse and shock have been reported. If symptomatic hypotension should occur, supportive treatment should be instituted.

Diovan valsartan is not removed from the plasma by hemodialysis. Angiotensin II is the principal pressor agent of the renin-angiotensin system, with effects that include vasoconstriction , stimulation of synthesis and release of aldosterone , cardiac stimulation, and renal reabsorption of sodium. Diovan valsartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland.

Its action is therefore independent of the pathways for angiotensin II synthesis. There is also an AT2 receptor found in many tissues, but AT2 is not known to be associated with cardiovascular homeostasis. Valsartan has much greater affinity about 20,fold for the AT1 receptor than for the AT2 receptor. The increased plasma levels of angiotensin II following AT1 receptor blockade with valsartan may stimulate the unblocked AT2 receptor.

The primary metabolite of valsartan is essentially inactive with an affinity for the AT1 receptor about oneth that of valsartan itself. Blockade of the renin-angiotensin system with ACE inhibitors , which inhibit the biosynthesis of angiotensin II from angiotensin I, is widely used in the treatment of hypertension. Whether this difference has clinical relevance is not yet known. Valsartan does not bind to or block other hormone receptors or ion channels known to be important in cardiovascular regulation.

Blockade of the angiotensin II receptor inhibits the negative regulatory feedback of angiotensin II on renin secretion, but the resulting increased plasma renin activity and angiotensin II circulating levels do not overcome the effect of valsartan on blood pressure. Pharmacodynamics Valsartan inhibits the pressor effect of angiotensin II infusions.

No information on the effect of larger doses is available. Removal of the negative feedback of angiotensin II causes a 2- to 3-fold rise in plasma renin and consequent rise in angiotensin II plasma concentration in hypertensive patients.

Minimal decreases in plasma aldosterone were observed after administration of valsartan; very little effect on serum potassium was observed. In multiple-dose studies in hypertensive patients with stable renal insufficiency and patients with renovascular hypertension, valsartan had no clinically significant effects on glomerular filtration rate, filtration fraction, creatinine clearance, or renal plasma flow. In multiple-dose studies in hypertensive patients, valsartan had no notable effects on total cholesterol , fasting triglycerides , fasting serum glucose, or uric acid.

Pharmacokinetics Valsartan peak plasma concentration is reached 2 to 4 hours after dosing. Valsartan shows biexponential decay kinetics following intravenous administration, with an average elimination half-life of about 6 hours. AUC and Cmax values of valsartan increase approximately linearly with increasing dose over the clinical dosing range. Valsartan does not accumulate appreciably in plasma following repeated administration.

In vitro metabolism studies involving recombinant CYP enzymes indicated that the CYP 2C9 isoenzyme is responsible for the formation of valerylhydroxy valsartan. Valsartan does not inhibit CYP isozymes at clinically relevant concentrations. CYP mediated drug interaction between valsartan and coadministered drugs are unlikely because of the low extent of metabolism.

Distribution The steady state volume of distribution of valsartan after intravenous administration is small 17 L , indicating that valsartan does not distribute into tissues extensively. Gender Pharmacokinetics of valsartan does not differ significantly between males and females.

Heart Failure The average time to peak concentration and elimination half-life of valsartan in heart failure patients are similar to those observed in healthy volunteers. AUC and Cmax values of valsartan increase linearly and are almost proportional with increasing dose over the clinical dosing range 40 to mg twice a day. The average accumulation factor is about 1. The apparent clearance of valsartan following oral administration is approximately 4.

Age does not affect the apparent clearance in heart failure patients. Renal Insufficiency There is no apparent correlation between renal function measured by creatinine clearance and exposure measured by AUC to valsartan in patients with different degrees of renal impairment.

Consequently, dose adjustment is not required in patients with mild-to-moderate renal dysfunction. Valsartan is not removed from the plasma by hemodialysis.

Generic Diovan is Now Available!

Do not take extra medicine to make up the missed dose. The explanation for this difference from generic findings is unclear. Valsartan has much greater affinity about 20,fold for the AT1 receptor than for diovan AT2 receptor. The initial dosage may be titrated upward within 7 days to 40 mg twice daily, with subsequent titrations to a target maintenance dose of mg twice daily as tolerated by the patient. In a clinical study involving 90 hypertensive pediatric patients 1 to 5 years of age with a similar study design, when will diovan be available as a generic, there was some evidence of effectiveness, but safety findings for which a relationship to treatment could not be etodolac 500 mg back pain mitigate against recommending use in this age group [see ADVERSE REACTIONS ].

Bystolic

Its action is will independent of the pathways for angiotensin II synthesis. Monitor serum lithium levels during generic use. Administration of valsartan to patients with essential hypertension results in a significant reduction of sitting, supineand standing systolic and diastolic blood pressure, usually with little or no orthostatic change. Renal and urinary disorders, and essential hypertension with or without obesity were the most common underlying causes of hypertension in children enrolled in this study. These results are summarized in the when diovan. When pregnancy is detected, when will diovan be available as a generic, discontinue Diovan as soon as possible.
