health-care reform and economic stress mean significant changes are ahead for aca- demic medicine.
"It is a remarkable time that we're in now. We are living through great change. In the next five or so years, the underpinnings of what we're used to doing are going to be chal- lenged," said Samuel O. Thier, MD, Professor of Medicine and Health Care Policy at Har- vard Medical School. Dr. Thier presented the keynote lecture, "Academic Medicine and Registration Desk Hours

AVAPRO (irbesartan):
Although any chloride deficit is generally mild and usually does not require specific treatment except under extraordinary circumstances (as in liver disease or renal disease), chloride replacement may be required in the treatment of metabolic alkalosis.
AVAPRO is indicated for the treatment of hypertension. It may be used alone or in combination with other antihypertensive agents.
Dilutional hyponatremia may occur in edematous patients in hot weather; appropriate therapy is water restriction, rather than administration of salt except in rare instances when the hyponatremia is life-threatening. In actual salt depletion, appropriate replacement is the therapy of choice.
Nephropathy in Type 2 Diabetic Patients

The choice of AVALIDE as initial therapy for hypertension should be based on an assessment of potential benefits and risks and may be shaped by considerations such as baseline blood pressure, target goal, and likelihood of achieving goal compared to monotherapy.
Increases in cholesterol and triglyceride levels may be associated with thiazide diuretic therapy.
DOSAGE AND ADMINISTRATION [See Dosage and Administration for AVAPRO and AVALIDE (2) in respective Full Prescribing Information Inserts.]
Hepatic Impairment
Volume- and Salt-Depleted Patients
Thiazides should be used with caution in patients with impaired hepatic function or progressive liver disease, since minor alterations of fluid and electrolyte balance may precipitate hepatic coma.
A lower initial dose of AVAPRO (75 mg) is recommended in patients with depletion of intravascular volume or salt (eg, patients treated vigorously with diuretics or on hemodialysis) [see Warnings and Precautions: Hypotension in Volume- or Salt-Depleted Patients].
Impaired Renal Function
AVAPRO (irbesartan) and AVALIDE (irbesartan-hydrochlorothiazide):
As a consequence of inhibiting the renin-angiotensin-aldosterone system, changes in renal function may be anticipated in susceptible individuals.

WARNINGS AND PRECAUTIONS
Fetal/Neonatal Morbidity and Mortality
Female patients of childbearing age should be told about the consequences of second- and third-trimester exposure to drugs that act on the renin- angiotensin system, and they should also be told that these consequences do not appear to have resulted from intrauterine drug exposure that has been limited to the first trimester. These patients should be asked to report pregnancies to their physicians as soon as possible.
Drugs that act directly on the renin-angiotensin system can cause fetal and neonatal morbidity and death when administered to pregnant women.
AVALIDE: [See Patient Counseling Information: Pregnancy.]
Several dozen cases have been reported in the world literature in patients who were taking angiotensin-converting-enzyme inhibitors. When pregnancy is detected, AVAPRO should be discontinued as soon as possible.
The use of drugs that act directly on the renin-angiotensin system during the second and third trimesters of pregnancy has been associated with fetal and neonatal injury, including hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death. Oligohydramnios No significant drug-drug pharmacokinetic (or pharmacodynamic) interactions have been found in interaction studies with hydrochlorothiazide, has also been reported, presumably resulting from decreased fetal renal function; oligohydramnios in this setting has been associated with fetal digoxin, warfarin, and nifedipine.

AVALIDE: [See Nonclinical Toxicology: Carcinogenesis, Mutagenesis, Impairment of Fertility.]
AVALIDE:
AVALIDE can cause fetal harm when administered to a pregnant woman. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus [see Use in Specific Populations]. In several dozen published cases, ACE inhibitor use during the second and third trimesters of pregnancy was associated with fetal and neonatal injury, including hypotension, Pregnancy Categories C (first trimester) and D (second and third trimesters)

Hypotension in Volume- or Salt-Depleted Patients
Excessive reduction of blood pressure was rarely seen (<0.1%) in patients with uncomplicated hypertension. Initiation of antihypertensive It is not known whether irbesartan is excreted in human milk, but irbesartan or some metabolite of irbesartan is secreted at low concentration in therapy may cause symptomatic hypotension in patients with intravascular volume- or sodium-depletion, eg, in patients treated vigorously with diuretics or in patients on dialysis.

AVALIDE: [See Use in Specific Populations: Nursing Mothers.]
If hypotension occurs, the patient should be placed in the supine position and, if necessary, given an intravenous infusion of normal saline. A transient hypotensive response is not a contraindication to further treatment, which usually can be continued without difficulty once the blood pressure has stabilized.
Irbesartan, in a study at a dose of up to 4.5 mg/kg/day, once daily, did not appear to lower blood pressure effectively in pediatric patients ages 6 to AVALIDE:

Hypersensitivity reactions to hydrochlorothiazide may occur in patients with or without a history of allergy or bronchial asthma, but are more likely in patients with such a history.
Systemic Lupus Erythematosus
AVAPRO has been evaluated for safety in more than 4300 patients with hypertension and about 5000 subjects overall. This experience includes Thiazide diuretics have been reported to cause exacerbation or activation of systemic lupus erythematosus.
1303 patients treated for over 6 months and 407 patients for 1 year or more. Treatment with AVAPRO was well-tolerated, with an incidence of adverse events similar to placebo. These events generally were mild and transient with no relationship to the dose of AVAPRO.
In placebo-controlled clinical trials, discontinuation of therapy due to a clinical adverse event was required in 3.3% of patients treated with AVAPRO, versus 4.5% of patients given placebo.
Lithium generally should not be given with thiazides. [See Drug Interactions.] In placebo-controlled clinical trials, the following adverse event experiences reported in at least 1% of patients treated with AVAPRO (n=1965) and Electrolyte and Metabolic Imbalances
at a higher incidence versus placebo (n=641), excluding those too general to be informative and those not reasonably associated with the use of drug because they were associated with the condition being treated or are very common in the treated population, include: diarrhea (3% vs 2%), dyspepsia/heartburn (2% vs 1%), and fatigue (4% vs 3%).
In double-blind clinical trials of various doses of irbesartan and hydrochlorothiazide, the incidence of hypertensive patients who developed hypokalemia (serum potassium <3.5 mEq/L) was 7.5% versus 6.0% for placebo; the incidence of hyperkalemia (serum potassium >5.7 mEq/L) was The following adverse events occurred at an incidence of 1% or greater in patients treated with irbesartan, but were at least as frequent or more <1.0% versus 1.7% for placebo. No patient discontinued due to increases or decreases in serum potassium. On average, the combination of frequent in patients receiving placebo: abdominal pain, anxiety/nervousness, chest pain, dizziness, edema, headache, influenza, musculoskeletal irbesartan and hydrochlorothiazide had no effect on serum potassium. Higher doses of irbesartan ameliorated the hypokalemic response to pain, pharyngitis, nausea/vomiting, rash, rhinitis, sinus abnormality, tachycardia, and urinary tract infection.
Irbesartan use was not associated with an increased incidence of dry cough, as is typically associated with ACE inhibitor use. In placebo-controlled studies, the incidence of cough in irbesartan-treated patients was 2.8% versus 2.7% in patients receiving placebo.
The incidence of hypotension or orthostatic hypotension was low in irbesartan-treated patients (0.4%), unrelated to dosage, and similar to the The following have been very rarely reported in post-marketing experience: urticaria; angioedema (involving swelling of the face, lips, pharynx, incidence among placebo-treated patients (0.2%). Dizziness, syncope, and vertigo were reported with equal or less frequency in patients receiving and/or tongue); increased liver function tests; jaundice; and hepatitis. Hyperkalemia has been rarely reported.

Rare cases of rhabdomyolysis have been reported in patients receiving angiotensin II receptor blockers.
In addition, the following potentially important events occurred in less than 1% of the 1965 patients and at least 5 patients (0.3%) receiving irbesartan in clinical studies, and those less frequent, clinically significant events (listed by body system). It cannot be determined whether these events were causally related to irbesartan: The following adverse reactions have been identified during post-approval use of AVALIDE. Because these reactions are reported voluntarily from a Body as a Whole: fever, chills, facial edema, upper extremity edema population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Decisions to include these reactions in labeling are typically based on one or more of the following factors: (1) seriousness of the reaction, Cardiovascular: flushing, hypertension, cardiac murmur, myocardial infarction, angina pectoris, arrhythmic/conduction disorder, cardio-respiratory (2) frequency of reporting, or (3) strength of causal connection to AVALIDE.

Dermatologic: pruritus, dermatitis, ecchymosis, erythema face, urticaria Hyperkalemia has been rarely reported.
Endocrine/Metabolic/Electrolyte Imbalances: sexual dysfunction, libido change, gout Very rare cases of jaundice have been reported with irbesartan.
Gastrointestinal: constipation, oral lesion, gastroenteritis, flatulence, abdominal distention Rare cases of rhabdomyolysis have been reported in patients receiving angiotensin II receptor blockers.
Musculoskeletal/Connective Tissue: extremity swelling, muscle cramp, arthritis, muscle ache, musculoskeletal chest pain, joint stiffness, bursitis, Nervous System: sleep disturbance, numbness, somnolence, emotional disturbance, depression, paresthesia, tremor, transient ischemic attack, cerebrovascular accident Renal/Genitourinary: abnormal urination, prostate disorder In controlled clinical trials, clinically important differences in laboratory tests were rarely associated with administration of AVAPRO.
Respiratory: epistaxis, tracheobronchitis, congestion, pulmonary congestion, dyspnea, wheezing Creatinine, Blood Urea Nitrogen: Minor increases in blood urea nitrogen (BUN) or serum creatinine were observed in less than 0.7% of patients with essential hypertension treated with AVAPRO alone versus 0.9% on placebo. [See Warnings and Precautions: Impaired Renal Function.] Special Senses: vision disturbance, hearing abnormality, ear infection, ear pain, conjunctivitis, other eye disturbance, eyelid abnormality, ear abnormality Hematologic: Mean decreases in hemoglobin of 0.2 g/dL were observed in 0.2% of patients receiving AVAPRO compared to 0.3% of placebo-treated Nephropathy in Type 2 Diabetic Patients
patients. Neutropenia (<1000 cells/mm3) occurred at similar frequencies among patients receiving AVAPRO (0.3%) and placebo-treated patients (0.5%).
In clinical studies in patients with hypertension and type 2 diabetic renal disease, the adverse drug experiences were similar to those seen in Nephropathy in Type 2 Diabetic Patients
patients with hypertension with the exception of an increased incidence of orthostatic symptoms (dizziness, orthostatic dizziness, and orthostatic hypotension) observed in IDNT (proteinuria *900 mg/day, and serum creatinine ranging from 1.0-3.0 mg/dL). In this trial, orthostatic symptoms Hyperkalemia: In IDNT (proteinuria *900 mg/day, and serum creatinine ranging from 1.0-3.0 mg/dL), the percent of patients with hyperkalemia occurred more frequently in the AVAPRO (irbesartan) group (dizziness 10.2%, orthostatic dizziness 5.4%, orthostatic hypotension 5.4%) than in the (>6 mEq/L) was 18.6% in the AVAPRO group versus 6.0% in the placebo group.

AVALIDE:
Clinical Trials Experience
In controlled clinical trials, clinically important changes in standard laboratory parameters were rarely associated with administration of AVALIDE.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly Creatinine, Blood Urea Nitrogen: Minor increases in blood urea nitrogen (BUN) or serum creatinine were observed in 2.3% and 1.1%, respectively, compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.The adverse reaction information from clinical of patients with essential hypertension treated with AVALIDE alone. No patient discontinued taking AVALIDE due to increased BUN. One patient trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.
discontinued taking AVALIDE due to a minor increase in serum creatinine.
Liver Function Tests: Occasional elevations of liver enzymes and/or serum bilirubin have occurred. In patients with essential hypertension treated with AVALIDE alone, one patient was discontinued due to elevated liver enzymes.
AVALIDE Tablets has been evaluated for safety in 1694 patients treated for essential hypertension in 6 clinical trials. In Studies I through IV with AVALIDE, no adverse events peculiar to this combination drug product have been observed. Adverse events have been limited to those that were Serum Electrolytes: [See Warnings and Precautions.] reported previously with irbesartan or hydrochlorothiazide (HCTZ). The overall incidence of adverse events was similar with the combination and placebo. In general, treatment with AVALIDE was well tolerated. For the most part, adverse events have been mild and transient in nature and have AVAPRO: [See Warnings and Precautions: Drug Interactions.]
not required discontinuation of therapy. In controlled clinical trials, discontinuation of AVALIDE therapy due to clinical adverse events was required in only 3.6%. This incidence was significantly less (p=0.023) than the 6.8% of patients treated with placebo who discontinued therapy.
AVALIDE:
In these double-blind controlled clinical trials, the following adverse events reported with AVALIDE occurred in *1% of patients, and more often on the irbesartan-hydrochlorothiazide combination than on placebo, regardless of drug relationship: No significant drug-drug interactions have been reported with irbesartan. [See Clinical Pharmacology.]Hydrochlorothiazide When administered concurrently the following drugs may interact with thiazide diuretics: Alcohol, Barbiturates, or Narcotics: potentiation of orthostatic hypotension may occur.
Antidiabetic Drugs (oral agents and insulin): dosage adjustment of the antidiabetic drug may be required.
Other Antihypertensive Drugs: additive effect or potentiation.
Cholestyramine and Colestipol Resins: absorption of hydrochlorothiazide is impaired in the presence of anionic exchange resins. Single doses of either cholestyramine or colestipol resins bind the hydrochlorothiazide and reduce its absorption from the gastrointestinal tract by up to 85% and 43%, respectively.
Corticosteroids, ACTH: intensified electrolyte depletion, particularly hypokalemia.
Pressor Amines (eg, Norepinephrine): possible decreased response to pressor amines but not sufficient to preclude their use.
Skeletal Muscle Relaxants, Nondepolarizing (eg, Tubocurarine): possible increased responsiveness to the muscle relaxant.
Lithium: should not generally be given with diuretics. Diuretic agents reduce the renal clearance of lithium and add a high risk of lithium toxicity.
Refer to the package insert for lithium preparations before use of such preparations with AVALIDE. [See Warnings and Precautions.] Non-steroidal Anti-inflammatory Drugs: in some patients, the administration of a non-steroidal anti-inflammatory agent can reduce the diuretic, natriuretic, and antihypertensive effects of loop, potassium-sparing and thiazide diuretics. Therefore, when AVALIDE 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.

In several dozen published cases, ACE inhibitor use during the second and third trimesters of pregnancy was associated with fetal and neonatal injury, including hypotension, neonatal skull hypoplasia, anuria, reversible or irreversible renal failure, and death. Oligohydramnios was also reported, presumably from decreased fetal renal function. In this setting, oligohydramnios was associated with fetal limb contractures, craniofacial Other adverse events that have been reported with irbesartan, without regard to causality, are listed below: deformation, and hypoplastic lung development. Prematurity, intrauterine growth retardation, and patent ductus arteriosus were also reported, Body as a Whole: fever, chills, orthostatic effects, facial edema, upper extremity edema although it is not clear whether these occurrences were due to exposure to the drug.

In pregnant rats given irbesartan at doses greater than the maximum recommended human dose (MRHD), fetuses showed increased incidences of renal pelvic cavitation, hydroureter and/or absence of renal papilla. Subcutaneous edema also occurred in fetuses at doses about 4 times the MRHD (based on body surface area). These anomalies occurred when pregnant rats received Other adverse events that have been reported with hydrochlorothiazide, without regard to causality, are listed below: irbesartan through Day 20 of gestation but not when drug was stopped on gestation day 15.

The degree to which hydrochlorothiazide is removed by hemodialysis has not been established. The oral LD50 of hydrochlorothiazide is greater than 10 g/kg in both mice and rats.
No significant drug-drug pharmacokinetic (or pharmacodynamic) interactions have been found in interaction studies with hydrochlorothiazide, digoxin, warfarin, and nifedipine.

Angiotensin II is a potent vasoconstrictor formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme (ACE, kininase II).
Angiotensin II is the principal pressor agent of the renin-angiotensin system (RAS) and also stimulates aldosterone synthesis and secretion by In separate studies of patients receiving maintenance doses of warfarin, hydrochlorothiazide, or digoxin, irbesartan administration for 7 days had adrenal cortex, cardiac contraction, renal resorption of sodium, activity of the sympathetic nervous system, and smooth muscle cell growth.

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.
Irbesartan does not inhibit ACE or renin or affect other hormone receptors or ion channels known to be involved in the cardiovascular regulation of blood pressure and sodium homeostasis. Because irbesartan does not inhibit ACE, it does not affect the response to bradykinin; whether this has No carcinogenicity 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). Irbesartan-hydrochlorothiazide was negative in tests for induction of chromosomal aberrations (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.
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. Indirectly, the diuretic action of hydrochlorothiazide reduces plasma volume, with consequent increases in plasma renin activity, increases in aldosterone secretion, increases in urinary potassium loss, and decreases in serum No evidence of carcinogenicity was observed when irbesartan was administered at doses of up to 500/1000 mg/kg/day (males/females, potassium. The renin-aldosterone link is mediated by angiotensin II, so coadministration of an angiotensin II receptor antagonist tends to reverse respectively) in rats and 1000 mg/kg/day in mice for up to 2 years.

Irbesartan is an orally active agent that does not require biotransformation into an active form. The oral absorption of irbesartan is rapid and complete with an average absolute bioavailability of 60% to 80%. Following oral administration of irbesartan, peak plasma concentrations of Animal Toxicology and/or Pharmacology
irbesartan are attained at 1.5 to 2 hours after dosing. Food does not affect the bioavailability of irbesartan.
Reproductive Toxicology Studies
Irbesartan exhibits linear pharmacokinetics over the therapeutic dose range.
AVAPRO: [See Warnings and Precautions: Fetal/Neonatal Morbidity and Mortality.]
The terminal elimination half-life of irbesartan averaged 11 to 15 hours. Steady-state concentrations are achieved within 3 days. Limited accumulation of irbesartan (<20%) is observed in plasma upon repeated once-daily dosing.
When pregnant rats were treated with irbesartan from day 0 to day 20 of gestation (oral doses of 50, 180, and 650 mg/kg/day), increased incidences of renal pelvic cavitation, hydroureter and/or absence of renal papilla were observed in fetuses at doses *50 mg/kg/day (approximately equivalent to the maximum recommended human dose [MRHD], 300 mg/day, on a body surface area basis). Subcutaneous edema was observed in fetuses at doses *180 mg/kg/day (about 4 times the MRHD on a body surface area When plasma levels have been followed for at least 24 hours, the plasma half-life has been observed to vary between 5.6 and 14.8 hours.

Irbesartan was found to cross the placental barrier in rats and rabbits.
Irbesartan is metabolized via glucuronide conjugation and oxidation. Following oral or intravenous administration of 14C-labeled irbesartan, more PATIENT COUNSELING INFORMATION
than 80% of the circulating plasma radioactivity is attributable to unchanged irbesartan. The primary circulating metabolite is the inactive irbesartan glucuronide conjugate (approximately 6%). The remaining oxidative metabolites do not add appreciably to irbesartan's pharmacologic activity.
AVAPRO: [See Warnings and Precautions: Information for Patients.]
Irbesartan and its metabolites are excreted by both biliary and renal routes. Following either oral or intravenous administration of 14C-labeled irbesartan, about 20% of radioactivity is recovered in the urine and the remainder in the feces, as irbesartan or irbesartan glucuronide.
In vitro studies of irbesartan oxidation by cytochrome P450 isoenzymes indicated irbesartan was oxidized primarily by 2C9; metabolism by 3A4 was Female patients of childbearing age should be told that use of drugs like AVALIDE during the second or third trimesters of pregnancy can cause negligible. Irbesartan was neither metabolized by, nor did it substantially induce or inhibit, isoenzymes commonly associated with drug metabolism serious problems in the fetus and infant including: low blood pressure, poor development of skull bones, kidney failure, and death. These effects (1A1, 1A2, 2A6, 2B6, 2D6, 2E1). There was no induction or inhibition of 3A4.
have not occurred with drug exposure limited to the first trimester. Women using AVALIDE who become pregnant should notify their physician as soon as possible.
Hydrochlorothiazide is not metabolized but is eliminated rapidly by the kidney. At least 61% of the oral dose is eliminated unchanged within 24 hours.
Patients using AVALIDE should be told that they may feel lightheaded, especially during the first days of use. Patients should inform their physician if they feel lightheaded or faint. If fainting occurs, the patient should stop using AVALIDE and contact the prescribing doctor.
Patients using AVALIDE should be told that getting dehydrated can lower their blood pressure too much and lead to lightheadedness and possible AVAPRO and AVALIDE:
fainting. Dehydration may occur with excessive sweating, diarrhea, or vomiting and with not drinking enough liquids.
Irbesartan Irbesartan is 90% bound to serum proteins (primarily albumin and 1-acid glycoprotein) with negligible binding to cellular components of blood. The Manufactured by: Bristol-Myers Squibb Company, Princeton, New Jersey 08543 USA average volume of distribution is 53 to 93 liters. Total plasma and renal clearances are in the range of 157 to 176 mL/min and 3.0 to 3.5 mL/min, respectively. With repetitive dosing, irbesartan accumulates to no clinically relevant extent.
Distributed by: Bristol-Myers Squibb Sanofi-Synthelabo Partnership, New York, New York 10016 Studies in animals indicate that radiolabeled irbesartan weakly crosses the blood-brain barrier and placenta. Irbesartan is excreted in the milk of lactating rats.
AVALIDE:

Hydrochlorothiazide crosses the placental but not the blood-brain barrier and is excreted in breast milk.

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. In studies of hypertensive patients, there was no gender difference in half-life or accumulation, but somewhat higher plasma concen- trations of irbesartan were observed in females (11% to 44%). No gender-related dosage adjustment is necessary.
Geriatric
In elderly subjects (age 65 to 80 years), irbesartan elimination half-life was not significantly altered, but AUC and Cmax values were about 20% to
50% greater than those of young subjects (age 18 to 40 years). No dosage adjustment is necessary in the elderly.
Race
In healthy black subjects, irbesartan AUC values were approximately 25% greater than whites; there were no differences in Cmax values.

t In placebo-controlled hypertension studies, there were no significant differences in adverse events (AEs) between AVAPRO and placebo. Adverse events that occurred in at least 1% of patients treated with AVAPRO and at a higher incidence AVAPRO (irbesartan) is indicated for the treatment of vs placebo included diarrhea (3% vs. 2%), dyspepsia/heartburn hypertension.
