CLINICALPHARMACOLOGY
MechanismofAction
CADUET
CADUET isacombinationoftwodrugs,adihydropyridinecalciumantagonist (calcium
ionantagonistor slow-channelblocker) amlodipine(antihypertensive/antianginal agent)
andanHMG-CoAreductaseinhibitor atorvastatin (cholesterolloweringagent).The
amlodipinecomponentofCADUETinhibitsthetransmembrane influxofcalciumionsinto
vascularsmoothmuscleand cardiacmuscle. TheatorvastatincomponentofCADUETisa
selective, competitiveinhibitor ofHMG-CoAreductase, the rate-limitingenzymethat
converts 3-hydroxy-3-methylglutaryl-coenzymeAtomevalonate,a precursor ofsterols,
includingcholesterol.
The Amlodipine ComponentofCADUET
Experimentaldatasuggestthatamlodipine bindstobothdihydropyridine and
nondihydropyridine bindingsites.Thecontractileprocessesof cardiac muscle andvascular
smoothmusclearedependentupon the movementofextracellularcalciumionsintothese
cellsthrough specificionchannels. Amlodipineinhibits calciumion influx across cell
membranesselectively, withagreatereffectonvascular smoothmusclecells than on
cardiac muscle cells.Negativeinotropiceffectscanbedetectedinvitrobutsucheffects
havenotbeenseeninintactanimals attherapeuticdoses. Serum calciumconcentrationis
not affectedbyamlodipine.
Caduet®Tablets,Israel, 29July2007
WithinthephysiologicpHrange, amlodipineis anionizedcompound (pKa=8.6), and its
kinetic interactionwiththe calciumchannel receptorischaracterizedbyagradualrateof
association anddissociationwith the receptor binding site, resulting inagradualonsetof
effect.
Amlodipineisaperipheral arterialvasodilator thatactsdirectly onvascularsmoothmuscle
tocausea reductioninperipheral vascularresistanceandreductioninbloodpressure.
The precise mechanismsbywhichamlodipine relievesanginahavenot beenfully
delineated, but arethoughttoinclude thefollowing:
ExertionalAngina:Inpatients withexertional angina,amlodipine reduces thetotal
peripheral resistance(afterload) against which the heartworksand reducestheratepressure
product,andthusmyocardialoxygendemand, atany givenlevel ofexercise.
VasospasticAngina:Amlodipinehasbeendemonstratedtoblock constrictionand restore
blood flowincoronaryarteriesand arteriolesinresponsetocalcium,potassium
epinephrine,serotonin, andthromboxaneA
analoginexperimental animalmodelsand in
humancoronaryvesselsinvitro. This inhibition ofcoronaryspasmisresponsibleforthe
effectiveness ofamlodipine in vasospastic (Prinzmetal’s orvariant)angina.
The Atorvastatin Component of CADUET
Cholesterolandtriglycerides circulatein thebloodstreamaspartoflipoprotein complexes.
Withultracentrifugation,thesecomplexesseparateinto HDL(high-densitylipoprotein),
IDL(intermediate-densitylipoprotein), LDL (low-densitylipoprotein),andVLDL(very-
low-densitylipoprotein)fractions.Triglycerides (TG)and cholesterol inthe liverare
incorporatedintoVLDLand releasedintothe plasmafor delivery to peripheral tissues.
LDLisformed fromVLDL and is catabolizedprimarilythroughthe high-affinityLDL
receptor.
Clinical andpathologic studies showthatelevated plasmalevelsof totalcholesterol(total-
C),LDL-cholesterol(LDL-C), andapolipoproteinB (apoB)promotehuman
atherosclerosis andarerisk factorsfor developingcardiovascular disease,whileincreased
levelsofHDL-Care associatedwithadecreasedcardiovascular risk.
Epidemiologicinvestigationshaveestablishedthat cardiovascularmorbidityand mortality
varydirectlywiththe leveloftotal-CandLDL-C,andinverselywiththe levelofHDL-C.
Inanimalmodels,atorvastatinlowers plasmacholesterolandlipoproteinlevelsby
inhibitingHMG-CoA reductase andcholesterolsynthesis inthe liverandby increasing the
numberofhepaticLDLreceptorsonthe cell-surfacetoenhance uptakeandcatabolismof
LDL; atorvastatinalsoreducesLDLproductionandthenumberofLDL particles.
Caduet®Tablets,Israel, 29July2007
Atorvastatinreduces total-C,LDL-C,and apoB inpatientswith homozygous and
heterozygousfamilialhypercholesterolemia(FH), nonfamilial forms of
hypercholesterolemia,andmixed dyslipidemia.Atorvastatinalsoreduces VLDL-CandTG
and producesvariableincreases in HDL-Candapolipoprotein A-1.Atorvastatinreduces
total-C,LDL-C, VLDL-C, apoB,TG,andnon-HDL-C,andincreasesHDL-Cinpatients
withisolatedhypertriglyceridemia.Atorvastatinreduces intermediate densitylipoprotein

PharmacokineticsandMetabolism
Absorption
Studieswithamlodipine:Afteroral administrationoftherapeuticdosesofamlodipine
alone, absorptionproduces peakplasmaconcentrationsbetween6and12hours.Absolute
bioavailabilityhas been estimated to bebetween64% and 90%.The bioavailability of
amlodipinewhenadministeredaloneis notalteredbythepresenceoffood.
Studies withatorvastatin:Afteroral administration alone,atorvastatinisrapidly absorbed;
maximumplasmaconcentrations occurwithin1to2 hours.Extentofabsorptionincreases
inproportionto atorvastatindose. The absolutebioavailabilityof atorvastatin(parentdrug)
is approximately14%and the systemicavailability ofHMG-CoA reductase inhibitory
activityis approximately30%. Thelow systemicavailabilityisattributedtopresystemic
clearancein gastrointestinalmucosa and/orhepatic first-passmetabolism. Althoughfood
decreasestherateandextentofdrugabsorptionbyapproximately25%and9%,
respectively,as assessedbyCmaxand AUC,LDL-Creduction is similarwhether
atorvastatinisgivenwithorwithoutfood.Plasmaatorvastatinconcentrationsare lower
(approximately 30%forCmaxand AUC)followingevening drug administration compared
withmorning.However,LDL-Creductionisthesameregardlessofthetimeofdayofdrug
administration(seeDOSAGE ANDADMINISTRATION).
Studies with CADUET:FollowingoraladministrationofCADUETpeakplasma
concentrationsofamlodipineandatorvastatinareseenat 6to12hoursand1to2hours
post dosing, respectively. The rate andextentofabsorption (bioavailability)ofamlodipine
and atorvastatinfromCADUETarenotsignificantlydifferent fromthebioavailabilityof
amlodipineand atorvastatinadministeredseparately (seeabove).
Caduet®Tablets,Israel, 29July2007
The bioavailabilityofamlodipine from CADUETwas notaffectedbyfood. Althoughfood
decreases the rateandextentofabsorptionofatorvastatinfrom CADUET by
approximately32%and 11%, respectively, as it does with atorvastatinwhengiven alone.
LDL-C reduction issimilar whether atorvastatinis givenwithorwithoutfood.
Distribution
Studieswithamlodipine:Ex vivostudieshave shownthatapproximately 93%ofthe
circulatingamlodipinedrugis boundtoplasmaproteinsinhypertensivepatients.
Steady-stateplasmalevelsofamlodipinearereached after 7to8 days ofconsecutivedaily
dosing.
Studies with atorvastatin:Meanvolumeofdistributionofatorvastatinisapproximately381
liters. Atorvastatinis ≥98% bound toplasmaproteins. A blood/plasma ratio of
approximately0.25indicatespoor drugpenetrationinto red bloodcells.Based on
observationsin rats,atorvastatincalciumislikelyto besecreted inhumanmilk (see
CONTRAINDICATIONS, Pregnancyand Lactation,andPRECAUTIONS,Nursing
Mothers).
Metabolism
Studieswithamlodipine:Amlodipineisextensively(about 90%)convertedtoinactive
metabolites via hepaticmetabolism.
Studies withatorvastatin:Atorvastatinis extensivelymetabolized toortho- and
parahydroxylatedderivativesandvarious beta-oxidationproducts.In vitroinhibitionof
HMG-CoA reductasebyortho- and parahydroxylatedmetabolites isequivalent to thatof
atorvastatin.Approximately70%ofcirculating inhibitoryactivityforHMG-CoAreductase
isattributedtoactivemetabolites.Invitrostudiessuggesttheimportanceof atorvastatin
metabolismbycytochromeP450 3A4, consistentwith increased plasmaconcentrationsof
atorvastatinin humans followingcoadministrationwitherythromycin,aknowninhibitorof
thisisozyme(seePRECAUTIONS, DrugInteractions).Inanimals,the ortho-hydroxy
metaboliteundergoesfurther glucuronidation.
Excretion
Studieswithamlodipine:Eliminationfromtheplasmaisbiphasicwithaterminal
elimination half-lifeofabout30-50hours. Tenpercent oftheparent amlodipine compound
and 60% ofthemetabolites ofamlodipineareexcretedintheurine.
Studies withatorvastatin:Atorvastatinand its metabolites are eliminatedprimarilyin bile
following hepaticand/or extra-hepaticmetabolism;however,the drugdoesnotappearto
undergo enterohepaticrecirculation.Meanplasmaeliminationhalf-lifeofatorvastatinin

SpecialPopulations
Geriatric
Studieswithamlodipine:Elderly patients havedecreasedclearanceofamlodipine witha
resulting increaseinAUC ofapproximately40-60%, anda lower initialdose ofamlodipine
mayberequired.
Studies with atorvastatin:Plasmaconcentrationsofatorvastatinarehigher(approximately
40%forCmaxand30% for AUC) inhealthy elderly subjects(age ≥65years) thaninyoung
adults. Clinical data suggesta greaterdegreeofLDL-lowering atany dose ofatorvastatin
inthe elderlypopulationcomparedtoyoungeradults (seePRECAUTIONSsection,
Geriatric Use).
Pediatric
Studieswithamlodipine: Sixty-twohypertensive patientsaged6to17yearsreceiveddoses
ofamlodipinebetween1.25mgand20mg. Weight-adjustedclearanceand volumeof
distributionwere similartovaluesinadults.
Studies withatorvastatin:Pharmacokinetic datain thepediatricpopulationare not
available.
Gender
Studies withatorvastatin:Plasmaconcentrationsofatorvastatinin womendifferfromthose
inmen (approximately20% higherforCmaxand10% lower for AUC); however,thereis
noclinicallysignificantdifference inLDL-Creductionwithatorvastatinbetweenmen and
women.
Renal Insufficiency
Studieswithamlodipine:Thepharmacokineticsofamlodipinearenot significantly
influencedbyrenal impairment. Patientswith renalfailuremay thereforereceivetheusual
initial amlodipine dose.
Caduet®Tablets,Israel, 29July2007
Studies withatorvastatin:Renal disease has noinfluenceontheplasmaconcentrationsor
LDL-C reductionofatorvastatin;thus, doseadjustmentofatorvastatin inpatientswith
renal dysfunction is notnecessary(seeDOSAGE ANDADMINISTRATION).
Hemodialysis
While studieshavenotbeenconductedinpatientswithend-stagerenal disease,
hemodialysisisnot expectedtosignificantlyenhanceclearance ofatorvastatin and/or
amlodipinesince bothdrugsare extensivelyboundtoplasmaproteins.
Hepatic Insufficiency
Studieswithamlodipine:Elderly patients and patientswithhepaticinsufficiencyhave
decreased clearanceofamlodipinewitharesultingincrease inAUC ofapproximately
40-60%, anda lowerinitial dosemayberequired.
Studies withatorvastatin:Inpatientswithchronic alcoholicliverdisease, plasma
concentrationsofatorvastatinaremarkedly increased.Cmax andAUCareeach4-fold
greaterinpatientswith Childs-Pugh Adisease.CmaxandAUCofatorvastatinare
approximately16-foldand11-foldincreased, respectively,inpatients with Childs-PughB
disease(seeCONTRAINDICATIONS).
Heart Failure
Studieswithamlodipine:Inpatients withmoderateto severeheartfailure, theincreasein
AUCfor amlodipinewas similar tothatseeninthe elderlyandinpatients withhepatic
insufficiency.
Pharmacodynamics
HemodynamicEffects of Amlodipine:Followingadministrationoftherapeuticdosesto
patients withhypertension,amlodipineproduces vasodilationresultinginareductionof
supineand standingblood pressures.Thesedecreases in blood pressurearenot
accompaniedbya significant changeinheartrateorplasmacatecholamine levelswith
chronicdosing.Althoughtheacuteintravenousadministrationofamlodipinedecreases
arterialblood pressureandincreasesheart rateinhemodynamicstudiesof patients with
chronicstable angina,chronicadministration oforalamlodipineinclinicaltrialsdid not
lead toclinicallysignificant changes inheartrate orbloodpressures in normotensive
patients withangina.
Caduet®Tablets,Israel, 29July2007
Withchronic oncedaily oraladministration ofamlodipine,antihypertensiveeffectiveness
ismaintainedforatleast24hours. Plasmaconcentrationscorrelate witheffectinboth
youngandelderlypatients. The magnitudeofreductioninbloodpressurewithamlodipine
is alsocorrelatedwith theheightofpretreatment elevation; thus, individualswithmoderate
hypertension(diastolicpressure105-114 mmHg)hadabout a 50% greaterresponsethan
patients withmildhypertension (diastolic pressure 90-104mmHg).Normotensivesubjects
experiencednoclinically significantchangein blood pressures(+1/–2mmHg).
In hypertensivepatientswithnormalrenalfunction,therapeutic doses ofamlodipine
resultedina decreaseinrenal vascularresistanceandanincreaseinglomerularfiltration
rateandeffectiverenal plasmaflowwithoutchangein filtrationfractionorproteinuria.
Aswith other calciumchannel blockers, hemodynamicmeasurementsof cardiacfunction

whenadministeredinthetherapeutic doserangetointactanimalsandman,evenwhen
co-administeredwithbeta-blockers toman.Similar findings,however,havebeenobserved
innormals orwell-compensatedpatients with heartfailure withagentspossessing
significantnegativeinotropic effects.
ElectrophysiologicEffects of Amlodipine:Amlodipinedoes not changesinoatrial nodal
functionoratrioventricularconductioninintactanimals orman.Inpatients withchronic
stable angina,intravenousadministrationof10mgdidnot significantlyalterA-H andH-V
conductionandsinus node recoverytimeafter pacing.Similar results wereobtainedin
patientsreceivingamlodipineandconcomitant betablockers. Inclinical studiesinwhich
amlodipinewasadministeredincombinationwithbeta-blockers topatients witheither
hypertension or angina,no adverseeffects on electrocardiographicparameterswere
observed.Inclinicaltrialswith anginapatientsalone, amlodipinetherapydidnot alter
electrocardiographicintervals orproduce higherdegrees ofAVblocks.

averaging about 12/6mmHginthestandingpositionand 13/7mmHgin the supine position
in patientswithmild tomoderatehypertension.Maintenance ofthebloodpressureeffect
overthe 24-hour dosingintervalwas observed,withlittledifferenceinpeakandtrough

CONTRAINDICATIONS
CADUET containsatorvastatinandis thereforecontraindicatedinpatientswithactiveliver
diseaseorunexplainedpersistentelevationsofserumtransaminases.
CADUETiscontraindicated in patients withknown hypersensitivitytoany componentof
thismedication.
Pregnancy andLactation
Atherosclerosisis achronicprocessand discontinuation oflipid-lowering drugsduring
pregnancyshould have littleimpactonthe outcome oflong-termtherapyofprimary
hypercholesterolemia.Cholesterol andother productsofcholesterol biosynthesisare
essential components for fetaldevelopment (including synthesis ofsteroidsandcell
membranes). Since HMG-CoAreductaseinhibitorsdecrease cholesterolsynthesis and
possibly the synthesisof otherbiologicallyactivesubstancesderivedfromcholesterol, they
maycause fetalharmwhenadministeredtopregnant women.Therefore,HMG-CoA
reductaseinhibitorsare contraindicatedduringpregnancyandinnursingmothers.

WARNINGS
IncreasedAnginaand/orMyocardialInfarction
Rarely, patients,particularlythose withsevereobstructive coronaryarterydisease,have
developeddocumentedincreased frequency,duration and/orseverityofanginaor acute
myocardialinfarction onstartingcalciumchannelblocker therapy oratthetimeofdosage
increase. The mechanismofthiseffecthasnotbeenelucidated.
Liver Dysfunction
HMG-CoA reductaseinhibitors,likesomeother lipid-loweringtherapies,have been
associatedwithbiochemicalabnormalitiesofliverfunction.Persistent elevations(>3
timestheupper limit ofnormal[ULN] occurring on 2ormoreoccasions) inserum
transaminasesoccurred in0.7%ofpatientswhoreceivedatorvastatin in clinical
trials. Theincidence of theseabnormalitieswas 0.2%,0.2%,0.6%,and2.3%for10,
20,40,and 80mg, respectively.
In clinicaltrials inpatients takingatorvastatinthefollowinghasbeenobserved. Onepatient

werenot associatedwith jaundiceorotherclinical signsor symptoms. Upondose

Caduet®Tablets,Israel, 29July2007
pretreatmentlevelswithoutsequelae. Eighteenof30 patients,with persistentLFT
elevationscontinued treatmentwithareduceddose ofatorvastatin.
Itisrecommended thatliverfunctiontestsbe performed priortoandat12weeks
followingboththe initiationof therapyandany elevation of dose,andperiodically
(e.g., semiannually) thereafter. Liverenzymechanges generally occur inthe first 3
monthsoftreatmentwith atorvastatin.Patientswhodevelop increasedtransaminaselevels
shouldbemonitored untilthe abnormalitiesresolve. ShouldanincreaseinALTorASTof
>3timesULNpersist,reduction ofdoseorwithdrawalofCADUETis recommended.
CADUETshould beused withcaution inpatients who consumesubstantialquantitiesof
alcohol and/orhaveahistoryofliver disease.Activeliver disease or unexplainedpersistent
transaminaseelevations arecontraindications to the useofCADUET (see
CONTRAINDICATIONS).
SkeletalMuscle
Rarecases of rhabdomyolysiswithacuterenal failure secondarytomyoglobinuria
havebeenreportedwiththeatorvastatin componentofCADUETand with other
drugs intheHMG-CoAreductase inhibitor class.
Uncomplicatedmyalgiahas beenreportedinatorvastatin-treatedpatients(seeADVERSE
REACTIONS). Myopathy,definedasmuscleaches ormuscleweakness inconjunction
withincreases increatinephosphokinase (CPK) values>10timesULN,shouldbe
consideredinanypatientwith diffuse myalgias, muscletenderness orweakness, and/or
marked elevation ofCPK.Patientsshould beadvisedtoreportpromptlyunexplained
muscle pain,tenderness or weakness,particularlyifaccompaniedbymalaiseorfever.
CADUET therapy shouldbediscontinuedifmarkedlyelevatedCPK levelsoccuror
myopathyisdiagnosedor suspected.
The riskofmyopathyduringtreatment withdrugsintheHMG-CoA reductase inhibitor
classis increasedwithconcurrentadministration ofcyclosporine, fibricacidderivatives,
erythromycin, lipid-modifyingdosesof niacin,orazoleantifungals.Physiciansconsidering
combinedtherapy withCADUET andfibricacidderivatives, erythromycin,
immunosuppressive drugs,azoleantifungals, orlipid-loweringdoses ofniacinshould
carefullyweighthe potential benefits andrisks andshouldcarefullymonitor patientsfor
anysignsorsymptomsofmuscle pain, tenderness, or weakness,particularlyduringthe
initial months oftherapyand duringanyperiodsofupward dosagetitration ofeither drug.
Therefore, lowerstartingandmaintenance doses oftheatorvastatincomponentshould also be
consideredwhen taken concomitantlywith the aforementioneddrugs. (Seesection4.5Interaction
with other medicinal productsand otherformsofinteraction) . Periodiccreatine
phosphokinase (CPK) determinationsmaybeconsideredinsuchsituations,but there isno
assurancethatsuchmonitoringwillprevent the occurrenceofseveremyopathy.
Inpatients taking CADUET, therapyshouldbe temporarilywithheld or discontinued
in any patient with anacute,serious conditionsuggestiveofa myopathyor havinga
riskfactorpredisposingtothedevelopmentofrenal failure secondary to
Caduet®Tablets,Israel, 29July2007
rhabdomyolysis (e.g., severeacuteinfection, hypotension, majorsurgery,trauma,
severemetabolic,endocrineandelectrolyte disorders,anduncontrolled seizures).
PRECAUTIONS
General
Sincethevasodilation inducedbytheamlodipine component ofCADUETis gradualin
onset,acute hypotensionhas rarelybeenreported after oraladministrationofamlodipine.
Nonetheless, cautionshouldbeexercisedwhenadministering CADUET as withanyother
peripheral vasodilator particularlyinpatientswith severeaorticstenosis.
Beforeinstituting therapy withCADUET,an attemptshouldbe made to control
hypercholesterolemiawithappropriate diet,exercise, and weightreductioninobese
patients,and to treat otherunderlyingmedical problems(seeINDICATIONSAND
USAGE).
Use in PatientswithCongestive HeartFailure
In general,calciumchannelblockersshouldbe usedwithcaution inpatients withheart
failure.TheamlodipinecomponentofCADUET(5-10 mgperday)hasbeenstudiedina
placebo-controlledtrialof1153patients withNYHA ClassIIIorIVheart failure (see
CLINICALPHARMACOLOGY)onstabledoses ofACE inhibitor, digoxin,and
diuretics.Follow-up wasatleast6 months, withameanofabout14months.Therewasno
overalladverseeffect onsurvivalor cardiacmorbidity (as defined bylife-threatening
arrhythmia, acutemyocardialinfarction,orhospitalization forworsenedheartfailure).
Amlodipinehasbeencomparedto placeboin four8-12weekstudies ofpatientswith
NYHAclassII/III heartfailure,involvinga totalof697 patients.Inthesestudies,therewas
noevidenceofworsenedheartfailurebasedon measures ofexercisetolerance, NYHA
classification,symptoms, orLVEF.
Beta-Blocker Withdrawal
The amlodipinecomponentofCADUETisnotabeta-blockerand thereforegivesno
protectionagainst the dangersofabruptbeta-blockerwithdrawal;anysuchwithdrawal
shouldbebygradual reduction ofthedoseofbeta-blocker.
Endocrine Function

Nodruginteraction studieshavebeenconductedwithCADUETandother drugs,although
studies havebeenconductedintheindividualamlodipineandatorvastatincomponents,as
described below:
Studies withAmlodipine:
Invitrodatain humanplasmaindicatethat amlodipinehasnoeffecton theproteinbinding
ofdrugstested(digoxin,phenytoin,warfarin,andindomethacin).
Cimetidine:Co-administrationofamlodipinewith cimetidinedidnotalterthe
pharmacokineticsofamlodipine.
Maalox®(antacid):Co-administrationofthe antacidMaalox witha singledoseof
amlodipinehadnosignificanteffectonthepharmacokineticsofamlodipine.
Sildenafil:Asingle 100mgdoseofsildenafil(Viagra®) insubjects withessential
hypertension hadno effectonthe pharmacokinetic parametersof amlodipine.When
amlodipineandsildenafilwere usedincombination,eachagent independentlyexertedits
own blood pressureloweringeffect.
Digoxin:Co-administrationof amlodipinewithdigoxin didnotchangeserumdigoxin
levelsordigoxin renalclearanceinnormal volunteers.
Ethanol(alcohol):Singleand multiple10mgdoses ofamlodipinehad nosignificant effect
onthe pharmacokineticsofethanol.
Warfarin:Co-administrationofamlodipine withwarfarindidnot change thewarfarin
prothrombinresponsetime.
Inclinicaltrials,amlodipine hasbeensafelyadministeredwiththiazidediuretics,
beta-blockers, angiotensin-converting enzymeinhibitors, long-actingnitrates,sublingual
nitroglycerin,digoxin, warfarin,non-steroidalanti-inflammatory drugs,antibiotics,and
oralhypoglycemicdrugs.

Studies withAtorvastatin:
The riskofmyopathyduringtreatment withHMG-CoA reductase inhibitor isincreased
withconcurrentadministrationofcyclosporine,fibric acid derivatives, lipid-modifying doses
of niacinor cytochromeP4503A4inhibitors(egerythromycin(seebelow)andazole
antifungals),(see alsosection 4.4Specialwarnings and precautions foruse:Skeletal
MuscleEffects).
Inhibitorsof cytochromeP4503A4
2 :AtorvastatinismetabolizedbycytochromeP450 3A4.
Concomitantadministration ofatorvastatinwithinhibitors of cytochromeP4503A4canlead to
increasesinplasmaconcentrationsofatorvastatin. The extentofinteraction andpotentiationof
effects depends onthevariabilityofeffectoncytochrome P450 3A4.
Transporter Inhibitors:Atorvastatinand atorvastatin-metabolitesare substratesofthe OATP1B1
transporter. Inhibitors oftheOATP1B1(e.g.cyclosporine)canincrease the bioavailabilityof
atorvastatin. Concomitantadministration ofatorvastatin10mgand cyclosporine5.2mg/kg/day
resultedin a7.7 foldincreaseinexposureto atorvastatin. (Seealsosection4.2Posologyand
methodofadministration-Use inCombination with OtherMedicinalCompounds)
Erythromycin/Clarithromycin:Co-administrationofatorvastatinanderythromycin
(500mgfourtimes daily),orclarithromycin (500mgtwicedaily)knowninhibitors of
cytochrome P4503A4,wasassociatedwithhigherplasmaconcentrationsofatorvastatin
(see WARNINGS, Skeletal Muscle ).
Proteaseinhibitors:Co-administrationofatorvastatinandprotease inhibitors,known
inhibitorsofcytochrome P4503A4,wasassociatedwithincreasedplasmaconcentrations
ofatorvastatin.
Diltiazem hydrochloride
2 : Co-administration ofatorvastatin (40mg)withdiltiazem
(240mg)wasassociatedwithhigherplasmaconcentrationsofatorvastatin.
Cimetidine:Anatorvastatininteraction studywithcimetidine wasconducted, and no
clinicallysignificantinteractions wereseen.
Itraconazole:Concomitantadministrationofatorvastatin(20to40mg)and itraconazole(200mg)
wasassociatedwith an increase in atorvastatinAUC.
Grapefruit juice:Containsoneor morecomponents thatinhibit CYP3A4andcanincreaseplasma
concentrationsofdrugsmetabolisedbyCYP3A4. Intakeofone240mlglassofgrapefruitjuice
resultedin anincrease in atorvastatinAUCof37%andadecreasedAUC of20.4%forthe active
orthohydroxymetabolite. However, large quantitiesofgrapefruitjuice(over 1.2Ldailyfor 5days)
increased AUCofatorvastatin 2.5fold andAUC of active (atorvastatinandmetabolites) HMG-
CoA reductaseinhibitors 1.3 fold. Concomitant intakeoflarge quantities ofgrapefruitjuiceand
atorvastatinistherefore not recommended.
Inducers ofcytochromeP4503A
2 :Concomitant administrationofatorvastatin withinducers of
cytochromeP4503A4(egefavirenz, rifampin) canleadtovariablereductionsinplasma
concentrationsofatorvastatin.Due tothedualinteractionmechanismofrifampin, (cytochrome
Caduet®Tablets,Israel, 29July2007
P4503A4 inductionand inhibition ofhepatocyte uptake transporter OATP1B1),simultaneous
coadministrationofatorvastatin with rifampinis recommended, asdelayed administration of
atorvastatinafter administrationofrifampin has been associated with asignificant reductionin
atorvastatinplasmaconcentrations.
Antacid:WhenatorvastatinandMaaloxTCsuspensionwerecoadministered, plasma
concentrationsofatorvastatindecreasedapproximately 35%.However,LDL-C reduction
was not altered.
Antipyrine:Because atorvastatindoes notaffectthepharmacokinetics ofantipyrine,
interactionswithotherdrugs metabolizedviathe same cytochromeisozymes arenot
expected.
Colestipol:Plasmaconcentrationsofatorvastatindecreasedapproximately 25% when
colestipolandatorvastatinwere coadministered.However,LDL-C reduction was greater
whenatorvastatinandcolestipol werecoadministeredthanwheneitherdrug was given
alone.
Digoxin:Whenmultipledosesofatorvastatin anddigoxinwere coadministered,steady-
stateplasmadigoxinconcentrationsincreasedbyapproximately20%.Patientstaking
digoxinshouldbe monitoredappropriately.
Azithromycin:Co– administrationofatorvastatin(10mgoncedaily) and azithromycin
(500mgoncedaily)didnot alter the plasmaconcentrationsofatorvastatin.
OralContraceptives:Coadministrationofatorvastatinand anoral contraceptiveincreased
AUCvaluesfornorethindroneandethinylestradiol byapproximately30%and 20%. These
increasesshouldbeconsideredwhenselectinganoralcontraceptivefora womantaking
CADUET.
Warfarin:Atorvastatinhadnoclinicallysignificanteffect onprothrombin timewhen
administered topatients receiving chronicwarfarin treatment.

DOSAGE ANDADMINISTRATION
Dosage ofCADUETmust be individualizedonthe basisofbotheffectivenessand
tolerancefor eachindividualcomponent in the treatmentofhypertension/angina and
hyperlipidemia.
Amlodipine(Hypertension or angina)
Adults:Theusual initialantihypertensiveoraldoseofamlodipineis 5 mgoncedailywith
amaximumdose of10mgoncedaily.Small, fragile,orelderly individuals,orpatients
withhepaticinsufficiencymaybe startedon2.5mgoncedailyand thisdosemaybeused
whenaddingamlodipinetoother antihypertensive therapy.
Dosageshouldbeadjustedaccordingtoeachpatient’s need. Ingeneral,titrationshould
proceedover7to14days sothatthephysiciancanfullyassess thepatient’sresponse to

characteristicssuchas goaloftherapyandresponse(seeNCEPGuidelines,summarizedin
Table8). Afterinitiationand/orupon titrationofatorvastatin,lipid levelsshouldbe
analyzedwithin2to4weeksanddosageadjusted accordingly.
Sincethe goal oftreatmentistolowerLDL-C,theNCEP recommendsthat LDL-C levels
beused to initiateand assesstreatment response. OnlyifLDL-Clevels arenotavailable,
should total-C beusedtomonitor therapy.
Heterozygous FamilialHypercholesterolemiain PediatricPatients (10-17 yearsofage)
The recommendedstartingdoseofatorvastatinis 10mg/day;themaximumrecommended
doseis 20mg/day(dosesgreater than20 mghavenot beenstudiedinthis patient

Concomitant Therapy
Atorvastatinmaybe usedincombinationwitha bileacidbindingresinfor additive effect.
The combinationofHMG-CoAreductaseinhibitorsandfibrates shouldgenerallybe
avoided (seeWARNINGS, SkeletalMuscle, andPRECAUTIONS, DrugInteractions
for other drug-druginteractions).
Dosage inPatients WithRenal Insufficiency
Renaldiseasedoesnot affecttheplasmaconcentrations norLDL-C reductionof
atorvastatin;thus, dosage adjustmentinpatients with renaldysfunctionis notnecessary
(seeCLINICALPHARMACOLOGY,Pharmacokinetics).
Use inCombinationwithOther MedicinalCompounds
Studies withatorvastatin:
Incases where co-administrationofatorvastatinwithcyclosporineis necessary,the dose of
atorvastatinshould notexceed10mg(seesection4.4Specialwarningsandprecautionsforuse–
