candesartan (Atacand)
Tradname: Atacand. (candesartan cilexetil) Generic Dec 2012 [8]
Indications:
- an ACE inhibitor is indicated, but not tolerated
a) hypertension
b) heart failure (see CHARM trials)
c) diabetes mellitus*
- diabetic nephropathy
d) nondiabetic proteinuric nephropathy [8]
e) stroke prevention [2]
f) migraine prophylaxis [4,10]
g) may improve executive function# after 1 year in elderly independent of antihypertensive effect [9]
* Only irbesartan (Avapro) & losartan (Cozaar) shown to have beneficial effects [3]; candesartan probably does as well
# measured by Trail Making Test Part B [9]
Contraindications:
1) pregnancy, trimesters 2 & 3, probably 1 as well
2) angioedema with ACE inhibitor
Dosage:
- start: 16 mg QD when used as monotherapy
- CHF: start 4-8 mg QD; max 32 mg QD
Tabs: 4, 8, 16, 32 mg.
Addition of 12.5 mg of HCTZ may improve BP response.
Dosage adjustment in renal failure:
- No dose adjustment is required for elderly or patients with mild renal insufficiency or hepatic insufficiency
Pharmacokinetics:
- bioavailability 15%, enhanced by foot
- onset of action 2-3 hours
- peak effect 6-8 hours
- 1/life 9 hours (dose-dependent)
- volume of distribution 0.13 L/kg
- protein binding 99%
- clearance 60% renal, 36% biliary
Adverse effects:
- cardiovascular: flushing, chest pain, peripheral edema, tachycardia, palpitations
- no increased risk of myocardial infarction in high-risk patients [5]
- CNS: dizziness, lightheadedness, drowsiness, fatigue, headache, vertigo, anxiety, depression, somnolence, fever
- dermatologic: rash, angioedema (occurs within 30 minutes-30 days of 1st dose)
- metabolic: hyperglycemia, hypertriglyceridemia, hyperuricemia small increases in serum K+ as with ACE inhibitors
- gastrointestinal: nausea, vomiting, diarrhea, dyspepsia, gastroenteritis
- musculoskeletal: back pain, arthralgia, increased CPK, myalgia weakness
- neurologic: paresthesia
- renal: hematuria
- respiratory: upper respiratory tract infection, pharyngitis, rhinitis, bronchitis, cough, sinusitis, epistaxis, dyspnea
- diaphoresis [6]
Mechanism of action:
1) angiotensin II receptor antagonist
2) BP reduction of 8-12/4-8 mm of Hg with 8-32 mg QD
3) limited effectiveness for diabetic retinopathy [7]
a) diabetes type 1:
- modest reduction in the incidence of retinopathy
- was no effect on progression of retinopathy.
b) diabetes type 2
- may risk for progression of retinopathy
- may facilitate regression of early retinopathy
