GENERIC NAME: candesartan cilexetil
BRAND NAME: Atacand
DRUG CLASS AND MECHANISM: Candesartan cilexetil (candesartan) is in a class of drugs called angiotensin receptor blockers which includes losartan
(Cozaar), valsartan (Diovan), and irbesartan (Avapro).
Like these other drugs, candesartan blocks the ability of the chemical angiotensin II to raise the blood pressure by constricting or squeezing arteries and veins. This leads to a reduction in blood pressure. In addition, by reducing the pressure against which the heart must pump blood, candesartan reduces the work of the heart and is useful in patients with heart failure. The effects of angiotensin II also can be blocked by another class of drugs called angiotensin converting enzyme (ACE) inhibitors which prevent the formation of angiotensin II. ACE inhibitors include captopril
(Capoten), enalapril (Vasotec), benazepril (Lotensin), and lisinopril (Zestril).) Candesartan was approved by the FDA in 1998.
GENERIC AVAILABLE: no
PRESCRIPTION: yes
PREPARATIONS: Tablets, 4, 8, 16, and 32 mg.
STORAGE: Tablets should be stored at room temperature,
between 15 and 30°C (59-86°F).
PRESCRIBED FOR: Candesartan is used to treat high blood
pressure where it may be used alone or in
combination with other drugs. It has less of an effect in black patients, as do ACE
inhibitors. Candesartan also is approved for the treatment of patients with heart failure in whom it reduces the chances of death or hospitalization due to heart failure. Blockers appear to be approximately as effective as ACE inhibitors, and the effects of candesartan add to the effects of ACE inhibitors when they are used together.
DOSING: Candesartan usually is taken once daily.
DRUG INTERACTIONS: No important drug interactions have been
described with candesartan. Since ACE inhibitors and angiotensin receptor blockers both can increase the concentrations of potassium in the blood, other medications that can increase the concentration of potassium in the blood, such as hydrodiuril
(Dyazide), spironolactone (Aldactone),
and potassium supplements, should be used cautiously with candesartan.
PREGNANCY: When used in the second or third trimester of
pregnancy, ACE inhibitors can cause injury and even death to
the fetus. Therefore, candesartan--which has an action that is similar to the ACE inhibitors--should not be used during pregnancy. If pregnancy
occurs, candesartan should be stopped as soon as possible.
NURSING MOTHERS: Losartan (Cozaar) is secreted in rat milk, and
is toxic to newborn rats. Since candesartan is chemically similar to
losartan, it should be avoided in nursing mothers. It's safety and efficacy
in children have not been established.
SIDE EFFECTS: The most common side effect with candesartan is
dizziness which occurs in 1 out of every 25 persons).
