In general, candesartan (the active ingredient contained in Atacand) has been well tolerated in large, prospective, placebo-controlled clinical trials. Overall, the rates of withdrawal of therapy due to adverse events among treated versus placebo patients were 3.3% and 3.5%, respectively.
Nervous system side effects have been reported the most frequently. These have included headache (3%) and dizziness. Fatigue, vertigo, and paresthesias have been reported in at least 0.5% of patients.
Cardiovascular side effects including peripheral edema and chest pain have been reported in 1% of patients and at rates similar to placebo. Myocardial infarction and angina pectoris have been reported rarely. Hypotension (18.8% vs. 9.8% in placebo), tachycardia (0.5%), and palpitations (0.5%) have been reported. Rare cases of angioedema have also been reported.
Caution should be observed when initiating therapy in patients with heart failure. Patients with heart failure given candesartan commonly have some reduction in blood pressure. In the CHARM program, the incidence of hypotension leading to drug discontinuation in candesartan-treated patients was 4.1% compared with 2.0% in placebo-treated patients.
Respiratory side effects have included cough, but it has been less frequent with the use of candesartan (the active ingredient contained in Atacand) or other angiotensin II antagonists (reported in approximately 1% of treated patients and placebo patients alike) than with angiotensin converting enzyme inhibitors. Bronchitis, coughing, sinusitis, pharyngitis, upper respiratory tract infection, and dyspnea have been reported in approximately 0.5% to 1.0% of patients. Upper respiratory tract infections have been reported among 6% of treated patients (compared with 4% placebo patients) in controlled clinical trials. These infections have included pharyngitis (2% vs. 1% of patients) and rhinitis (2% vs. 1% of patients). A cause-and-effect relationship is unlikely.
