Consumer:

Atazanavir may prolong the PR interval of the electrocardiogram in some patients. In one study, the mean maximum change in PR interval from baseline was 24 msec following a 400 mg oral dose of atazanavir versus 13 msec following placebo dosing. In studies of healthy volunteers and HIV patients, abnormalities in atrioventricular (AV) conduction were asymptomatic and limited to first-degree AV block. Rarely, second-degree AV block and other conduction abnormalities have occurred in overdose. Due to limited clinical experience, therapy with atazanavir should be administered cautiously in patients with preexisting conduction abnormalities (e.g., marked first-degree AV block or second- or third-degree AV block).
