BEDMINSTER, N.J.--(BUSINESS WIRE)--Results from the CLUE study, a head-to-head comparison between Ready-to-Use Cardene® I.V. (nicardipine) and labetalol in the emergency room, showed that Ready-to-Use Cardene I.V. lowers acutely elevated blood pressure more effectively than labetalol. These data were presented today at the annual meeting of the American College of Emergency Physicians (ACEP) in Las Vegas, Nevada.
