Actavis PLC said Monday that its revenue rose a better-than-expected 60% in the first quarter that included the acquisition of Botox maker Allergan Inc. Dublin-based Actavis completed its acquisition of Allergan in March, closing the biggest deal from 2014 and ending one of the year's more dramatic takeover battles. The deal made Actavis one of the world's largest drug makers by sales, offering a range of eye, skin and stomach drugs.
