Omnicare Inc. announced it will trade its home infusion business to Walgreen Co. In exchange, Omnicare will acquire the drugstore chain’s long-term care pharmacy business. Omnicare’s Interim President and CEO James D. Shelton said the exchange allows his firm to “redeploy our resources towards a growth opportunity that better leverages our core competencies and further expands our presence in the growing senior care market.” While financial terms were not disclosed, the deal is expected to conclude before Nov. 15.
