U.S. pharmacy benefit manager Express Scripts Inc (ESRX.O) is expressing more caution about any international expansion, its CEO said on Monday, even as its main rival strikes deals overseas. The company sees opportunities internationally, but is not "overly excited" about Europe, Express Scripts Chief Executive Officer George Paz told the JP Morgan healthcare conference in San Francisco. Rival Medco Health Solutions Inc (MHS.N) is making inroads in Europe, where it sees an opportunity to employ tools used by pharmacy benefit managers to hold down medicine costs and improve quality.
