Merck Serono, a Division of Merck KGaA, Successfully Rolls Out PAS-X MES in Mexico

Lueneburg, Germany - Merck Serono and Werum Software & Systems have jointly implemented PAS-X, Werum's Manufacturing Execution System (MES) for the manufacturing of solids and liquids at Merck Serono's pharmaceutical plant in Mexico. This takes the company one step further in rolling out PAS-X as the standard MES system for its global pharmaceutical operations.

The new PAS-X MES at the Naucalpan plant (near Mexico City) replaces the former paper-based production control procedures with an electronically- based process. A new weighing system replaces the current weighing system. It was also one of Merck Serono's main priorities to interface the MES with the company's global SAP ERP system.

The functions of the new PAS-X MES cover the entire manufacturing process, from weighing & dispensing, tabletting and filling of liquids right through to packaging. Merck Serono Mexico expects an increase in efficiency similar to that experienced with the introduction of PAS-X in Darmstadt, Germany, in 2008. Electronic Batch Records based on electronic "review by exception" effect significant time savings and a considerable improvement in quality ("right first time").
