In pharmaceutical manufacturing plants there is always the doubt related to when it is necessary to have a dedicated facility or when it is possible to manufacture in a same area different products specially when some of them are steroids, sexual hormones, corticoids, cytostatics, high potency, prostaglandins, \u2026<\/p>\n
This lack of definition is understood in different ways for pharmaceutical companies, regulatory agencies, consultants which makes major uncertainty when making the decision about whether it is needed a dedicated facility or not for certain products.<\/p>\n
This uncertainty has a tremendous impact on the investments to be made by a pharmaceutical company as well as in the commercial opportunities developing and manufacturing certain products.<\/p>\n
The specific points of the most relevant regulations (EMA, FDA, ICH, WHO and PICs) with regard to compatible products in the manufacturing lines, and to the need to either have or not have dedicated facilities are gathered in the following list<\/p>\n

If after those calculations any of the criteria still don\u2019t meet the limits, dedicated facilities would be required.<\/p>\n3. LACK OF DEFINITION<\/strong><\/h2>\n
