## Abstract

Growth and development
of the pharmaceutical sector in Ireland
has been remarkable over a 50 year period starting as an API manufacturing
hub with strong regulatory confidence gradually expanding to include
a range of activities ranging from process R&D, formulation services,
and other high-value elements of the pharmaceutical enterprise, while
in parallel complementary expertise in bioprocessing and biotechnology
has resulted in the sector being globally significant and integrated
into global supply chains. The more significant change in API manufacture
in recent years has been the introduction of continuous flow technology
offering many advantages including safety, efficiency, and flexibility.
Nevertheless, in such a highly regulated sector navigating the transformation
from traditional large-scale batch manufacture to embedding flow technology
is not trivial. The Irish landscape, comprising leading multinational
API-producing sites, complemented by Contract Development and Manufacturing
Organizations (CDMOs) and indigenous companies providing tailored
services, has very successfully embraced embedding continuous flow
technology for API and RSM manufacture at scale in partnership with
the regulatory agencies. In this context, some aspects underpinning
this transition are discussed as an informative commentary on the
state-of-the-art for the use of flow in API/RSM manufacture.
