Global biopharmaceutical company, Ipsen, is investing €15 million in its Blanchardstown site.
Tánaiste Leo Varadkar will launch the newly upgraded manufacturing facility today.
The company, which has been in Ireland for over 30 years, has a team of 175 employees.
General manager Tim Shanahan says they're working to produce life-enhancing care for patients with rare medical conditions.
"We are committed to supporting and building our dedicated team of 175 employees in Ireland.
"They'll be working across research and development, manufacturing and commercial operations."
The company has expanded its workforce at the facility by 20% since 2019 and grown its team of chemists and analysts by 10% over the past two years.
Mr Shanahan also says the recent investment of €52 million will support the acceleration of vital medicine production.
"That will upgrade and expand our manufacturing capabilities at our Dublin site.
"It will help Ipsen improve the quality of life for patients with niche and underserved medical conditions both in Ireland and international markets."
