Chiesi in cystic fibrosis (CF)

Chiesi has been developing respiratory medicines for more than 30 years. CF is part of our Special Care business unit which also includes Neonatology and Transplantation. Chiesi are also expanding into medicines for other rare diseases.

Chiesi are committed to supporting CF specialists and their patients, in the UK and Ireland, through various CF initiatives, including a number of meetings and events for healthcare professionals each year.

A continually ageing CF population presents the challenge of needing more treatment options to help maintain good health for longer.1,2

At Chiesi, we are committed to tackling the continuing challenges of the management of CF, by providing medicines which aim to protect lung health, particularly through adulthood.

The Chiesi CF portfolio includes three inhaled treatments for people with CF; two inhaled antibiotics and a hyperosmotic mucolytic:

  • Quinsair® is an inhaled antibiotic licensed for the management of chronic pulmonary infections due to Pseudomonas aeruginosa in adult patients with cystic fibrosis.3
