Overview
Pulmicort Flexhaler, an inhalation corticosteroid medication primarily used for the management of asthma and chronic obstructive pulmonary disease (COPD), has become a staple in respiratory therapy. Manufactured and distributed by AstraZeneca, Pulmicort Flexhaler’s supply chain depends on a sophisticated network of raw material producers, formulation specialists, contract manufacturers, and global distribution partners. This article details the key suppliers involved in the production of Pulmicort Flexhaler, highlighting the roles of raw material providers, manufacturing entities, and distribution networks critical to this pharmaceutical’s availability.
Raw Material Suppliers
The primary ingredients of Pulmicort Flexhaler include active pharmaceutical ingredients (API) such as budesonide, along with excipients and device components. Each element's quality directly impacts drug efficacy and safety, creating a stringent supply chain for these raw materials.
Active Pharmaceutical Ingredient: Budesonide
Budesonide is a potent glucocorticoid with anti-inflammatory properties. Its procurement involves multiple global suppliers specializing in steroid synthesis.
- Key Suppliers
- Hovione: A global API supplier offering high-quality steroid APIs, including budesonide, with manufacturing facilities in Portugal. Hovione adheres to cGMP standards, ensuring supply reliability.
- Sterling Pharma Solutions: Based in the UK, Sterling supplies API intermediates and finished APIs, including steroid compounds like budesonide, meeting stringent regulatory standards.
- Zhejiang Xianju Pharmaceutical Co., Ltd.: A significant Chinese API producer providing competitively priced budesonide, increasingly integrated into global supply chains due to quality compliance and export licensing.
Excipients and Device Components
Excipients include carriers and stabilizers that facilitate drug delivery. Suppliers like DuPont and BASF provide pharmaceutical-grade polymers and excipients conforming to pharmacopeial standards.
The device components—primarily inhalation chambers, valves, and casing—are supplied by specialized companies such as Gerresheimer and Ypsomed, which manufacture device parts to medical device regulations.
Formulation and Manufacturing
AstraZeneca partners with Contract Manufacturing Organizations (CMOs) for the formulation, assembly, and packaging of Pulmicort Flexhaler. These CMOs ensure compliance with global regulatory standards and supply readiness.
Primary Contract Manufacturers
-
Catalent Pharma Solutions
Catalent, a leading CMO with facilities in Europe and North America, handles as much as 80% of the formulation and assembly processes for Pulmicort Flexhaler. Their capabilities include inhaler device assembly, formulation, and sterilization.
-
Almac Group
Based in the UK, Almac specializes in sterile manufacturing and formulation development, contributing to quality assurance and regulatory compliance.
-
Recipharm
