Pfizer CentreOne has been a leading provider of specialty APIs for more than 50 years. We bring quality, integrity, technical expertise and supply assurance, and seek to continuously improve your products. We manufacture a specific segment of complex compounds: cortico- and hormonal steroids, prostaglandins, and antibiotics. But if you need scale-up and manufacture of your proprietary molecule instead, custom API contract manufacturing is also one of our core competencies.
