Medicinal product service from regulatory affairs and Rx OTC switches to GMP audits

Diapharm supports clients in developing, manufacturing and marketing medicinal products, in ensuring medicinal product safety across the entire life cycle – and in achieving economic success.

We develop products with added value and create legally viable strategies – for both OTC and prescription-only medicinal products. Our teams of specialists for medical and regulatory affairs, pharmacovigilance and pharmaceutical quality management prepare CTD dossiers, look after marketing authorisations, assist with Rx/OTC switches and guarantee pharmacovigilance. We audit and evaluate quality management systems and perform GMP audits.

We also take over legally prescribed roles of responsibility and act as qualified person for pharmacovigilance (24/7), information officer, qualified person or marketing authorisation holder for our clients.
