The provision of drug therapy by a healthcare professional (HCP) to a patient is a complex process. Medication errors can occur at any step along the pathway including dose miscalculation. Thus, we have developed a web and mobile application for HCPs that will help them calculate the appropriate dose of a drug based on the drug’s SmPC. To note, this application comply with all legal requirements. We have developed applications for Merck (fertility calculator), Novo Nordisk (hemophilia dosage calculator) and many others. All HCPs have claimed that these applications have simplified the drug prescription process.
