A different perspective on data: redefining pharmaceutical care

Welcome to Medstone

Medstone - A PharmTech Company

Medstone PharmTech

Medstone is dedicated to optimising pharmaceutical care. We believe in the power of data to support pharmacists in their everyday job. Advising the best possible treatment for each patient and optimising the logistical processes, resulting in a long term sustainable business.

Stone Algorithm

Our team consists of pharmacists, data scientists, software developers and research associates. This unique combination of people allows us to apply pharmaceutical knowledge with cutting-edge machine learning. Our content guides pharmacists and other healthcare professionals in their quest for the best pharmaceutical products for their patients.

Medstone System

Medstone offers a fully digitalised platform for pharmacists. Our platform provides pharmacists a clear overview of relevant pharmaceutical products, which they can share with their team and other healthcare colleagues.

Pharmaceutical Landscape Today

In recent years the amount of new first-in-class drugs has declined, while the total number of submissions has remained stable. As a result physicians have more treatment alternatives for the same indication. Each new treatment alternative is accompanied with large amounts of (scientific) product information. This challenges health care professionals in knowing all differences and which treatment is best for their patients.

The branded products (both first in class and alternatives) are pivotal for the pharmaceutical industry. They represent the majority of total drug costs in a retail pharmacy, while the volume dispensed is only 25%. This increases the importance of choosing the right branded product.

Stone - The Medstone Algorithm

Stone Algorithm

Stone is based on published data and uses AI

Our algorithm gets input and systematicaly searches for published data. Each matching publication is stored in our database. Articles will be analyzed for the parameters on which to compare the products.

Smart Linguistic Software

Smart linguistic software - the real complexity of Stone

Stone is able to read complex scientific data from our database autonomously. It processes the words and presents the relevant information. Daily our pharmacists and research associates carefully train Stone to make it more intelligent.
