The company MedLight specialises in the design and creation of new apps, particularly for use in the healthcare sector. MedLight is responsible for the distribution and marketing of the Orthodose® app.

The Orthodose® initiative was born in 2010 out of the need for palliative care practitioners to simplify the calculation of opioid rescue doses. Developed by a doctor specialising in palliative care with more than 20 years experience, Orthodose® has proven to be an innovative and effective medical app.

Our platform contains the latest information on medical prescriptions in palliative care, and makes all this information easy to access.


Behind Orthodose®

Vincent Vandenhaute MD, a doctor specialised in pain management and palliative care, and a teacher and trainer in the palliative care field, created Orthodose® to fill a gap and meet a new need emerging in our practice.


A little history

We created our first software program in 2010. The initiative for this project arose from our desire to offer both general and specialist practitioners a reliable and easy-to-use tool to calculate opioid rescue doses. Available to general practitioners free of charge, the windows app format was chosen to meet the needs of doctors.

We decided to call the product Orthodose®. The name makes reference to ORTHO, which comes from the ancient Greek ὀρθός, Ortho (“right”), used here as a prefix to express the concept of accuracy and precision.

From the outset, Orthodose® was intended to support general practitioners and specialists by offering them a reliable and user-friendly tool to calculate rescue doses of morphine and to facilitate effective management of pain and breakthrough pain.
It was quickly supplemented by various tools, all intended to contribute to the delivery of the most appropriate palliative care.

In 2013, the first Orthodose® mobile app was made available free of charge from the Apple and Android stores.



Orthodose® is a reliable and transparent medical mobile app, whose use is growing rapidly and which today supports doctors at the very heart of their daily palliative care practice.

Numerous messages of encouragement have motivated us both to broaden its scope of application, and to perfect its design, making this more intuitive, more understandable and customisable according to your taste.

The new tools offered include, briefly, the following:
– benzodiazepine conversion, particularly useful when it is not possible to take these orally, and an IV or SC route is needed;
– the US FDA recommendations regarding opioid intoxication;
– the choice of drug mixtures that are possible in pumps;
– drugs that can be administered via the SC route;
Work is also underway to produce some explanatory and illustrative videos as well as setting up a blog.

As you can see, we want to make Orthodose® sustainable and to enrich it with new tools. To achieve this, Orthodose® now needs to apply a charge. Palliative care is developing and diversifying, new stakeholders, such as the many home-based caregivers, are fully involved in this care. Palliative care education is developing, as are medical IT tools. These changes require more major updates and maintenance.

No matter how successful we become, we will stay true to our ethics and core values.

Despite the necessary shift to subscription-based use, we remain fiercely true to our ethics, to our original fundamental values and our creative freedom. Your necessary support encourages us in this and for this we thank you.

Four core values


Rescue Dose is currently the only mobile application on the market that allows the calculation of rescue doses and the only one to incorporate conversion ratios derived from Evidence-Based Medicine.

It is further currently supplemented by two major new applications, which represent a world first:
Mix&Match and Benzo Switcher


Used for more than 10 years, this medical app was designed specifically for palliative care professionals.

Easy to use

Whether in the patient’s home, in your surgery, or in hospital, you can access Orthodose® applications everywhere via your smartphone, even at your patient’s bedside.


The Orthodose® app is independent of the pharmaceutical industry and is not influenced by lobbies. From its launch up until 2022, the app was free, however, faced with continuous technological development, we have finally been obliged to charge for access to part of the app. Orthodose® is free from cumbersome adverts.
