Are you a

Healthcare professional?

Do you work with patients or clients with swallowing problems? Is the intake of medication often a battle? Do you have to come up with all kinds of tricks to get the medication administered?

Since a couple of years Gloup is on the market. It is a registered medical device that helps many people with taking their medication in a safe way. Of course we understand that you as a healthcare professional want to have more information and data showing you the safety of a product like Gloup. Our products are all based on clinical and scientific data about medication administration, safety and interactions.

In your current practice

Try to avoid

The use of fruit juices/apple sauce for the administration of medication:

  • Fibers have a negative impact on a number of medication [3,4,5,6].
  • Bioflavonoïds in fruit have a negative impact on certain medication [7].
In your current practice

Try to avoid

The use of dairy products for medication administration:

  • Decreases the effect of lots of different medication [8] .
  • Decreases the absorption of specific medication [9].
In your current practice

Try to avoid

Crushing medication/opening capsules:

  • Can decrease effectiveness and stability of medication and increase toxicity [10].
  • Increased risk of health issues for healthcare professionals because of increased toxic effects via inhalation and skin exposure. [10].
In your current practice

Try to avoid

The use of food thickeners for the intake of medication:

  •  Decreases the absorption of different medication dramatically [14].
  • Xanthan Gum and gom en Guar Gum have a huge impact on the absorption of medication [15].

Gloup: the safe choice

  • Registered Medical Device Class 1
  • Patented formulation
  • Use of Gloup: 48% ease of use, 34% decrease crushing and 33% increased therapy loyalty [13].
  • Studied in multiple ways by The University of Queensland (UQ)/ School of Pharmacy Brisbane/Australië [11, 12, 13].
  • Use of food thickeners: Decreases absorption of different medication dramatically [14].
  • Xanthan Gum en Guar Gum have huge impact on absorption of medication [15].
  • Queensland University classifies Gloup Original and Zero as IDDSI level 3 (room temperature) and Level 4 (from fridge) [12].
  • Queensland University classifies Gloup Forte as only genuine IDDSI Level 4 swallowing aid available.
  • Decreases the need to crush up to 40% [11].


Because food has not been developed for the intake of medication, it is not the best choice. Gloup has been specifically designed for the intake of medication and is a medical device. It is helping people that face problems with swallowing oral medication. Gloup is a gel that covers the pill and makes the pill slide down the throat easily. Gloup masks the bitter taste of the medication and does not effect the effectiveness of the medication administered. It is a registered medical device class 1, designed and improved in collaboration with different universities around the world.

How to use Gloup

  • 1. Let the patient try Gloup first without any medication;
  • 2. Start with just 1 tablet and expand to multiple tablets per intake later;
  • 3. Put the tablet(s) on a spoon;
  • 4. Put Gloup on top so the medication is fully covered (not too much);
  • 5. Offer the spoon to the patient for intake;
  • 6. After the intake with Gloup a glass of water can be taken but that is not necessary;
  • 7. Gloup Forte: First put some Gloup on a spoon, than add the tablet and put some Gloup on top;
  • 8. Gloup can be used with both entire and crushed tablets. Always check at the pharmacy whether the medication is allowed to be crushed;
  • 9. Crushed medication: First put some Gloup in a medicine cup, than add the crushed medication and put some Gloup on top. Finally spoon it up entirely and offer it to the patient;
  • 10. It might happen that the administration of medication with Gloup is not successful the first time. Please keep in mind that he/she has to get used to the texture of the gel, because this is the first time he/she swallows medication with a gel. Try multiple times and it will definitely improve;
  • 11. Because Gloup is slippery, there is a huge chance that less crushing is necessary as Gloup eases swallowing the entire tablet. It is always best practice not to crush if not needed!
