- the pharmaceutical dosage form is a colorless liquid
- the pharmaceutical dosage form can be replaced, for example, by a physiological sodium chloride solution.
- an opaque application system can be used for administration. It is understood that these methods are not suitable for intrapulmonary administration.
- the double blind technique double observer technique
- the object of the present invention is to provide a device which enables the administration of non-solid pharmaceutical dosage forms to be blinded in clinical trials in a simple manner and without using the double-blind technique.
- the invention therefore relates to a device for blinding the administration of non-solid pharmaceutical dosage forms during clinical trials on mammals.
- the device is an opaque container that has at least two ports, one of which is suitable for connection to a delivery device for the pharmaceutical dosage form and the other for connection to one Application agent is suitable and the container has in its interior means for retaining the pharmaceutical dosage form (hereinafter also referred to as "non flow type" configuration).
- the invention relates to an opaque container which has at least two connections, one of which is suitable for connection to a dispensing agent for the pharmaceutical dosage form and the other is suitable for connection to an application agent, and the connections inside the Containers have a continuous connection that ensures transport of the pharmaceutical dosage form through the container (hereinafter also referred to as "flow type" configuration).
- the pharmaceutical dosage form - which is not recognizable to the person responsible for the administration - is transported through the container and administered to the patient.
- the invention relates to a container which can enable both the transport of the pharmaceutical dosage form through the container and the retention of the pharmaceutical dosage form in the same container.
- the invention therefore furthermore relates to an opaque container which has at least three connections, two of which are suitable for connection to a dispensing agent for the pharmaceutical dosage form and the third is suitable for connection to an application agent, the inside of the container being used for Retention of the pharmaceutical dosage form and one of the connections which are suitable for the connection with a delivery means inside the container has a continuous connection with the connection which is suitable for the connection with the application means and the connection ensures a transport of the pharmaceutical administration form through the container .

- Preferred are containers which have an internal volume of 500 ml to 3000 ml, particularly preferably those which have an internal volume of 1000 ml to 2000 ml.
- the container should preferably have a correspondingly higher weight. This makes it difficult or impossible to compare the weight of the container before and after application of the test substance by the person entrusted with the administration of the substance. In this respect, containers with a dead weight of more than 1 kg have generally proven to be advantageous.
- the container can have weight elements on the inside in order to ensure a sufficient weight of the container.
- the weight elements can be hard rubber disks, for example.

- the connections for differentiation preferably have different markings.
- the dispensing means is preferably a commercially available syringe which can be connected directly or via a hose connection to the connection provided on the container.
- the application agent is preferably an opaque application agent, for example an opaque catheter system, preferably a catheter system that is suitable for intrapulmonary application of a non-solid pharmaceutical dosage form. Such catheter systems are known to the person skilled in the art.
- the container according to the invention which causes the pharmaceutical dosage form to be retained, can furthermore be connected at the connection which is intended for connection to the delivery means by means of a hose which leads into the interior of the container and has an open end through which the pharmaceutical Dosage form is released into the interior of the container.
- the hose advantageously has a plurality of openings in the hose line. This ensures rapid delivery of the pharmaceutical dosage form into the interior of the container.
- the hose can advantageously also have a non-return valve which prevents the pharmaceutical dosage form dispensed into the interior of the container from flowing back into the hose.
- the connection provided for the connection with the application means can be provided in the interior of the container. NEN closure, so that leakage of the retained pharmaceutical dosage form in the application agent is excluded.
- this can be a closed hose leading into the interior of the container.
- the two hoses leading into the interior of the container can be connected to one another via a Y-connecting piece, the hose leading to the connection provided for the application means being tightly sealed or sealed by a pinch or weld .
- the 3rd connection of the Y-connector has an open cap, through which the supplied pharmaceutical dosage form can flow into the blister.
- the container according to the invention which causes the pharmaceutical dosage form to be transported through the container, advantageously has a continuous hose connection between the connections inside the container.
- the container can be hollow or, if desired, can also be filled with suitable materials, such as absorbent materials and weight elements.
- the container is preferably designed in accordance with the container which causes the pharmaceutical dosage form to be retained in the container.
- the container according to the invention can furthermore have a venting device (e.g. valve) in order to compensate for pressure differences which result from the retention of the pharmaceutical dosage form in the container.
- a venting device e.g. valve
- the containers according to the invention are advantageously suitable for blinding the administration of non-solid, in particular liquid administration forms by intrapulmonary application.
- Pharmaceutical dosage forms that have the properties of natural pulmonary surfactant may be mentioned as a liquid dosage form.
- the dosage forms described in W095 / 32992 may be mentioned as examples.
- the different containers are preferably designed in such a way that a differentiation by the person is not possible.
- Fig. 1 is a schematic cross-sectional view of an embodiment of an opaque container according to the invention which retains the pharmaceutical dosage form in the container.
- Fig. 2 is a schematic cross-sectional view of an embodiment of an opaque container according to the invention, which ensures the transport of the test substance through the container.
