Definitions
- Single-dose active substance preparations are understood to mean preparations which contain a predetermined amount of active substance in divided and individually manageable units of the preparation.
- an active ingredient in the sense of this invention e.g. a drug, an insecticide, a pesticide, a reagent, etc. can be understood.
- an active substance is understood to mean a medicinally active substance
- such single-dose pharmaceutical forms are, for example, tablets, capsules, suppositories or transdermal therapeutic systems (TTS).
- Non-dosed dosage forms would be e.g. Sprays, juices, ointments and drops, in which the actual dosage is made just before use.
- the active ingredient is to be processed in a measured amount together with any necessary auxiliary substances to form the active ingredient preparations ready for use.
- This technique can be considered mature in the manufacture of tablets and capsules. Modern tablet presses and capsule filling machines guarantee high production speeds and very precise dosing in a range of 95-105% of the target value.
- Transdermal therapeutic systems are still a relatively young drug form, which is applied externally in the form of a patch on the skin and releases the active ingredient through the skin to the organism.
- TTS Transdermal therapeutic systems
- the active ingredient is contained directly in the adhesive and is metered in the form of a sheet onto a film together with the adhesive.
- TTS the only pharmaceutical form that depends on dosing a medicinal active ingredient in a predetermined amount on a specified surface. If you think of non-medical active ingredients, e.g. Insecticides, pesticides or reagents, surface preparations in the form of impregnated papers, foils or boxes have been known for some time. However, for these applications, the accuracy of the metering in the area is not particularly demanding.
- non-medical active ingredients e.g. Insecticides, pesticides or reagents
- surface preparations in the form of impregnated papers, foils or boxes have been known for some time. However, for these applications, the accuracy of the metering in the area is not particularly demanding.
- the present invention has for its object to provide a method for metering powdered active ingredients on a given surface.
- the dry copy process or xerography works in the manner described below.
- a roller coated with a photoconductive material is provided with a positive electrical charge and exposed to the original to be copied via suitable optics. Through this process, the charge is at least partially removed where the conductivity of the photoconductive material increases due to the exposure.
- negatively charged color particles toner are applied to the roller, which, however, only adhere to the still charged areas of the roller in an amount dependent on the size of the load and create a visible image there.
- the color particles (toner) are then transferred to a positively charged paper or film and fixed there by heat treatment.
- a modern variant of the process is used in the so-called laser printers.
- the roller is directly exposed to a laser beam without a template and the image is thus computer-controlled written directly on the roller. Otherwise, the same technology is used for laser printers as for dry copiers.
- the present invention is based on the use of these processes in order to transfer active substance particles onto paper or generally foils instead of the color pigments.
- the film used is a large commercial polyester film in A4 format.
- a deep black sheet of paper was used as the template and the heaviest degree of blackening was selected for the copy. The results are shown in the following table.
- the amount transferred in a copying process is small, but this disadvantage can be overcome by copying several times without the accuracy of the dosage being impaired.
- the amount of toner or active ingredient transferred depends on the charge state of the copying roller and can be increased by a higher charge than is usual in copiers.
- the exposure cut can be dispensed with entirely.
- the copying roller need not be made of a photoconductive material.
- the exposure cut and the use of a photo-conductive material e.g. Selenium, coated KopierwalZ ⁇ necessary.
- the exposure can take place using a template or else computer-controlled using a laser. The greatest variability is of course with the computer-controlled laser exposure.
- the flat substrate to which the active substance is transferred can in principle consist of any materials, as long as it is flexible and suitable to survive the fixing process. It is conceivable that the material is used in the form of sheets or comes from a roll. This material is then cut into smaller parts in the course of further processing and thus transferred to the individually dosed active ingredient preparation. Alternatively, the material can also be perforated, in which case the dosage is predetermined by the perforation.
