Definitions
- the present invention relates to a process for the production of flowable, press-ready pharmaceutical precursors for the manufacture of tablets, dragee pellets and pellets from plant drugs, which precursors can be used for tableting without further intermediate stages, and the pharmaceutical precursors as such.
- it relates to a method which avoids the disadvantages of conventional wet granulation without having to resort to direct tableting.
- direct tableting the second method known from the prior art for producing tablets from dried plant drugs, the individual constituents of the tablets, that is to say drug material and carriers or auxiliaries, Form suitable for direct tableting, for example in the form of granules, and are mixed with one another in a complex manner in this form. Since some of the finished tablets can contain up to 20 different substances in addition to the medicinally active ingredients, each of which requires introduction at a precisely defined point in the production process so that the newly added ingredients remain stable in the granulate, direct tableting is a relatively complex process The granulation process is therefore a lengthy, costly process in the pharmaceutical industry, which undesirably ties up time, energy and technical personnel.
- the object of the invention is achieved by a process for the production of a flowable, press-ready intermediate product, in which dried plant drug material is moistened together with the desired additives, carriers and / or auxiliaries in a vacuum drying system which extends through a cylindrical mixing and drying chamber 'Mehrschenkliges.,' agitator with its own drive, the system being provided with a filter, a backwashing device, a solvent condenser with aftercooler and collecting vessel, a back condenser and / or a process, control and regulating unit, if necessary, and the moist mixture at a jacket temperature of the device of 20 ° C to 50 ° C, preferably 20 ° C to 40 ° C and most preferably 30 ° C, a product temperature between 20 ° C and 40 ° C, preferably 20 ° C and 30 ° C and most preferably 20 ° C to 25 ° C and a pressure of 20 to 500 mbar, preferably 50 to 2 00 mbar and most preferably 50 to 100
- the process of the invention ver ⁇ are reversible are, for example, the ITU-T ® INOX -Universaltrockner, for example, the types of ITU-T 20 50 ITU-T, ITU-T 100 or ITU-T 2.000.
- the desired constituents of the finished tablet or pharmaceutical preparation can be fed into the process simultaneously or in succession.
- the moistening is preferably carried out by adding water or a water / solvent mixture in an amount of from 0.01 to 0.05 ml / g, preferably from 0.02 to 0.04 ml / g of solids.
- Lower alcohols such as methanol, ethanol, propanol or glycol and glycerol, ketones such as acetone or ethers such as diethyl ether, glyme, diglyme can preferably be used as solvents.
- Water or water / alcohol mixtures are preferably used.
- highly disperse silicon dioxide is preferably added within the limits of 1 to 10%, based on the total mass, preferably between 3 and 6%.
- the drying time is again possible to reduce the drying time to values between 30 minutes and 2 hours, preferably 1 to 1.5 hours. Since, in addition to the shortened drying time, which leads to considerably reduced bacterial counts, the drying temperature can be reduced and the air supply can be reduced, the flowable, ready-to-press precursors according to the invention have a higher content of active pharmaceutical ingredients in comparison to moist granules produced by conventional methods. This is because the undesirable effects of air drying can be eliminated.
- the method according to the invention also has the advantage that the time for the production of granules is considerably shortened, the production is considerably simplified and can be carried out with fewer personnel.
- Fig. 1 shows a time comparison between classic wet granulation, fluidized bed granulation and vacuum granulation according to the invention, as well as direct tableting. It can be seen from the illustration that the method according to the invention looks at the time advantage is comparable to direct tableting. This is, however, ⁇ uplifting Lich process more complex and provides significantly greater demands on the purity and physical nature of the employed raw materials. Overall, the method according to the invention therefore offers advantages over all methods of the prior art.
- usable dry plant material can be of each desired plant to Materi al ⁇ from flowers, roots, rhizomes, tubers, leaves or other plant parts.
- drugs here are, for example, types of Althaea, Juglans, Millefolium, Cen-aurium, Rosmarinum, Gentiana, Primula, Rumex, Sambuco , Echinacea, Phyllanthus and Verbena as well as Agnus Castus, Allium, especially Allium cepa, Hedera helix, Hippocastanus, Curcuma, Galphimia, in particular Galphimia glauca, Herba Thymii or mixtures thereof.
- Flos Sambuci Flos Primulae, Herba Rumicis, Radix Gentianae, Herba Verbenae or mixtures thereof, for example, the forte for producing Sinupret ® or Sinupret® dragees mixtures used.
- Carriers, additives and auxiliaries to be used according to the invention are the additives, carriers and auxiliaries conventionally used for tableting.
- starch and starch derivatives, silicon dioxide, lactose, lactose monohydrate, cellulose and cellulose derivatives, magnesium stearate, calcium stearate, calcium hydrogen phosphate, PVP or povidone, polyethylene glycol or macrogol, mannitol, sorbitol, gelatin, sugar alcohols, stearic acid and their saline and their salts are to be mentioned here Mixtures of the same. Silicon dioxide alone or in a mixture with one or more of the substances mentioned is preferred.
- acrylic derivatives alginic acid, alpha-octadecyl-omega-hydroxypoly- (oxyethylene) -5-sorbic acid-H 2 O, arabic gum, aromatic substances, ascorbic acid, calcium carbonate, calcium hydrogen phosphate, calcium phosphate, calcium stearate, carmellose- Sodium, cellulose, cellulose derivatives, dimeticon, dyes, gelatin, glucose syrup, highly disperse silicon dioxide, hypromellose, potassium benzoate, lactose monohydrate, macrogol, magnesium carbonate, magnesium oxide (light), magnesium stearate, maize starch, maize starch, mannitol, mannitol, mono- and diglycerides of fatty acids, montanglycol wax, sodium benzoate, sodium carbonate (anhydrous), sodium chloride, sodium hydrogen carbonate, poly (butyl methacrylate co- (2-dimethyIaminoetJ ⁇ yl methacrylate), polyvidone K 25
