Abstract:
A solid drug form containing not less than 90% by weight verapamil is produced by granulating at from 30.degree. to 55.degree. C. with a little water, drying and, where appropriate, conventional tableting or by pelleting, in which case the granules obtained as described are, after cooling, moistened once again and compacted in a granulating mixer at from 30.degree. to 55.degree. C. and are dried.
Abstract:
In an apparatus for removing portions of identical materials (4) in the form of pieces by means of a sliding part which is encased in a dispensing container and operated from the outside and whose dispensing sector (5) is filled from inside the container and can be emptied outward, the sliding part is in the form of a tube section (1) which has one or more dispensing sectors (5) and is fed through an outer shell (3) and a stripper (2) located adjacent to the ejection orifice (9) and assigned to the dispensing sectors (5).
Abstract:
Cylindrical microtablets which have a convex upper face and a convex lower face and whose cylinder diameter and height independently of one another are each from 1.0 to 2.5 mm and the ratio of the said diameter to said height is from 1:0.5 to 1:1.5, and a process for their preparation.
Abstract:
In order to prevent impairment of the pharmacological effect of pancreatine through added auxiliary substances or binding agents a pancreatine pellet consists exclusively of pancreatine.
Abstract:
In order to avoid compromising the pharmacological effect of pancreatin caused by the addition of auxiliary materials or binding agents, a pancreatin pellet having a 100% pancreatin content consists exclusively of pancreatin with a residual moisture content of less than 3% by weight, preferably less than 1% by weight or less than 0.5% by weight.
Abstract:
The invention relates to a method for reducing the viral and microbial content of biological extracts which contain solids. It is provided that the method comprises the steps (a) provision of the biological extract which contains solids, comprising a biologically active substance, selected from enzymes, proteins and peptides, or a mixture of such substances; and (b) subjecting the biological extract provided in step (a) to a high-pressure treatment; wherein the biological activity of the biological extract which contains solids after the high-pressure treatment is at least 50% of the biological activity of the biological extract which contains solids before the high-pressure treatment.
Abstract:
The invention relates to a method for producing pancreatin with reduced viral and microbial contamination, comprising the steps of (a) providing the pancreatin in solid form with a residual moisture of 0.5 weight % or less, down to almost zero, based on the pancreatin provided; (b) subjecting the pancreatin provided in step (a) to a heat treatment at a temperature of 84° C., preferably 80° C. and below; wherein, the biological activity of the pancreatin obtained in step (b) corresponds to at least 50% of the biological activity of the pancreatin provided in step (a); and the viral infectiousness of the pancreatin obtained in step (b) has been reduced by a factor of more than 1 log10 in comparison with the viral infectiousness of the pancreatin provided in step (a), as well as a pancreatin produced according to this method and its use for producing a medicine or a nutritional supplement.
Abstract:
A solid pharmaceutical sustained-release form, consisting of a core containing the active compound as well as conventional pharmaceutical auxiliaries, a coat which delays the release of the active compound and an antiadhesive outer layer, wherein the coat consists of a physiologically acceptable fat-like or wax-like hydrophobic layer which melts in the range from 30.degree. to 120.degree. C. and contains, in addition to conventional pharmaceutical auxiliaries, one or more water-insoluble polymers, and a process for its preparation.
Abstract:
A process for the preparation of solid pharmaceutical products, wherein, in a first step, spherical single crystals of a pharmaceutical active compound or assistant are prepared by agitating a saturated aqueous, organic or organic-aqueous solution in high speed stirred crystallizers or draft-tube crystallizers at 50-500 revolutions per minute and seeding the solution with finely ground seed crystals of particle size less than 100 .mu.m, while ensuring that at the time of addition of the seed crystals and during the growth thereof the solution is at all times only minimally supersaturated, this being achieved by slow cooling at a rate of not more than 50 K/h or corresponding slow evaporation of the solution, and in a second step the resulting spherical single crystals with diameters of 0.1-3 mm, preferably 0.5-2 mm, are separated from the solution, dried at 40.degree.-200.degree. C., compounded, where appropriate, with suitable pharmaceutical assistants or, if the single crystals serve as assistants, with suitable pharmaceutical active compounds, and then converted to solid pharmaceutical products by coating, tableting or filling into hard gelatin capsules.
Abstract:
A stringently sodium-restricted dietetic salt consisting of a mixture of from 60 to 85% by weight of potassium chloride, from 10 to 30% by weight of potassium adipate, from 2 to 5% by weight of potassium tartrate, from 0.5 to 2% by weight of potassium glutamate, from 0.5 to 2% by weight of adipic acid and a total of from 0.004 to 0.06% by weight of potassium inosate and/or potassium guanylate, and the preparation of the salt in a fluidized bed apparatus.
