摘要:
The invention relates to solid drug forms obtainable by extrusion with subsequent shaping of a solvent-free melt, comprising, besides one or more active ingredients, A) 10-90% by weight of a melt-processable, water-soluble polymer, B) 5-85% by weight of isomalt, and C) 0-5% by weight of lecithin, where the total of all the ingredients is to be equal to 100% by weight.
摘要:
A process for the production of divisible tablets by melt calendering in which two molding rolls are combined together, at least one of which has depressions with at least one bar which extends up to the surface line of the molding roll and forms a score.
摘要:
A process for producing active substance compositions in the form of a solid solution of the active substance in a polymer matrix, which comprises melt extrusion of the active substance in nonionic form together with a polymer and a salt.
摘要:
A process with whose aid active substances of low solubility can be processed together with phospholipids to give a homogeneous solution, which comprisesa) mixing the active substance with a phospholipid,b) adding an acidic aqueous solution of a carbohydrate to the residue at elevated temperature, and stirring this mixture at elevated temperature until a homogeneous colloidal solution is produced, andc) cooling the solution, and adjusting to a pH of 4-5 and sterilizing is described.
摘要:
A process for preparing an aqueous active substance solution which can be sterilized by filtration entails mixing anipamil hydrochloride with a phospholipid in the ratio of from 1:2 to 2:1 by weight, converting the resulting mixture into a gel by adding water at elevated temperature, and subsequently adding water to the gel at elevated temperature until the active substance is present in the required concentration.
摘要:
A process is described for the production of solid forms of active substances, which forms have good redispersibility in aqueous systems, which comprises mixing PEG and dextran with water and--if phase separation occurs--removing the upper phase, dissolving an active substance in the mixture, where appropriate adding a physiologically tolerated amphiphile, and subsequently removing the water.
