摘要:
A pharmaceutical combination for minimizing pharmacokinetic drug-drug interaction is described including a first pharmaceutical component having a particular pharmacokinetic profile in a mammal and a second pharmaceutical component formulated for parenteral administration having an altered pharmacokinetic profile different from the unaltered pharmacokinetic profile of the second pharmaceutical component, which would interfere with the pharmacokinetic profile of the first pharmaceutical component. Due to its altered pharmacokinetic profile, the second pharmaceutical component does not substantially affect the pharmacokinetic profile of the first pharmaceutical component.

摘要:
A method for enhancing the oral bioavailability of a prodrug ester by formulating the ester as a non-emulsified formulation with lecithin; as well as a pharmaceutical composition of at least one antibiotic and lecithin in a non-emulsified formulation; a method of treating infections with the non-emulsified formulation, and a method for preparing tablets by direct compression of blends of drugs with lecithin are disclosed. Non-emulsified formulations include solids, tablets, capsules, lozenges, suspensions, elixirs and solutions, and exclude emulsions, liposomes, lipid matrix systems and micro-emulsions. A suitable prodrug ester is a cephalosporin β-lactam antibiotic such as cefditoren pivoxil, and a suitable non-emulsified formulation is a solid formulation.

摘要:
The present invention relates to a process for the preparation of novel, partially crystalline polyether polyols with a functionality of ≧2, an average molecular weight Mn of 500 to 100,000 and a molar proportion of isotactic triads determining the crystallinity of >28%. The new polyether polyols are prepared by polymerizing alkylene oxides in the presence of a bimetallic :-oxoalkoxide modified with hydroxyl compounds.
摘要:
The present invention relates to highly active, substantially crystalline double metal cyanide (DMC) catalysts, a process for the preparation of these double metal cyanide catalysts, a process for producing polyether polyols by the polyaddition of alcohol ethers onto starter compounds containing active hydrogen atoms from these DMC catalysts, and to the polyether polyols produced by this process. The DMC catalysts of the invention comprise a) double metal cyanide compounds, b) organic complexing ligands, and c) functionalized polymers. These catalysts exhibit increased activity in the process for the production of polyether polyols.
摘要:
Low-odor, higher molecular weight polyether polyols are produced by purifying the polyether polyols at temperatures of 110.degree. to 150.degree. C. and pressures of 10 to 70 hPa with the addition of 5 to 30% by weight of water, wherein the water is passed in finely divided form, with a droplet diameter of about 5 to 100.mu., through the polyether polyols to be purified for a time of metered addition of 1 to 5 hours.
