摘要:
Thyroxine containing pharmaceutical compositions with improved aqueous solubility, stability and enhanced membrane permeation have been prepared by formulating thyroxine with cyclodextrins. These thyroxine/cyclodextrin complexes can further be transformed into different dosage forms (oral tablets, injectables, transdermal patches, hydrogels, ointments, suppositories, etc.) by employing known, common pharmaceutical additives.
摘要:
The invention concerns a slow-release tablet containing diclofenac-Na as the active ingredient and methylhydroxypropylcellulose as the retarding agent.
摘要:
The present invention relates to a method for analysing protein variants of a recombinant protein of interest, such as antibodies or Fc-fusion proteins, in a liquid sample of a mammal. Specifically the method comprises a step of affinity purifying the recombinant protein of interest from the sample together with an internal standard, and analyzing the protein variants using an analytic separating method such as HPLC, capillary electrophoresis or MS. This method is particularly suited to measure pharmacokinetic parameters of a recombinant protein of interest, such as a biopharmaceutical, in a mammal in clinical or pre-clinical studies. It allows for the use of a small sample volume and the possibility to operate with high throughput, such as in a 96-well plate sample preparation. It also provides high sensitivity and allows analysis of protein variants individually.
摘要:
The present invention relates to a solid pharmaceutical composition comprising atorvastatin or a salt thereof, in particular to a composition having the total weight of less than or equal to 600 mg and a tablet comprising said composition. The present invention furthermore relates to a process for the preparation of solid composition comprising atorvastatin or a salt thereof and its use as a medicament, especially for the treatment of hypercholesterolemia or hyperlipidemia.
摘要:
The present invention relates to a method for analyzing glycans of a recombinant glycoprotein in a liquid sample of a mammal. Specifically the method comprises a step of affinity purifying the recombinant glycoprotein from the sample, enzymatically releasing a glycan containing fragment from the immobilized glycoprotein, adding a reference standard containing isotopically labeled glycans, fluorescently label the glycans and analyzing the glycans using LC-MS. The present invention also relates to a method further comprising analyzing the glycans of the immobilized recombinant glycoprotein fragment, further comprising a pre-clearing step of the liquid sample, and releasing the glycans from the immobilized recombinant glycoprotein fragment. The methods allow for the use of a small sample volume and the possibility to operate with high throughput, such as in a 96-well plate sample preparation and are therefore suited to measure pharmacodynamics parameters of a recombinant glycoprotein in a mammal in clinical or pre-clinical studies.
摘要:
The present invention relates to an oral pharmaceutical composition comprising dabigatran etexilate or a pharmaceutically acceptable salt thereof, methods for preparing it and dosage forms for oral administration comprising said composition. The pharmaceutical composition is parfcularly useful as a medicament, especially as anticoagulant.
摘要:
The present invention uses anthranilic acid (2-AA) to label N-glycans prior to separation using a reversed-phase liquid chromatography (RP-LC) column under acidic conditions using formic acid. Negatively charged 2-AA offers stronger retention on the reversed phase column than 2-aminobenzamide (2-AB) in RP-LC and allows efficient ionization and detection of 2-AA labeled N-glycans. The acidic conditions used for the RP-LC leads to an efficient separation of acidic 2-AA N-glycans carrying terminal sialylation without the need for an ion-pairing reagent.
