The invention provides ibuprofen and ibuprofen containing pharmaceutical preparations stabilized against thermal degradation by the presence of a phenolic type antioxidant.

A method is provided for the preparation of ibuprofen by carbonylating 1-(4'-isobutylphenyl)ethanol (IBPE) with carbon monoxide comprising initially a reaction mixture comprising IBPE, ibuprofen and a catalyst for the carbonylation with carbon monoxide under conditions to initiate the reaction, and continuing to feed carbon monoxide to the composition to produce the desired yield of ibuprofen. Preferably the catalyst comprises palladium and a monodentate phosphine ligand. The presence of ibuprof...

This invention relates to pharmaceutical compositions for use in the treatment of pain and inflammation and the relief of cough and cold symptoms in a mammalian organism, said composition comprising: (i) an analgesically and anti-inflammatory effective amount of (S)-ibuprofen, or a salt thereof, substantially free of (R)-ibuprofen; and (ii) an antitussively effective amount of at least one antitussive agent selected from codeine, hydrocodone, caramiphen, carbetapentane, or dextromethorphan, or a...

An ibuprofen-containing antipyretic analgesic preparation blending 0.01-30 parts by weight of acetaminophen based on 1 part by weight of ibuprofen, 0.05-100 parts by weight of magnesium-based antacids based on 1 part by weight of the total amount of ibuprofen and acetaminophen, and/or 0.01-30 parts by weight of at least one sedative selected from bromovalerylurea and allylisopropylacetylurea based on 1 part by weight of ibuprofen.

A process for treating the blood-brain barrier by the systemic administration of ibuprofen (p-isobutylhydratropic acid) or a salt or ester thereof. Dosage forms are also disclosed.

Ibuprofen p-hydroxybenzaldehyde semicarbazone ester having the formula II: ##STR1## was prepared from the free acid, ibuprofen [.+-.2-(p-isobutylphenyl)propionic acid] (I). The ester II above has the anti-inflammatory activity of the free acid, but in contradistinction to it, it has a pleasant taste, suitable for oral administration such as uncoated tablets, suspensions or syrups, for the treatment of inflammatory conditions, particularly arthritis.

A stable pharmaceutical composition comprising a mixture of (i) an ibuprofen medicament; (ii) a domperidone medicament and (iii) a carrier material characterized in that the carrier material is substantially free of providone and comprises at least one diluent combined with at least one release modifying agent.

The invention concerns coated particles based on granulated microcrystals of ibuprofen, its pharmaceutically acceptable isomers and salts, characterized in that they comprise a coating obtained in a fluidized bed apparatus with a hydroalcoholic dispersion consisting of a mixture comprising (A) 5 to 50% by weight of ethylcellulose relative to ibuprofen; (B) 10 to 60% by weight of hydroxypeopylmethylcellulose relative to the ethylcellulose; and (C) 1 to 40% by weight of silica with antistatic and ...

This invention provides a simple method for preparing granular ibuprofen microsphere whose surface is coated with acrylic acid resin. By this method granulation of ibuprofen and coating of its surface can be simultaneously accomplished. Namely, the method of preparation includes the steps of: (a) dissolving ibuprofen with acrylic acid resin into lower aliphatic alcohol, acetone, methylene chloride or N,N-dimethylformamide; and (b) depositing coated granular ibuprofen microsphere by mixing the so...

Disclosed herein is a novel process for producing Sodium dihydrate salt of Ibuprofen of Formula (Structure I) by treating a salt of long chain carboxylic acid of Formula (Structure III) with Ibuprofen of Formula (Structure II) in the presence of an aqueous organic solvent.
