The present invention relates to an process for the preparation of ibuprofen, which comprises reacting para isobutyl phenylethanol (p-IBPE), a halide source, a protonic acid, water and the catalyst which is a compound having formula 1 which is shown herebelow: ##STR1## Wherein M = a group VIII metal specifically palladium or platinum, R.sub.1, R.sub.2, R.sub.3 = substituents on the phosphine ligand such as hydrogen, alkyl, aryl, arylalkyl cycloaliphatic, X = groups such as aryl or alkyl sulphona...

Ibuprofen p-hydroxyphenylurea 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.

This disclosure is directed to preparation of individual taste-masked, high bioavailability, high payload, microcapsules by microencapsulation of water-insoluble NSAID drug materials in the substantial absence of microcapsule agglomerates. These taste-masked microcapsules contain a high payload, e.g., about 83+ wt. % of said NSAID drug material having high bioavailability and can then be formulated into chewable tablets and liquid aqueous suspensions for medicinal use. Both cellulose acetate pht...

This invention discloses organoleptically acceptable formulations containing S(+)-2-(p-isobutylphenyl)-propionic acid, also known as S(+) ibuprofen.

Complexes of ibuprofen and copper and/or zinc were solubilized in ammoniacal solution providing preservative solutions that fully penetrate wood. With loss of the ammonia from the wood, the complexes were stably retained in the wood providing a long lasting preservative.

Provided herein are compositions and methods of making compositions of ibuprofen in combination with a narcotic analgesic. Specifically provided is a pharmaceutical tablet composition comprising ibuprofen; a narcotic analgesic; colloidal silicon dioxide; a filler selected from the group consisting of microcrystalline cellulose and powdered cellulose; a disintegrant selected from the group consisting of croscarmellose sodium, crospovidone, and sodium starch glycolate; a binder consisting of an ak...

A process for the production of S(+)-ibuprofen-particles having improved flow properties comprises the steps that coarse-crystalline S(+)-ibuprofen is molten and then in a molten condition is finely distributed in a non-solving medium, preferably in cold water, and is chilled therein. This chilling results in a fine-crystalline primary structure that agglomerates to a secondary structure. In this agglomerate form the product is obtained which is filtered out and is dried. Such particles are suit...

Pharmaceutical compositions of nalbuphine and ibuprofen have been found to exhibit unexpectedly enhanced analgesic activity by applying an analysis model which considers data characterizing the analgesic effect of both the pure components as well as the fixed dose ratio combinations. This synergism enables the use of lower doses of either or both drugs with a concomitant reduction in risk of possible side effects.

Aluminum ibuprofen pharmaceutical liquid suspensions having improved resistance to dissolution rate reduction upon storage containing aluminum ibuprofen, a suspending agent have a particle size below 50 microns, a water-soluble surface active agent, water, and preferably also from 5 to 30 grams of sucrose per 100 ml of suspension are disclosed, or its sweetening equivalent of glucose, fructose, sodium saccharin sodium cyclamate, or mixtures thereof.
