Abstract:
A pharmaceutical composition for parenteral administration having anti-inflammatory and analgesic properties which contain, as active principle, alkylammonium salts of 2-arylpropionic acids.
Abstract:
The present invention relates to the use of effervescent tablets containing insoluble active principles for the preparation of a suspension for inhalatory use that retain the primary particle size of the drug substance. The tablets dissolve in the solution until a fine suspension is obtained. The suspension maintains the initial particle size distribution of the drug substance, ensuring the achievement of the therapeutic window of the aspired fraction.
Abstract:
A process for the sterilization of water insoluble solid medicinal substances is described.The process provides the sterilization of drug substances, which are suitable for pulmonary administration. In particular, the process is used in industrial plants for the production of formulations of sterile glucocorticoids for inhalation delivery, so as to avoid any modifications in particle size distribution and in the impurities profile of the drug. the process is carried out by heating a mixture of micronized glucocorticoid and purified water only, preferably at a temperature of about 120° C for 20 minutes. The process is particularly efficient and economic for the steam sterilization of beclomethasone dipropionate in formulations for pulmonary delivery.
Abstract:
The present invention relates to the use of amides of (R) and (S)-2-aryl- propionic acids as antiseptic agents. The present invention also provides a pharmaceutical preparation including compounds of formula (I), having antiseptic properties for the treatment of gastrointestinal, muco-epidermal and epidermal infections. The present invention is related to pharmaceutical compositions containing an antiseptic agent carried in a suitable vehicle to provide mouthwashes, tablets, solutions, gels, creams and others. The formulations are applied topically to sites of gastrointestinal, muco-epidermal or epidermal infections. Compounds of present invention can be useful in the treatment of nausea, vomiting, bloating, diarrhea, constipation and oropharyngeal, esophageal, vaginal, rectal, nasal and other mucosal infections.

Abstract:
A process for the co-precipitation of a substance with a stabiliser therefor, by a gas anti solvent process comprising introducing into a particle formation vessel a supercritical fluid pure or mixed with a modifier; and a solution comprising said substance and said stabiliser dissolved in a solvent; so as said solvent is extracted from the solution by said supercritical fluid and co-precipitation of the substance and stabiliser occurs. The process may be carried out using an apparatus comprising a particle formation vessel (22) and a nozzle (27) having a central orifice (39) serving to introduce a solution of the substance and a plurality of outer orifices (41) serving to carry a flow of supercritical fluid into the particle formation vessel (22), such that the solvent is extracted from the solution by the supercritical fluid and precipitation of micron sized particles of the substance/stabilizer occurs. The substance is preferably a protein of pharmaceutical interest, which is highly stabilized for storage by this process.

Abstract:
Pharmaceutical compositions are described, containing an alkylammonium salt of a 2-arylpropionic acid, which are suitable for parenteral administration and do not generate pain upon injection. The compositions contain preferably ketoprofen, ibuprofen, naproxen or tiaprofenic acid in aqueous solution at pH in the range between 8 and 9. The alkylammonium salt is preferably a L-lysine salt. Compositions at pH=8,5 have shown to cause less pain upon injection than other known compositions.
