Abstract: Carrier particles, for use in the preparation of powdery mixtures for administration by inhalation, and having a median diameter of greater than 90 microns and a surface rugosity expressed as the fractal dimension of less than or equal to 1.1, may be prepared by subjecting particles having a median diameter of greater than 90 microns to repeated stages of wetting with a solvent and drying.

Abstract: In a solution composition for use in an aerosol inhaler which comprises an active material, a propellant containing a hydrofluoroalkane, a cosolvent and optionally a low volatility m compound the use of a mixture of HFA 134a and HFA 227 allows to modulate the mass median aerodynamic diameter (MMAD) of the aerosol particles on actuation of the inhaler to target specific regions of the respiratory tract. Moreover the fine particle dose (FPD) of the active ingredient in the composition increases by reducing the metering chamber volume.

Abstract: Carriers for use in the preparation of mixtures for inhalation powders intended for pulmonary administration of micronized drugs by means of a dry powder inhaler and the method for their preparation are described.

Abstract: A pharmaceutical composition in the form of effervescent tablets comprising an active ingredient and an effervescent blend, comprising an acidic component and sodium glycine carbonate as alkaline components. Preferred acid components are fumaric acid, maleic acid, and their salts. Tablets are prepared in normal thermohygrometric conditions and with standard tabletting equipment. A pre-granulation process is also disclosed.

Abstract: The invention relates to the use of pressurised metered dose inhalers (MDIs) having part or all of their internal surfaces consisting of stainless steel, anodised aluminium or lined with an inert organic coating; and to compositions to be delivered with said MDIs.

Abstract: The invention relates to carrier particles for use in pharmaceutical compositions for the pulmonary administration of medicaments by means of dry powder inhalers. In particular, the invention relates to a novel technological process for obtaining a carrier modified so as to improve the efficiency of redispersion of active particles and hence increase the respirable fraction. After the treatment of the invention, the surface of said modified carrier particles can also be coated with a suitable additive so as to further improve the respirable fraction.

Abstract: Pharmaceutical compositions which contain a corticosteroid, a propellant, a cosolvent, and an antioxidant are useful for the treatment of bronchial disorders by administration via a pressurized metered dose inhaler.

Abstract: Powdery pharmaceutical compositions including an active ingredient and carrier particles containing only a small amount of lubricant, 0.05-0.5% by weight, are used to prepare dry powder inhalers in order to increase the fine particle dose. A process for coating the surface of the carrier particles with such little amount of lubricant is also provided. Use of limited amount of lubricant is safe and provides ordered stable mixtures without segregation of the active particles during handling and before use.

Abstract: Powdery pharmaceutical compositions including an active ingredient and carrier particles containing only a small amount of lubricant, 0.1-0.5% by weight, are used to prepare dry powder inhalers in order to increase the fine particle dose. A process for coating the surface of the carrier particles with such little amount of lubricant is also provided. Use of limited amount of lubricant is safe and provides ordered stable mixtures without segregation of the active particles during handling and before use.

Abstract: A process for the preparation of compounds of formula (I), wherein R is C2-C20 linear or branched alkyl, C3-C7 cycloalkyl, phenyl or benzyl, which can optionally be substituted by C1-C4 alkyl, halogen or C1-C4 alkoxy group, said process comprising: a) oxidation of eserine with hydrogen peroxide in the presence of a base and subsequent hydrolysis to geneseroline, without isolating the intermediate geneserine; b) acylation of geneseroline with an isocyanate of formula R—N═C═O, wherein R is as defined above, in the presence of a basic catalyst; c) optional transformation into a pharmaceutically acceptable salt. Compounds of formula (I) wherein R is a phenyl or benzyl, which can be optionally substituted by alkyl, halogen or alkoxy, are selective, potent brain anticholinesterase inhibitors.
