In particular, the compositions are intended for buccal and/or sublingual delivery. The invention is particularly suitable for administering therapeutically active agents which have an effect on the central nervous system and even more particularly where rapid onset of this effect is desired or beneficial. The invention is also particularly suitable for administering active agents in low solubility base or acid forms. | 06-24-2010 |
20100209358 | Method of Making Particles For Use In A Pharmaceutical Composition - The invention relates to a method for making composite active particles for use in a pharmaceutical composition for pulmonary administration, the method comprising a milling step in which particles of active material are milled in the presence of particles of an additive material which is suitable for the promotion of the dispersal of the composite active particles upon actuation of an inhaler. The invention also relates to compositions for inhalation prepared by the method. | 08-19-2010 |
20100273760 | Topical Pharmaceutical Formulations And Methods Of Treatment - In certain embodiments, the present invention is directed to a pharmaceutical formulation for topical administration on a mammal, comprising a unit dose of a therapeutically effective amount of a therapeutic agent and a pharmaceutically acceptable carrier medium therefor, said formulation being solid at ambient temperature and having a softening point of not higher than 35° C., such that when the formulation is placed in continuous contact with the skin of a mammalian patient, it is softened to a consistency to effect substantial application of the unit dose of said therapeutic agent onto a desired skin area of the mammalian patient within a time period of less than 10 minutes. | 10-28-2010 |
20100285142 | Method Of Making Particles For Use In A Pharmaceutical Composition - A method for making composite excipient particles for use in a pharmaceutical composition comprises a milling step in which particles of an excipient material are milled in the presence of an additive material. The product particles are of small size and the milling requires relatively low input of time and energy. The composite particles are suitable for use in inhalable pharmaceutical compositions. | 11-11-2010 |
20100330188 | CARRIER PARTICLES FOR USE IN DRY POWDER INHALERS - A powder for use in a dry powder inhaler includes active particles and carrier particles for carrying the active particles. The powder further includes additive material on the surfaces of the carrier particles to promote the release of the active particles from the carrier particles on actuation of the inhaler. The powder is such that the active particles are not liable to be released from the carrier particles before actuation of the inhaler. The inclusion of additive material in the powder has been found to give an increased respirable fraction of the active material. | 12-30-2010 |
