摘要:
The invention provides a method of making a composition for inhalation which includes the step of mixing particles of additive material having a diameter of not more than 2 μm with active particles, wherein the additive material is suitable for promoting the dispersal of active particles upon aerolization of a dry, powder in a dry powder inhaler.
摘要:
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.
摘要:
The invention provides microparticles for use in a pharmaceutical composition for pulmonary administration, each microparticle comprising a particle of an active substance having, on its surface, particles of a hydrophobic material suitable for delaying the dissolution of the active substance. The invention also provides a method for making the microparticles.
摘要:
A composition, device, and method for treating sexual dysfunction via inhalation is provided which comprises inhaling a dose of apomorphine or pharmaceutically acceptable salt(s) or ester(s) thereof.
摘要:
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.
摘要:
The present invention relates to pharmaceutical compositions and their uses in therapy. In particular, the invention relates to compositions comprising methotrexate, preferably wherein the compositions are for administration via the inhaled or intranasal route.
摘要:
A pharmaceutical formulation for delivery in aerosol or spray form, comprising a liquefied propellant gas, a solid particulate pharmaceutically active agent and a dispersing agent, wherein the dispersing agent is fused to the surface of particles of the pharmaceutically active agent.
摘要:
A mouthpiece for use in an inhaler for a particulate medicament, the mouthpiece having: an inlet and an outlet for the particulate medicament; a number of abutments which extend across the mouthpiece and which are arranged in a staggered configuration such that, in use, medicament is caused to break up as the medicament passes through the mouthpiece; wherein the abutments are blades having an elongate cross section in the direction of travel of the medicament.
摘要:
A fire suppressant powder with particle sizes less than 5 .mu.m is made by a chemical reaction between a gas or vapour of a first material and a vapour or an aerosol of a second material. For example an aerosol of sodium hydroxide droplets may be reacted with carbon dioxide gas to produce sodium bicarbonate powder; or boron halide vapour may be reacted with steam to form boric acid powder The powder may be used in fire extinguishers either on its own, or combined with other ingredients such as silica and/or alumina, and calcium stearate.
