摘要:
An object of the present invention is to provide an easily absorbable oral preparation containing a xanthine derivative or a pharmaceutically acceptable salt thereof and a fatty acid or a fatty acid derivative for the purpose of providing an easily absorbable oral preparation containing the xanthine derivative of which absorbability has been enhanced by dissolving the xanthine derivative that shows adenosine A1 receptor antagonistic activity and has diuretic activity, kidney-protecting activity, bronchodilating activity, cerebral function-improving activity, anti-dementia activity or the like in a solvent.

摘要:
The present invention provides a method of producing coated fine particles in which core fine particles is coated with a coating layer, which comprises the steps of preparing a liquid (liquid A) containing a polar organic solvent in which core fine particles are dispersed and a component constituting a coating layer is dissolved; preparing a liquid (liquid B) which is miscible with the liquid A and does not contain a polar organic solvent or contains a polar organic solvent in a ratio lower than that in the liquid A; and letting the liquid A flow from at least one inlet of a device for producing coated fine particles equipped with an in-line mixing means having two or more inlets and one or more outlet(s) and letting the liquid B flow from at least one remaining inlet to mix the liquids thereby coating the core fine particles with the coating layer.
