Abstract: The use of a granular material which is for orally fast disintegrating tablets and comprises starch and tannic acid allows provision of tablets that can be produced by a simple process with general-purpose production equipment, disintegrate fast and absorbs water in the mouth, and have a proper level of shape retainability for practical use. The present invention also provides a method for producing an orally fast disintegrating tablet, the method comprising compression molding of a granular material for orally fast disintegrating tablets comprising starch and tannic acid, or a mixture of the granular material for orally fast disintegrating tablets and other ingredients (an additive, an active ingredient, and/or the like).

Abstract: The use of a granular material which is for orally fast disintegrating tablets and comprises at least one kind of water soluble polymer and tannic acid allows production of tablets that can be produced by a simple process with simple production equipment, disintegrate fast in the mouth, and have a proper level of moldability for practical use. The at least one kind of water soluble polymer is preferably selected from the group consisting of povidone, hydroxypropyl cellulose, pullulan, a polyvinyl alcohol-polyethylene glycol graft copolymer and copolyvidone.

Abstract: It is intended to provide an eye drop preparation capable of preventing not only degradation of latanoprost in water but also adsorption of latanoprost onto a plastic container so that a decrease in latanoprost content thereof is satisfactorily prevented. The eye drop preparation contains an ophthalmic solution composition containing components (A) and (B) and packed in a plastic container: (A) latanoprost; and (B) a nonionic surfactant.

Abstract: Disclosed is an eye drop preparation comprising latanoprost, which is characterized in that the degradation of latanoprost in water can be prevented, the adsorption of latanoprost onto a plastic container can be prevented, and therefore the decrease in the latanoprost content can be prevented satisfactorily. The eye drop preparation comprises an eye drop composition comprising the following components (A)-(B) and packed in a plastic container: (A) latanoprost; and (B) a nonionic surfactant.
