Abstract
A semi-paste oral preparation comprises, as effective ingredients, at least 0.1 to 20% by weight of povidone-iodine based on the total weight of the preparation, and 0 to 50 parts by weight of potassium iodide and 1 to 300 parts by weight of a sugar alcohol of an oligosaccharide as a base and stabilizer, the parts by weight being based on one part by weight of the povidone-iodine. This semi-paste oral preparation has a modest viscosity, good taste and good stability upon storage for a long time.
Claims12
A pharmaceutically stable povidone-iodine semi-paste oral preparation comprising at least from about 0.1 to about 20% by weight of povidone-iodine based on the total weight of the preparation, about 0 to about 50 parts by weight of potassium iodide and from about 1 to about 300 parts by weight of a pharmaceutically stable base comprising a substantially fully reduced oligosaccharide;
- wherein said base is substantially less reactive with said povidone-iodine relative to the reactivity of non-reduced oligosaccharide with PVI, and said preparation is homogeneous and pharmaceutically stable relative to an equivalent formulation comprising a non-reduced oligosaccharide.
