Abstract: A sustained release suppository comprising in a usual suppository basea) a water-soluble therapeutically active substance, the average particle size of which is smaller than 20 .mu.m,b) a physiologically acceptable organic substance which is swellable in contact with water, andc) hydrophobic silicium dioxide.The suppository base is usually a fat having a melting range of from 29.degree. to 38.degree. C. As ingredient b) cellulose derivatives such as hydroxypropylmethylcellulose may be used, in a quantity of from 5 to 40% by weight, preferably 9 to 15% by weight. Ingredient c) is preferably used in a quantity of from 3 to 6% by weight. Also a process for manufacturing the suppositories is described.

Abstract: This invention relates to an ophthalmic preparation of povidone iodine in a packaging of bottle glass type I or polyethyleneterephthalate with a dropper of polypropylene, polyethylene and/or polytetrafluoroethylene coated bromobutyl rubber.

Abstract: A solid iodophor composition contains a water-soluble iodophor, especially povidone iodine, and at least one of a urea and a sugar alcohol, especially mannitol, sorbitol or xylitol. The composition may also contain a sugar such as sucrose or lactose.The advantage claimed in the ready solublility of the composition in water. This would allow the supply of iodophors in solid, rather than liquid, form.

Abstract: A free flowing iodophor powder which can be used for the treatment of wounds and the like, is prepared by spraying a solution of the iodophor in an aqueous-alcoholic solvent having a boiling point at normal pressure of less than 100.degree. C. into a fluidized bed of a finely divided sugar. This results in the formation of a free flowing powder which is well tolerated upon application to wounds.
