Abstract: A controlled release composition including spheroid cores of diltiazem. or a pharmaceutically acceptable salt thereof and optionally a spheronizing agent, the cores being coated with a controlled release layer, and a method of manufacturing the same, is disclosed. The spheronizing agent when present is preferably microcrystalline cellulose. Ethylcellulose is a preferred release coating. The controlled release coating preferably contains a plasticizer, a surfactant and a tack-modifier.

Abstract: A solid oral dosage form comprising diltiazem (or a pharmaceutically acceptable salt thereof) in controlled release form and hydrochlorothiazide in immediate release form. Preferably, the controlled release component comprises a plurality of spheroids comprising diltiazem and a spheronizing agent.

Abstract: The invention relates to a lousicidal shampoo composition of phenothrin as lousicidal agent distributed in a shampoo base of water and one or more surface active agents, the shampoo containing as antimicrobial preservative 2-bromo-2-nitropropane-1,3-diol alone or in combination with 2,4-dichlorobenzyl alcohol.

Abstract: An ion exchange resin composition which is readily dispersible in water is provided. This resin composition comprises a granulated ion exchange resin, a pharmacologically active ingredient bound thereto with a sugar or sugar alcohol, and a sufficient amount of water, alcohol or aqueous alcohol to facilitate granulation. The invention further comprises a method for the preparation of such ion exchange resin composition.

Abstract: Iodophor-containing suppositories are provided with improved rate of iodine release from the suppository. The suppository composition comprises an iodophor, a water soluble suppository base, at least one water soluble sugar having a molecular weight of between about 90 and 550, and water in an amount of at least about 30% by weight. The molecular weight of the sugar is preferably between about 150 and 370. The preferred iodophors are providone iodine and polydextrose iodine. The preferred suppository bases are gelling polysaccharides and the preferred sugars are monosaccharides, disaccharides and sugar alcohols. The rate of iodine release is improved because of the high concentration of water together with the presence of the low molecular weight sugar.

Abstract: Solid shaped articles, particularly rapidly dissolving pharmaceutical dosage forms, carrying predetermined unit quantities of chemicals are prepared by a novel process involving the addition of the predetermined amount of chemical in a solvent to a placebo article which contains a network of carrier material. The placebo article is prepared by freezing a composition of carrier material in a solvent and subliming the solvent from the frozen composition.

Abstract: Spherical frozen particles, which may be subsequently freeze dried are prepared by introducing a liquid medium in the form of droplets beneath the surface of a cooling liquid. The temperature and density of the cooling liquid is chosen so that liquid droplets freeze as they float towards the surface of the cooling liquid. Preferably a column of cooling liquid is employed and the liquid medium is introduced through an inlet near the base of the column.
